Government Assistance [Abstract]
Government Assistance	Government Assistance Beginning in 2024, our nuclear units are eligible for a PTC extending through 2032. The nuclear PTC provides a transferable credit up to $15 per MWh (a base credit of $3 per MWh with a five times multiplier provided certain prevailing wage requirements are met) and is subject to phase-out when annual gross receipts are between $25.00 per MWh and $43.75 per MWh. We evaluated and expect to meet the annual prevailing wage requirements at all of our nuclear units and are eligible for the five times multiplier. Both the amount of the PTC and the gross receipts thresholds adjust for inflation annually through the duration of the program based on the GDP price deflator for the preceding calendar year. We expect the inflation factor for 2025 to be published in the second or third quarter of 2025. The benefits of the PTC may be realized through a credit against our federal income taxes or transferred via sale to an unrelated party. For the three months ended March 31, 2025, we did not record a nuclear PTC benefit as the estimate of full year gross receipts exceeds the phase-out amount for annual gross receipts per MWh for all units. For the three months ended March 31, 2024, our Consolidated Statements of Operations and Comprehensive Income included a nuclear PTC benefit in Operating revenues of approximately $304 million. Our estimates require the exercise of judgment in determining the amount of nuclear PTC expected for each of our nuclear units. The nuclear PTC continues to be the subject of additional guidance, which may be issued from the U.S. Treasury and IRS sometime in 2025, and may materially impact the total amount of the benefits we receive. Nuclear PTCs are initially recorded within Other deferred debits and other assets within the Consolidated Balance Sheets and reclassified as a reduction to Accounts payable and accrued expenses when used to reduce our federal income tax payable, or an increase in Cash and cash equivalents or Other current assets when sold, depending on the specific payment terms of each contract. Cash received in the first quarter of 2025 on sale agreements executed in 2024 was approximately $95 million. There were no agreements for sales of nuclear PTCs executed in the first quarter of 2025 or 2024. As of March 31, 2025, our Consolidated Balance Sheets reflect approximately $130 million of nuclear PTCs within Other deferred debits and other assets. As of December 31, 2024, our Consolidated Balance Sheets reflected $185 million of estimated nuclear PTCs within Other deferred debits and other assets, and $95 million within Other current assets. Additionally, as of March 31, 2025 and December 31, 2024, we recognized a reduction to Accounts payable and accrued expenses in our Consolidated Balance Sheets of $40 million and $150 million, respectively, for estimated nuclear PTCs that we have utilized as a credit against our current federal income taxes payable. Many of the state-sponsored programs providing compensation for the emissions-free attributes of generation from certain of our nuclear units include contractual or other provisions that require us to refund that compensation up to the amount of the nuclear PTC received or pass through the entirety of the nuclear PTC received. As of March 31, 2025 and December 31, 2024, we have recognized approximately $1,030 million of estimated payables within Other deferred credits and other liabilities, Accounts payable and accrued expenses or as offsets to Customer accounts receivable in our Consolidated Balance Sheets associated with programs requiring refunds or pass through of the nuclear PTC. We recognized a benefit to net operating revenue of approximately $110 million and $69 million (pre-tax) for the three months ended March 31, 2025 and 2024, respectively, associated with these programs in our Consolidated Statements of Operations and Comprehensive Income. As with the actual amount of the nuclear PTC earned, which cannot be determined until after the end of the calendar year, any change resulting from additional guidance received may materially impact amounts due under state-sponsored programs.
