Business Context and Reporting Period
This Form 8-K is a joint filing by The Southern Company and Georgia Power Company dated May 19, 2025. The report details a settlement agreement reached between Georgia Power and the Georgia Public Service Commission (PSC) regarding the extension of the company's Alternate Rate Plan (ARP).
Key Financial Metrics and Terms
The filing outlines specific financial parameters for the proposed rate plan extension through December 31, 2028:
- Rate Stability: Base retail rates will remain unchanged for 2026, 2027, and 2028, excluding storm damage costs.
- Return on Equity (ROE): The set point remains at 10.50% with an approved range of 9.50% to 11.90%.
- Equity Ratio: Maintained at 56%.
- Storm Cost Recovery: Reasonable and prudent storm costs incurred through December 31, 2025, will be recovered in a separate proceeding filed between February 1, 2026, and July 1, 2026.
- Depreciation: The depreciation and amortization period for certain generating plants will be set at 13 years, effective January 1, 2026.
- Tax Credits: Investment Tax Credits (ITCs) and Production Tax Credits (PTCs) will be amortized or deferred according to specific schedules during the extension period.
Material Changes and Regulatory Mechanisms
The settlement introduces several modifications to the 2022 ARP:
- Earnings Sharing: Earnings exceeding the upper ROE limit (11.90%) will be shared: 40% to regulatory assets, 40% refunded to customers, and 20% retained by Georgia Power.
- Earnings Shortfall: There is no automatic recovery for earnings below the lower ROE limit (9.50%). However, Georgia Power may petition for an Interim Cost Recovery (ICR) tariff to adjust rates if projected earnings fall below this threshold.
- Future Rate Case: If the ICR tariff is not implemented or expires, Georgia Power must file a full base rate case by July 1, 2028.
Outlook, Risks, and Contingencies
The terms of the settlement are contingent upon approval by the Georgia PSC, which is scheduled to vote on or before July 1, 2025.
- Contingency: If the settlement is not approved, Georgia Power is required to file its next base rate case by July 1, 2025.
- Forward-Looking Risks: The filing lists numerous risks including regulatory changes, fuel costs, litigation (specifically regarding Plant Vogtle Units 3 and 4), cyber threats, and economic conditions.
- Uncertainty: Management cautions that actual results may differ materially from expectations due to factors outside their control.
Investor Verification Checklist
- Confirm the Georgia PSC's final vote on the Settlement Agreement by July 1, 2025.
- Monitor the filing of the separate storm damage cost recovery proceeding (expected Feb-July 2026).
- Track the impact of the 13-year depreciation period on future earnings starting January 1, 2026.
- Review any updates regarding litigation related to Plant Vogtle Units 3 and 4.
- Verify if an Interim Cost Recovery (ICR) tariff is requested if earnings projections fall below the 9.50% ROE floor.
