Meta Platforms has agreed to purchase over 2,600 megawatts of carbon-free nuclear power from Vistra under 20-year contracts designed to support its rapidly expanding artificial intelligence data centers. The deal covers 2,176 MW of existing generation at Vistra’s Perry and Davis-Besse plants in Ohio, plus 433 MW of incremental capacity from planned upgrades at those facilities and at the Beaver Valley plant in Pennsylvania. Power deliveries will begin in late 2026 and continue through 2046, with Vistra pursuing license extensions for all three reactors to extend their operational lives by up to 20 years beyond their original retirement dates.

Meta will prepay Oklo for future energy deliveries from a planned 1.2-gigawatt small modular reactor (SMR) complex in Pike County, Ohio, accelerating development and securing rights to the entire output. The prepayment covers early procurement of nuclear fuel and site studies, enabling Oklo to advance Phase 1 construction with an expected online date by 2030. This commitment marks one of the largest corporate backing arrangements for an SMR startup, underlining Meta’s strategy to lock in stable, low-carbon baseload power.

Meta has signed long-term agreements with TerraPower to offtake power from two first-of-a-kind sodium-cooled reactors, each rated at 345 MW, plus an integrated thermal storage system capable of delivering an additional 100–500 MW for up to five hours. The initial two reactors are slated to come online by 2032, providing 690 MW of continuous power, with options to purchase output from six more units—potentially totaling 2.8 GW of reactor capacity and 1.2 GW of storage by 2035. This arrangement positions Meta to become the largest hyperscaler customer of advanced nuclear technology.
