Meta has announced three new power agreements to secure nuclear energy for its data centers, marking a significant step in its strategy to meet the growing electricity demands of its AI infrastructure. The deals include partnerships with two nuclear startups—Oklo and TerraPower—and a larger, established energy provider, Vistra. The 20-year agreement with Vistra will provide Meta with 2.1 gigawatts of power from two existing nuclear plants in Ohio—Perry and Davis-Besse. Vistra will also expand capacity at these sites and at its Beaver Valley plant in Pennsylvania, adding 433 megawatts of new output. These upgrades are expected to come online in the early 2030s and will offer the most immediate and cost-effective power solution, as electricity from operating nuclear reactors remains among the cheapest on the grid. Meta is also securing 1.2 gigawatts from Oklo, a small modular reactor (SMR) startup that went public in 2023. Oklo plans to build multiple Aurora Powerhouse reactors in Pike County, Ohio, each producing 75 megawatts. The first units could begin delivering power as early as 2030. However, Oklo still faces regulatory hurdles, as its reactor design awaits final approval from the Nuclear Regulatory Commission. The company has already signed a major deal with data center operator Switch, but this new agreement with Meta could help validate its long-term business model. TerraPower, co-founded by Bill Gates, is another SMR innovator with a more advanced development path. The company’s reactor design uses molten sodium to transfer heat and includes a thermal storage system that can provide 100 to 500 megawatts of power for over five hours when demand is low. The first two reactors for Meta will deliver 690 megawatts, with the option to purchase up to six more, bringing total capacity to 2.8 gigawatts and 1.2 gigawatts of storage. Power delivery is expected to begin as early as 2032. TerraPower is already working with GE Hitachi to build its first plant in Wyoming, and it has made faster progress through the NRC approval process than many of its peers. All three deals stem from a request for proposals Meta issued in December 2024, seeking 1 to 4 gigawatts of new generating capacity by the early 2030s. The power will largely flow through the PJM interconnection, a major grid serving 13 Mid-Atlantic and Midwestern states that is now under significant strain due to the rapid growth of data centers. While financial details of the deals were not disclosed, the Vistra contract is expected to be the most economical. SMR costs remain uncertain, but both Oklo and TerraPower have set ambitious targets—$80 to $130 per megawatt-hour for Oklo and $50 to $60 for TerraPower in later plants. The first units are likely to be more expensive, but the long-term goal is to scale production and reduce costs through mass manufacturing. The deals highlight a growing trend: tech companies are turning to nuclear power for reliable, carbon-free baseload energy to support AI workloads. With existing reactors limited in number and capacity, startups like Oklo and TerraPower are emerging as key players in the race to deliver scalable, clean energy solutions.
