Constellation, Vistra uprate deals signal fastest path to new nuclear megawatts
Constellation Energy, Google, and the U.S. DOE announced a 20-year power purchase agreement for 890 MW of nuclear uprates at 11 reactors, with Constellation investing $4.3B. The DOE also committed up to $4.2B for Vistra's nuclear upgrades, adding 433 MW of capacity. Both deals aim to boost existing nuclear capacity to meet rising electricity demand, particularly in the PJM Interconnection.
