Meta has signed nuclear agreements with Vistra, TerraPower and Oklo that could unlock up to 6.6 gigawatts of capacity by 2035, tying the procurement to the company’s Prometheus AI “supercluster” in New Albany, Ohio, in the PJM grid region.
The deals combine 20-year power purchases from existing reactors with development funding for new advanced reactor projects, which Meta said are meant to add “clean, reliable” generation to the grid.
Near-term supply: Vistra
The near-term supply comes from Vistra. Vistra said the companies signed 20-year power purchase agreements starting in late 2026 for 2,176 megawatts from the Perry and Davis-Besse plants in Ohio and the Beaver Valley plant in Pennsylvania.
According to the announcement, agreements support 433 MW of uprates across those facilities, with the incremental capacity phased in through 2034.
Meta positioned the timing around a tightening U.S. power market for large-load campuses. PJM has said its 2025 long-term load forecast projects 32 GW of peak load growth from 2024 to 2030, with “all but 2 GW” attributed to data centers, and it has launched a process aimed at balancing reliability with that onrush.
Meta’s AI spending plans are also expanding: in its Q3 2025 results, the company said it expects 2025 capital expenditures of $70 billion to $72 billion and warned 2026 spending will grow as it builds AI infrastructure.
Advanced reactors: TerraPower and Oklo
The longer-dated portion of Meta’s portfolio pushes into first-of-a-kind deployments. TerraPower said Meta will fund early development for two Natrium units capable of supplying up to 690 MW of firm power, with delivery targeted as early as 2032, and it includes rights to energy from up to six additional Natrium units targeted by 2035.
Oklo said its agreement provides a mechanism for Meta to prepay for power and fund development work supporting a 1.2-GW advanced nuclear campus in Pike County, Ohio, with pre-construction and site characterization slated for 2026 and a first phase targeted as early as 2030.
For enterprises building or buying large-scale AI capacity, the deals suggest that power procurement is now a first-order constraint, not a late-stage utility task.
Deloitte has argued that data center electricity demand could rise sharply by the mid-2030s, and it points to nuclear as a source of always-on generation that can help meet 24/7 load needs as grid congestion grows. PJM, for its part, has warned that the scale and speed of large-load additions is creating resource adequacy concerns and pricing pressure in its footprint.
Meta’s approach illustrates a pattern in which hyperscalers are mixing “keep existing reactors online longer” with bets on advanced nuclear timelines.
Meta separately signed a 20-year PPA with Constellation in June 2025 for the 1,121-MW Clinton Clean Energy Center in Illinois. Peers are pursuing similar structures: Google and Kairos Power said their agreement creates a path to deploy 500 MW of advanced nuclear by 2035, and Amazon and X-energy said they are collaborating on a goal of more than 5 GW of projects by 2039.
Risks and watchpoints
A key watchpoint is execution risk on the advanced reactor side, where licensing and schedules may matter more than headline gigawatts. Oklo’s prior Aurora project illustrates the regulatory bar: the U.S. Nuclear Regulatory Commission denied Oklo’s combined license application in 2022 for failing to provide enough information, and the Federal Register notice states the denial was “for failure to provide information.”
Near term, Vistra’s deliveries begin in late 2026 and uprates run through 2034, while TerraPower and Oklo will need to move from development funding and site work to licensing and construction milestones over the coming decade, against the backdrop of PJM’s tightening load outlook.
