Google deal with Constellation to add 890 MW of nuclear capacity by 2032
Google says it will be the anchor customer for upgrades to 11 Constellation reactors at six plants, lifting the nuclear capacity it has enabled to over 1.5 GW.
AI illustrationGoogle said on 6 October 2026 that it has signed a power purchase agreement with Constellation Energy that is intended to bring 890 megawatts of additional nuclear capacity to the PJM grid. Google said the projects will add that capacity before the end of 2032.
The deal finances physical and digital upgrades at six operating nuclear plants in Illinois, Pennsylvania and New Jersey. According to Google, it acts as the anchor customer for the work, giving Constellation the long-term revenue certainty it needs to invest in upgrades for 11 of its reactors. Google said other grid customers will bear none of the associated costs.
Such upgrades, known as uprates, raise the output of an existing reactor by modernising equipment such as turbines, steam generators and digital control systems. Google said the 890 MW is roughly the equivalent of adding an entirely new large reactor, and that the work is happening years quicker than building one from scratch.
The company said the financing, driven by growth in its data centres, will sustain roughly 4,400 existing jobs and support approximately 7,200 new construction jobs. The PJM grid spans 13 states across the Mid-Atlantic and Midwestern U.S. and serves 67 million Americans, according to Google.
As part of the expanded collaboration, Google said, Constellation is deploying Google Cloud's Gemini Enterprise agentic workflows across its core operations to speed up uprate planning, streamline construction and optimise plant output.
With this agreement, Google said it has now enabled over 1.5 GW of new nuclear capacity for the U.S. energy system through uprates of existing reactors and restarts of dormant facilities. The United States Department of Energy has set a goal of enabling 5 GW of domestic nuclear expansion by 2030 through uprates and restarts. Google said its agreements on existing nuclear infrastructure are expected to enable nearly 25% of that goal by the end of the decade.
The company also pointed to other nuclear projects. In Georgia, it signed an agreement with Georgia Power to support uprates across four reactor units, which it said is expected to enable approximately $900 million in ratepayer benefits. In Iowa, it is working with NextEra Energy to restart the Duane Arnold Energy Center, bringing over 600 MW of nuclear power online. In Tennessee, it is partnering with Kairos Power and the Tennessee Valley Authority to deploy advanced nuclear reactors and reinvest in Oak Ridge.
