Google buys a nuclear tariff, and 96 megawatts is the receipt

Google has signed an agreement with Georgia Power to support power uprates at two of the Southern Co. subsidiary's nuclear plants, taking its share of the added output through a subscription program tied to a new nuclear uprate tariff. The uprate is reported to add 96MW of generation capacity to the wider Georgia grid, split across Plant Vogtle, a 4.5-4.8GW station in Burke County near Waynesboro, and Plant Hatch, a 1.84GW site near Baxley. Georgia Power owns both plants, and Southern Nuclear, a sister company under Southern Co., manages their operations.

The mechanism is not yet real: Georgia Power filed with the Georgia Public Service Commission earlier this week, asking regulators to approve the tariff structure and an extended power uprate for Units 1 and 2 at Hatch, and the uprates cannot be completed without the commission's approval. Vogtle is a step ahead, because an EPU for Units 1 and 2 at that plant was approved last year as part of Georgia Power's 2025 Integrated Resource Plan, which means the customer program is being layered onto a capacity plan the commission has already partly blessed.

Ninety-six megawatts is the least consequential number in the deal. Set against Vogtle's 4.5 to 4.8 gigawatts and Hatch's 1.84, the uprate amounts to roughly 1.5% of the two sites' combined capacity, a quantity that will not register against Georgia's load growth, let alone against a hyperscaler's appetite. The megawatts are not what Google is buying.

Google is buying the instrument. Under the agreement it subscribes to the tariff and receives low-carbon credits tied to the carbon-free attributes of the capacity the uprates add, which is to say it is paying for a clean-energy claim attached to incremental output rather than for a new plant. The attraction for Georgia Power is plainer. An uprate is incremental capital against an asset that is already standing. The utility says the extra output comes from modifying equipment already installed — turbines, pumps, motors, cooling systems — so the reactors can operate at higher licensed thermal power levels. Nothing gets sited, nothing gets a fresh interconnection, and the construction program that governs greenfield generation never starts.

The data center delivery bottleneck has moved out of steel and staffing and into supplier slots and raw materials, with equipment queues priced in equity. An uprate sidesteps most of that, because the scarce inputs are replacement parts and outage windows rather than a turbine slot or a transformer on a multi-year lead time. Analysts read the Fervo geothermal tie-up as evidence of baseload scarcity while putting the doubt in the delivery chain. On this structure there is barely a chain to doubt, and the carbon-free attribute arrives without a construction schedule attached.

The open question is cost allocation: Aaron Mitchell, Georgia Power's senior vice president of strategic growth, described the program as a way for customers with clean-energy goals to meet them while preserving grid reliability and producing savings for all customers, and the commission is where that description gets tested. The tariff filing is the document that decides how the uprate's costs land between a subscriber and the rest of the rate base, and the credits are worth only what they are worth if they can be separated from the electrons. Until the commission acts, the agreement has a counterparty and a quantity but, on the record so far, no price.

Google's procurement now runs on two clocks: earlier this month it signed a 22-year power purchase agreement with Fortum at Loviisa in Finland — its first international nuclear agreement, per the coverage — a long-dated contract for output from an operating plant. The Georgia arrangement is the shorter-dated, more copyable version: a tariff priced in a public docket instead of a confidential contract. Compare the PG&E virtual power plant Google is funding, where the price stayed private, or the Lea County option it staked before committing capital. The blank price column has been the defining defect of this cycle's energy deals, and a utility tariff forces the number into the open. The structure is stronger for it.

There is a strategic retreat buried in all this. Over the past year the hyperscalers have moved upstream, and our reporting on Theseus put the anchor tenant on the cap table, double-stacking the lease and the credit on a single demand forecast. Google's Georgia deal does the opposite: it stays a customer, takes no equity, funds no construction, and converts the risk of a large capital project into a subscription payment. Where the asset already exists, that is the better trade, and the fact that Google pursued it at a nuclear site rather than a greenfield one suggests the company has drawn that line for itself.

What comes out of the Georgia docket — the Hatch order and the tariff's terms — deserves reading past the 96MW. If the commission approves the structure, Southern Co. holds a repeatable offer across two plants on its system, and every utility with an uprate candidate in its resource plan has a filing to copy. In this buildout, grid permission, not capital, is the underwriting asset, and a tariff that turns spare thermal headroom into a subscribable product is what that permission looks like once someone finally attaches a price to it.
