Google Will Pay to Uprate Four Georgia Reactors for 96 Megawatts

Georgia Power asked state regulators on Sept. 21 to approve an agreement that would have Google pay for power uprates at four nuclear reactors, adding roughly 96 megawatts to the Georgia grid without a new plant, a new transmission line, or a place in the interconnection queue.

The filings went to the Georgia Public Service Commission under dockets 44280 and 56002 and rest on a new Nuclear Uprate tariff designated NU-1. Google subscribes to the tariff, covers the incremental cost of the uprate work, and receives Zero-Emission Credits representing the carbon-free attributes of the added output. Georgia Power projects the subscription will deliver about $900 million in benefits for customers over the remaining life of the units, and says the structure keeps non-participating ratepayers off the incremental cost. The extended power uprate at Plant Vogtle Units 1 and 2 was already approved in the utility's 2025 integrated resource plan. The matching uprate at Plant Hatch Units 1 and 2 is the new request.

Ninety-six megawatts is small against the plants themselves. Vogtle runs roughly 4.5 gigawatts and Hatch about 1.84 gigawatts. The electrical scope is not a rounding error, though. An extended power uprate is a retrofit, and Georgia Power describes it as targeted modifications and upgrades to key plant equipment such as turbines, pumps, motors, and cooling systems, so the reactors can operate at a higher licensed thermal power level on existing fuel designs and existing plant infrastructure. Pushing more output through a generator that has run since the 1970s and 1980s means work on the output side and on the balance-of-plant loads feeding it.

That work lands almost entirely inside refueling outages. Uprate modifications are scheduled against a fixed window, staffed by contractors who bring in journey-level electricians for a few weeks at a time, and released when the unit comes back online. Motor replacements, feeder and termination work, motor control center and switchgear changes, and instrumentation and control tie-ins are the recurring scope. Outage crews run long scheduled days against a hard restart date, and they are routinely assembled from outside the local market when the local hall cannot fill the call.

Getting on that crew is not the same as getting badged onto a commercial job. Unescorted access inside a nuclear plant's protected area requires background screening, fitness-for-duty testing, and site-specific training before a worker picks up a tool, and that clearance takes time a data center shell never asks for. Electricians who already hold current access at a site are the ones staffing firms call first, and they tend to follow the outage calendar from plant to plant. A Georgia journeyman card gets a worker to the gate. The access process is what gets them through it.

The commission will review the tariff and the Hatch uprate over the coming months. Until it rules, the 96 megawatts and the outage scope behind them stay on paper.
