CAUTIONARY NOTE REGARDING FORWARD-LOOKING STATEMENTS

In addition to the historical information contained in this report, this report contains (and oral communications made by IDACORP, Inc. (IDACORP) and Idaho Power Company (Idaho Power) may contain) statements that relate to future events and expectations, such as statements regarding projected or future financial performance, cash flows, capital expenditures, dividends, capital structure or ratios, load forecasts, strategic goals, challenges, objectives, and plans for future operations. Such statements constitute forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995. Any statements that express, or involve discussions as to, expectations, beliefs, plans, objectives, assumptions, or future events, or performance, often, but not always, through the use of words or phrases such as "anticipates," "believes," "could," "estimates," "expects," "intends," "potential," "plans," "predicts," "preliminary," "projects," "may," "may result," "may continue," or similar expressions, are not statements of historical facts and may be forward-looking. Forward-looking statements are not guarantees of future performance and involve estimates, assumptions, risks, and uncertainties that may differ materially from actual results, performance, or outcomes. In addition to any assumptions and other factors and matters referred to specifically in connection with such forward-looking statements, factors that could cause actual results or outcomes to differ materially from those contained in forward-looking statements include those factors set forth in this report, IDACORP's and Idaho Power's Annual Report on Form 10-K for the year ended December 31, 2022, particularly Part I, Item 1A - "Risk Factors" and Part II, Item 7 - "Management’s Discussion and Analysis of Financial Condition and Results of Operations" of that report, subsequent reports filed by IDACORP and Idaho Power with the U.S. Securities and Exchange Commission (SEC), and the following important factors:

•decisions by the Idaho and Oregon public utilities commissions and the Federal Energy Regulatory Commission that impact Idaho Power's ability to recover costs and earn a return on investment;

•changes to or the elimination of Idaho Power's regulatory cost recovery mechanisms;

•expense and risks associated with capital expenditures for, and the permitting and construction of, utility infrastructure projects that Idaho Power may be unable to complete or that may not be deemed prudent by regulators for full cost recovery or full return on investment;

•expenses and risks associated with supplier and contractor delays and failure to satisfy project quality and performance standards, on utility infrastructure projects and the potential impacts of those delays on Idaho Power's ability to serve customers;

•power demand exceeding supply, and the rapid addition of new industrial and commercial customer load and the volatility of such new load demand, resulting in increased costs for purchasing energy and capacity in the market, if available, or acquiring or constructing additional generation and transmission resources, and battery storage facilities;

•impacts of economic conditions, including an inflationary or recessionary environment and increasing interest rates, on items such as operations and capital investments, supply costs and delivery delays, supply scarcity and shortages, population growth or decline in Idaho Power's service area, changes in customer demand for electricity, revenue from sales of excess power, credit quality of counterparties and suppliers and their ability to meet financial and operational commitments, and collection of receivables;

•changes in residential, commercial, and industrial growth and demographic patterns within Idaho Power's service area, and the associated impacts on loads and load growth;

•employee workforce factors, including the operational and financial costs of unionization or the attempt to unionize all or part of the companies’ workforce, the cost and ability to attract and retain skilled workers and third-party contractors and suppliers, the cost of living and the related impact on recruiting employees, and the ability to adjust to fluctuations in labor costs;

•changes in, failure to comply with, and costs of compliance with laws, regulations, policies, and orders including those relating to reliability and security, the environment, climate change, natural resources, and threatened and endangered species, and associated mitigation requirements, which may result in penalties and fines, increase compliance and operational costs, and impact recovery associated with increased costs through rates;

•abnormal or severe weather conditions (including conditions and events associated with climate change), wildfires, droughts, earthquakes, and other natural phenomena and natural disasters, which affect customer sales, hydropower generation, repair costs, service interruptions, liability for damage caused by utility property, and the availability and cost of fuel for generation plants or purchased power to serve customers;

•advancement of self-generation, energy storage, energy efficiency, alternative energy sources, and other technologies that may reduce Idaho Power's sale or delivery of electric power or introduce operational vulnerabilities to the power grid;

Table of Contents

•variable hydrological conditions and over-appropriation of surface and groundwater in the Snake River Basin, which may impact the amount of power generated by Idaho Power's hydropower facilities;

•ability to acquire fuel, power, electrical equipment, and transmission capacity on reasonable terms and prices, particularly in the event of unanticipated or abnormally high resource demands, price volatility, lack of physical availability, transportation constraints, outages due to maintenance or repairs to generation or transmission facilities, disruptions in the supply chain, or credit quality or lack of counterparty and supplier credit;

•disruptions or outages of Idaho Power's generation or transmission systems or of any interconnected transmission systems, which can result in liability for Idaho Power, increase power supply costs and repair expenses, and reduce revenues;

•accidents, electrical contacts, fires (either affecting or caused by Idaho Power facilities or infrastructure), explosions, infrastructure failures, general system damage or dysfunction, and other unplanned events that may occur while operating and maintaining assets, which can cause unplanned outages; reduce generating output, damage company assets, operations, or reputation; subject Idaho Power to third-party claims for property damage, personal injury, or loss of life; or result in the imposition of fines and penalties; insurance coverage for such operating and event risks is subject to the terms and limitations of the available policies and may not be sufficient in amount to cover Idaho Power’s ultimate liability;

•acts or threats of terrorist incidents, acts of war, social unrest, cyber or physical security attacks, and other malicious acts of individuals or groups seeking to disrupt Idaho Power's operations or the electric power grid or compromise data, or the disruption or damage to the companies’ business, operations, or reputation resulting from such events;

•increased purchased power costs and operational and reliability challenges associated with purchasing and integrating intermittent renewable energy sources into Idaho Power's resource portfolio;

•Idaho Power’s concentration in one industry and one region, and the resulting exposure to regional economic conditions and regional legislation and regulation;

•changes in tax laws or related regulations or interpretations of applicable laws or regulations by federal, state, or local taxing jurisdictions, and the availability of tax credits;

•inability to timely obtain and the cost of obtaining and complying with required governmental permits and approvals, licenses, rights-of-way, and siting for transmission and generation projects and hydropower facilities;

•ability to obtain debt and equity financing or refinance existing debt when necessary and on satisfactory terms, which can be affected by factors such as credit ratings, reputational harm, volatility or disruptions in the financial markets, interest rate fluctuations, decisions by the Idaho or Oregon public utility commissions, and the companies' past or projected financial performance;

•ability to enter into financial and physical commodity hedges with creditworthy counterparties to manage price and commodity risk for fuel, power, and transmission, and the failure of any such risk management and hedging strategies to work as intended, and the potential losses the companies may incur on those hedges, which can be affected by factors such as the volume of hedging transactions and degree of price volatility;

•changes in actuarial assumptions, changes in interest rates, increasing health care costs, and the actual and projected return on plan assets for pension and other post-retirement plans, which can affect future pension and other postretirement plan funding obligations, costs, and liabilities and the companies' cash flows;

•remediation costs associated with planned exits from participation in Idaho Power's co-owned coal plants;

•ability to continue to pay dividends and achieve target dividend payout ratios based on financial performance, capital requirements, and in light of credit rating considerations, contractual covenants and restrictions, and regulatory limitations; and

•adoption of or changes in accounting policies and principles, changes in accounting estimates, and new SEC or New York Stock Exchange requirements or new interpretations of existing requirements.

Any forward-looking statement speaks only as of the date on which such statement is made. New factors emerge from time to time and it is not possible for management to predict all such factors, nor can it assess the impact of any such factor on the business or the extent to which any factor, or combination of factors, may cause results to differ materially from those contained in any forward-looking statement. IDACORP and Idaho Power disclaim any obligation to update publicly any forward-looking information, whether in response to new information, future events, or otherwise, except as required by applicable law.

IDACORP, INC. AND IDAHO POWER COMPANY

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(unaudited)

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

This Quarterly Report on Form 10-Q is a combined report of IDACORP, Inc. (IDACORP) and Idaho Power Company (Idaho Power). Therefore, these Notes to the Condensed Consolidated Financial Statements apply to both IDACORP and Idaho Power. However, Idaho Power makes no representation as to the information relating to IDACORP’s other operations.

Nature of Business

IDACORP is a holding company formed in 1998 whose principal operating subsidiary is Idaho Power. Idaho Power is an electric utility engaged in the generation, transmission, distribution, sale, and purchase of electric energy and capacity with a service area covering approximately 24,000 square miles in southern Idaho and eastern Oregon. Idaho Power is regulated primarily by the state utility regulatory commissions of Idaho and Oregon and the Federal Energy Regulatory Commission. Idaho Power is the parent of Idaho Energy Resources Co. (IERCo), a joint venturer in Bridger Coal Company (BCC), which mines and supplies coal to the Jim Bridger power plant (Jim Bridger plant) owned in part by Idaho Power.

IDACORP’s other notable wholly-owned subsidiaries include IDACORP Financial Services, Inc. (IFS), an investor in affordable housing and other real estate tax credit investments, and Ida-West Energy Company (Ida-West), an operator of small hydropower generation projects that satisfy the requirements of the Public Utility Regulatory Policies Act of 1978 (PURPA).

Regulation of Utility Operations

As a regulated utility, many of Idaho Power's fundamental business decisions are subject to the approval of governmental agencies, including the prices that Idaho Power is authorized to charge for its electric service. These approvals are a critical factor in determining IDACORP's and Idaho Power's results of operations and financial condition.

IDACORP's and Idaho Power's financial statements reflect the effects of the different ratemaking principles followed by the jurisdictions regulating Idaho Power. The application of accounting principles related to regulated operations sometimes results in Idaho Power recording expenses and revenues in a different period than when an unregulated enterprise would record such expenses and revenues. In these instances, the amounts are deferred or accrued as regulatory assets or regulatory liabilities on the balance sheet. Regulatory assets represent incurred costs that have been deferred because it is probable they will be recovered from customers through future rates. Regulatory liabilities represent obligations to make refunds to customers for previous collections, or represent amounts collected in advance of incurring an expense. The effects of applying these regulatory accounting principles to Idaho Power's operations are discussed in more detail in Note 3 - "Regulatory Matters."

Financial Statements

In the opinion of management of IDACORP and Idaho Power, the accompanying unaudited condensed consolidated financial statements contain all adjustments necessary to present fairly each company's condensed consolidated balance sheets as of June 30, 2023, condensed consolidated statements of income for the three months and six months ended June 30, 2023 and 2022, and condensed consolidated cash flows for the six months ended June 30, 2023 and 2022. These adjustments are of a normal and recurring nature. These financial statements do not contain the complete detail or note disclosures concerning accounting policies and other matters that would be included in full-year financial statements and should be read in conjunction with the audited consolidated financial statements included in IDACORP’s and Idaho Power’s Annual Report on Form 10-K for the year ended December 31, 2022 (2022 Annual Report). The statements of income for the interim period are not necessarily indicative of the results to be expected for the full year. A change in management's estimates or assumptions could have a material impact on IDACORP's or Idaho Power's respective balance sheets and statements of income during the period in which such change occurred.

Management Estimates

Management makes estimates and assumptions when preparing financial statements in conformity with accounting principles generally accepted in the United States of America (GAAP). These estimates and assumptions include, among others, those related to rate regulation, retirement benefits, contingencies, asset impairment, income taxes, unbilled revenues, and bad debt. These estimates and assumptions affect the reported amounts of assets and liabilities and the disclosure of contingent assets and

Table of Contents

liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. These estimates involve judgments with respect to, among other things, future economic factors that are difficult to predict and are beyond management's control. Accordingly, actual results could differ from those estimates.

New and Recently Adopted Accounting Pronouncements

There have been no recently issued accounting pronouncements that have had or are expected to have a material impact on IDACORP's or Idaho Power's condensed consolidated financial statements.

2. INCOME TAXES

In accordance with interim reporting requirements, IDACORP and Idaho Power use an estimated annual effective tax rate for computing their provisions for income taxes. An estimate of annual income tax expense (or benefit) is made each interim period using estimates for annual pre-tax income, income tax adjustments, and tax credits. The estimated annual effective tax rates do not include discrete events such as tax law changes, examination settlements, accounting method changes, or adjustments to tax expense or benefits attributable to prior years. Discrete events are recorded in the interim period in which they occur or become known. The estimated annual effective tax rate is applied to year-to-date pre-tax income to determine income tax expense (or benefit) for the interim period consistent with the annual estimate. In subsequent interim periods, income tax expense (or benefit) for the period is computed as the difference between the year-to-date amount reported for the previous interim period and the current period's year-to-date amount.

Income Tax Expense

The following table provides a summary of income tax expense for the six months ended June 30, 2023 and 2022 (in thousands):

3. REGULATORY MATTERS

Included below is a summary of Idaho Power's most recent general rate cases and base rate changes, as well as other recent or pending notable regulatory matters and proceedings.

Idaho and Oregon General Rate Cases

Idaho Power's current base rates result from the Idaho Public Utilities Commission (IPUC) and Public Utility Commission of Oregon (OPUC) orders described in Note 3 - "Regulatory Matters" to the consolidated financial statements included in the 2022 Annual Report.

On June 1, 2023, Idaho Power filed a general rate case with the IPUC. The filing is based on a 2023 test year and requests approximately $111 million in additional Idaho jurisdiction annual revenues, which is net of a corresponding proposed power cost adjustment (PCA) decrease of $173.4 million and a reduction to annual energy efficiency rider collection of $3.5 million. If approved, this request would result in an 8.61 percent overall average net base rate increase for Idaho Power's Idaho customers. The filing requests, among other items, a 10.4 percent authorized rate of return on equity and an approximate $3.9 billion Idaho retail rate base. The $3.9 billion of rate base excludes rate base associated with Idaho Power's jointly-owned coal facilities, the costs of which are recovered under separate rate mechanisms. In its application, Idaho Power proposed a capitalization structure of 49 percent long-term debt and 51 percent common stock equity. Idaho Power included an average cost of debt of 4.895 percent, and an overall cost of capital of 7.702 percent.

Table of Contents

In addition, Idaho Power's filing requests approval or authorization of, among other items:

•Modifications to the Idaho-jurisdiction power cost adjustment (PCA) necessary to support the transfer of certain base level net power supply costs from the PCA to base rates;

•Modifications to the energy efficiency rider to support the transfer of energy efficiency labor-related cost collection from the annual energy efficiency rider into base rates;

•Modifications to the fixed cost adjustment (FCA) mechanism to support Idaho Power's proposed rate designs;

•Continued deferral of incremental vegetation management and insurance costs in 2024 and beyond as measured from a new base level of costs established in the general rate case;

•An annual $18 million increase in collection of Idaho Power’s regulatory asset associated with its defined benefit pension plan contributions;

•A rate increase mitigation measure, in lieu of increasing base rates, to (1) move an estimated $45 million of investment tax credits, including from certain battery storage projects, to the existing ADITC and revenue sharing mechanism described in more detail below, and (2) increase the existing $25 million maximum allowed annual additional accelerated ADITC amortization amount under the mechanism by a dollar amount of investment tax credits equal to the actual revenue requirement of those battery storage projects in any applicable year;

•Deferral and amortization of annual differences between certain periodic maintenance costs at Idaho Power's natural gas-fired power plants; and

•A proposed residential price modernization plan.

As of the date of this report, Idaho Power is unable to predict the outcome of the general rate case. Idaho Power anticipates that new rates, if approved by the IPUC, would become effective on or after January 1, 2024.

Idaho Settlement Stipulations

A May 2018 Idaho settlement stipulation related to tax reform (May 2018 Idaho Tax Reform Settlement Stipulation) is described in Note 3 - "Regulatory Matters" to the consolidated financial statements included in the 2022 Annual Report and includes provisions for the accelerated amortization of ADITC to help achieve a minimum 9.4 percent Idaho-jurisdiction return on year-end equity (Idaho ROE). In addition, under the May 2018 Idaho Tax Reform Settlement Stipulation, the Idaho ROE at which Idaho Power would begin amortizing additional ADITC would revert back to 95 percent of the authorized return on equity in the next general rate case. The settlement stipulation also provides for the potential sharing between Idaho Power and Idaho customers of Idaho-jurisdictional earnings in excess of a 10.0 percent Idaho ROE, which would adjust to the authorized return on equity in the next general rate case currently pending before the IPUC.

Based on its estimate of full-year 2023 Idaho ROE, in the three and six months ended June 30, 2023, Idaho Power recorded $3.8 million and $7.5 million, respectively, for additional ADITC amortization under the May 2018 Idaho Tax Reform Settlement Stipulation. The additional ADITC amortization was recorded in income tax expense on Idaho Power's condensed consolidated statements of income. Accordingly, at June 30, 2023, $37.5 million of additional ADITC remains available for future use. Idaho Power recorded no additional ADITC amortization or provision against revenues for sharing of earnings with customers during 2022.

Power Cost Adjustment Mechanisms

In both its Idaho and Oregon jurisdictions, Idaho Power's power cost adjustment mechanisms address the volatility of power supply costs and provide for annual adjustments to the rates charged to its retail customers. The power cost adjustment mechanisms compare Idaho Power's actual net power supply costs (primarily fuel and purchased power less wholesale energy sales) against net power supply costs being recovered in Idaho Power's retail rates. Under the power cost adjustment mechanisms, certain differences between actual net power supply costs incurred by Idaho Power and costs being recovered in retail rates are recorded as a deferred charge or credit on the balance sheet for future recovery or refund. The power supply costs deferred primarily result from changes in contracted power purchase prices and volumes, changes in wholesale market prices and transaction volumes, fuel prices, and the levels of Idaho Power's own generation.

In May 2023, the IPUC issued an order approving recovery of an incremental $200.2 million of Idaho-jurisdiction PCA revenues, which included an increase in the forecasted power supply cost component and the deferral balance component. The IPUC directed Idaho Power to spread recovery of the $190.2 million deferral balance component of the PCA over a two-year period from June 1, 2023, to May 31, 2025, resulting in a total PCA increase of $105.1 million, effective for the PCA collection period from June 1, 2023, to May 31, 2024. The order defers collection of $95.1 million of deferred PCA costs to the subsequent annual PCA collection period from June 1, 2024, to May 31, 2025. The net increase in PCA revenues reflects higher market energy and natural gas prices, combined with lower-than-expected hydropower generation and limited coal supply in the

Table of Contents

prior April 2022 to March 2023 PCA period. The net increase also reflects an expectation of continued elevated market energy and natural gas prices in the April 2023 to March 2024 forecast period under the PCA.

