Constellation, Google Add 890 MW to PJM Nuclear Fleet as Data Center Demand Strains Grid
3 articles · Updated · CNBC · Oct 6
Summary
$4.3 billion over 20 years will secure 890 megawatts of added nuclear output for Google from Constellation plants on the PJM grid, enough to power more than 600,000 homes.
The capacity will come from uprates at 11 plants in Illinois, Pennsylvania and New Jersey—upgrading turbines, steam generators and control systems—because expanding existing reactors is faster and cheaper than building new supply.
PJM, which serves 13 states and Washington, D.C., needs the power as data-center demand outpaces available generation and new grid connections can take years, driving up electricity costs across the region.
Constellation's stock jumped 15% after the deal, which followed a 190 MW Amazon agreement last week and added momentum to other nuclear-linked names including Vistra, Talen Energy and Centrus.
The agreement fits a broader tech shift toward nuclear for carbon-free, always-on power; Evercore estimates uprates across the existing U.S. fleet could add 4 to 8 gigawatts by the mid-2030s.

Google and Constellation’s $4.3 Billion Nuclear Deal: How Tech Giants Are Powering the AI Era with 890 MW of Clean Energy
Overview
As electricity demand surges due to AI and industrial growth, Google and Constellation Energy have launched a $4.3 billion partnership to rapidly expand clean, reliable nuclear power on the strained PJM grid. By investing in nuclear uprates at existing plants, they will unlock 890 MW of new carbon-free capacity much faster and more affordably than building new reactors. Google anchors the deal, ensuring private funding and protecting local ratepayers from extra costs. Advanced AI from Google Cloud will streamline engineering and regulatory processes, while flexible data center operations help stabilize the grid and support job creation across multiple states.
