Google Signs 20-Year Nuclear Power Purchase Agreement with Constellation… Expands New Nuclear Capacity by 890 MW

Google has signed a long-term power purchase agreement with Constellation Energy, one of the largest nuclear power plant operators in the U.S., to increase the output of existing reactors and add 890 MW of new nuclear generation capacity to the PJM power grid. The key to this initiative is the “uprate” method—improving existing reactors and facilities to increase efficiency and output—rather than building new nuclear power plants from scratch. This agreement demonstrates how the power demand from AI data centers is changing even the way investments in the power grid are made, As an example of this,