In May 2023, the OPUC issued an order approving Idaho Power's annual power cost update settlement, for a $7.7 million increase in Oregon-jurisdiction rates effective June 1, 2023.

Idaho Fixed Cost Adjustment Mechanism

The Idaho-jurisdiction FCA mechanism, applicable to Idaho residential and small commercial customers, is designed to remove a portion of Idaho Power’s financial disincentive to invest in energy efficiency programs by separating (or decoupling) the recovery of fixed costs from the variable kilowatt-hour (kWh) charge and linking it instead to a set amount per customer. Under Idaho Power's current rate design, Idaho Power recovers a portion of fixed costs through the variable kWh charge, which may result in over-collection or under-collection of fixed costs. To return over-collection to customers or to collect under-collection from customers, the FCA mechanism allows Idaho Power to accrue, or defer, the difference between the authorized fixed-cost recovery amount per customer and the actual fixed costs per customer recovered by Idaho Power during the year. The IPUC has discretion to cap the annual increase in the FCA recovery at 3 percent of base revenue, with any excess deferred for collection in a subsequent year. In May 2023, the IPUC issued an order approving a $10.1 million decrease in recovery from the FCA from $35.2 million to $25.1 million for the 2022 FCA deferral, with new rates effective for the period from June 1, 2023, to May 31, 2024.

Jim Bridger Power Plant Rate Base Adjustment and Recovery

In June 2022, the IPUC issued an order approving, with modifications, Idaho Power’s amended application requesting authorization to (1) accelerate depreciation for the Jim Bridger plant to allow the coal-related plant assets to be fully depreciated and recovered by December 31, 2030, (2) establish a balancing account to track the incremental costs, benefits, and required regulatory accounting associated with ceasing participation in coal-fired operations at the Jim Bridger plant, and (3) increase customer rates related to the associated incremental annual levelized revenue requirement (Bridger Order).

The Bridger Order allows for regulatory accounting entries and establishes balancing accounts (recorded as regulatory assets or liabilities on Idaho Power’s and IDACORP’s consolidated balance sheets) to track differences between amounts recovered in rates and actual incremental costs and benefits associated with Idaho Power’s cessation of coal-fired operations at the Jim Bridger plant. The incremental costs and benefits include the revenue requirement associated with the incremental Jim Bridger plant coal-related investments made from 2012 through the end of 2020, forecasted coal-related investments, and near-term decommissioning costs, offset by other operations and maintenance (O&M) cost savings. The Bridger Order deemed all coal-related investments at the Jim Bridger plant from 2012 through 2020 to be prudent for recovery. In the Bridger Order, the IPUC reduced Idaho Power's requested rate increase from 2.1 percent in its amended filing to 1.5 percent, a reduction from a requested $27.1 million to $18.8 million annually. The Bridger Order provides that any uncollected amount resulting from the reduction in the rate increase will be recorded in the balancing account for future recovery with no carrying charge. Uncollected amounts tracked in this balancing account were included for recovery in Idaho Power's June 1, 2023, general rate case filing with the IPUC. Idaho Power anticipates making future filings with the IPUC that may result in periodic adjustments to rates to true up variances between revenue collections and actual revenue requirement amounts. The Bridger Order allows Idaho Power to earn a return on and recover through 2030 the net book value of coal-related assets at the Jim Bridger plant as of December 31, 2020, as well as forecasted coal-related investments.

Wildfire Mitigation Cost Recovery

In June 2021, the IPUC authorized Idaho Power to defer for future amortization incremental O&M and depreciation expense for certain capital investments necessary to implement Idaho Power's Wildfire Mitigation Plan (WMP). The IPUC also authorized Idaho Power to record these deferred expenses as a regulatory asset until Idaho Power can request amortization of the deferred costs in a future IPUC proceeding, at which time the IPUC will have the opportunity to review actual costs and determine the amount of prudently incurred costs that Idaho Power can recover through retail rates. In its 2021 application with the IPUC, Idaho Power projected spending approximately $47 million in incremental wildfire mitigation-related O&M and roughly $35 million in wildfire mitigation system-hardening incremental capital expenditures over a five-year period. The IPUC authorized a deferral period of five years, or until rates go into effect from Idaho Power's next general rate case, whichever is first. As of June 30, 2023, Idaho Power's deferral of Idaho-jurisdiction costs related to the WMP was $39.5 million.

Table of Contents

updated WMP with the IPUC along with an application requesting authorization to defer an estimated $16 million of newly identified incremental costs expected to be incurred between 2022 and 2025 associated with expanded wildfire mitigation efforts. In March 2023, the IPUC approved Idaho Power's updated WMP and request to defer the additional incremental costs.

Total revenues from contracts with customers	$	385,229	$	345,483	$	770,895	$	663,665

(1) The FCA mechanism is an alternative revenue program in the Idaho jurisdiction and does not represent revenue from contracts with customers.

(2) The IPUC allows Idaho Power to recover a portion of the allowance for funds used during construction (AFUDC) on construction work in progress related to the Hells Canyon Complex (HCC) relicensing process, even though the relicensing process is not yet complete and the costs have not been moved to electric plant in service. Idaho Power is collecting $8.8 million annually in the Idaho jurisdiction but is deferring revenue recognition of the amounts collected until the license is issued and the accumulated license costs approved for recovery are placed in service.

Alternative Revenue Programs and Other Revenues

While revenues from contracts with customers make up most of Idaho Power’s revenues, the IPUC has authorized the use of an additional regulatory mechanism, the Idaho FCA mechanism, which may increase or decrease tariff-based customer rates. The Idaho FCA mechanism is described in Note 3 - "Regulatory Matters." The FCA mechanism revenues include only the initial recognition of FCA revenues when they meet the regulator-specified conditions for recognition. Revenue from contracts with customers excludes the portion of the tariff price representing FCA revenues that Idaho Power initially recorded in prior periods when revenues met regulator-specified conditions. When Idaho Power includes those amounts in the price of utility service and billed to customers, Idaho Power records such amounts as recovery of the associated regulatory asset or liability and not as revenues.

Table of Contents

Derivative revenues include gains from settled electricity swaps and sales of electricity under forward sales contracts that are bundled with renewable energy credits. Related to these forward sales, Idaho Power simultaneously enters into forward purchases of electricity for the same quantity at the same location, which are recorded in purchased power on the condensed consolidated statements of income. For more information on settled electricity swaps, see Note 11 - "Derivative Financial Instruments."

The table below presents the FCA mechanism revenues and other revenues for the three months and six months ended June 30, 2023 and 2022 (in thousands):

5. LONG-TERM DEBT

Long-Term Debt Issuances and Redemptions

On December 22, 2022, Idaho Power entered into a Bond Purchase Agreement with certain institutional purchasers relating to the sale by Idaho Power of $170 million of first mortgage bonds, secured medium-term notes, Series N (Series N Notes), as described in Note 5 - "Long-Term Debt" to the consolidated financial statements included in the 2022 Annual Report. On March 8, 2023, Idaho Power issued $60 million in aggregate principal amount of 5.06% first mortgage bonds, secured medium-term notes, Series N, maturing on March 8, 2043; and $62 million in aggregate principal amount of 5.20% first mortgage bonds, secured medium-term notes, Series N, maturing on March 8, 2053.

Idaho Power also issues secured medium term notes from time to time under a shelf registration statement with the SEC, as described in Note 5 - "Long-Term Debt" to the consolidated financial statements included in the 2022 Annual Report. On March 14, 2023, under the shelf registration statement with the SEC, Idaho Power issued $400 million in aggregate principal amount of 5.50% first mortgage bonds, secured medium-term notes, Series M, maturing on March 15, 2053. On April 1, 2023, Idaho Power repaid $75 million in aggregate principal amount of maturing 2.50% first mortgage bonds due 2023, Series I.

On March 4, 2022, Idaho Power entered into a floating rate term loan credit agreement (Term Loan Facility) for the issuance of up to an aggregate principal amount of $150 million due 2024, bearing interest at floating rates based on the Secured Overnight Financing Rate (SOFR), as described in Note 5 - "Long-Term Debt" to the consolidated financial statements included in the 2022 Annual Report. On March 31 and May 17, 2023, Idaho Power repaid $100 million and $50 million of the Term Loan Facility, respectively. As of June 30, 2023, there was no remaining outstanding principal balance of the Term Loan Facility.

6. COMMON STOCK

IDACORP Common Stock

During the six months ended June 30, 2023, IDACORP granted 75,295 restricted stock unit awards to employees and issued 52,897 shares of common stock using original issuances of shares pursuant to the IDACORP, Inc. 2000 Long-Term Incentive and Compensation Plan, including 13,842 shares of common stock issued to members of the board of directors. As directed by IDACORP, plan administrators of the IDACORP, Inc. Dividend Reinvestment and Stock Purchase Plan and Idaho Power Company Employee Savings Plan used market purchases of IDACORP common stock to acquire shares of IDACORP common stock for the plans.

Restrictions on Dividends

Idaho Power’s ability to pay dividends on its common stock held by IDACORP and IDACORP’s ability to pay dividends on its common stock are limited to the extent payment of such dividends would violate the covenants in their respective Credit Facilities or Idaho Power’s Revised Code of Conduct. A covenant under IDACORP’s credit facility and Idaho Power’s credit facility requires IDACORP and Idaho Power to maintain leverage ratios of consolidated indebtedness to consolidated total capitalization, as defined therein, of no more than 65 percent at the end of each fiscal quarter. At June 30, 2023, the leverage ratios for IDACORP and Idaho Power were 47 percent and 48 percent, respectively. Based on these restrictions, IDACORP’s and Idaho Power’s dividends were limited to $1.5 billion and $1.4 billion, respectively, at June 30, 2023. There are additional facility covenants, subject to exceptions, that prohibit or restrict the sale or disposition of property without consent and any agreements restricting dividend payments to IDACORP and Idaho Power from any material subsidiary. At June 30, 2023, IDACORP and Idaho Power were in compliance with those covenants.

Idaho Power’s Revised Policy and Code of Conduct relating to transactions between and among Idaho Power, IDACORP, and other affiliates, which was approved by the IPUC in April 2008, provides that Idaho Power will not pay any dividends to IDACORP that will reduce Idaho Power’s common equity capital below 35 percent of its total adjusted capital without IPUC approval. At June 30, 2023, Idaho Power's common equity capital was 52 percent of its total adjusted capital. Further, Idaho Power must obtain approval from the OPUC before it can directly or indirectly loan funds or issue notes or give credit on its books to IDACORP.

Idaho Power’s articles of incorporation contain restrictions on the payment of dividends on its common stock if preferred stock dividends are in arrears. As of the date of this report, Idaho Power has no preferred stock outstanding.

In addition to contractual restrictions on the amount and payment of dividends, the Federal Power Act prohibits the payment of dividends from "capital accounts." The term "capital account" is undefined in the Federal Power Act or its regulations, but Idaho Power does not believe the restriction would limit Idaho Power's ability to pay dividends out of current year earnings or retained earnings.

7. EARNINGS PER SHARE

8. COMMITMENTS

Purchase Obligations

During the six months ended June 30, 2023, Idaho Power entered into:

•an agreement in April 2023 to utilize the storage capacity of a 150-megawatt (MW) battery storage facility, subject to regulatory approval, which increased Idaho Power's contractual purchase obligations by approximately $430.9 million over the 20-year term of the contract. The facility is scheduled to be online in June 2025;

•an agreement in May 2023 to replace an expiring PURPA-qualifying hydropower facility power purchase agreement, which increased Idaho Power's contractual purchase obligations by approximately $29.1 million over the 20-year term of the contract;

•an agreement in June 2023 to utilize up to one billion cubic feet of natural gas storage capacity, starting in April 2025, which increased Idaho Power's contractual purchase obligations by approximately $24.4 million over the 10-year term of the contract; and

•an agreement in June 2023 to acquire and own 36 MW of battery storage assets, which increased Idaho Power's contractual purchase obligations by approximately $52.6 million over the 1-year term of the contract. The batteries are scheduled to be online in the spring of 2024. During the six months ended June 30, 2023, Idaho Power made payments of $10.5 million related to this obligation.

In July 2023, Idaho Power entered into an agreement to meet certain environmental mitigation requirements in the State of Oregon for the Boardman-to-Hemingway transmission line project, which increased Idaho Power's contractual obligations by $16.9 million over the approximate 1-year term of the contract.

In July 2023, IFS committed to invest $35 million in an affordable housing tax credit project over an 18-year term.

Except as disclosed in this Note 8, during the six months ended June 30, 2023, IDACORP's and Idaho Power's contractual obligations, outside the ordinary course of business, did not change materially from the amounts disclosed in the notes to the consolidated financial statements in the 2022 Annual Report.

Acquisition of Additional Interest in Boardman-To-Hemingway Transmission Project

In March 2023, Idaho Power executed a purchase, sale, and security agreement with the Bonneville Power Administration (BPA) to transfer BPA's 24 percent interest in the Boardman-to-Hemingway transmission line project to Idaho Power, bringing Idaho Power's interest in the project to 45 percent. Pursuant to the agreement, Idaho Power has a commitment to provide long-term transmission service to BPA. The agreement also required BPA to make a $10 million security payment to Idaho Power. On Idaho Power's condensed consolidated balance sheet, the agreement increased construction work in progress by $31.4 million for the acquired permitting interest, cash and cash equivalents by $10.0 million for the additional security payment, and other non-current liabilities by $41.4 million for Idaho Power's obligation to pay for the permitting interest and to return the security deposit to BPA. Payments to BPA for the permitting interest are expected to be made over a 15-year period beginning 10 years after energization of the transmission line project, while the security deposit is due to be returned to BPA upon energization.

Guarantees

Idaho Power guarantees its portion of reclamation activities and obligations at BCC, of which IERCo owns a one-third interest. This guarantee, which is renewed annually with the Wyoming Department of Environmental Quality, was $47.3 million at June 30, 2023, representing IERCo's one-third share of BCC's total reclamation obligation of $141.9 million. BCC has a reclamation trust fund set aside specifically for the purpose of paying these reclamation costs. At June 30, 2023, the value of BCC's reclamation trust fund was $226.2 million. During the six months ended June 30, 2023, the reclamation trust fund made $2.2 million of distributions for reclamation activity costs associated with the BCC surface mine. BCC periodically assesses the adequacy of the reclamation trust fund and its estimate of future reclamation costs. To ensure that the reclamation trust fund maintains adequate reserves, BCC has the ability to, and does, add a per-ton surcharge to coal sales, all of which are made to the Jim Bridger plant. Because of the existence of the fund and the ability to apply a per-ton surcharge, the estimated fair value of this guarantee is minimal.

IDACORP and Idaho Power enter into financial agreements and power purchase and sale agreements that include indemnification provisions relating to various forms of claims or liabilities that may arise from the transactions contemplated by these agreements. Generally, a maximum obligation is not explicitly stated in the indemnification provisions and, therefore, the

Table of Contents

overall maximum amount of the obligation under such indemnification provisions cannot be reasonably estimated. IDACORP and Idaho Power periodically evaluate the likelihood of incurring costs under such indemnities based on their historical experience and the evaluation of the specific indemnities. As of June 30, 2023, management believe the likelihood is remote that IDACORP or Idaho Power would be required to perform under such indemnification provisions or otherwise incur any significant losses with respect to such indemnification obligations. Neither IDACORP nor Idaho Power has recorded any liability on their respective condensed consolidated balance sheets with respect to these indemnification obligations.

9. CONTINGENCIES

IDACORP and Idaho Power have in the past and expect in the future to become involved in various claims, controversies, disputes, and other contingent matters, some of which involve litigation and regulatory or other contested proceedings. The ultimate resolution and outcome of litigation and regulatory proceedings is inherently difficult to determine, particularly where (a) the remedies or penalties sought are indeterminate, (b) the proceedings are in the early stages or the substantive issues have not been well developed, or (c) the matters involve complex or novel legal theories or a large number of parties. In accordance with applicable accounting guidance, IDACORP and Idaho Power, as applicable, establish an accrual for legal proceedings when those matters proceed to a stage where they present loss contingencies that are both probable and reasonably estimable. If the loss contingency at issue is not both probable and reasonably estimable, IDACORP and Idaho Power do not establish an accrual and the matter will continue to be monitored for any developments that would make the loss contingency both probable and reasonably estimable. As of the date of this report, IDACORP's and Idaho Power's accruals for loss contingencies are not material to their financial statements as a whole; however, future accruals could be material in a given period. IDACORP's and Idaho Power's determination is based on currently available information, and estimates presented in financial statements and other financial disclosures involve significant judgment and may be subject to significant uncertainty. For matters that affect Idaho Power's operations, Idaho Power intends to seek, to the extent permissible and appropriate, recovery through the ratemaking process of costs incurred, although there is no assurance that such recovery would be granted.

IDACORP and Idaho Power are parties to legal claims and legal, tax, and regulatory actions and proceedings in the ordinary course of business and, as noted above, record an accrual for associated loss contingencies when they are probable and reasonably estimable. In connection with its utility operations, Idaho Power is subject to claims by individuals, entities, and governmental agencies for damages for alleged personal injury, property damage, and economic losses, relating to the company’s provision of electric service and the operation of its generation, transmission, and distribution facilities. Some of those claims relate to electrical contacts, service quality, property damage, and wildfires. In recent years, utilities in the western United States have been subject to significant liability for personal injury, loss of life, property damage, trespass, and economic losses, and in some cases, punitive damages and criminal charges, associated with wildfires that originated from utility property, most commonly transmission and distribution lines. Idaho Power has also regularly received claims by governmental agencies and private landowners for damages for fires allegedly originating from Idaho Power’s transmission and distribution system. As of the date of this report, the companies believe that resolution of existing claims will not have a material adverse effect on their respective condensed consolidated financial statements.

