Commitments and Contingencies Disclosure [Abstract]
Spent Nuclear Fuel Storage Costs	Spent Nuclear Fuel Storage Costs. Contracts with the U.S. Department of Energy have been executed to provide for the permanent disposal of spent nuclear fuel produced at Plants Hatch and Vogtle Units No. 1 and No. 2. The Department of Energy failed to begin disposing of spent fuel in January 1998 as required by the contracts, and Georgia Power, as agent for the co-owners of the plants, is pursuing legal remedies against the Department of Energy for breach of contract. On September 5, 2025, Georgia Power filed their fifth round of lawsuits against the U.S. government in the Court of Federal Claims, seeking damages for the costs of continuing to store spent nuclear fuel at Plant Hatch and Plant Vogtle Units No. 1 and No. 2 for the period from January 1, 2020 through December 31, 2024. Damages will continue to accumulate until the issue is resolved, the U.S. government disposes of Georgia Power's spent nuclear fuel pursuant to its contractual obligations, or alternative storage is otherwise provided. No amounts have been recognized in our consolidated financial statements as of June 30, 2026 for any potential recoveries from the pending lawsuits. The final outcome of this matter cannot be determined at this time. Both Plants Hatch and Vogtle have on-site dry spent storage facilities in operation. We expect that facilities at both plants can be expanded to accommodate spent fuel through the expected life of each plant. For additional information regarding nuclear fuel costs, see Note 1g in our 2025 Form 10-K.
