These AI projects include Prometheus, the first of several supercluster computing systems, which is expected to come online in New Albany, Ohio, sometime this year. Meta is funding the construction of new nuclear reactors as part of the agreements, the first of which may come online “as early as 2030.” These announcements are part of Meta’s ongoing goal to support its future AI operations with nuclear energy, having previously signed a deal with Constellation to revive an aging nuclear power plant last year.

Financial information for the agreements hasn’t been released, but Meta says that it will “pay the full costs for energy used by our data centers so consumers don’t bear these expenses.”

“Our agreements with Vistra, TerraPower, Oklo, and Constellation make Meta one of the most significant corporate purchasers of nuclear energy in American history,” Meta’s chief global affairs officer, Joel Kaplan, said in the announcement. “State-of-the-art data centers and AI infrastructure are essential to securing America’s position as a global leader in AI.”