Idaho Power is also actively monitoring various pending environmental regulations and executive orders related to environmental matters that may have a significant impact on its future operations. Given uncertainties regarding the outcome, timing, and compliance plans for these environmental matters, Idaho Power is unable to estimate the financial impact of these regulations.

10. BENEFIT PLANS

Idaho Power has a noncontributory defined benefit pension plan (pension plan) and two nonqualified defined benefit plans for certain senior management employees called the Security Plan for Senior Management Employees I and Security Plan for Senior Management Employees II (together, SMSP). Idaho Power also has a nonqualified defined benefit pension plan for directors that was frozen in 2002. Remaining vested benefits from that plan are included with the SMSP in the disclosures below. The benefits under the pension plan are based on years of service and the employee’s final average earnings. Idaho Power also maintains a defined benefit postretirement benefit plan (consisting of health care and death benefits) that covers all employees who were enrolled in the active-employee group plan at the time of retirement as well as their spouses and

Table of Contents

qualifying dependents. The table below shows the components of net periodic benefit costs for the pension, SMSP, and postretirement benefits plans for the three months ended June 30, 2023 and 2022 (in thousands).


	Pension Plan				SMSP				Postretirement Benefits				Total

(1) Net periodic benefit costs for the pension plan are recognized for financial reporting based upon the authorization of each regulatory jurisdiction in which Idaho Power operates. Under IPUC order, the Idaho portion of net periodic benefit cost is recorded as a regulatory asset and is recognized in the income statement as those costs are recovered through rates.

(2) Of total net periodic benefit cost recognized for financial reporting, $5.1 million and $5.0 million, respectively, were recognized in "Other operations and maintenance" and $1.6 million and $2.2 million, respectively, were recognized in "Other income, net" on the condensed consolidated statements of income of the companies for the three months ended June 30, 2023 and 2022.



The table below shows the components of net periodic benefit costs for the pension, SMSP, and postretirement benefits plans for the six months ended June 30, 2023 and 2022 (in thousands).
	Pension Plan				SMSP				Postretirement Benefits				Total

(2) Of total net periodic benefit cost recognized for financial reporting, $10.4 million and $9.9 million, respectively, were recognized in "Other operations and maintenance" and $3.2 million and $4.6 million, respectively, were recognized in "Other income, net" on the condensed consolidated statements of income of the companies for the six months ended June 30, 2023 and 2022.

Idaho Power has no minimum contribution requirement to its defined benefit pension plan in 2023, and during the six months ended June 30, 2023, Idaho Power made a $10 million contribution. Idaho Power is considering contributing up to an additional $30 million to its defined benefit pension plan during 2023 in a continued effort to balance the regulatory collection of these expenditures with the amount and timing of contributions, as well as to mitigate the cost of being in an underfunded position. The primary impact of pension contributions is on the timing of cash flows, as the timing of cost recovery lags behind contributions.

Idaho Power also has an Employee Savings Plan that complies with Section 401(k) of the Internal Revenue Code and covers substantially all employees. Idaho Power matches specified percentages of employee contributions to the Employee Savings Plan.

11. DERIVATIVE FINANCIAL INSTRUMENTS

Commodity Price Risk

Idaho Power is exposed to market risk relating to electricity, natural gas, and other fuel commodity prices, all of which are heavily influenced by supply and demand. Market risk may be influenced by market participants’ nonperformance of their contractual obligations and commitments, which affects the supply of or demand for the commodity. Idaho Power uses derivative instruments, such as physical and financial forward contracts, for both electricity and fuel to manage the risks relating to these commodity price exposures. The primary objectives of Idaho Power’s energy purchase and sale activity are to meet the demand of retail electric customers, maintain appropriate physical reserves to ensure reliability, and make economic use of temporary surpluses that may develop.

All of Idaho Power's derivative instruments have been entered into for the purpose of securing energy resources for future periods or economically hedging forecasted purchases and sales, though none of these instruments have been designated as cash flow hedges. Idaho Power offsets fair value amounts recognized on its balance sheet and applies collateral related to derivative instruments executed with the same counterparty under the same master netting agreement. Idaho Power does not offset a counterparty's current derivative contracts with the counterparty's long-term derivative contracts, although Idaho Power's master netting arrangements would allow current and long-term positions to be offset in the event of default. Also, in the event of default, Idaho Power's master netting arrangements would allow for the offsetting of all transactions executed under the master netting arrangement. These types of transactions may include non-derivative instruments, derivatives qualifying for scope exceptions, receivables and payables arising from settled positions, and other forms of non-cash collateral (such as letters of credit). These types of transactions are excluded from the offsetting presented in the derivative fair value and offsetting table that follows.

The table below presents the gains and losses on derivatives not designated as hedging instruments for the three months and six months ended June 30, 2023 and 2022 (in thousands of dollars):

Settlement gains and losses on electricity swap contracts are recorded on the income statement in operating revenues or purchased power depending on the forecasted position being economically hedged by the derivative contract. Settlement gains and losses on contracts for natural gas are reflected in fuel expense. Settlement gains and losses on diesel derivatives are recorded in other O&M expense. See Note 12 - "Fair Value Measurements" for additional information concerning the determination of fair value for Idaho Power’s assets and liabilities from price risk management activities.

Credit Risk

At June 30, 2023, Idaho Power did not have material credit risk exposure from financial instruments, including derivatives. Idaho Power monitors credit risk exposure through reviews of counterparty credit quality, corporate-wide counterparty credit exposure, and corporate-wide counterparty concentration levels. Idaho Power manages these risks by establishing credit and concentration limits on transactions with counterparties and requiring contractual guarantees, cash deposits, or letters of credit from counterparties or their affiliates, as deemed necessary. Idaho Power’s physical power contracts are commonly under WSPP, Inc. agreements, physical gas contracts are usually under North American Energy Standards Board contracts, and financial transactions are usually under International Swaps and Derivatives Association, Inc. contracts. These contracts typically contain adequate assurance clauses requiring collateralization if a counterparty has debt that is downgraded below investment grade by at least one rating agency.

Table of Contents

Credit-Contingent Features

Certain of Idaho Power's derivative instruments contain provisions that require Idaho Power's unsecured debt to maintain an investment grade credit rating from Moody's and Standard & Poor's Ratings Services. If Idaho Power's unsecured debt were to fall below investment grade, it would be in violation of these provisions, and the counterparties to the derivative instruments could request immediate payment or demand immediate and ongoing full overnight collateralization on derivative instruments in net liability positions. The aggregate fair value of all derivative instruments with credit-risk-related contingent features that were in a liability position at June 30, 2023, was $33.7 million. Idaho Power posted $44.4 million of cash collateral related to its derivative instruments. If the credit-risk-related contingent features underlying these agreements were triggered on June 30, 2023, Idaho Power would have been required to pay or post collateral to its counterparties up to an additional $9.2 million to cover open liability positions as well as completed transactions that have not yet been paid.

12. FAIR VALUE MEASUREMENTS

IDACORP and Idaho Power have categorized their financial instruments into a three-level fair value hierarchy, based on the priority of the inputs to the valuation technique. The fair value hierarchy gives the highest priority to quoted prices in active markets for identical assets or liabilities (Level 1) and the lowest priority to unobservable inputs (Level 3). If the inputs used to measure the financial instruments fall within different levels of the hierarchy, the categorization is based on the lowest level input that is significant to the fair value measurement of the instrument.

Financial assets and liabilities recorded on the condensed consolidated balance sheets are categorized based on the inputs to the valuation techniques as follows:

• Level 1: Financial assets and liabilities whose values are based on unadjusted quoted prices for identical assets or liabilities in an active market that IDACORP and Idaho Power have the ability to access.

• Level 2: Financial assets and liabilities whose values are based on the following:

a) quoted prices for similar assets or liabilities in active markets;

b) quoted prices for identical or similar assets or liabilities in non-active markets;

c) pricing models whose inputs are observable for substantially the full term of the asset or liability; and

d) pricing models whose inputs are derived principally from or corroborated by observable market data through correlation or other means for substantially the full term of the asset or liability.

IDACORP and Idaho Power Level 2 inputs for derivative instruments are based on quoted market prices adjusted for location using corroborated, observable market data or using quoted price which may be in non-active markets.

• Level 3: Financial assets and liabilities whose values are based on prices or valuation techniques that require inputs that are both unobservable and significant to the overall fair value measurement. These inputs reflect management’s own assumptions about the assumptions a market participant would use in pricing the asset or liability.

IDACORP’s and Idaho Power’s assessment of a particular input's significance to the fair value measurement requires judgment and may affect the valuation of fair value assets and liabilities and their placement within the fair value hierarchy. There were no transfers between levels or material changes in valuation techniques or inputs during the six months ended June 30, 2023.

Certain instruments have been valued using net asset value (NAV) as a practical expedient. The NAV is generally not published and publicly available, nor are these instruments traded on an exchange. Instruments valued using NAV as a practical expedient are included in the fair value disclosures below; however, in accordance with GAAP are not classified within the fair value hierarchy levels.

(1) Holding company only. Does not include amounts held by Idaho Power.

Idaho Power’s derivatives are contracts entered into as part of its management of loads and resources. Electricity swap derivatives are valued on the Intercontinental Exchange (ICE) with quoted prices in an active market. Electricity forward contract derivatives are valued using a blend of two electricity exchanges, adjusted for location basis, as specified in the forward contract. Natural gas and diesel derivatives are valued using New York Mercantile Exchange (NYMEX) and ICE pricing, adjusted for location basis, which are also quoted under NYMEX and ICE pricing. Equity securities at Idaho Power consist of employee-directed investments related to an executive deferred compensation plan and actively traded money market and exchange traded funds related to the SMSP. The investments are measured using quoted prices in active markets and are held in a rabbi trust.

The table below presents the carrying value and estimated fair value of financial instruments that are not reported at fair value, as of June 30, 2023, and December 31, 2022, using available market information and appropriate valuation methodologies (in thousands of dollars).

using quoted rates for similar debt in active markets. Carrying values for cash and cash equivalents, deposits, customer and other receivables, notes payable, accounts payable, interest accrued, and taxes accrued approximate fair value.

13. SEGMENT INFORMATION

IDACORP’s only reportable segment is utility operations. The utility operations segment’s primary source of revenue is the regulated operations of Idaho Power. Idaho Power’s regulated operations include the generation, transmission, distribution, purchase, and sale of electricity. This segment also includes income from IERCo, a wholly-owned subsidiary of Idaho Power that is also subject to regulation and is a one-third owner of BCC, an unconsolidated joint venture.

IDACORP’s other operating segments are below the quantitative and qualitative thresholds for reportable segments and are included in the "All Other" category in the table below. This category is comprised of IFS’s investments in affordable housing and other real estate tax credit projects, Ida-West’s joint venture investments in small hydropower generation projects, and IDACORP’s holding company expenses.

The table below summarizes the segment information for IDACORP’s utility operations and the total of all other segments, and reconciles this information to total enterprise amounts (in thousands).

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the shareholders and the Board of Directors of IDACORP, Inc.

Results of Review of Interim Financial Information

We have reviewed the accompanying condensed consolidated balance sheet of IDACORP, Inc. and subsidiaries (the “Company”) as of June 30, 2023, the related condensed consolidated statements of income, comprehensive income, and equity for the three-month and six-month periods ended June 30, 2023 and 2022, and of cash flows for the six-month periods ended June 30, 2023 and 2022, and the related notes (collectively referred to as the "interim financial information"). Based on our reviews, we are not aware of any material modifications that should be made to the accompanying interim financial information for it to be in conformity with accounting principles generally accepted in the United States of America.

We have previously audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated balance sheet of the Company as of December 31, 2022, and the related consolidated statements of income, comprehensive income, equity, and cash flows for the year then ended (not presented herein); and in our report dated February 16, 2023, we expressed an unqualified opinion on those consolidated financial statements. In our opinion, the information set forth in the accompanying condensed consolidated balance sheet as of December 31, 2022, is fairly stated, in all material respects, in relation to the consolidated balance sheet from which it has been derived.

Basis for Review Results

This interim financial information is the responsibility of the Company’s management. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our reviews in accordance with standards of the PCAOB. A review of interim financial information consists principally of applying analytical procedures and making inquiries of persons responsible for financial and accounting matters. It is substantially less in scope than an audit conducted in accordance with the standards of the PCAOB, the objective of which is the expression of an opinion regarding the financial statements taken as a whole. Accordingly, we do not express such an opinion.

ITEM 2. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION

AND RESULTS OF OPERATIONS

In Management’s Discussion and Analysis of Financial Condition and Results of Operations (MD&A) in this report, the general financial condition and results of operations for IDACORP, Inc. and its subsidiaries (collectively, IDACORP) and Idaho Power Company and its subsidiary (collectively, Idaho Power) are discussed. While reading the MD&A, please refer to the accompanying condensed consolidated financial statements of IDACORP and Idaho Power. Also refer to "Cautionary Note Regarding Forward-Looking Statements" in this report for important information regarding forward-looking statements made in this MD&A and elsewhere in this report. This discussion updates the MD&A included in IDACORP's and Idaho Power's Annual Report on Form 10-K for the year ended December 31, 2022 (2022 Annual Report), and should also be read in conjunction with the information in that report. The results of operations for an interim period generally will not be indicative of results for the full year, particularly in light of the seasonality of Idaho Power's sales volumes, as discussed below.

INTRODUCTION

IDACORP is a holding company formed in 1998 whose principal operating subsidiary is Idaho Power. IDACORP’s common stock is listed and trades on the New York Stock Exchange under the trading symbol "IDA". Idaho Power is an electric utility whose rates and other matters are regulated by the Idaho Public Utilities Commission (IPUC), Public Utility Commission of Oregon (OPUC), and Federal Energy Regulatory Commission (FERC). Idaho Power generates revenues and cash flows primarily from the sale and distribution of electricity to customers in its Idaho and Oregon service areas, as well as from the wholesale sale and transmission of electricity. Idaho Power experiences its highest retail energy sales during the summer irrigation and cooling season, with a lower peak in the winter that generally results from heating demand.

Idaho Power is the parent of Idaho Energy Resources Co. (IERCo), a joint venturer in Bridger Coal Company (BCC), which mines and supplies coal to the Jim Bridger power plant (Jim Bridger plant) owned in part by Idaho Power. IDACORP’s other significant subsidiaries include IDACORP Financial Services, Inc., an investor in affordable housing and other real estate tax credit investments, and Ida-West Energy Company, an operator of small hydropower generation projects that satisfy the requirements of the Public Utility Regulatory Policies Act of 1978 (PURPA).

EXECUTIVE OVERVIEW

Management's Outlook and Company Objectives

In the 2022 Annual Report, IDACORP's and Idaho Power's management included a summary of their business objectives for the companies for 2023 and beyond, under the heading "Executive Overview" in the MD&A. As of the date of this report, management's outlook and strategy remain consistent with that discussion, as updated by some of the discussion in this MD&A. Developments that have occurred since that report include the following:

•Idaho Power continues to focus on timely recovery of costs and earning a reasonable return on investment. On June 1, 2023, Idaho Power filed a general rate case with the IPUC. The filing is described more fully in Note 3 - "Regulatory Matters" to the condensed consolidated financial statements included in this report.

•In March 2023, Idaho Power executed an agreement with the Bonneville Power Administration (BPA) to transfer BPA's 24 percent interest in the Boardman-to-Hemingway 500-kV transmission line project to Idaho Power, bringing Idaho Power's interest in the project to 45 percent. Further, in March 2023 the Oregon Supreme Court affirmed the Energy Facility Siting Council's (EFSC) order granting a site certificate for the Boardman-to-Hemingway transmission line project. In June 2023, both the IPUC and OPUC granted certificates of public convenience and necessity (CPCN) related to the construction of the Boardman-to-Hemingway transmission line.

•In April and May 2023, the IPUC approved Idaho Power's applications for revised special contracts for electric service between Idaho Power and two large industrial customers, which were modeled after Idaho Power's proposed Clean Energy Your Way program.

•In April 2023, the IPUC approved Idaho Power's 20-year power purchase agreement with Pleasant Valley Solar, LLC to purchase the output from a planned 200 megawatt (MW) solar facility, with a scheduled in-service date of March 2025. Idaho Power plans to sell that output exclusively to a large industrial customer under an agreement modeled after Idaho Power's proposed Clean Energy Your Way program.

•Also in April 2023, Idaho Power entered into a 20-year agreement to utilize the storage capacity from a 150-MW battery storage facility scheduled to be online in June 2025. Idaho Power intends for this capacity to supplement over 200 MW of company-owned storage that it expects to be online in 2023 and 2024, and an additional 77 MW of company-owned storage it anticipates adding in 2025, pending regulatory approval. In July 2023, 80 MW of company-owned battery storage came online.

Table of Contents

•Idaho Power issued a formal request for proposals (RFP) in April 2023, soliciting bids for new energy and capacity resources as well as energy that can be delivered via transmission, beginning in 2026. The company’s long-range planning process has identified a potential need in 2026 and 2027 of approximately 350 MW of peak capacity, which could be met by approximately 1,100 MW of variable energy resources. The RFP provides that a portion of these resources may be transmitted via the Boardman-to-Hemingway transmission line project, which Idaho Power plans to have in-service as early as 2026.

Net Income - Second Quarter 2023

IDACORP's net income increased $4.3 million for the second quarter of 2023 compared with the second quarter of 2022, due primarily to higher net income at Idaho Power. At Idaho Power, customer growth increased operating income by $4.1 million in the second quarter of 2023 compared with the second quarter of 2022, as the number of Idaho Power customers grew by approximately 13,100, or 2.1 percent, during the twelve months ended June 30, 2023. Usage per customer decreased operating income by $1.7 million in the second quarter of 2023 compared with the second quarter of 2022, due primarily to a 5 percent decrease in usage per industrial customer. In addition to slightly lower economic activity in a few industrial sectors, operation

of a customer-owned-and-operated co-generation facility reduced industrial customer energy usage during the second quarter of 2023 compared with the second quarter of 2022 when the co-generation facility was down for maintenance.

