Google and Constellation Energy said they have entered into a long-term agreement tied to adding 890 megawatts of new nuclear capacity to the PJM Interconnection grid. A separate report carried by Yahoo Finance said the agreement would add that capacity through upgrades at 11 nuclear plants in 3 states.
In its own announcement, Google said the Constellation agreement brings the total new nuclear capacity it has enabled for the U.S. energy system from uprates and restarts to more than 1.5 gigawatts. That is Google's description of the project and its broader nuclear push.
Bloomberg separately reported that Alphabet agreed to a 20-year deal to buy nuclear power from Constellation Energy. Based on the supplied evidence, that 20-year term comes from Bloomberg's reporting, while the companies' own public language centers on a long-term agreement and the added capacity.
The investment is also expected to reach Illinois plants. The Chicago Tribune, citing the company, reported that about half of Constellation's investment, or $2 billion, will be spent at the Byron, Braidwood, LaSalle and Quad Cities plants in Illinois.
Barron's placed the agreement in a broader market trend, writing that Alphabet and others are scrambling for enough power for their AI data centers. In this article, that functions as context about how some outlets are framing big tech's interest in nuclear power, not as independent proof of the specific purpose of this agreement.
For now, the clearest supported development is that Google and Constellation announced a long-term nuclear agreement tied to 890 MW of additional capacity on the PJM grid, while outside reporting adds details including the reported 20-year term and the Illinois investment footprint.
