Meta announced deals with three nuclear energy companies Vistra, Oklo and TerraPower to fuel its new data centersupercluster Prometheus in New Albany, Ohio.
The company made a 20-year agreement with Vistra to purchase more than 2.1 gigawatts of energy from the Perry (Ohio), Davis-Besse (Ohio) and Beaver Valley (Pennsylvania) power plants.
The deal with Oklo should add 1.2 gigawatts of power in Pike County, Ohio, to support Meta's data centers.
Meta’s investment in TerraPower will provide funding that supports the development of two Natrium plants that can generate up to 690 megawatts of power by 2032.
Shares of Vistra and Oklo skyrocketed higher following the news, climbing 15% and 18%.
Meta CEO Mark Zuckerberg announced Prometheus, a 1-gigawatt AI training cluster spanning across five or more data centers, in July of last year. The company expects Prometheus to come online in 2026 as part of a broader ramp-up in AI infrastructure spending. Last June, Meta also struck a 20-year agreement with Constellation Energy to supply 1 gigawatt of nuclear power for the Clinton Clean Energy Center in Illinois. Meta is planning an even larger 5-gigawatt cluster called Hyperion, which is expected to come online in 2028.
What To Watch For
Artificial intelligence’s surging energy demands are giving nuclear power new momentum as tech giants secure long-term electricity supplies for massive data centers. Amazon, for example, struck a deal with Talen Energy in June 2025 for nearly 2 gigawatts of nuclear power to support its data center in Pennsylvania. Meta, meanwhile, has said its latest agreements could make it “one of the most significant corporate purchasers of nuclear energy in American history,” its chief global affairs officer Joe Kaplan said in an announcement.
