Meta on Friday said it has reached agreements with three nuclear energy providers, including one backed by OpenAI CEO Sam Altman, as it moves to secure power for its expanding artificial intelligence operations.

The deals involve Vistra, TerraPower and Oklo, all developers of nuclear power technologies, and will support Meta’s Prometheus supercluster computing system under construction at a data centre in New Albany, Ohio.

Financial details were not disclosed.

Meta CEO Mark Zuckerberg announced Prometheus in July, describing the system as a critical pillar of the company’s push into advanced artificial intelligence. Meta has said it expects the supercluster to become operational in 2026.

Meta added that its partnerships with the three energy firms are expected to deliver about 6.6 gigawatts of power by 2035—more than the total electricity demand of the U.S. state of New Hampshire.

“State-of-the-art data centers and AI infrastructure are essential to securing America’s position as a global leader in AI,” Meta policy chief Joel Kaplan said in a statement.

Meta said it will help finance Vistra’s nuclear power plants in Ohio and Pennsylvania, enabling the facilities to extend their operating lifespans and boost electricity output.

The nuclear projects being developed by the other two companies are still in the early stages.

The company added that the agreements are expected to generate thousands of construction jobs and hundreds of permanent operational roles.

The agreements underscore Meta’s latest push to secure reliable energy supplies for its AI infrastructure as the company advances toward Zuckerberg’s vision of “superintelligence”—AI systems capable of far surpassing human performance across a wide range of tasks.

Meta’s megacap rivals are also turning to nuclear power to support their AI ambitions.

In March, Meta, Amazon and Google signed a pledge backing a tripling of global nuclear energy production by 2050.
