Constellation Energy (CEG) Is Up 10.1% After Google Backs 20-Year Nuclear Power Expansion

In early October 2026, Google and Constellation Energy announced a long-term clean energy collaboration that will add 890 megawatts of new nuclear capacity to the PJM grid under a 20-year power purchase agreement, alongside a 15-year, 2,700 megawatt supply deal and more than US$4.30 billion of nuclear fleet investments supported by Google Cloud's AI technology. Coming on the heels of a separate 20-year agreement with Amazon backing over US$3.00 billion of upgrades and a 190 megawatt uprate at Maryland's Calvert Cliffs plant, these contracts show how hyperscale customers are directly underwriting incremental nuclear capacity, life extensions and digital optimization across Constellation's fleet.
