Georgia Power and Google agreed to fund nuclear uprates at Plants Vogtle and Hatch that add about 96 MW of capacity, with Google subscribing to a new NU-1 tariff and receiving the associated Zero-Emission Credits. Georgia Power projects roughly $900 million in customer benefits over the life of the units, and the deal now awaits Georgia Public Service Commission approval.
Georgia Power will squeeze 96 megawatts of additional output from two existing nuclear plants using money from Google, a contract that converts hyperscaler power demand into ratepayer savings rather than a new reactor order book.
The agreement, filed Monday with the Georgia Public Service Commission under Docket 44280 and Docket 56002, covers uprates on Georgia Power's owned share of units at Plant Vogtle near Waynesboro and Plant Hatch near Baxley. Google subscribes to a new Nuclear Uprate tariff, designated NU-1, and receives the Zero-Emission Credits tied to the incremental generation. Georgia Power puts the projected customer benefit at roughly $900 million over the life of the units.
"Many of our large customers have specific clean energy goals, and we continue to work with the Georgia PSC to create programs that not only help them meet their goals, but align with our Customer Protection Pledge," Aaron Mitchell, senior vice president of strategic growth at Georgia Power, said.
The mechanics matter more than the headline capacity. An extended power uprate, or EPU, raises a reactor's licensed thermal power level through targeted changes to turbines, pumps, motors and cooling systems, letting the unit produce more steam and more electricity without new fuel design or new plant footprint. The Georgia PSC already approved an EPU for Vogtle Units 1 and 2 in the 2025 Integrated Resource Plan. Monday's filing adds a request to approve a fresh EPU for Hatch Units 1 and 2.
For scale, 96 MW is roughly 0.6% of the 1,100 MW nameplate capacity of each Vogtle AP1000 unit, and it arrives at a fraction of the cost and timeline of new-build generation. Georgia Power's four nuclear units — two at Vogtle, two at Hatch — anchor a fleet that supplied more than 25% of the state's electricity last year, according to the company.
The NU-1 design is the part other utilities are likely to copy. Google's subscription covers the incremental cost of the uprate work, and the tariff is structured so that non-participating customers are shielded from those costs — the same architecture Georgia Power has used for years on its renewable energy programs, where large buyers underwrite new capacity in exchange for the environmental attributes.
That structure answers the sharpest political objection to data-center growth: that hyperscaler load raises bills for everyone else. Georgia Power's framing is explicit — large-load growth should benefit all electric customers, not just the buyer signing the contract.
"Google data centers are long-term investments in the communities we call home," Lucia Tian, director of advanced energy technologies at Google, said. "This collaboration with Georgia Power ensures that digital infrastructure growth goes hand-in-hand with positive local impact."
The deal also gives Google something it cannot buy on the open market at scale: firm, carbon-free, round-the-clock power with a documented emissions attribute. Solar and wind contracts deliver intermittency; nuclear uprates deliver baseload. For a company running AI training clusters that draw power continuously, the distinction is the entire point.
The template is portable. Every U.S. nuclear operator with un-uprated capacity now has a worked example of how to monetize it without a rate case fight — sell the increment to a creditworthy corporate buyer, pass the savings to the general rate base, and let the regulator bless the structure. Constellation Energy, Vistra and Duke Energy all operate fleets where similar uprates have been studied or pursued, and all face the same question of who pays for the incremental capital.
The constraint is physical, not financial. Uprates are bounded by licensing limits and equipment tolerances, so the aggregate megawatts available across the U.S. fleet are measured in single-digit gigawatts, not the tens of gigawatts that AI data-center forecasts imply. That ceiling is precisely why hyperscalers have also signed long-term contracts tied to new-build and restart projects elsewhere.
Southern Company shares closed at $85.46, down 0.07%, on a day when Alphabet rose 1.55% to $354.97, according to MarketScreener data. The muted utility reaction reflects the deal's size: $900 million of lifetime customer benefit spread across a 2.8-million-customer base is real but not transformative to earnings, and the capacity is contingent on PSC approval.
The next checkpoint is the Georgia PSC's review of the NU-1 tariff and the Hatch EPU request. Approval would make Georgia the first state with a standing nuclear uprate tariff on its books — and give every other utility commission in the country a filing to point at.
