Alabama Power, as agent for SEGCO, initially indicated plans to retire Plant Gaston Units 1 through 4 (1,000 MWs) by December 31, 2028. However, upon further analysis, Alabama Power, in conjunction with Georgia Power, now expects to operate Plant Gaston Units 1 through 4 through December 31, 2034. On September 17, 2025, Alabama Power submitted an Automatic Transfer Notice of Planned Participation (NOPP) authorizing compliance with the 2020 ELG rule generally applicable limits for bottom ash transport water for Plant Gaston Units 1 through 4 by December 31, 2025.

On July 15, 2025, the Georgia PSC approved Georgia Power's request in the 2025 IRP to extend the operation of Plant Scherer Unit 3 (614 MWs based on 75% ownership) through at least December 31, 2035 and Plant Gaston Units 1 through 4 (500 MWs based on 50% ownership through SEGCO) through December 31, 2034. In addition, the approved 2025 IRP assumes operation of Plant Bowen Units 1 and 2 (1,400 MWs) through at least December 31, 2035 and does not impact the scrubber wastewater compliance strategy for Plant Bowen as the scrubber wastewater system is a common environmental control for all four generating units. Georgia Power expects to submit a NOPP indicating plans to pursue compliance with the 2020 ELG rule for Plant Scherer Unit 3 through the voluntary incentive program by December 31, 2028.
