Georgia Power

Plant Vogtle Units 3 and 4 Construction and Start-Up Status

Georgia Power placed Plant Vogtle Units 3 and 4 in service on July 31, 2023 and April 29, 2024, respectively. During the second quarter 2024, following Unit 4's in-service date, Southern Nuclear evaluated the remaining expected site demobilization costs and other contractor obligations and reduced the remaining estimate to complete forecast by approximately $21 million, including the impact of joint owner cost-sharing. Accordingly, Georgia Power recorded a pre-tax credit to income of approximately $21 million ($16 million after tax), including the joint owner agreement impacts, in the second quarter 2024 to recognize forecasted capital costs previously charged to income. Georgia Power's share of the remaining project capital cost forecast, including completion of site demobilization and remaining contractor obligations, is $69 million. See Note 2 to the financial statements under "Georgia Power – Nuclear Construction – Cost and Schedule" for additional information.

Plant Vogtle Units 3 and 4 Regulatory Matters

In December 2023, the Georgia PSC approved Georgia Power's application to adjust rates to include reasonable and prudent Plant Vogtle Units 3 and 4 costs as modified by the related stipulation (Prudency Stipulation) among Georgia Power, the staff of the Georgia PSC, and certain intervenors.

Georgia Power included in retail rate base $5.462 billion of construction and capital costs as well as $647 million of associated retail rate base items effective with the April 29, 2024 in-service date for Unit 4, pursuant to the approved Prudency Stipulation. Annual retail base revenues increased approximately $730 million and the average retail base rates were adjusted by approximately 5% (net of the elimination of the NCCR tariff described below) effective May 1, 2024.

Further, as included in the approved Prudency Stipulation, since commercial operation for Unit 4 was not achieved by March 31, 2024, Georgia Power's ROE used to determine the NCCR tariff and calculate AFUDC was reduced to zero effective April
