Business Context and Reporting Period
This Form 8-K is a combined current report filed by The Southern Company and Georgia Power Company on December 19, 2025. The filing addresses a regulatory settlement approved by the Georgia Public Service Commission (PSC) regarding Georgia Power's resource certification and future rate case commitments.
Key Financial Metrics and Capital Investment
- Approved Resources: The PSC certified all 9,885 megawatts of requested resources in the All-Source Certification Proceeding.
- Capital Investment: Company-owned projects involve approximately $16.3 billion in projected capital investment (excluding allowance for funds used during construction).
- Investment Timeline: Approximately $14 billion of the capital investment is expected to be incurred between 2026 and 2029.
- Customer Benefit Commitment: Georgia Power agreed to file its next base rate case to ensure incremental revenue from large load customers provides a downward pressure of at least $556 million per year on a levelized basis for 2029, 2030, and 2031.
- Residential Impact: The commitment equates to approximately $8.50 per month ($102 per year) in benefits for a typical residential customer using 1,000 kilowatt-hours per month.
Material Changes and Regulatory Actions
The primary material event is the approval of the Settlement Agreement resolving the All-Source Certification Proceeding. This approval certifies the requested capacity resources at their individual project costs. A material condition of this approval is the requirement for construction monitoring by the Georgia PSC and the specific agreement regarding future rate case filings to ensure customer benefits.