The net increase in retail revenues per MWh, net of associated power supply costs and power cost adjustment mechanisms, increased operating income by $2.4 million in the second quarter of 2023 compared with the second quarter of 2022. The net increase in retail revenues per MWh was primarily due to the June 1, 2022, rate increase for Idaho Power’s Idaho retail customers related to an order from the IPUC that authorized Idaho Power to accelerate the depreciation on and recover through 2030 the net book value of coal-related assets at Idaho Power's jointly-owned Jim Bridger plant as of December 31, 2020, plus forecasted plant investments. For more information on the IPUC regulatory order related to the Jim Bridger Plant (Bridger Order), see Note 3 - "Regulatory Matters" to the consolidated financial statements included in the 2022 Annual Report.

Total other O&M expenses in the second quarter of 2023 were $3.4 million lower than the second quarter of 2022, due primarily to lower expenses from scheduled cyclical plant maintenance projects compared with the same period in 2022, offset partially by inflationary pressures on labor-related and other costs.

Depreciation expense increased $12.3 million in the second quarter of 2023 compared with the second quarter of 2022 due primarily to the notable impact in the second quarter of 2022 of the Bridger Order. The Bridger Order resulted in Idaho Power recording the deferral of certain depreciation expense in the second quarter of 2022. In addition, the increase in the second quarter of 2023 compared with the second quarter of 2022 is also partially due to an increase in plant-in-service.

Other changes in operating revenues and expenses, net, increased operating income by $3.0 million in the second quarter of 2023 compared with the second quarter of 2022, due primarily to a decrease in net power supply expenses that were not deferred for future recovery in rates through Idaho Power's power cost adjustment mechanisms. Lower wholesale natural gas and power market prices in the western United States decreased Idaho Power's net power supply expenses in the second quarter of 2023 compared with the second quarter of 2022.

Non-operating expense, net, decreased $2.8 million in the second quarter of 2023 compared with the second quarter of 2022. Allowance for equity funds used during construction increased as the average construction work in progress balance was higher throughout the second quarter of 2023 compared with the second quarter of 2022. Also, interest income increased due to higher market interest rates. These increases were partially offset by higher interest expense on long-term debt in the second quarter of 2023 compared with the second quarter of 2022.

The decrease in income tax expense in the second quarter of 2023 compared with the second quarter of 2022 was principally the result of additional ADITC amortization, partially offset by higher pre-tax income. Based on Idaho Power's current expectations of full-year 2023 results, Idaho Power recorded $3.8 million of additional ADITC amortization under its Idaho regulatory settlement stipulation during the second quarter of 2023. Idaho Power currently expects to amortize up to $15 million of additional ADITC for the full-year 2023, but did not record any additional ADITC amortization in 2022.

Net Income - Year-To-Date 2023

IDACORP's net income increased $14.2 million for the first six months of 2023 compared with the first six months of 2022, due primarily to higher net income at Idaho Power. At Idaho Power, customer growth increased operating income by $6.8 million while usage per retail customer was relatively consistent in the first six months of 2023 compared with the first six months of 2022.

The net increase in retail revenues per MWh, net of associated power supply costs and power cost adjustment mechanisms, increased operating income by $10.8 million in the first six months of 2023 compared with the first six months of 2022. The net increase in retail revenues per MWh was primarily due to the June 1, 2022, rate increase for Idaho Power’s Idaho retail customers related to the Bridger Order.

Transmission wheeling-related revenues increased $6.8 million during the first six months of 2023 compared with the first six months of 2022, resulting from Idaho Power's Open Access Transmission Tariff (OATT) rates being 1 percent higher and due to elevated energy prices in the western United States in the first quarter of 2023 compared with the first quarter of 2022.

Total other O&M expenses in the first six months of 2023 were $3.5 million lower than the first six months of 2022, due primarily to lower expenses from scheduled cyclical plant maintenance projects compared with the same period in 2022, as well as the timing of regulatory deferrals and payment credits received related to a jointly-funded project. These decreases in other O&M expenses were offset partially by inflationary pressures on labor-related and other costs.

Table of Contents

Depreciation expense increased $13.2 million due primarily to the impacts of the Bridger Order. The Bridger Order resulted in Idaho Power recording the deferral of certain depreciation expense in the second quarter of 2022. In addition, the increase is also partially due to an increase in plant-in-service.

Other changes in operating revenues and expenses, net, decreased operating income by $4.0 million in the first six months of 2023 compared with the first six months of 2022, due primarily to the net increase in net power supply expenses that were not deferred for future recovery in rates through Idaho Power's power cost adjustment mechanisms. Compared with the same periods of 2022, the increase in Idaho Power's net power supply expenses due to higher wholesale natural gas and power market prices in the western United States in the first quarter of 2023 was partially offset by the decrease in Idaho Power's net power supply costs due to lower wholesale natural gas and power market prices in the western United States in the second quarter of 2023.

Non-operating expense, net, decreased $5.5 million in the first six months of 2023 compared with the first six months of 2022. Allowance for equity funds used during construction increased as the average construction work in progress balance was higher throughout the first six months of 2023 compared with the first six months of 2022. Also, interest income increased due to higher market interest rates. These increases were partially offset by higher interest expense on long-term debt in the first six months of 2023 compared with the first six months of 2022.

Income tax expense in the first six months of 2023 was consistent with the first six months of 2022 as increased taxes from higher pre-tax income was more than offset by $7.5 million of additional ADITC amortization. Idaho Power did not record any additional ADITC amortization in 2022.

Overview of General Factors and Trends Affecting Results of Operations and Financial Condition

IDACORP's and Idaho Power's results of operations and financial condition are affected by a number of factors, and the impact of those factors is discussed in more detail below in this MD&A. To provide context for the discussion elsewhere in this report, some of the more notable factors are as follows:

•Economic Conditions and Loads: Economic conditions impact consumer demand for energy, revenues, collectability of accounts, the volume of wholesale energy sales, and the need to construct and improve infrastructure, purchase power, and implement programs to meet customer load demands. In recent years, Idaho Power has seen significant growth in the number of customers in its service area. Over the twelve months ended June 30, 2023, Idaho Power's customer count grew by 2.1 percent. While inflationary and volatile economic conditions could slow the rate of customer growth in the near-term, Idaho Power expects its number of customers and, to a greater extent its load due to anticipated commercial and industrial customer growth, to increase in the foreseeable future.

Idaho Power is preparing its 2023 Integrated Resource Plan (IRP), its 20-year forecast of power demand and supply options. The 2023 preliminary IRP assumptions include significant large commercial and industrial additions in the 5-year forecasted annual growth rate, including potential load from new facilities recently announced by Meta Platforms, Inc. and Micron. Included in the below table are Idaho Power's preliminary load forecast assumptions the company anticipates using in the 2023 IRP as of the date of this report, and for comparison purposes, the analogous average annual growth rates Idaho Power used in the prior two IRPs.


	5-Year Forecasted Annual Growth Rate		20-Year Forecasted Annual Growth Rate
	Retail Sales (Billed MWh)	Annual Peak (Peak Demand)	Retail Sales (Billed MWh)	Annual Peak (Peak Demand)
2023 IRP (preliminary)	5.5%	3.7%	2.2%	1.8%
2021 IRP	2.6%	2.1%	1.4%	1.4%
2019 IRP	1.3%	1.4%	1.0%	1.2%

Idaho Power believes that existing and sustained growth in customers, load, and peak demand for electricity, along with changes in the regional transmission markets that have constrained the availability of transmission outside Idaho Power’s service area to import energy during peak load periods, require Idaho Power to increase its investment in capacity resources, transmission, and distribution infrastructure. This includes the Boardman-to-Hemingway and Gateway West transmission projects, along with other capacity and energy resources contemplated by the procurement of resources described in the "Rate Base Growth and Infrastructure Investment" section below in this MD&A.

Table of Contents

•Rate Base Growth and Infrastructure Investment: The rates established by the IPUC, OPUC, and FERC are determined with the intent to provide an opportunity for Idaho Power to recover authorized operating expenses and depreciation and earn a reasonable return on “rate base.” Rate base is generally determined by reference to the original cost (net of accumulated depreciation) of utility plant in service and certain other assets, subject to various adjustments for deferred income taxes and other items. Over time, rate base is increased by additions to utility plant in service and reduced by depreciation of utility plant and write-offs as authorized by the IPUC and OPUC. Idaho Power is pursuing significant enhancements to its utility infrastructure in an effort to maintain system reliability, ensure an adequate supply of electricity, and provide service to new customers, including major ongoing transmission projects such as the Boardman-to-Hemingway and Gateway West projects. Idaho Power's existing hydropower and thermal generation facilities also require continuing upgrades and equipment replacement, and the company is undertaking a significant relicensing effort for the Hells Canyon Complex (HCC), its largest hydropower generation resource. Idaho Power intends to pursue timely inclusion of any significant completed capital projects into rate base as part of a future general rate case or other appropriate regulatory proceeding.

As noted previously, Idaho Power believes that existing and sustained growth in customers, load, and peak demand for electricity, along with transmission constraints, has created the need for Idaho Power to acquire significant generation and storage resources to meet energy and capacity needs over the next several years. Idaho Power expects to spend more than $600 million from 2023 through 2027 on resource additions to address projected energy and capacity deficits. For more information about forecasted capital expenditures and expected rate base growth, see the "Liquidity and Capital Resources" section of this MD&A.

•Regulation of Rates and Cost Recovery; General Rate Case Filing: The prices that Idaho Power is authorized to charge for its electric and transmission service are a critical factor in determining IDACORP's and Idaho Power's results of operations and financial condition. Those rates are established by state regulatory commissions and the FERC and are intended to allow Idaho Power an opportunity to recover its expenses and earn a reasonable return on investment. Idaho Power focuses on timely recovery of its costs through filings with its regulators, working to put in place innovative regulatory mechanisms, and prudent management of expenses and investments. Idaho Power has a regulatory settlement stipulation in Idaho that includes provisions for the accelerated amortization of ADITC to help achieve a minimum 9.4 percent Idaho-jurisdiction return on year-end equity (Idaho ROE). The settlement stipulation also provides for the potential sharing between Idaho Power and its Idaho customers of Idaho-jurisdictional earnings in excess of a 10.0 percent Idaho ROE, which would adjust to the authorized return on equity determined in the next general rate case. The settlement stipulation has no expiration date but the minimum Idaho ROE would revert back to 95 percent of the authorized return on equity determined in the next Idaho general rate case. The specific terms of the settlement stipulation are described in Note 3 - "Regulatory Matters" to the consolidated financial statements included in the 2022 Annual Report.

Idaho Power filed a general rate case to adjust base customer rates in Idaho on June 1, 2023. Idaho Power expects a general rate case filing in Oregon likely to follow in late 2023 or 2024. The filing is described more fully in Note 3 - "Regulatory Matters" to the condensed consolidated financial statements included in this report. Several factors impacted Idaho Power’s filing of its Idaho general rate case including the increase in depreciation expense from rate-base eligible assets as they are placed into service (including its battery storage projects already placed in-service or expected to be in-service in 2023), the significant amounts of capital expenditures Idaho Power has made since its last general rate case filed in 2011, the expected financing costs for capital expenditures in a higher interest-rate environment, and, to a lesser extent, the inflationary pressures on other O&M expenses described above. Idaho Power expects the processing of its general rate case in Idaho will span at least seven months before new rates will be in effect. In Oregon, Idaho Power expects that processing of a general rate case would take approximately ten months.

•Weather Conditions: Weather and agricultural growing conditions have a significant impact on Idaho Power's energy sales. Relatively low and high temperatures result in greater energy use for heating and cooling, respectively. During the agricultural growing season, which in large part occurs during the second and third quarters of each year, irrigation customers use electricity to operate irrigation pumps, and weather conditions, such as a prolonged winter, can impact the timing and extent of use of those pumps. Idaho Power also has tiered rates and seasonal rates, which contribute to increased revenues during higher-load periods, most notably during the third quarter of each year when overall customer demand is highest. Much of the adverse or favorable impact of weather on sales of energy to residential and small commercial customers is mitigated through the Idaho FCA mechanism, which is described in Note 3 - "Regulatory Matters" to the condensed consolidated financial statements included in this report.

Further, as Idaho Power's hydropower facilities comprise over one-half of Idaho Power's nameplate generation capacity, precipitation levels impact the mix of Idaho Power's generation resources. When hydropower generation

Table of Contents

decreases, Idaho Power must rely on more expensive generation sources and purchased power. When favorable hydropower generating conditions exist for Idaho Power, they also may exist for other Pacific Northwest hydropower facility operators, lowering regional wholesale market prices and impacting the revenue Idaho Power receives from wholesale energy sales. Much of the adverse or favorable impact of this volatility is addressed through the Idaho and Oregon power cost adjustment mechanisms, which lessen the potential earnings benefit or detriment of volatile hydrological conditions and their impact on overall power supply costs. For 2023, Idaho Power expects generation from its hydropower resources to be in the range of 6.0 to 7.5 million MWh, compared with 5.3 million MWh of hydropower generation in 2022 and a 30-year average annual total of 7.7 million MWh.

•Mitigation of Impact of Fuel and Purchased Power Expense: In addition to hydropower generation, Idaho Power relies significantly on natural gas and coal to fuel its generation facilities and on power purchases in the wholesale markets. Fuel costs are impacted by electricity sales volumes, the terms and conditions of contracts for fuel, Idaho Power's generation capacity, the availability of hydropower generation resources, transmission capacity, energy market prices, and Idaho Power's hedging of fuel and power costs. Purchased power costs are impacted by the terms and conditions of contracts for purchased power, the rate of expansion of alternative energy generation sources such as wind or solar energy, generation resource maintenance outages, and wholesale energy market prices. The Idaho and Oregon power cost adjustment mechanisms mitigate in large part the potential adverse earnings impacts to Idaho Power of fluctuations in power supply costs. Idaho Power also has an energy risk management and hedging program designed to mitigate some, but not all, of the price risk associated with volatile and elevated power supply and fuel costs. However, collection from customers or return to customers of most of the difference between actual power supply costs compared with those included in retail rates is deferred to a subsequent period, which can affect Idaho Power’s operating cash flow and liquidity until those costs are recovered from or returned to customers.

•Regulatory and Environmental Compliance Costs; Coal Plant Retirements: Idaho Power is subject to extensive federal and state laws, policies, and regulations, as well as regulatory actions and audits by agencies and quasi-governmental agencies, including the FERC, the North American Electric Reliability Corporation, and the Western Electricity Coordinating Council. Compliance with these requirements directly influences Idaho Power's operating environment and affects Idaho Power's operating costs. Moreover, environmental laws and regulations may increase the cost of constructing new facilities, may increase the cost of operating generation plants, may require that Idaho Power install additional pollution control devices at existing generating plants, may result in penalties for non-compliance, even where inadvertent, or may require that Idaho Power curtail or cease operating certain generation plants. Idaho Power expects to spend significant amounts on environmental compliance and controls for the foreseeable future. Due to economic factors in part associated with the costs of compliance with environmental regulation, Idaho Power accelerated the retirement date of its jointly-owned coal-fired generating plant in Valmy, Nevada (Valmy plant), ceasing coal-fired operations at one unit in 2019 and planning to cease its participation in coal-fired operations at the remaining unit by year-end 2025. In June 2022, the IPUC approved Idaho Power's request to allow the coal-related assets at the Jim Bridger plant to be fully depreciated and recovered by end-of-year 2030. The IPUC's Bridger Order related to Idaho Power's plan to cease its participation in coal-related operations at the Jim Bridger plant by 2028 is described more fully in Note 3 - "Regulatory Matters" to the condensed consolidated financial statements included in this report.

•Water Management and Relicensing of Hydropower Projects: Because of Idaho Power's reliance on stream flow in the Snake River and its tributaries, Idaho Power participates in numerous proceedings and venues that may affect its water rights, seeking to preserve the long-term availability of its rights for its hydropower projects. Also, Idaho Power is involved in renewing its long-term federal licenses for the HCC, its largest hydropower generation source, and for American Falls, its second largest hydropower generation source. Given the number of parties involved, Idaho Power's relicensing costs have been and are expected to continue to be substantial. As of the date of this report, Idaho Power cannot determine the ultimate terms of, and costs associated with, any resulting long-term licenses for the HCC or American Falls hydropower facilities.

•Wildfire Mitigation Efforts: In recent years, the western United States has experienced an increasing trend in the degree of annual destruction from wildfires. A variety of factors have contributed to this trend including climate change, increased wildland-urban interfaces, historical land management practices, and overall wildland and forest health. While Idaho Power has not experienced to-date the extent of catastrophic wildfires within its service area that have occurred in California and elsewhere in the western United States, Idaho Power is taking a proactive approach to wildfire threat in its service area and transmission corridors. Idaho Power has adopted a Wildfire Mitigation Plan (WMP) that outlines actions Idaho Power is taking or is working to implement in the future to reduce wildfire risk and to strengthen the resiliency of its transmission and distribution system to wildfires. Idaho Power's approach to achieve these objectives includes identifying areas subject to elevated risk; system hardening programs, vegetation

Table of Contents

management, and field personnel practices to mitigate wildfire risk; incorporating current and forecasted weather and field conditions into operational practices; public safety power shutoff protocols adopted in 2022; and evaluating the performance and effectiveness of the strategies identified in the WMP through metrics and monitoring. In regulatory orders received in June 2021 and March 2023, the IPUC authorized Idaho Power to defer, for future amortization, the Idaho jurisdictional share of actual incremental O&M expenses and depreciation expense of certain capital investments necessary to implement the WMP. The IPUC orders related to the WMP are described in more detail in the "Regulatory Matters" section of this MD&A.

RESULTS OF OPERATIONS

This section of MD&A takes a closer look at the significant factors that affected IDACORP’s and Idaho Power’s earnings during the three months and six months ended June 30, 2023. In this analysis, the results for the three months and six months ended June 30, 2023, are compared with the same periods in 2022.

The table below presents Idaho Power’s energy sales and supply (in thousands of MWh) for the three months and six months ended June 30, 2023 and 2022.

