Meta is increasing its bet on nuclear generation to power data centers, announcing Friday that it has struck deals with Oklo, Vistra and TerraPower to supply up to 6.6 GW of nuclear power by 2035.
The announcement follows a December request for proposals from Meta, which sought “developers that can help accelerate the availability of new nuclear generators and create sufficient scale to achieve material cost reductions by deploying multiple units.” All the power Meta seeks will be supplied to the PJM region.
In June, Meta reached a 20-year nuclear deal with Constellation to supply its data centers in Illinois.
Meta said Friday that the latest announcement builds on its “ongoing collaboration with electric utility companies and power providers” to meet the electricity demand that the data centers it intends to bring online will create in the next decade without leaving consumers to bear the expenses.
Oklo, an advanced nuclear company formerly chaired by OpenAI CEO Sam Altman, said its deal with Meta advances its “plans to develop a 1.2 GW power campus in Pike County, Ohio, to support Meta’s data centers in the region.”
Those data centers include Meta’s Prometheus AI supercluster in New Albany, Ohio. Prometheus, expected to come online in 2026, will consume at least 1 GW of power and will serve the company’s goal of building a computer superintelligence, Meta CEO Mark Zuckerberg said in a July Threads post.
For the power campus, “pre-construction and site characterization are slated to begin in 2026, with the first phase targeted to come online as early as 2030,” Oklo said in a Friday release. “The plans for the scalable powerhouse facility are expected to expand incrementally to deliver up to the full target of 1.2 GW by 2034.”
Meta said its deal with Vistra involves 20-year agreements to purchase more than 2.1 GW of power from Vistra’s Beaver Valley plant in Pennsylvania and its Perry and David-Besse nuclear plants in Ohio, in addition to uprates at the Ohio plants.
TerraPower, like Oklo, is an advanced nuclear company. Meta said its deal with the company will provide funding to support the development of two of TerraPower’s 345-MW sodium fast reactors. The two Natrium units won’t start supplying power until at least 2032, the release said.
“The agreement also provides Meta with rights for energy from up to six other Natrium units capable of producing 2.1 GW and targeted for delivery by 2035,” Meta said.
