Google and Constellation announced a 20-year power purchase agreement covering 890 megawatts of additional nuclear capacity on the PJM grid. The capacity comes from uprating 11 reactor units Constellation already owns in Illinois, Pennsylvania and New Jersey, with the first uprate due by 2028. The two also signed a separate 15-year supply agreement for a further 2,700 MW from Constellation's existing fleet, and a five-year technology alliance under which Constellation uses Google Cloud and Gemini Enterprise.
The money: Constellation puts more than $4.3 billion into the uprates, backed by a 20-year contracted buyer, and Google secures 3,590 MW in total across the two agreements; the price of the power was not disclosed. For Alphabet this is a long-dated operating cost taken on to run data centres; the release cites demand from digital infrastructure alongside manufacturing and electrification. Suppliers of turbines, steam generators and control systems get the uprate work. The deal adds to the contracts that large cloud companies have signed with nuclear operators to lock in supply.
