TerraPower and Meta have agreed to develop up to eight Natrium nuclear reactor and energy storage system plants in the United States, a move that could supply Meta with up to 2.8 gigawatts of carbon-free baseload energy. With the Natrium system’s built-in energy storage, total output could be increased to as much as 4 gigawatts.
The agreement supports early development of two initial Natrium units and gives Meta rights to energy from up to six additional units. Each reactor provides 345 MW of baseload power and can ramp up to 500 MW for more than five hours. A dual-unit site could deliver up to 690 MW of firm power and as much as 1 GW of dispatchable electricity.
The companies said delivery of the first units could begin as early as 2032. They also plan to identify a site for the initial dual-reactor project in the coming months.
TerraPower is already building its first commercial-scale Natrium plant in the US, which is expected to be completed in 2030. The company says it has completed its design, established its supply chain and cleared several key regulatory milestones.
The deal brings together TerraPower, a nuclear innovation company, and Meta, the parent company of Facebook, Instagram and WhatsApp. Under the agreement, Meta will provide funding to support deployment of the Natrium plants, marking its largest commitment to advanced nuclear technologies to date.
“With our first Natrium plant under development, we have completed our design, established our supply chain, and cleared key regulatory milestones,” said TerraPower president and chief executive Chris Levesque. He said these steps position the company to deliver multiple units under the agreement.
Meta’s director of global energy, Urvi Parekh, said the deal followed the company’s nuclear request-for-proposals process and reflects its focus on reliable, scalable and clean energy.
The partnership is driven by rising electricity demand, particularly from data centres, and the need for large volumes of firm, carbon-free power in the 2030s. TerraPower says Natrium is the most commercially advanced technology in the emerging reactor sector and the only advanced nuclear design with a completed environmental impact statement and a final safety review supporting a construction permit application currently before the US Nuclear Regulatory Commission.
Both companies say expanding advanced nuclear generation could help meet future energy needs while supporting jobs, innovation and US leadership in energy technology.
