Meta has signed three major nuclear energy agreements to fuel its new AI data center supercluster, Prometheus, in New Albany, Ohio. The deals are with Vistra, Oklo, and TerraPower, reflecting Big Tech’s growing reliance on nuclear power to meet rising AI energy demands.
The 20-year agreement with Vistra will supply more than 2.1 gigawatts of energy from the Perry and Davis-Besse plants in Ohio, and the Beaver Valley plant in Pennsylvania.
The Oklo deal adds 1.2 gigawatts of power from a plant in Pike County, Ohio, dedicated to supporting Meta’s data centers.
Meta’s investment in TerraPower will fund the development of two Natrium reactors, which are projected to generate up to 690 megawatts by 2032. Following the announcement, shares of Vistra and Oklo surged 15% and 18%, respectively.
Meta CEO Mark Zuckerberg unveiled Prometheus in July 2025 as a 1-gigawatt AI training cluster spanning five or more data centers, expected to be operational in 2026. The company is also planning a 5-gigawatt Hyperion cluster by 2028.
These moves come amid the broader trend of AI infrastructure driving corporate demand for long-term nuclear power contracts. Last year, Meta signed a 20-year deal with Constellation Energy to supply 1 gigawatt for its Clinton Clean Energy Center in Illinois. Amazon similarly secured nearly 2 gigawatts of nuclear energy from Talen Energy in 2025.
Meta’s chief global affairs officer, Joe Kaplan, said the company could become “one of the most significant corporate purchasers of nuclear energy in American history,” highlighting the scale of Big Tech’s energy ambitions.
