Google and Constellation Sign Nuclear Power Agreement

Google and Constellation Energy have announced a 20-year power purchase agreement covering 890 megawatts of planned nuclear capacity increases at 11 operating units in Illinois, Pennsylvania and New Jersey. The upgrades are expected to begin delivering additional capacity by 2028, though the companies have not identified the first unit or provided a schedule for the remaining work. Constellation said it plans to invest more than $4.3 billion in the upgrades. That figure represents the company’s planned investment, not a disclosed payment by Google. The companies said the work would increase output at existing reactors rather than build new nuclear plants. The agreement is part of a broader set of arrangements. Google and Constellation also signed a separate 15-year supply agreement covering 2,700 megawatts from Constellation’s existing generation fleet. The start date for that agreement was not disclosed. The companies have not published power prices or the total amount Google will pay under either power agreement. A separate five-year technology agreement covers Google Cloud and Gemini Enterprise services for Constellation.