Weather-related information for Boise, Idaho, for the three months and six months ended June 30, 2023 and 2022, is presented in the table below. While Boise, Idaho weather conditions are not necessarily representative of weather conditions throughout Idaho Power's service area, the greater Boise area has the majority of Idaho Power's customers and is included for illustrative purposes.


	Three months ended June 30,			Six months ended June 30,
	2023	2022	Normal (2)	2023	2022	Normal (2)
Heating degree-days(1)	577	909	685	3,169	3,505	3,087
Cooling degree-days(1)	246	157	188	246	157	188
Precipitation (inches)	3.0	4.6	3.4	6.7	7.3	7.2

(1) Heating and cooling degree-days are common measures used in the utility industry to analyze the demand for electricity and indicate when a customer would use electricity for heating and cooling. A degree-day measures how much the average daily temperature varies from 65 degrees. Each degree of temperature above 65 degrees is counted as one cooling degree-day, and each degree of temperature below 65 degrees is counted as one heating degree-day.

(2) Normal heating degree-days and cooling degree-days elements are, by convention, the arithmetic mean of the elements computed over 30 consecutive years. The normal amounts are the sum of the monthly normal amounts. These normal amounts are computed by the National Oceanic and Atmospheric Administration.

Sales Volume and Generation: Retail sales volumes increased 1 percent and 2 percent in the second quarter and first six months of 2023, respectively, compared with the same periods in 2022, primarily due to growth in the number of Idaho Power customers. The number of Idaho Power's customers grew by 2.1 percent over the prior twelve months, contributing to the higher volumes.

Table of Contents

Total system generation increased 14 percent for the second quarter and 10 percent in the first six months of 2023 compared with the same periods in 2022, comprised of an increase in hydropower generation and natural gas generation, partially offset by decreased coal generation. For more information on the changes in generation, see the "Operating Expenses" section below in this MD&A.

The financial impacts of fluctuations in wholesale energy sales, purchased power, fuel expense, and other power supply-related expenses are addressed in Idaho Power's Idaho and Oregon power cost adjustment mechanisms, which are described below in "Power Cost Adjustment Mechanisms."

(1) The FCA mechanism is an alternative revenue program and does not represent revenue from contracts with customers.

(2) As part of its January 30, 2009 general rate case order, the IPUC is allowing Idaho Power to recover a portion of the allowance for funds used during construction (AFUDC) on construction work in progress related to the HCC relicensing process, even though the relicensing process is not yet complete and the costs have not been moved to electric plant in service. Idaho Power is collecting approximately $8.8 million annually in the Idaho jurisdiction but is deferring revenue recognition of the amounts collected until the license is issued and the accumulated license costs approved for recovery are placed in service.

Changes in rates, changes in customer usage, customer growth, and changes in FCA mechanism revenues are the primary reasons for fluctuations in retail revenues from period to period. The primary influences on customer usage of electricity are weather, economic conditions, and energy efficiency. Extreme temperatures increase sales to customers who use electricity for cooling and heating, while moderate temperatures decrease sales. Precipitation levels and the timing of precipitation during the agricultural growing season also affect sales to customers who use electricity to operate irrigation pumps. Rates are also seasonally adjusted, providing for higher rates during peak load periods, and residential customer rates are tiered, providing for higher rates based on higher levels of usage. The seasonal and tiered rate structures contribute to seasonal fluctuations in revenues and earnings.

Retail revenues increased $30.1 million and $65.0 million during the second quarter and first six months of 2023, respectively, compared with the same periods in 2022. The factors affecting retail revenues during the periods are discussed below.

Table of Contents

•Rates: Average customer rates, excluding amounts related to the power cost adjustment mechanisms, increased retail revenues by $2.4 million and $10.8 million, respectively, for the first three and six months ended June 30, 2023, compared with the same periods in 2022, due primarily to the June 1, 2022, rate increase for Idaho Power's retail customers related to the Bridger Order. Customer rates also include the collection from customers of amounts related to the power cost adjustment mechanisms, which increased revenues by $22.7 million and $44.4 million in the second quarter and first six months of 2023, respectively, compared with the same periods of 2022. The amount collected from customers in rates under the power cost adjustment mechanisms has relatively little effect on operating income as a corresponding amount is recorded as expense in the same period it is collected through rates.

•Customers: Customer growth of 2.1 percent during the twelve months ended June 30, 2023, increased retail revenues by $6.7 million and $12.0 million in the second quarter and first six months of 2023, respectively, compared with the same periods of 2022.

•Usage: Decreased usage (on a per customer basis), primarily by industrial customers, decreased retail revenues by $1.9 million and $1.2 million in the second quarter and first six months of 2023, respectively, compared with the same periods of 2022. Usage per industrial customer decreased 5 percent and 3 percent in the second quarter and first six months of 2023, respectively, compared with the same periods of 2022. In addition to slightly lower economic activity in a few industrial sectors in both periods in 2023, operation of a customer-owned-and-operated co-generation facility reduced industrial customer energy usage during the second quarter of 2023 compared with the second quarter of 2022 when the co-generation facility was down for maintenance.

•Idaho FCA Revenue: The FCA mechanism, applicable to Idaho residential and small commercial customers, adjusts revenue each year to accrue, or defer, the difference between the authorized fixed-cost recovery amount per customer and the actual fixed costs per customer recovered by Idaho Power through volume-based rates during the year. Lower usage (on a per customer basis) by residential and small commercial customers during the second quarter of 2023 increased the amount of FCA revenue accrued by $0.2 million compared with the same period in 2022. Higher usage (on a per customer basis) by residential and small commercial customers during the first six months of 2023 decreased the amount of FCA revenue accrued by $1.0 million compared with the same period in 2022.

Wholesale Energy Sales: Wholesale energy sales consist primarily of long-term sales contracts, sales of surplus system energy, and sales into the energy imbalance market in the western United States, and do not include derivative transactions. The table below presents Idaho Power’s wholesale energy sales for the three and six months ended June 30, 2023 and 2022 (in thousands, except for revenue per MWh amounts).

Wholesale MWh sold	330		121		538		149
Wholesale energy revenues per MWh	$	46.06	$	57.69	$	84.38	$	67.21

In the second quarter and during the first six months of 2023, wholesale energy revenues increased $8.2 million and $35.4 million, respectively, compared with the same periods of 2022, due primarily to increases in volumes sold. Wholesale MWh sold increased primarily due to higher hydro generation that resulted in more energy available for opportunistic market sales. The increase in wholesale volumes sold during the six months ended June 30, 2023, was also partially due to energy originally purchased under derivative forward contracts to be bundled with renewable energy credits, but the energy was ultimately sold in the wholesale markets in the first quarter of 2023. Those sales increased wholesale energy revenues by $16.7 million in the first six months of 2023 and a corresponding amount was recorded in purchased power on the condensed consolidated statements of income. The financial impacts of fluctuations in wholesale energy sales are largely mitigated by Idaho Power's Idaho and Oregon power cost adjustment mechanisms, which are described below in this section of the MD&A under "Power Cost Adjustment Mechanisms."

Transmission Wheeling-Related Revenues: Transmission wheeling-related revenues increased $1.7 million, or 9 percent, and $6.8 million, or 20 percent, during the second quarter and first six months of 2023, respectively, compared with the same periods of 2022, primarily due to elevated energy prices in the western United States. Also, Idaho Power's OATT rates were approximately 1 percent higher in the first half of 2023 compared to the first half of 2022.

Energy Efficiency Program Revenues: In both Idaho and Oregon, energy efficiency riders fund energy efficiency program expenditures. Expenditures funded through the riders are reported as an operating expense with an equal amount recorded in revenues, resulting in no net impact on earnings. The cumulative variance between expenditures and amounts collected through the rider is recorded as a regulatory asset or liability. A liability balance indicates that Idaho Power has collected more than it

Table of Contents

has spent and an asset balance indicates that Idaho Power has spent more than it has collected. At June 30, 2023, Idaho Power's energy efficiency rider balances were regulatory liabilities of $1.2 million in the Idaho jurisdiction and $0.6 million in the Oregon jurisdiction.

Operating Expenses

Purchased Power: The table below presents Idaho Power’s purchased power expenses and volumes for the three months and six months ended June 30, 2023 and 2022 (in thousands, except for per MWh amounts).


	Three months ended June 30,				Six months ended June 30,
	2023		2022		2023		2022
Expense
PURPA contracts	$	45,198	$	48,607	$	93,429	$	88,603
Other purchased power (including wheeling)	46,262		43,120		169,125		88,548
Total purchased power expense	$	91,460	$	91,727	$	262,554	$	177,151

PURPA contracts	813		855		1,503		1,462
Other purchased power	1,043		868		2,253		2,042
Total MWh purchased	1,856		1,723		3,756		3,504
Average cost per MWh from PURPA contracts	$	55.59	$	56.85	$	62.16	$	60.60

Weighted average - all sources	$	49.28	$	53.24	$	69.90	$	50.56

Purchased power expense decreased $0.3 million in the second quarter of 2023 compared with the second quarter of 2022, due primarily to a decrease in the weighted average purchased power prices compared with the second quarter of 2022. Purchased power expense increased $85.4 million, or 48 percent, in the first six months of 2023 compared with the same period of 2022, due primarily to elevated wholesale energy prices in the western United States and, to a lesser extent, higher generation from projects under PURPA contracts and other purchased power.

Fuel Expense: The table below presents Idaho Power’s fuel expenses and thermal generation for the three months and six months ended June 30, 2023 and 2022 (in thousands, except for per MWh amounts).


	Three months ended June 30,				Six months ended June 30,
	2023		2022		2023		2022
Expense
Coal	$	8,665	$	22,346	$	25,729	$	50,005

Average cost per MWh - Coal	$	48.14	$	28.76	$	42.32	$	31.35
Average cost per MWh - Natural gas	$	73.12	$	67.44	$	79.58	$	47.20
Weighted average, all sources	$	63.89	$	36.00	$	66.96	$	35.88

The majority of the fuel for Idaho Power’s jointly-owned coal-fired plants is purchased through long-term contracts, including purchases from BCC, a one-third owned joint venture of IERCo. The price of coal from BCC is subject to fluctuations in mine operating expenses, geologic conditions, and production levels. BCC supplies approximately two-thirds of the coal used by the Jim Bridger plant. Natural gas is mainly purchased on the regional wholesale spot market at published index prices. In addition to commodity (variable) costs, both natural gas and coal expenses include costs that are more fixed in nature for items such as

Table of Contents

capacity charges, transportation, and fuel handling. Period to period variances in fuel expense per MWh are noticeably impacted by these fixed charges when generation output is substantially different between the periods.

Fuel expense decreased $3.3 million, or 10 percent, in the second quarter of 2023 compared with the second quarter of 2022, due primarily to a 52 percent increase in hydroelectric generation, which reduced Idaho Power's utilization of thermal generation. Fuel expense increased $40.1 million, or 50 percent, in the first six months of 2023 compared with the same periods of 2022, despite lower total thermal generation. The increase in fuel expense in the first six months of 2023 compared with the same period of 2022, was primarily due to higher natural gas market prices in early 2023, which resulted in an increase in the average cost per MWh of natural gas generation. The mix of Idaho Power's thermal generation between natural gas and coal in the second quarter and first half of 2023 compared with the same periods of 2022 was affected by fluctuations in natural gas prices and Idaho Power optimizing its dispatch of coal generation resources in an effort to help ensure adequate coal supply during its period of peak demand in 2023. To preserve coal supply for peak periods, Idaho Power relied more on natural gas-fired generation to meet customer demand during the second quarter and first half of 2023 compared with the same periods in 2022.

Included in fuel expense are losses and gains on settled financial gas hedges entered into in accordance with Idaho Power's energy risk management policy. In the second quarter of 2023, losses on financial gas hedges of $11.4 million increased natural gas fuel expense, while in the second quarter of 2022 and the first six months of 2023 and 2022, gains on financial gas hedges of $3.0 million, $12.1 million, and $4.5 million, respectively, reduced natural gas fuel expense. Most of these realized hedging losses and gains are passed on to customers through the power cost adjustment mechanisms described below.

Power Cost Adjustment Mechanisms: Idaho Power's power supply costs (primarily purchased power and fuel expense, less wholesale energy sales) can vary significantly from year to year. Volatility of power supply costs arises from factors such as weather conditions, wholesale market prices, volumes of power purchased and sold in the wholesale markets, Idaho Power's hydropower and thermal generation volumes and fuel costs, generation plant availability, and retail loads. To address the volatility of power supply costs, Idaho Power's power cost adjustment mechanisms in the Idaho and Oregon jurisdictions allow Idaho Power to recover from customers, or refund to customers, most of the fluctuations in power supply costs. The Idaho-jurisdiction power cost adjustment (PCA) includes a cost or benefit sharing ratio that allocates the deviations in net power supply expenses between customers (95 percent) and Idaho Power (5 percent), with the exception of PURPA power purchases and demand response program incentives, which are allocated 100 percent to customers. The Idaho deferral period, or PCA year, runs from April 1 through March 31. Amounts deferred or accrued during the PCA year are primarily recovered or refunded during the subsequent June 1 through May 31 period. However, the IPUC directed Idaho Power to spread recovery of the March 31, 2023 PCA deferral balance over a two-year period from June 1, 2023, to May 31, 2025. Because of the power cost adjustment mechanisms, the primary financial impacts of power supply cost variations are that cash is paid out but recovery from customers does not occur until a future period, or cash that is collected is refunded to customers in a future period, resulting in fluctuations in operating cash flows from year to year.

The table that follows presents the components of the Idaho and Oregon power cost adjustment mechanisms for the three months and six months ended June 30, 2023 and 2022 (in thousands).


	Three months ended June 30,				Six months ended June 30,
	2023		2022		2023		2022
Power supply cost accrual (deferral)	$	34,917	$	(1,026)	$	(25,351)	$	3,457
Oregon power supply cost accrual	312		—		336		—
Amortization of prior year authorized balances	14,400		600		23,307		(4,282)
Total power cost adjustment (income statement)	$	49,629	$	(426)	$	(1,708)	$	(825)

The power supply accruals (deferrals) represent the portion of the power supply cost fluctuations accrued (deferred) under the power cost adjustment mechanisms. When actual power supply costs are lower than the amount forecasted in power cost adjustment rates, most of the difference is accrued as an increase to a regulatory liability or decrease to a regulatory asset. When actual power supply costs are higher than the amount forecasted in power cost adjustment rates, most of the difference is deferred as an increase to a regulatory asset or decrease to a regulatory liability. During the second quarter of 2023, improved hydropower generation led to lower actual power supply costs compared with the forecasted amount, which resulted in an accrual of power supply costs by the mechanism. During the first six months of 2023, higher purchased power and fuel costs led to higher actual power supply costs compared with the forecasted amount, which resulted in an increase in the amount of power supply costs deferred by the mechanism. The amortization of the prior year’s balances represents the offset to the

Table of Contents

amounts being collected or refunded in the current power cost adjustment year that were deferred or accrued in the prior PCA year.

Other O&M Expenses: Total other O&M expenses decreased $3.4 million, or 3 percent, and $3.5 million, or 2 percent, in the second quarter and first six months of 2023, respectively, compared with the same periods of 2022, due primarily to lower expenses from scheduled cyclical plant maintenance projects compared with the same period in 2022, offset partially by inflationary pressures on labor-related and other costs.

Income Taxes

IDACORP and Idaho Power income tax expense in the first six months of 2023 was consistent with the first six months of 2022 as increased taxes from higher pre-tax income was more than offset by $7.5 million of additional ADITC amortization. Idaho Power did not record any additional ADITC amortization in 2022. For information relating to IDACORP's and Idaho Power's computation of income tax expense, see Note 2 - "Income Taxes" to the condensed consolidated financial statements included in this report.

LIQUIDITY AND CAPITAL RESOURCES

Overview

Idaho Power funds its liquidity needs for capital expenditures through cash flows from operations, debt offerings, commercial paper markets, credit facilities, a term loan facility, and capital contributions from IDACORP. Idaho Power periodically files for rate adjustments for recovery of operating costs and capital investments to provide the opportunity to align Idaho Power's earned returns with those allowed by regulators.

As of July 28, 2023, IDACORP's and Idaho Power's access to debt, equity, and credit arrangements included:

•their respective $100 million and $300 million revolving credit facilities;

•IDACORP's shelf registration statement filed with the U.S. Securities and Exchange Commission (SEC) on May 16, 2022, which may be used for the issuance of debt securities and common stock;

•Idaho Power's shelf registration statement filed with the SEC on May 16, 2022, which may be used for the issuance of first mortgage bonds and other debt securities; $630 million remains available for issuance pursuant to state regulatory authority; and

•IDACORP's and Idaho Power's issuance of commercial paper, which may be issued up to an amount equal to the available credit capacity under their respective credit facilities.

In March 2023, Idaho Power issued the following long-term debt with the proceeds being used for general corporate purposes, including repaying outstanding commercial paper and long-term debt and funding Idaho Power's capital projects:

•$60 million of 5.06% first mortgage bonds, secured medium-term notes, Series N, maturing in March 2043;

•$62 million of 5.20% first mortgage bonds, secured medium-term notes, Series N, maturing in March 2053; and

•$400 million of 5.50% first mortgage bonds, secured medium-term notes, Series M, maturing in March 2053.

In March through May 2023, a portion of the proceeds from the March 2023 issuances was used to repay outstanding commercial paper, $150 million in principal amount from a March 2022 term loan agreement, and $75 million in principal amount of maturing 2.50% first mortgage bonds, Series I.

In addition to the discussion above, which includes notable liquidity developments in 2023, more information on IDACORP's and Idaho Power's debt, equity, and credit facilities is included in Part II, Item 7 - "MD&A – Financing Programs and Available Liquidity" in the 2022 Annual Report.

IDACORP and Idaho Power monitor capital markets with a view toward opportunistic debt and equity transactions, taking into account current and potential future long-term needs. As a result, IDACORP may issue debt securities or common stock, and Idaho Power may issue first mortgage bonds or other debt securities, if the companies believe terms available in the capital markets are favorable and that issuances would be financially prudent.

