Mergers, Acquisitions, and Dispositions [Abstract]
Mergers, Acquisitions, and Dispositions	Mergers, Acquisitions, and Dispositions Acquisition of Joint Ownership in South Texas Project In November 2023, we completed the acquisition of NRG South Texas LP (renamed and converted as Constellation South Texas, LLC), which owns a 44% undivided ownership interest in the jointly owned STP, a 2,645 MW, dual-unit nuclear plant located in Bay City, Texas. The net cash paid was $1.65 billion, after certain purchase price adjustments. Other owners include City Public Service Board of San Antonio (CPS, 40%) and the City of Austin, Texas (Austin, 16%). See Note 2 — Mergers, Acquisitions, and Dispositions of our 2023 Form 10-K for additional information. In May 2024, we executed a settlement agreement with all parties (CPS/City of San Antonio, Austin, and NRG), resolving all litigation involving our purchase of the ownership interest in STP, which was initiated by CPS and Austin in Texas state court and before the NRC. The terms of the settlement include us selling a 2% ownership interest in STP to CPS at the same price and terms that we paid NRG for our 44% interest, subject to regulatory approvals from the NRC and the Public Utility Commission of Texas. Pursuant to the settlement, CPS and Austin filed Notices of Dismissal with Prejudice with the Court, which ends the litigation, and likewise withdrew their pending objections to the sale with the NRC. As a result of the settlement, we have reflected assets and liabilities associated with a 2% undivided ownership interest in STP as held for sale. The held for sale amounts are included in the Other current assets and Other current liabilities balances in the Consolidated Balance Sheets as of September 30, 2024. Closing is expected to occur within the first half of 2025. Upon closing of the sale, we and CPS will each own a 42% interest in STP, and Austin’s interest will remain at 16%. The terms of settlement are not expected to have a material impact on our consolidated financial statements.
