Meta has announced agreements with three nuclear power providers as part of its efforts to secure the energy resources for its AI ambitions.

The arrangements with Vistra, TerraPower and Oklo, which are all working on advanced nuclear power technologies, are for Meta’s Prometheus supercluster computing system that is being built at a data centre in New Albany, Ohio. No financial terms were disclosed.

Meta chief executive officer Mark Zuckerberg announced Prometheus in July, describing the system as one of the keys to the development of the company’s advanced artificial intelligence efforts. Meta has said it expects Prometheus to come online sometime in 2026.

In working with the three companies on energy production, Meta said the projects should add 6.6 GW of power by 2035, equivalent to the capacity of about six large-scale nuclear power reactors.
