Meta signs agreements with Vistra, TerraPower and Oklo for up to 6.6 GW of new and existing nuclear capacity by 2035, notably to power its Prometheus supercluster in Ohio.

### What changes On 9 January 2026, Meta announces agreements with **Vistra, TerraPower and Oklo** for up to **6.6 GW** of new and existing nuclear capacity by 2035. Together with last year's agreement with Constellation Energy, Meta becomes one of the largest corporate buyers of nuclear power in the United States. The agreements follow a request for proposals issued in December 2024. The projects are to power the grids serving Meta's operations, including its Prometheus supercluster in New Albany, Ohio. ### Key facts - Vistra: 20-year power purchase agreements for 2,176 MW from the Perry and Davis-Besse plants (Ohio), plus energy from uprates at those two plants and at Beaver Valley (Pennsylvania), for 2,609 MW in 2034. - TerraPower: funding for development of up to eight Natrium reactors, including two first units totaling 690 MW from 2032 and rights to six more, i.e. 2.1 GW by 2035. - Oklo: support for a 1.2 GW campus in Pike County, Ohio, with electricity prepaid by Meta. - Schedule: purchases begin in late 2026, with full capacity in 2034 for the Vistra part and 2035 overall. - Precedent: an agreement with Constellation Energy signed in 2025 for the Clinton site (Illinois). ### Why it matters Hyperscalers move from electricity contracts to commitments on existing and new reactors, extending plants that were due to close. For cloud customers, AI capacity availability increasingly depends on such long-term supplies. Part of the volume, the advanced reactors of TerraPower and Oklo, is still in development: the 2032 and 2035 dates are goals. ### Takeaway Meta commits up to 6.6 GW of nuclear by 2035, between extending existing plants and advanced reactors.
