Google signs 20-year deal to expand nuclear power at US plants

Google has signed a 20-year power purchase agreement with Constellation Energy to support 890 megawatts of additional nuclear generating capacity at six existing US sites. The agreement will increase the plants’ output; it does not fund the construction of new nuclear facilities.

The added capacity will supply the PJM Interconnection, a grid network spanning 13 states and an estimated 67 million US residents. Google’s expanding AI data centers are driving increased energy demand, according to TechRadar.

Google’s Global Head of Data Center Energy, Amanda Peterson Corio, said the company has now enabled more than 1.5 gigawatts of new nuclear capacity for the US energy system. TechRadar estimates that this could be around 2.5 to 3 times Google’s earlier total of about 610 megawatts.

Google expects the first uprated plant to go live in 2028, with the full 890 megawatts delivered by the end of 2032. Constellation said it expects to invest more than $4.3 billion in the program. Google did not disclose its financial contribution. Corio highlighted potential job impacts, particularly temporary construction roles.

Constellation CEO Joe Dominguez said preserving and expanding existing nuclear generation, alongside developing new clean generation, is critical to meeting rising energy needs. The agreement’s capacity is not exclusively for Google’s data centers, but TechRadar reports it will support their expansion and add supply to the grid.