Based on planned capital expenditures and other O&M expenses, the companies believe they will be able to meet capital and debt service requirements and fund corporate expenses during at least the next twelve months with a combination of existing

Table of Contents

cash, operating cash flows generated by Idaho Power's utility business, availability under existing credit facilities, access to commercial paper, short-term and long-term debt markets, and equity issuances.

IDACORP and Idaho Power generally seek to maintain capital structures of approximately 50 percent debt and 50 percent equity. Maintaining this ratio influences IDACORP's and Idaho Power's debt and equity issuance decisions. As of June 30, 2023, IDACORP's and Idaho Power's capital structures, as calculated for purposes of applicable debt covenants, were as follows:


	IDACORP	Idaho Power
Debt	47%	48%
Equity	53%	52%

IDACORP and Idaho Power generally maintain their cash and cash equivalents in highly liquid investments, such as U.S. Treasury Bills, money market funds, and bank deposits.

At June 30, 2023, IDACORP and Idaho Power believed they were in compliance with all credit facility and long-term debt covenants. Further, IDACORP and Idaho Power do not anticipate they will be in violation or breach of their respective debt covenants during 2023.

Operating Cash Flows

IDACORP’s and Idaho Power's principal sources of cash flows from operations are Idaho Power's sales of electricity and transmission capacity. Significant uses of cash flows from operations include the purchase of fuel and power, other operating expenses, interest, income taxes, and plan contributions. Operating cash flows can be significantly influenced by factors such as weather conditions, rates and the outcome of regulatory proceedings, and economic conditions. As fuel and purchased power are significant uses of cash, Idaho Power has regulatory mechanisms in place that provide for the deferral and recovery of the majority of the fluctuation in those costs. However, if actual costs rise above the level currently allowed in retail rates, deferral balances increase (reflected as a regulatory asset), negatively affecting operating cash flows until such time as those costs, with interest, are recovered from customers.

IDACORP’s and Idaho Power’s operating cash inflows for the six months ended June 30, 2023, were $7 million and $1 million, respectively, a decrease in cash flows from operations of $149 million for IDACORP and $144 million for Idaho Power, when compared with the same period in 2022. With the exception of cash flows related to income taxes, IDACORP's operating cash flows are principally derived from the operating cash flows from Idaho Power. Significant items that affected the companies' operating cash flows in the first six months of 2023 when compared with the same period in 2022 were as follows:

•a $14 million increase in IDACORP and Idaho Power net income;

•changes in regulatory assets and liabilities, mostly related to the relative amounts of costs deferred and collected under the Bridger Order and wildfire mitigation cost deferral, decreased operating cash flows by $17 million; and

•changes in working capital balances due primarily to timing, including fluctuations as follows:

◦the changes in materials, supplies, and fuel stock decreased operating cash flows by $31 million for IDACORP and Idaho Power, which was primarily due to an increase in material and supply inventory offset by the timing of purchases and consumption of coal at Idaho Power's jointly-owned coal-fired generating plants; and

◦the changes in accounts and wages payable decreased operating cash flows by $115 million for IDACORP and $113 million for Idaho Power, which was primarily due to an increase in power supply costs and associated timing of payments.

Investing Cash Flows

Investing activities consist primarily of capital expenditures related to new construction of, and improvements to, Idaho Power’s generation, transmission, and distribution facilities. IDACORP’s and Idaho Power’s net investing cash outflows for the six months ended June 30, 2023, were $264 million and $263 million, respectively. Investing cash outflows for 2023 and 2022 were primarily for construction of utility infrastructure needed to address Idaho Power’s aging plant and equipment, customer growth, and environmental and regulatory compliance requirements. Significant items and transactions that affected investing cash flows in the first six months of 2023 were as follows:

Table of Contents

•IDACORP’s and Idaho Power’s investing cash outflows for 2023 included $274 million of additions to property, plant and equipment, including $47 million spent on battery storage projects, and at June 30, 2023, $49 million was accrued in accounts payable on their consolidated balances sheets related to battery storage projects;

•IDACORP’s and Idaho Power's investing cash inflows for 2023 included $9 million from Boardman-to-Hemingway project joint permitting participants relating to a portion of the permitting expenditures and a security deposit;

•IDACORP’s and Idaho Power's investing cash outflows for 2023 included a $5 million investment in IERCo, a wholly-owned subsidiary of Idaho Power; and

•IDACORP’s and Idaho Power's investing cash inflows for 2023 included $4 million in sales of equity securities, held in a rabbi trust, which is designated to provide funding for obligations related to Idaho Power's security plan for senior management employees.

Financing Cash Flows

Financing activities provide supplemental cash for both day-to-day operations and capital requirements, as needed. IDACORP's and Idaho Power's net financing cash inflows for the six months ended June 30, 2023, were $214 million and $257 million, respectively. Idaho Power funds liquidity needs for capital investment, working capital, managing commodity price risk, dividends, and other financial commitments through cash flows from operations, debt offerings, commercial paper markets, credit facilities, a term loan facility, and capital contributions from IDACORP. IDACORP funds its cash requirements, such as payment of taxes, payment of dividends, capital contributions to Idaho Power, and non-utility expenses allocated to IDACORP, through cash flows from operations, commercial paper markets, sales of common stock, and credit facilities. Significant items and transactions that affected financing cash flows in the first six months of 2023 were as follows:

•in March 2023, Idaho Power repaid $100 million in principal amount of a March 2022 term loan agreement;

•in March 2023, Idaho Power issued $60 million in principal amount of 5.06% first mortgage bonds, secured medium-term notes, Series N, maturing in March 2043;

•in March 2023, Idaho Power issued $62 million in principal amount of 5.20% first mortgage bonds, secured medium-term notes, Series N, maturing in March 2053;

•in March 2023, Idaho Power issued $400 million in principal amount of 5.50% first mortgage bonds, secured medium-term notes, Series M, maturing in March 2053;

•in April 2023, Idaho Power repaid, at maturity, $75 million in principal amount of 2.50% first mortgage bonds, secured medium-term notes, Series I;

•in May 2023, Idaho Power repaid $50 million in principal amount of a March 2022 term loan agreement; and

•IDACORP and Idaho Power paid dividends of $81 million and $41 million in 2023, respectively.

Impact of Credit Ratings on Liquidity and Collateral Obligations

IDACORP’s and Idaho Power’s access to capital markets, including the commercial paper market, and their respective financing costs in those markets, depend in part on their respective credit ratings. There have been no changes to IDACORP's or Idaho Power's ratings by Standard & Poor’s Ratings Services or Moody’s Investors Service from those included in the 2022 Annual Report. However, any rating can be revised upward or downward or withdrawn at any time by a rating agency if it decides that the circumstances warrant the change.

Idaho Power maintains margin agreements relating to its wholesale commodity contracts that allow performance assurance collateral to be requested of and/or posted with certain counterparties. As of June 30, 2023, Idaho Power had posted $44 million of cash performance assurance collateral related to these contracts. Should Idaho Power experience a reduction in its credit rating on its unsecured debt to below investment grade, Idaho Power could be subject to requests by its wholesale counterparties to post additional performance assurance collateral, and counterparties to derivative instruments and other forward contracts could request immediate payment or demand immediate ongoing full daily collateralization on derivative instruments and contracts in net liability positions. Based upon Idaho Power’s current energy and fuel portfolio and market conditions as of June 30, 2023, the amount of additional collateral that could be requested upon a downgrade to below investment grade is approximately $19 million. To minimize capital requirements, Idaho Power actively monitors its portfolio exposure and the potential exposure to additional requests for performance assurance collateral through sensitivity analysis.

Capital Requirements

Idaho Power's cash capital expenditures, excluding AFUDC, were $265 million during the six months ended June 30, 2023. The table below presents Idaho Power's estimated accrual-basis additions to property, plant, and equipment for 2023 (including amounts incurred to-date) through 2027 (in millions of dollars). The amounts in the table exclude AFUDC but include net costs of removing assets from service that Idaho Power expects would be eligible to be included in rate base in future rate case proceedings. Given the uncertainty associated with the timing of infrastructure projects and associated expenditures, actual expenditures and their timing could deviate substantially from those set forth in the table. The capital expenditure table below assumes, among other projects, construction and ownership of a number of capacity resources identified in Idaho Power's RFP, 2021 IRP, and preliminary 2023 IRP modeling in order to safely and reliably serve the company's customers. The timing and amount of actual constructed projects and capital expenditures could be affected by Idaho Power’s ability to timely obtain labor or materials at reasonable costs, supply chain disruptions and delays, regulatory determinations, inflationary pressures, macroeconomic conditions, or other issues, including those described below.


	2023	2024	2025-2027
Expected capital expenditures (excluding AFUDC)	$650-$700	$800-$850	$1,500-$1,700

Major Infrastructure Projects: Idaho Power is engaged in the development of a number of significant projects and has entered into arrangements with third parties concerning joint infrastructure development. The discussion below provides a summary of developments in certain of those projects since the discussion of these matters included in Part II, Item 7 - "MD&A - Capital Requirements" in the 2022 Annual Report. The discussion below should be read in conjunction with that report.

Table of Contents

Resource Additions to Address Projected Energy and Capacity Deficits: As noted previously, Idaho Power's existing and sustained growth in customers, load, and peak demand for electricity, along with transmission constraints, has created the need for Idaho Power to acquire significant generation, transmission, and storage resources to meet energy and capacity needs over the next several years. To help meet peak needs in 2023 through 2025, Idaho Power entered into or expects to enter into contracts to purchase, own, and operate approximately 300 MW of battery storage assets with expected useful lives of approximately 20 years, entered into a 20-year agreement to purchase the storage capacity from a 150-MW battery storage facility, and also entered into three power purchase agreements for the combined 340 MW output of planned third-party solar facilities with 20- to 25-year terms. As described in “Regulatory Matters” of this MD&A, Idaho Power plans to sell the output of two of these solar power purchase agreements totaling 240 MW exclusively to two large industrial customers under agreements modeled after Idaho Power’s proposed Clean Energy Your Way program. To help address the additional capacity deficits projected for 2026 through 2027, Idaho Power has issued an RFP for additional resources. The capital requirements table above includes capital expenditures of more than $600 million from 2023 through 2027 for resource additions to address projected energy and capacity deficits in those years. Depending on factors such as RFP results, the timing of project in-service dates, estimated load and resource balances and customer growth, the nature and quantity of resources owned versus acquired under power purchase agreements or similar agreements, and the outcome of regulatory proceedings, actual expenditures and their timing could deviate substantially from Idaho Power's expected expenditures.

Boardman-to-Hemingway Transmission Line: The Boardman-to-Hemingway line, a planned 300-mile, high-voltage transmission project between a substation near Boardman, Oregon, and the Hemingway substation near Boise, Idaho, is expected to provide transmission service to meet future resource needs. Material procurement and construction subcontract bid events are in progress and Idaho Power expects construction to begin in the second half of 2023. Given the status of ongoing activities and the construction period, Idaho Power expects the in-service date for the transmission line will be no earlier than 2026.

Until recently, Idaho Power had a joint funding agreement with PacifiCorp and BPA to pursue permitting of the project, with Idaho Power having an approximate 21 percent interest, BPA having an approximate 24 percent interest, and PacifiCorp having an approximate 55 percent interest in the permitting phase of the project. In March 2023, BPA, PacifiCorp, and Idaho Power signed various agreements to facilitate certain asset transfers and other coordination efforts among the parties as the transmission line moves toward construction. In particular, an agreement between Idaho Power and BPA transferred BPA’s total interest in the project to Idaho Power, increasing Idaho Power's interest to approximately 45 percent, and provided that Idaho Power will deliver transmission service to BPA's customers across southern Idaho. The agreement also required BPA to make a $10 million security payment to Idaho Power. On Idaho Power's condensed consolidated balance sheet, the agreement increased construction work in progress by $31 million for the acquired permitting interest, cash and cash equivalents by $10 million for the additional security payment, and other non-current liabilities by $41 million for Idaho Power's obligation to pay for the permitting interest and to return the security deposit to BPA. Payments to BPA for the permitting interest are expected to be made over a 15-year period beginning 10 years after energization of the transmission line project, while the security deposit is due to be returned to BPA upon energization.

Idaho Power has spent approximately $169 million, including Idaho Power's AFUDC, on the Boardman-to-Hemingway project through June 30, 2023. Pursuant to the terms of the joint funding arrangements, Idaho Power has received $107 million in reimbursement as of June 30, 2023, from project co-participants for their share of costs (including $31 million related to BPA's share, which was transferred to Idaho Power in March 2023 as part of the agreement described above). As of the date of this report, no material co-participant reimbursements are outstanding. The remaining joint permitting participant is obligated to reimburse Idaho Power for its share of any future project permitting expenditures or agreed upon early construction expenditures incurred by Idaho Power under the terms of the joint funding agreement.

The permitting phase of the Boardman-to-Hemingway project was subject to federal review and approval by various federal agencies. Federal agency records of decision have been received and all lawsuits challenging the federal rights-of-way have been resolved. In the separate State of Oregon permitting process, the state's EFSC approved Idaho Power's site certificate on September 27, 2022. The Oregon Department of Energy subsequently issued a final order and site certificate. Three parties filed appeals to the Oregon Supreme Court asking that court to overturn EFSC's approval of the Boardman-to-Hemingway site certificate. On March 9, 2023, the Oregon Supreme Court affirmed the EFSC's final order approving Idaho Power's site certificate.

In June 2023, Idaho Power and PacifiCorp executed a construction funding agreement and filed it with the FERC. Idaho Power anticipates that the agreement will go into effect upon meeting the conditions precedent contained in the agreement relating to acceptance of the agreement by the FERC, receipt of the CPCNs for Boardman-to-Hemingway from Oregon and Idaho for Idaho Power and Idaho and Wyoming for PacifiCorp, and Idaho Power and PacifiCorp consenting to the conditions contained within their respective CPCNs.

Table of Contents

As of June 2023, the IPUC, OPUC, and Wyoming Public Service Commission have granted, or made oral decisions approving, Idaho Power and PacifiCorp their respective CPCNs related to the construction of the Boardman-to-Hemingway project.

Total cost estimates for the project are trending toward the upper end of Idaho Power's estimated cost range of between $1.1 billion and $1.3 billion, including Idaho Power's AFUDC. The capital requirements table above includes approximately $430 million of Idaho Power's share of estimated costs (excluding AFUDC) related to the remaining permitting phase, design, material procurement, and construction phases of the project. The preliminary estimates of construction costs could change as the construction timeline nears and as the project participants obtain more detailed information on construction and material costs.

Gateway West Transmission Line: Idaho Power and PacifiCorp are pursuing the joint development of the Gateway West project, a high-voltage transmission lines project between a substation located near Douglas, Wyoming, and the Hemingway substation located near Boise, Idaho. In 2012, Idaho Power and PacifiCorp entered a joint funding agreement for permitting of the project. Idaho Power has expended approximately $57 million, including Idaho Power's AFUDC, for its share of the permitting phase of the project through June 30, 2023. As of the date of this report, Idaho Power estimates the total cost for its share of the project (including both permitting and construction) to be trending toward the upper end of the cost range between $300 million and $500 million, including AFUDC. The capital requirements table above includes approximately $40 million of Idaho Power's share of estimated costs (excluding AFUDC) for the permitting phase of the project and early construction costs, based on Idaho Power's current estimate that it may commence construction of applicable segments during that time period.

The permitting phase of the Gateway West project was subject to review and approval of the U.S. Bureau of Land Management (BLM). The BLM has published its records of decision for all segments of the transmission line. In late 2020, PacifiCorp completed construction and commissioned a 140-mile segment of its portion of the project in Wyoming. In March 2023, PacifiCorp initiated the pre-construction phase of 620 miles of 500-kV transmission line from the Populus substation near Downey, Idaho, to the Hemingway substation near Melba, Idaho. Idaho Power and PacifiCorp continue to coordinate the timing of next steps to best meet customer and system needs.

Defined Benefit Pension Plan Contributions

Idaho Power has no minimum contribution requirement to its defined benefit pension plan in 2023, and during the six months ended June 30, 2023, Idaho Power made a $10 million contribution. Idaho Power is considering contributing up to an additional $30 million to its pension plan during 2023 in a continued effort to balance the regulatory collection of these expenditures with the amount and timing of contributions, as well as to mitigate the cost of being in an underfunded position. The primary impact of pension contributions is on the timing of cash flows, as the timing of cost recovery lags behind contributions.

Contractual Obligations

IDACORP’s and Idaho Power’s contractual cash obligations have not materially changed during the six months ended June 30, 2023, except as disclosed in Note 5 – “Long-Term Debt” and Note 8 – “Commitments” to the condensed consolidated financial statements included in this report.

Dividends

The amount and timing of dividends paid on IDACORP’s common stock are within the discretion of IDACORP’s board of directors. IDACORP's board of directors reviews the dividend rate periodically to determine its appropriateness in light of IDACORP’s current and long-term financial position and results of operations, capital requirements, rating agency considerations, contractual and regulatory restrictions, legislative and regulatory developments affecting the electric utility industry in general and Idaho Power in particular, competitive conditions, and any other factors the board of directors deems relevant. The ability of IDACORP to pay dividends on its common stock is generally dependent upon dividends paid to it by its subsidiaries, primarily Idaho Power.

For additional information relating to IDACORP and Idaho Power dividends, including restrictions on IDACORP’s and Idaho Power’s payment of dividends, see Note 6 - “Common Stock” to the condensed consolidated financial statements included in this report.

Off-Balance Sheet Arrangements

IDACORP's and Idaho Power's off-balance sheet arrangements have not changed materially from those reported in MD&A in the 2022 Annual Report.

REGULATORY MATTERS

Introduction

Idaho Power is under the jurisdiction (as to rates, service, accounting, and other general matters of utility operation) of the IPUC, the OPUC, and the FERC. The IPUC and OPUC determine the rates that Idaho Power is authorized to charge to its retail customers. Idaho Power is also under the regulatory jurisdiction of the IPUC, the OPUC, and the Wyoming Public Service Commission as to the issuance of debt and equity securities. As a public utility under the Federal Power Act, Idaho Power has authority to charge market-based rates for wholesale energy sales under its FERC tariff and to provide transmission services under its OATT. Additionally, the FERC has jurisdiction over Idaho Power's sales of transmission capacity and wholesale electricity, hydropower project relicensing, and system reliability, among other items.

