Meta Platforms has signed a 20-year power purchase agreement (PPA) with Vistra to buy more than 2,600 megawatts of zero-carbon nuclear energy. Beginning in late 2026, Meta will receive 2,176 MW of baseload power from Vistra’s Perry and Davis-Besse plants in Ohio, plus 433 MW from planned equipment upgrades at those sites and the Beaver Valley plant in Pennsylvania. The deal supports Meta’s rapidly growing artificial-intelligence operations and funds license extensions that could extend each reactor’s life by up to 20 years. Vistra acquired the three facilities in 2023 after they had been slated for retirement and now projects that the upgraded capacity will come online through 2034.

Meta has also entered into a prepaid energy supply agreement with Oklo, a developer of small modular reactors (SMRs), to advance a 1.2-gigawatt nuclear power project in Pike County, Ohio. Under the terms, Meta will fund early procurement of nuclear fuel and site development, helping Oklo begin pre-construction activities this year. Oklo plans to complete site suitability studies and start delivering power to Meta’s AI data centers as early as 2030, a milestone that would make it one of the first SMR facilities in commercial operation in the United States.

In a third agreement, Meta will help finance the development of up to eight molten-salt reactors by Bill Gates–backed TerraPower, securing rights to an initial 690 megawatts from two reactors expected online by 2032 and options on six additional units that could bring total capacity to 3.5 GW by 2035. TerraPower’s design uses superheated sodium to transfer and store energy, enabling up to five hours of dispatchable power. The capital commitment will support engineering, licensing and factory fabrication, with construction beginning in the early 2030s on a site in Wyoming.

These long-term nuclear agreements are projected to supply Meta with reliable, round-the-clock electricity at a predictable price, insulating the company from natural gas price volatility and grid constraints. Collectively, the new contracts will deliver nearly 7.3 GW of nuclear capacity by 2035. Meta estimates that replacing gas-fired generation with nuclear power could reduce its data-center carbon intensity by more than 50%, reinforcing its pledge to achieve net-zero operational emissions. For investors, the deals signal Meta’s commitment to vertically integrate energy supply into its AI expansion strategy, potentially lowering operating costs by hundreds of millions of dollars annually once all projects reach full output.
