Meta-TerraPower Natrium Power Agreement

TerraPower and Meta announced an agreement to develop up to eight Natrium reactor and energy storage system plants in the United States. TerraPower says the initial agreement supports early development activities for two new Natrium units, with rights for energy provided to Meta from up to six additional units. Each Natrium reactor provides 345 MW of baseload power, and TerraPower says a dual Natrium unit can provide 690 MW of firm power and up to 1 GW of dispatchable electricity.

Meta's official announcement says the TerraPower agreement supports two new Natrium units capable of generating up to 690 MW of firm power with delivery as early as 2032, plus rights for energy from up to six other Natrium units capable of producing 2.1 GW targeted by 2035. TerraPower separately says its first Natrium reactor is under construction near Kemmerer, Wyoming, but the Meta/TerraPower agreement says the companies will identify a specific site for the initial dual-reactor unit in the coming months. ADCI retains 690 MW as official program power capacity and removes the legacy Kemmerer AI-campus framing and point precision.