Idaho Power develops its regulatory filings taking into consideration short-term and long-term needs for rate relief and several other factors that can affect the structure and timing of those filings. These factors include in-service dates of major capital investments, the timing and magnitude of changes in major revenue and expense items, and customer growth rates, as well as other factors. Idaho Power's most recent general rate cases in Idaho and Oregon were filed during 2011, and in 2012, large single-issue rate cases for the Langley Gulch power plant resulted in the resetting of base rates in both Idaho and Oregon. Idaho Power also reset its base-rate power supply expenses in the Idaho jurisdiction for purposes of updating the collection of costs through retail rates in 2014 but without a resulting net increase in rates. The IPUC and OPUC have also approved base rate changes in single-issue cases subsequent to 2014.

Between general rate cases, Idaho Power relies upon customer growth, a FCA mechanism, power cost adjustment mechanisms, tariff riders, and other mechanisms to mitigate the impact of regulatory lag, which refers to the period of time between making an investment or incurring an expense and recovering that investment or expense and earning a return. Management's regulatory focus in recent years has been largely on regulatory settlement stipulations and the design of rate mechanisms. With Idaho Power’s current and anticipated significant infrastructure investments, including those that are intended to help meet projected near-term capacity deficits, Idaho Power filed a general rate case in Idaho on June 1, 2023, with a general rate case filing in Oregon likely to follow in late 2023 or 2024. Refer to Note 3 - "Regulatory Matters" to the condensed consolidated financial statements included in this report for additional information regarding the Idaho general rate case filing.

The outcomes of significant proceedings are described in part in this report and further in the 2022 Annual Report. In addition to the discussion below, which includes notable regulatory developments since the discussion of these matters in the 2022 Annual Report, refer to Note 3 - "Regulatory Matters" to the condensed consolidated financial statements included in this report for additional information relating to Idaho Power's regulatory matters and recent regulatory filings and orders.

Notable Retail Rate Changes

During 2023, Idaho Power received orders authorizing the rate changes summarized in the table below.

Description

Status

Estimated Rate Impact(1)

Notes

Power Cost Adjustment Mechanism - Idaho

New PCA rate became effective June 1, 2023

$105.1 million PCA increase for the period from June 1, 2023, to May 31, 2024

The income statement impact of revenue changes associated with the Idaho PCA mechanism is largely offset by associated increases and decreases in actual power supply costs and amortization of deferred power supply costs. The rate increase reflects higher costs associated with market energy and natural gas prices, combined with limited coal supply. The IPUC order approving the PCA increase defers collection of $95.1 million of deferred PCA costs to the subsequent annual PCA collection period.

Fixed Cost Adjustment Mechanism - Idaho

New FCA rate became effective June 1, 2023

$10.1 million FCA decrease for the period from June 1, 2023, to
May 31, 2024

The FCA is designed to remove a portion of Idaho Power’s financial disincentive to invest in energy efficiency programs by partially separating (or decoupling) the recovery of fixed costs from the volumetric kilowatt-hour (kWh) charge and instead linking it to a set amount per customer.

Annual Power Cost Update - Oregon

New APCU rate became effective June 1, 2023

$7.7 million APCU increase for the period from June 1, 2023, to May 31, 2024

The rate increase reflects continued high natural gas prices, combined with limited coal generation and increased forward market electric prices.

(1) The annual amount collected in rates is typically not recovered on a straight-line basis (i.e., 1/12th per month), and is instead recovered in proportion to retail sales volumes.

Idaho Earnings Support and Sharing from Idaho Settlement Stipulation

A May 2018 Idaho settlement stipulation related to tax reform (May 2018 Idaho Tax Reform Settlement Stipulation) is described in Note 3 - "Regulatory Matters" to the consolidated financial statements included in the 2022 Annual Report. IDACORP and Idaho Power believe that the terms allowing additional amortization of ADITC in the settlement stipulations provide the companies with a greater degree of earnings stability than would be possible without the terms of the stipulations in effect. Based on its estimate of full-year 2023 Idaho ROE, in the three and six months ended June 30, 2023, Idaho Power recorded $3.8 million and $7.5 million, respectively, in additional ADITC amortization under the May 2018 Idaho Tax Reform Settlement Stipulation. Accordingly, at June 30, 2023, $37.5 million of additional ADITC remains available for future use. Idaho Power recorded no additional ADITC amortization or provision against revenues for sharing of earnings with customers during 2022.

Change in Deferred (Accrued) Net Power Supply Costs and the Power Cost Adjustment Mechanisms

Deferred (accrued) power supply costs represent certain differences between Idaho Power's actual net power supply costs and the costs included in its retail rates, the latter being based on annual forecasts of power supply costs. Deferred (accrued) power supply costs are recorded on the balance sheets for future recovery or refund through customer rates.

Idaho Power's power cost adjustment mechanisms in its Idaho and Oregon jurisdictions address the volatility of power supply costs and provide for annual adjustments to the rates charged to retail customers. The power cost adjustment mechanisms and associated financial impacts are described in "Results of Operations" in this MD&A and in Note 3 - "Regulatory Matters" to the condensed consolidated financial statements included in this report. With the exception of power supply expenses incurred under PURPA and certain demand response program costs that are passed through to customers substantially in full, the Idaho PCA mechanism allows Idaho Power to pass through to customers 95 percent of the differences in actual net power supply expenses as compared with base net power supply expenses, whether positive or negative. Thus, the primary financial statement impact of power supply cost deferrals or accruals is that the timing of when cash is paid out for power supply expenses differs from when those costs are recovered from customers, impacting operating cash flows from year to year.

Table of Contents

The following table summarizes the change in deferred (accrued) net power supply costs during the six months ended June 30, 2023 (in millions).


	Idaho		Oregon		Total
Deferred net power supply costs at December 31, 2022	$	128.7	$	0.6	$	129.3
Current period net power supply costs deferred (accrued)	25.3		(0.3)		25.0

Deferred net power supply costs at June 30, 2023	$	126.0	$	—	$	126.0

Open Access Transmission Tariff Draft Posting

Idaho Power uses a formula rate for transmission service provided under its OATT, which provides that transmission rates will be updated annually based primarily on financial and operational data Idaho Power files with the FERC. The existing OATT rate in effect from October 1, 2022, to September 30, 2023, is $31.42 per "kW-year" based on a net annual transmission revenue requirement of $132.7 million. In May 2023, Idaho Power publicly posted its 2023 draft transmission rate, reflecting a transmission rate of $31.13 per "kW-year," to be effective for the period from October 1, 2023, to September 30, 2024. A "kW-year" is a unit of electrical capacity equivalent to 1 kilowatt of power used for 8,760 hours. Idaho Power's draft rate was based on a net annual transmission revenue requirement of $137.4 million.

Boardman-to-Hemingway Transmission Line Certificates of Public Convenience and Necessity

In June 2023, the IPUC and OPUC both issued orders granting Idaho Power's applications for certificates of public convenience and necessity authorizing construction of the Boardman-to-Hemingway 500-kV transmission line. The Boardman-to-Hemingway project is described in more detail in the "Liquidity and Capital Resources" section of this MD&A.

Oregon Resource Procurement Filing

The State of Oregon has competitive bidding rules regarding a public utility's procurement of resources. However, as allowed by the OPUC in certain cases, Idaho Power is pursuing an exception for 2023 resource needs, and plans to pursue additional exceptions to the competitive bidding rules for certain projects to meet the identified resource needs in 2024 and 2025.

In July 2023, following review by an independent evaluator appointed by the OPUC, OPUC staff, and other intervenors, the OPUC issued an order approving Idaho Power's final RFP to procure resources for its anticipated energy and capacity needs in 2026 and 2027.

Jim Bridger Power Plant Base Rate Adjustment and Recovery

In June 2022, the IPUC issued the Bridger Order approving, with modifications, Idaho Power’s amended application requesting authorization to (1) accelerate depreciation for the Jim Bridger plant, to allow the coal-related plant assets to be fully depreciated and recovered by December 31, 2030, (2) establish a balancing account to track the incremental costs, benefits, and required regulatory accounting associated with ceasing participation in coal-fired operations at the Jim Bridger plant, and (3) increase customer rates related to the associated incremental annual levelized revenue requirement. The Bridger Order and associated accounting are described in Note 3 – “Regulatory Matters” to the condensed consolidated financial statements included in this report. Idaho Power plans to cease participation in all coal-related operations at the Jim Bridger plant by 2028.

Wildfire Mitigation Cost Deferral

In June 2021, the IPUC authorized Idaho Power to defer for future amortization incremental O&M and depreciation expense of certain capital investments necessary to implement the company's WMP. The IPUC also authorized Idaho Power to record these deferred expenses as a regulatory asset until the company can request amortization of the deferred costs in a future IPUC proceeding, at which time the IPUC will have the opportunity to review actual costs and determine the amount of prudently incurred costs that Idaho Power can recover through retail rates. In its 2021 application with the IPUC, Idaho Power projected spending approximately $47 million in incremental wildfire mitigation-related O&M and roughly $35 million in wildfire mitigation system-hardening incremental capital expenditures over a five year period. The IPUC authorized a deferral period of five years, or until rates go into effect after Idaho Power's next general rate case, whichever is first. As of June 30, 2023, Idaho Power’s deferral of Idaho-jurisdiction costs related to the WMP was $39.5 million.

Table of Contents

During the 2021 and 2022 wildfire seasons, Idaho Power identified needs for expanded mitigation measures by gaining additional insights and knowledge on wildfires and wildfire mitigation activities. In October 2022, Idaho Power filed an updated WMP with the IPUC along with an application requesting authorization to defer an estimated $16 million of newly identified incremental costs expected to be incurred between 2022 and 2025 associated with expanded wildfire mitigation efforts. In March 2023, the IPUC approved Idaho Power's updated WMP and request to defer additional incremental costs.

Large Customer Rate Proceedings

Brisbie, LLC Data Center: In April 2023, the IPUC approved an arrangement, modeled after the Clean Energy Your Way program as described in the 2022 Annual Report in Part II, Item 7 - "Regulatory Matters," under which a new large load customer, Brisbie, LLC (Brisbie), a wholly-owned subsidiary of Meta Platforms, Inc., would purchase from Idaho Power energy for a new 960,000 square-foot enterprise data center. The energy to be purchased by Brisbie is anticipated to be generated by a to-be-constructed 200-MW solar facility pursuant to a long-term power purchase agreement between Idaho Power and a third party. The solar facility is scheduled to begin operating as early as March 2025.

In May 2023, the IPUC issued an order approving, with modifications, a special contract for electric service for Brisbie for the new data center. Idaho regulations require any utility customer with an average load exceeding 20 MW to enter into a special contract with its electric provider. Brisbie, in addition to its large load service requirements in excess of 20 MW, has a sustainability objective to support 100 percent of its operations with new renewable resources. Under the special contract, Idaho Power expects to procure enough renewable resources to provide Brisbie with 100 percent renewable energy on an annual basis for Brisbie’s facility. The IPUC approval of the special contract requires Idaho Power to file a modified energy services agreement and rate schedule, which Idaho Power plans to file by August 9, 2023.

Micron Dedicated Renewable Resource: In August 2022, the IPUC issued an order approving, with modifications, Idaho Power's application for a revised special contract for electric service between Idaho Power and Micron. The application was modeled after the Clean Energy Your Way program as described in the 2022 Annual Report in Part II, Item 7 - "Regulatory Matters," and included an arrangement under which Micron would purchase from Idaho Power energy generated by a to-be-constructed 40-MW solar facility pursuant to a 20-year power purchase agreement between Idaho Power and a third party. The solar facility began operating in May 2023.

In April 2023, the IPUC issued an order approving Idaho Power's compliance filing of revised electric service rates for Micron that include new energy rates that incorporate the solar generation and compensation for capacity value and excess renewable energy generation.

Lamb Weston, Inc. Special Contract: In May 2023, Idaho Power filed an application for approval of a special contract for electric service for an existing large load customer, Lamb Weston, Inc. (Lamb Weston). Idaho Power anticipates Lamb Weston's large load service requirements to exceed 20 MW and Idaho regulations require any utility customer with an average load exceeding 20 MW to enter into a special contract with its electric provider. As of the date of this report, the IPUC's decision in this matter is pending.

Western Resource Adequacy Program

In March 2023, Idaho Power filed an application with the IPUC requesting that the IPUC issue an order acknowledging the potential for long-term cost savings associated with Idaho Power's participation in the Western Resource Adequacy Program (WRAP), and allowing the company to recover WRAP-associated costs in a future rate proceeding. The WRAP is a regional reliability and compliance program being developed in western North America with the intent of providing a region-wide approach for assessing and addressing resource adequacy and reliability. Idaho Power anticipates that by participating in the WRAP it can avoid paying higher prices for energy in the wholesale markets, which savings would largely be provided to customers through Idaho Power's power cost adjustment mechanisms. In addition to the potential cost savings, Idaho Power anticipates its participation in the WRAP to provide the company with insight into regional resource adequacy and the ability to procure energy and capacity in times of extreme need. As of the date of this report, the IPUC's determination in this matter is pending.

Customer-Owned Generation Filing

Customer-owned generation enables customers to install solar panels or other on-site energy-generating resources and connect them to Idaho Power’s grid. If a customer requires more energy than its system generates, it uses energy supplied by Idaho Power’s grid and infrastructure. If a customer's system generates more energy than the customer uses, the energy is transferred

Table of Contents

to the grid and Idaho Power applies a corresponding kWh credit to the customer’s bill. In May 2018, the IPUC issued an order authorizing the creation of two new customer classes for residential and small commercial customers who install their own on-site generation, with no change to pricing or compensation. Idaho Power has initiated several cases with the IPUC related to studying the costs and benefits of customer-owned generation on Idaho Power’s system, and exploring potential modifications to the customer-owned generation pricing structure. In December 2019 and February 2020, the IPUC issued orders directing Idaho Power to (1) complete additional studies related to the costs and benefits of customer generation before changes to the compensation structure are implemented, and (2) continue to allow residential and small commercial customers with on-site generation installed prior to December 20, 2019, to be subject to the compensation and billing structure in place on that date until December 20, 2045. In December 2020, the IPUC issued an order establishing a 25-year grandfathering term for large commercial, industrial, and irrigation customers, similar to the terms approved for the residential and small commercial customer classes.

In June 2022, as directed by the IPUC, Idaho Power filed a comprehensive study on the costs and benefits of on-site generation based on the IPUC’s study framework findings and conclusions, and in December 2022, the IPUC issued an order that acknowledged the company's study and directed Idaho Power to file a new case requesting to implement changes to the structure and design of its on-site generation program. In May 2023, Idaho Power filed a new case as directed by the IPUC, requesting the IPUC to implement changes for non-grandfathered customers starting January 1, 2024, including: 1) a change from net monthly to real-time net billing, which would better measure customers’ actual reliance on the grid; 2) a change in the excess exported energy credit from a kWh credit ranging in value of 5 to 12 cents, depending on the customer class, to a time-differentiated financial bill credit ranging from approximately 5 to 20 cents per kWh that would be updated annually; and 3) a modification to the eligibility cap for large commercial, industrial, and irrigation customers. As of the date of this report, the IPUC's determination in this matter is pending.

Renewable and Other Energy Contracts

Idaho Power has contracts for the purchase of electricity produced by third-party owned generation facilities, most of which produce energy with the use of renewable generation sources such as wind, solar, biomass, small hydropower, and geothermal. The majority of these contracts are entered into as mandatory purchases under PURPA. As of June 30, 2023, Idaho Power had contracts to purchase energy from 129 online PURPA projects. An additional five contracts are with online non-PURPA projects, including the Elkhorn Valley wind project with a 101-MW nameplate capacity, the Jackpot Solar project with a 120-MW nameplate capacity, and the Black Mesa solar project with a 40-MW nameplate capacity.

The following table sets forth, as of June 30, 2023, the resource type and nameplate capacity of Idaho Power's signed agreements for power purchases from PURPA and non-PURPA generating facilities. These agreements have original contract terms ranging from one to 35 years.


Resource Type	Online (MW)	Under Contract but not yet Online (MW)	Total Projects under Contract (MW)
PURPA:
Wind	625	—	625
Solar	316	74	390
Hydropower	150	1	151
Other	44	—	44
Total	1,135	75	1,210
Non-PURPA:
Wind	101	—	101
Geothermal	35	—	35
Solar	160	300	460
Total	296	300	596

The PURPA-qualifying facility projects not yet online include one hydropower project that is scheduled to be online in 2023, and three PURPA-qualifying facility solar projects expected to be online in 2024. Two non-PURPA solar projects, for 100 MW and 200 MW, are scheduled to be online in 2024 and 2025, respectively. In February 2023, Idaho Power filed an application with the IPUC requesting an order approving the agreement with the 100 MW solar project, and granting Idaho Power a

Table of Contents

certificate of public convenience and necessity to acquire a total of 72 MW of new dispatchable energy storage to meet identified capacity deficiencies in 2024. As of the date of this report, the IPUC's determination in this matter is pending.

In April 2023, Idaho Power entered into an agreement, pending regulatory approval, with a 150-MW battery storage facility, scheduled to be online in June 2025. Under the agreement, the facility would provide 150 MW of capacity on Idaho Power’s system for a period of 20 years, and Idaho Power would have the exclusive right to dispatch and use the charging and discharging energy in exchange for a monthly payment. In May 2023, Idaho Power filed an application with the IPUC requesting an order approving the agreement and acknowledging the lease accounting necessary to facilitate the transaction, and that the resulting expenses are prudently incurred for ratemaking purposes. As part of that same application, Idaho Power requested the IPUC issue an order granting Idaho Power a certificate of public convenience and necessity to acquire a total of 101 MW of new dispatchable energy storage to meet identified capacity deficiencies in both 2024 and 2025. As of the date of this report, the IPUC's decision in these matters is pending.

