Meta has entered long-term nuclear power agreements in the United States, securing electricity for its next-generation AI data centre expansion.
The technology giant signed 20-year deals with Vistra to source energy from three nuclear plants in Ohio and Pennsylvania, while also committing to new reactor projects with Oklo and TerraPower. Following the announcements, Vistra shares rose roughly 8%, and Oklo stock jumped nearly 20% in early trading.
The agreements are aimed at powering Meta’s Prometheus AI supercluster in New Albany, Ohio, a facility that will demand electricity on a gigawatt scale. Under the Vistra contracts, Meta will source power from Ohio’s Perry and Davis-Besse plants and Pennsylvania’s Beaver Valley facility, with the Ohio reactors alone producing 2.176 gigawatts. The arrangement will also fund plant upgrades and extend operational lifespans, with some reactors licensed through 2036 and Beaver Valley running until 2047.
Meta said its combined nuclear agreements, including a 2025 deal with Constellation Energy for an Illinois reactor, will secure up to 6.6 gigawatts of nuclear energy by 2035—equivalent to the output of six large-scale reactors. Joel Kaplan, Meta’s chief global affairs officer, described the move as making the company “one of the largest corporate purchasers of nuclear energy in American history.”
Beyond existing plants, Meta is supporting next-generation reactors. It is partnering with TerraPower to develop two advanced reactors expected to generate up to 690 megawatts by 2032, with rights to additional units totaling six reactors by 2035. TerraPower, founded by Bill Gates, positions these small modular reactors (SMRs) as faster, factory-built alternatives to traditional nuclear plants.
Meta is also collaborating with Oklo on 1.2 gigawatts of nuclear power in Ohio, with initial output projected for 2030. SMRs are central to both projects, allowing for quicker, scalable deployment, though critics question their cost efficiency compared to conventional reactors.
The deals come as U.S. electricity demand grows, driven largely by the expanding data centre sector. Government projections show total power consumption climbing from 4,097 billion kilowatt-hours in 2024 to 4,283 billion by 2026, with commercial electricity use, including data centres, expected to increase 3% in 2025 and 5% in 2026, the fastest growth in two decades. BloombergNEF estimates demand from data centres could reach 106 gigawatts by 2035.
For Meta, nuclear energy provides reliable, long-term power that complements wind and solar. The agreements not only hedge against rising electricity costs but also reflect a shift in how major tech companies approach energy, moving from short-term contracts to infrastructure-scale commitments.
