| Named Executive Officers, Footnote [Text Block] | The dollar amounts reported in column (b) are the amounts of total compensation reported for Mr. Dominguez | |
| Peer Group Issuers, Footnote [Text Block] | The peer group used for this purpose is the following published industry index: S&P 500 Industrials. | |
| PEO Total Compensation Amount | $ 10,439,082 | [1] |
| PEO Actually Paid Compensation Amount | 23,640,761 | [2] |
| Non-PEO NEO Average Total Compensation Amount | 4,078,360 | [3] |
| Non-PEO NEO Average Compensation Actually Paid Amount | $ 11,598,514 | [4] |
| Adjustment to Non-PEO NEO Compensation Footnote [Text Block] | The dollar amounts reported in column (d) represent the average of the amounts reported for the company’s named executive officers (NEOs) as a group (excluding Mr. Dominguez) in the “Total” column of the Summary Compensation Table above in each applicable year. The names of each of the NEOs (excluding Mr. Dominguez) included for purposes of calculating the average amounts in 2022 for Messrs. Eggers, Hanson, Koehler, and McHugh. | |
| Compensation Actually Paid vs. Total Shareholder Return [Text Block] | Compensation Actually Paid and Cumulative Total Shareholder Return (TSR) As demonstrated by the graph below, the amount of compensation actually paid to Mr. Dominguez and the average amount of compensation actually paid to the company’s NEOs as a group (excluding Mr. Dominguez) is aligned with the company’s TSR for the year presented in the table. The alignment of compensation actually paid with the company’s cumulative TSR over the period presented is a result of having a significant portion of the compensation actually paid to Mr. Dominguez and to the other NEOs comprised of equity awards. As described in more detail in the section “Compensation Discussion and Analysis” above, the company targets that approximately 74% of the value of total compensation awarded to the CEO and 56% of the value of total compensation awarded to other NEOs be comprised of equity awards, including restricted stock units and performance-based restricted stock units. | |
| Compensation Actually Paid vs. Net Income [Text Block] | Compensation Actually Paid, Net Income and Adjusted EBITDA As demonstrated by the tables below, the amount of compensation actually paid to Mr. Dominguez and the average amount of compensation actually paid to our NEOs as a group (excluding Mr. Dominguez) is generally aligned with our net income and Adjusted EBITDA performance as reported in the 2022 Annual Report on Form 10-K. While we do not use net income as a performance measure in the overall executive compensation program, the measure of net income is the GAAP measure used to reconcile to the Adjusted EBITDA measure, which the company uses when setting goals in our short-term incentive compensation program. Adjusted EBITDA is defined as net income plus non-cash interest expense, depreciation and amortization, interest and other income, income tax provision, loss (gain) on the extinguishment of debts, stock-based compensation expense and restructuring or other unusual charges. While the company uses numerous financial and non- financial performance measures for the purpose of evaluating performance for the company’s compensation programs, the company has determined that Adjusted EBITDA is the financial performance measure that represents the most important performance measure (that is not otherwise required to be disclosed in the table) used by the company to link compensation actually paid to the company’s NEOs, for the most recently completed fiscal year, to company performance. As described in more detail in the “Compensation Discussion and Analysis” section above, we target that approximately 15% of the value of total compensation awarded to the CEO and 20% of the value of total compensation awarded to other NEOs be comprised of amounts determined under our short-term incentive compensation program. | |
| Total Shareholder Return Vs Peer Group [Text Block] | Cumulative TSR of Constellation and Cumulative TSR of the Peer Group As demonstrated by the graph below, Constellation’s cumulative TSR over the year since becoming a publicly traded company presented in the table was 75%, while the cumulative TSR of the peer group presented for this purpose, the S&P 500 Industrials, was negative 2% over the year presented in the table. Constellation’s cumulative TSR outperformed the S&P Industrials, during the year presented in the table, representing the company’s superior financial performance as compared to the companies comprising the S&P 500 Industrials peer group. For more information regarding our performance and the companies that the Compensation Committee considers when determining compensation, refer to the “Compensation Discussion and Analysis” section above. | |
| Tabular List [Table Text Block] | As described in greater detail in “Compensation Discussion and Analysis” above, the company’s executive compensation program reflects an alignment to shareholder interest. The metrics used for both our long-term and short-term incentive awards are selected based on an objective of incentivizing our NEOs to increase the value of our enterprise for our shareholders. The most important financial performance measures used by the company to link executive compensation actually paid to the NEOs, for the most recently completed fiscal year, to the company’s performance are as follows: • Adjusted EBITDA • Free Cash Flow before Growth • CFO/Debt • Fleetwide Capacity Factor • Dispatch Match • Customer Satisfaction | |