Relicensing of Hydropower Projects

HCC Relicensing: In connection with Idaho Power's major efforts to relicense the HCC, Idaho Power's largest hydropower complex, as described in more detail in the 2022 Annual Report in Part II, Item 7 - "Regulatory Matters," Idaho Power submitted to the FERC in July 2020 its supplement to the final license application. The supplement incorporated the settlement agreement reached between Idaho and Oregon on the Clean Water Act (CWA) Section 401 certifications, which precipitated the states issuing final CWA Section 401 certifications in May 2019. The states of Idaho and Oregon also submitted the CWA Section 401 certifications to the FERC as part of the relicensing process. The supplement included feedback on proposed modifications of the 2007 final environmental impact statement (EIS) for the HCC, as well as an updated cost analysis of the HCC and a request that the FERC issue a 50-year license and initiate a supplemental National Environmental Policy Act (NEPA) process at the FERC. Idaho Power prepared draft biological assessments in consultation with the U.S. Fish and Wildlife Service (USFWS) and the National Marine Fisheries Service (NMFS) and filed those with the FERC in October 2020. The draft biological assessments provide information to the USFWS and the NMFS that is necessary to issue their biological opinion as required under the Endangered Species Act (ESA). Since December 2020, Idaho Power has responded to sixteen additional information requests issued by the FERC staff to aid in the FERC's analysis.

In June 2022, the FERC issued a Notice of Intent (NOI) to prepare a supplemental EIS in accordance with NEPA. The FERC indicated that the supplemental EIS would address the new and revised measures proposed by the CWA 401 certification settlement, the conditions contained in the Oregon and Idaho water quality certifications, and the information provided in the draft biological assessments. The FERC also reinitiated informal consultation with the USFWS and the NMFS under section 7 of the ESA. In the notice of intent, the FERC predicted that the draft supplemental EIS would be published in June 2023 and the final supplemental EIS in December 2023; an updated NOI has not yet been issued.

Idaho Power estimates that the annual costs it will incur to obtain a new long-term license for the HCC, including AFUDC, are likely to range from $30 million to $40 million until issuance of the license. Subsequent to the issuance of a new license, Idaho Power expects to incur increased annual operating and maintenance costs to comply with the requirements of any new license and would seek to recover those increased costs through regulatory proceedings. Although Idaho Power is unable to predict the exact timing that the FERC will issue a new license or the ultimate capital investment and ongoing operating and maintenance costs Idaho Power will incur in complying with any new license, as of the date of this report, Idaho Power believes issuance of a new HCC license by the FERC will be in 2024 or thereafter.

Relicensing costs for Idaho Power's hydropower projects are recorded as construction work in progress until new multi-year licenses are issued by the FERC, at which time the charges are transferred to electric plant in service. Idaho Power expects to seek recovery of relicensing costs and costs related to a new long-term license through the regulatory process. Relicensing costs of $441 million (including AFUDC) for the HCC were included in construction work in progress at June 30, 2023. As of the date of this report, the IPUC authorizes Idaho Power to include in its Idaho jurisdiction rates $8.8 million of AFUDC annually relating to the HCC relicensing project. Collecting these amounts currently will reduce future collections when HCC relicensing costs are approved for recovery in base rates. As of June 30, 2023, Idaho Power's regulatory liability for collection of AFUDC relating to the HCC was approximately $218 million.

American Falls Relicensing: In April 2020, the FERC formally initiated the relicensing of the American Falls hydropower facility, which is Idaho Power's largest hydropower facility outside of the HCC, with a generating capacity of 92.3 MW. Idaho Power owns the generation facility but not the structural dam itself, which is owned by the U.S. Bureau of Reclamation. The FERC recognized Idaho Power’s pre-application document, including a proposed process plan and schedule, and recognized Idaho Power’s intent to file an application for a license. In February 2023, following the public comment period on its draft

Table of Contents

license application, Idaho Power filed a final license application with the FERC. The relicensing has begun the process of informal ESA Section 7 consultation with the USFWS and Section 106 of the National Historic Preservation Act consultation with the Idaho State Historic Preservation Office. American Falls' current license expires in 2025, and as of the date of this report, Idaho Power expects the FERC to issue a new license for this facility concurrent with or prior to the existing license expiration.

ENVIRONMENTAL MATTERS

Overview

Idaho Power is subject to a broad range of federal, state, regional, and local laws and regulations designed to protect, restore, and enhance the environment, including the Clean Air Act (CAA), the CWA, the Resource Conservation and Recovery Act, the Toxic Substances Control Act, the Comprehensive Environmental Response, Compensation and Liability Act, and the ESA, among other laws. These laws are administered by a number of federal, state, and local agencies. In addition to imposing continuing compliance obligations and associated costs, these laws and regulations provide authority to regulators to levy substantial penalties for noncompliance, injunctive relief, and other sanctions. Idaho Power's two co-owned coal-fired power plants and three wholly-owned natural gas-fired combustion turbine power plants are subject to many of these regulations. Idaho Power's 17 hydropower projects are also subject to a number of water discharge standards and other environmental requirements.

Compliance with current and future environmental laws and regulations may:

•increase the operating costs of generating plants;

•increase the construction costs and lead time for new facilities;

•require the modification of existing generating plants, which could result in additional costs;

•require the curtailment, fuel-switching, or shut-down of existing generating plants;

•reduce the output from current generating facilities; or

•require the acquisition of alternative sources of energy or storage technology, increased transmission wheeling, or construction of additional generating facilities, which could result in higher costs.

Current and future environmental laws and regulations could significantly increase the cost of operating fossil fuel-fired generation plants and constructing new generation and transmission facilities, in large part through the substantial cost of permitting activities and the required installation of additional pollution control devices. In many parts of the United States, some higher-cost, high-emission coal-fired plants have ceased operation or the plant owners have announced a near-term cessation of operation, as the cost of compliance makes the plants uneconomical to operate. The decision to cease operation of the Boardman power plant in 2020 was based in part on the significant cost of compliance with environmental laws and regulations. The decision to pursue an end to participation in coal-fired operations at the Valmy plant was also based primarily on the economics of continuing coal-fired generation at the plant. Beyond increasing costs generally, these environmental laws and regulations could affect IDACORP's and Idaho Power's results of operations and financial condition if the costs associated with these environmental requirements and early plant retirements cannot be fully recovered in rates on a timely basis.

Part I - "Business - Utility Operations - Environmental Regulation and Costs" in the 2022 Annual Report, includes a summary of Idaho Power's expected capital and operating expenditures for environmental matters during the period from 2023 to 2025. Given the uncertainty of future environmental regulations and technological advances, there is uncertainty around near-term estimates, and Idaho Power is also unable to predict its environmental-related expenditures beyond 2025, though they could be substantial.

A summary of notable environmental matters (including conditions and events associated with climate change) impacting, or expected to potentially impact, IDACORP and Idaho Power is included in Part II, Item 7 - "MD&A - Environmental Issues" and "MD&A - Liquidity and Capital Resources - Capital Requirements - Environmental Regulation Costs" in the 2022 Annual Report. Recent developments in certain environmental matters relevant to Idaho Power are described below.

Endangered Species Act Matters

Changes to the Endangered Species Act: The listing of a species, or changes to the critical habitat designations, of fish, wildlife, or plants as threatened or endangered under the ESA, and the associated mitigation policies, may have an adverse impact on Idaho Power's ability to construct power supply, transmission, or distribution facilities or relicense or operate its hydropower facilities. In May 2023, the USFWS published a revised Mitigation Policy and a revised ESA Compensatory Mitigation Policy (Revised Policies) which together establish fundamental mitigation principles and compensatory mitigation standards and application guidance through implementation of the ESA. The Revised Policies scale back the mitigation goal from the previous policies by including a nexus and proportionality principle to reinforce that government-required mitigation measures must have a clear connection with the anticipated effects of the proposed land use. As of the date of this report, Idaho Power is uncertain to what extent the Revised Policies may impact its obligations in permitting infrastructure, including relicensing its hydroelectric facilities, and transmission lines.

Clean Air Act Matters

Good Neighbor Plan: In June 2023, the U.S. Environmental Protection Agency (EPA) published the final rule under the CAA called the Federal "Good Neighbor Plan" for the 2015 Ozone National Ambient Air Quality Standards (Good Neighbor Plan), to be effective August 4, 2023. The Good Neighbor Plan establishes NOx emissions budgets requiring fossil fuel-fired power plants to participate in an allowance-based ozone season trading program. The EPA's final rule temporarily excludes power plants located in Wyoming, while the EPA reevaluates the proposed disapproval of the Wyoming state implementation plan (SIP). Refer to Part II, Item 7 - "MD&A - Environmental Issues" in the 2022 Annual Report for more information on SIPs.

In July 2023, the Ninth Circuit Court of Appeals issued a stay halting application of the Good Neighbor Plan in Nevada pending a hearing on the merits of an appeal challenging the EPA's disapproval of Nevada's SIP. As of the date of this report, Idaho Power continues to evaluate the specific impacts the Good Neighbor Plan could have on its operations at the Valmy and Jim Bridger plants. If the Good Neighbor Plan is implemented in Nevada and Wyoming, Idaho Power anticipates under certain conditions it could reduce the ability to use the full available output at the Valmy and Jim Bridger plants.

Regulation of Greenhouse Gas Emissions: In May 2023, the EPA released a proposed rule under Section 111 of the CAA to regulate greenhouse gas emissions from fossil fuel-fired power plants. The proposed rule would impose significant GHG emissions reductions on new and existing natural gas-fired generating units and coal plants expected to be operational in 2040 and beyond. The proposed rule would require states to submit plans to the EPA to implement standards for existing sources within 24 months of the effective date of the emission guidelines. As of the date of this report, Idaho Power continues to evaluate the specific impacts the proposed rule could have on its operations at its three natural gas facilities, as well as the Valmy and Jim Bridger plants. If the proposed rule is implemented, Idaho Power anticipates that the GHG emissions reductions may under certain circumstances only be achievable by reducing unit runtimes.

Clean Water Act Matters

Definition of “Waters of the United States” Under the CWA: Since 2015, the EPA and U.S. Army Corps of Engineers have been attempting to define the scope of "waters of the United States" (WOTUS) under the CWA. The WOTUS definition is fundamental to the application of the CWA because only those bodies of water designated as WOTUS are protected from unlawful discharge of pollutants under the CWA.

In May 2023, the U.S. Supreme Court issued a decision defining WOTUS under the CWA and providing nationwide clarity of the federal government’s jurisdiction over WOTUS. The decision restricts the federal government's ability to regulate wetlands that do not have a continuous surface connection with a navigable water. While not addressed in the opinion, ephemeral streams and other water bodies that are not relatively permanent would also not be jurisdictional under the May 2023 decision. The current presidential administration is developing a rule to amend the previous rule published in January 2023, consistent with the U.S. Supreme Court's decision. Because the new definition does not alter how the CWA applies to most of Idaho Power's facilities, including its hydropower plants, Idaho Power does not expect the new rule to materially impact Idaho Power's operations or financial condition.

CWA Permitting: Idaho Power's hydropower generation facilities are subject to compliance and permitting obligations under the CWA. Idaho Power has been engaged for several years with the EPA, and is now engaged with the Idaho Department of Environmental Quality (IDEQ), regarding Idaho Power's CWA permitting obligations and compliance status for those facilities. Idaho Power has in the past, and expects in the future, to incur costs associated with those permitting and compliance obligations, but as of the date of this report, Idaho Power is unable to estimate with any reasonable certainty those costs. Idaho

Table of Contents

Power also expects to incur additional costs associated with the relicensing of its hydroelectric facilities, as discussed elsewhere in this report.

In June 2022, Idaho Power and the IDEQ entered into a consent judgment in the district courts for the third, fourth, fifth, and sixth judicial districts of the State of Idaho to resolve a National Pollutant Discharge Elimination System permitting issue related to 15 of Idaho Power’s hydropower projects that required Idaho Power to pay a $1.1 million fine, implement interim measures for compliance, and ultimately submit applications for new permits at each of the dams subject to the consent judgment. Due to a misinterpretation of law, the EPA cancelled water discharge permits in the mid-1990’s, and Idaho Power recently determined that those permits are applicable for operation of the dams. However, Idaho Power believes that the dams would have been in compliance with the earlier permits had they remained in place. As of the date of this report, Idaho Power has submitted new permit applications for nine of the dams and anticipates completing all submissions by June 2024.

OTHER MATTERS

Critical Accounting Policies and Estimates

IDACORP's and Idaho Power's discussion and analysis of their financial condition and results of operations are based upon their condensed consolidated financial statements, which have been prepared in accordance with generally accepted accounting principles. The preparation of these financial statements requires IDACORP and Idaho Power to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues, and expenses and related disclosure of contingent assets and liabilities. On an ongoing basis, IDACORP and Idaho Power evaluate these estimates, including those estimates related to rate regulation, retirement benefits, contingencies, asset impairment, income taxes, unbilled revenues, and bad debt. These estimates are based on historical experience and on other assumptions and factors that are believed to be reasonable under the circumstances, and are the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. IDACORP and Idaho Power, based on their ongoing reviews, make adjustments when facts and circumstances dictate.

IDACORP’s and Idaho Power’s critical accounting policies are reviewed by the audit committees of the boards of directors. These policies have not changed materially from the discussion of those policies included under "Critical Accounting Policies and Estimates" in the 2022 Annual Report.

Recently Issued Accounting Pronouncements

There have been no recently issued accounting pronouncements that have had or are expected to have a material impact on IDACORP's or Idaho Power's condensed consolidated financial statements.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

IDACORP is exposed to market risks, including changes in interest rates, changes in commodity prices, credit risk, and equity price risk. The following discussion summarizes material changes in these risks since December 31, 2022, and the financial instruments, derivative instruments, and derivative commodity instruments sensitive to changes in interest rates, commodity prices, and equity prices that were held at June 30, 2023. IDACORP has not entered into any of these market-risk-sensitive instruments for trading purposes.

Interest Rate Risk

IDACORP manages interest expense and short- and long-term liquidity through a combination of fixed rate and variable rate debt. Generally, the amount of each type of debt is managed through market issuance, but interest rate swap and cap agreements with highly-rated financial institutions may be used to achieve the desired combination.

Variable Rate Debt: As of June 30, 2023, IDACORP had no net variable rate debt, as the carrying value of short-term investments exceeded the carrying value of outstanding variable rate debt.

Fixed Rate Debt: As of June 30, 2023, IDACORP had $2.5 billion in fixed rate debt, with a fair value of approximately $2.2 billion. These instruments are fixed rate and, therefore, do not expose the companies to a loss in earnings due to changes in market interest rates. However, the fair value of these instruments would increase by approximately $278 million if market interest rates were to decline by one percentage point from their June 30, 2023, levels.

Table of Contents

Commodity Price Risk

IDACORP's exposure to changes in commodity prices is related to Idaho Power's ongoing utility operations that produce electricity to meet the demand of its retail electric customers. These changes in commodity prices are mitigated in large part by Idaho Power's Idaho and Oregon power cost adjustment mechanisms. To supplement its supply resources and balance its supply of power with the demand of its retail customers, Idaho Power participates in the wholesale marketplace. IDACORP's commodity price risk as of June 30, 2023, had not changed materially from that reported in Item 7A of IDACORP's and Idaho Power's Annual Report on Form 10-K for the year ended December 31, 2022 (2022 Annual Report). Information regarding Idaho Power’s use of derivative instruments to manage commodity price risk can be found in Note 11 - "Derivative Financial Instruments" to the condensed consolidated financial statements included in this report.

Credit Risk

IDACORP is subject to credit risk based on Idaho Power's activity with market counterparties. Idaho Power is exposed to this risk to the extent that a counterparty may fail to fulfill a contractual obligation to provide energy, purchase energy, or complete financial settlement for market activities. Idaho Power mitigates this exposure by actively establishing credit limits; measuring, monitoring, and reporting credit risk; using appropriate contractual arrangements; and transferring credit risk through the use of financial guarantees, cash, or letters of credit. Idaho Power maintains a current list of acceptable counterparties and credit limits.

The use of performance assurance collateral in the form of cash, letters of credit, or guarantees is common industry practice. Idaho Power maintains margin agreements relating to its wholesale commodity contracts that allow performance assurance collateral to be requested of and/or posted with certain counterparties. As of June 30, 2023, Idaho Power posted $44 million performance assurance collateral related to these contracts. Should Idaho Power experience a reduction in its credit rating on Idaho Power's unsecured debt to below investment grade, Idaho Power could be subject to requests by its wholesale counterparties to post additional performance assurance collateral. Counterparties to derivative instruments and other forward contracts could request immediate payment or demand immediate ongoing full daily collateralization on derivative instruments and contracts in net liability positions. Based upon Idaho Power's energy and fuel portfolio and market conditions as of June 30, 2023, the amount of collateral that could be requested upon a downgrade to below investment grade was approximately $18.7 million. To minimize capital requirements, Idaho Power actively monitors the portfolio exposure and the potential exposure to additional requests for performance assurance collateral calls through sensitivity analysis.

IDACORP's credit risk related to uncollectible accounts, net of amounts reserved, as of June 30, 2023, had not changed materially from that reported in Item 7A of the 2022 Annual Report, except as disclosed in Note 4 - "Revenues" to the condensed consolidated financial statements included in this report. Additional information regarding Idaho Power’s management of credit risk and credit contingent features can be found in Note 11 - "Derivative Financial Instruments" to the condensed consolidated financial statements included in this report.

Equity Price Risk

IDACORP is exposed to price fluctuations in equity markets, primarily through Idaho Power's defined benefit pension plan assets, a mine reclamation trust fund owned by an equity-method investment of Idaho Power, and other equity security investments at Idaho Power. The equity securities held by the pension plan and in such accounts are diversified to achieve broad market participation and reduce the impact of any single investment, sector, or geographic region. Idaho Power has established asset allocation targets for the pension plan holdings, which are described in Note 11 - "Benefit Plans" to the consolidated financial statements included in the 2022 Annual Report.
