Google secures nuclear power for its data centers for 20 years

Google and Constellation Energy have signed a 20-year nuclear power agreement to increase electricity production from 11 existing reactors in Illinois, Pennsylvania and New Jersey.

The deal covers 890 megawatts of capacity and more than $4.3 billion in investment to upgrade the plants, according to The Wall Street Journal. The improvements are expected to add capacity to the grid roughly equivalent to building a new large-scale reactor.

Constellation expects to deliver the first project in 2028, with the remaining upgrades scheduled to continue through 2032 or 2033. The companies also agreed to an additional 2,700 megawatts of nuclear power under a separate 15-year arrangement.

The agreement comes as major technology companies seek additional electricity to power the rapid expansion of data centers and increasingly turn to nuclear energy. Google is also working on nuclear projects in Georgia and Iowa, while Microsoft, Amazon and Meta have reached similar agreements to support or expand nuclear generation.
