Southern Company Secures Unprecedented $26.5 Billion DOE Loan for Nuclear and Grid Infrastructure
In a historic federal policy and financing development, the U.S. Department of Energy's (DOE) Energy Dominance Financing Program (EDF) closed an unprecedented $26.5 billion loan in February 2026 to support Alabama Power and Georgia Power, two wholly owned subsidiaries of Southern Company (NYSE: SO). Funded under President Trump's Working Families Tax Cut, this represents the largest single loan transaction in the history of the federal energy loan program.
Scope of Generation and Infrastructure Upgrades
The $26.5 billion financing is designed to build, modernize, or upgrade an estimated 16.7 GW of energy generation capacity and transmission infrastructure across Georgia and Alabama. The project statistics and planned allocations include:
- Nuclear Upgrades (6 GW): Following the successful commercial deployment of Vogtle Units 3 and 4—the first new nuclear units constructed in the U.S. in more than 30 years—Southern Company will use a portion of the loan to upgrade Vogtle Units 1 and 2 to expand their generating capacity. The company is also planning future upgrades and license renewals at Plant Hatch and Plant Farley.
- New Gas Generation (5 GW): Capital is being deployed to construct new natural gas generation facilities at Plants Bowen, Wansley, McIntosh, and Yates in Georgia to provide immediate baseload and dispatchable capacity.
- Hydropower Modernization: Modernizing and upgrading existing hydroelectric generation facilities from the Coosa River in Alabama to north Georgia.
- Transmission and Grid Enhancements: Constructing and upgrading over 1,300 miles of transmission lines and grid infrastructure to improve reliability and support growing industrial and data center loads.
Economic and Customer Impacts
The DOE estimates that the massive capital injection will deliver over $7 billion in electricity cost savings to millions of residential, commercial, and industrial customers across Georgia and Alabama, while creating and sustaining thousands of construction and utility jobs.
