Filed May 19, 2025For Securities:SOSOJESOJFSOJCSOJDSOMN

Summary

Southern Company's subsidiary, Georgia Power, has entered into a settlement agreement with the Georgia Public Service Commission (PSC) Public Interest Advocacy Staff that, if approved by the PSC, will extend the company's alternate rate plan (ARP) through December 31, 2028. This agreement defers rate adjustments for 2026, 2027, and 2028, with storm damage costs to be addressed in a separate regulatory proceeding. The settlement maintains Georgia Power's retail return on equity (ROE) set point at 10.50% and equity ratio at 56%, with a continuing ROE range of 9.50% to 11.90%. Key modifications include the separate recovery of storm damage costs incurred through 2025, the continued amortization of regulatory assets, liabilities, and deferred tax credits, and a change in depreciation/amortization periods for certain generating assets to 13 years. Earnings above the ROE range will continue to be shared with customers, while shortfalls may trigger a request for an Interim Cost Recovery tariff.

Frequently Asked Questions

The settlement defers base rate adjustments for 2026, 2027, and 2028. Any recovery of storm damage costs incurred through the end of 2025 will be handled in a separate regulatory proceeding and will be the primary potential adjustment to rates during this period.

If Georgia Power's retail earnings exceed the 9.50% to 11.90% ROE range, 40% of the excess earnings will be applied to regulatory assets, 40% will be refunded to customers, and 20% will be retained by Georgia Power.

If Georgia Power projects earnings below the lower end of the ROE range, it may petition the PSC for an Interim Cost Recovery (ICR) tariff to adjust rates, or it may be required to file a full base rate case.

Deferred Investment Tax Credits (ITCs) and Production Tax Credits (PTCs) will be amortized over the extended period. Certain ITCs generated during the ARP Extension Period will be amortized over five years, with additional amounts deferred. Sixty percent of PTC benefits generated will be credited to income tax expense, and the remaining forty percent will be deferred. Additionally, the depreciation and amortization period for certain generating plants and retired plant net book values will be extended to 13 years.

The Georgia PSC is scheduled to vote on the settlement agreement by July 1, 2025. If the settlement is not approved, Georgia Power will be required to file its next base rate case by July 1, 2025.
