Google signs Constellation deal for 890 megawatts of added nuclear capacity

Google has signed a power purchase agreement with Constellation Energy that will add 890 megawatts of nuclear capacity to the PJM grid through upgrades at existing plants, the company said in an Oct. 6 announcement.

The deal finances physical and digital upgrades at six operating nuclear plants in Illinois, Pennsylvania and New Jersey, covering 11 reactors. The added capacity is due online before the end of 2032, according to Google's post.

Google said the work will sustain roughly 4,400 existing jobs and support about 7,200 construction jobs. The post did not disclose financial terms.

Bigger nuclear tally

With this agreement, Google said it has enabled more than 1.5 gigawatts of new U.S. nuclear capacity from uprates, which raise the output of existing reactors, and from restarts of dormant plants.

The Energy Department has set a goal of 5 gigawatts of nuclear expansion through uprates and restarts by 2030. Google said its agreements are expected to enable nearly 25% of that goal by the end of the decade.

Cloud tie-in

As part of the expanded collaboration, Constellation is deploying Google Cloud's Gemini Enterprise across its core operations to speed uprate planning and construction, Google said.

Google said it is serving as anchor customer for the projects and that other grid customers will bear none of the associated costs.
