TerraPower in Mega Deal with Meta for Eight 345 MW Natrium Advanced Nuclear Plants
TerraPower, a nuclear innovation company, and Meta, which owns and operated multiple social media platforms, announced an agreement to develop up to eight Natrium reactor one and energy storage system plants.
This agreement supports the early development activities for two new Natrium units with rights for energy provided to Meta for up to six additional Natrium units. Each Natrium reactor provides 345 MW of baseload power, with built-in energy storage that can ramp up to 500 MW for over five hours. A dual Natrium reactor site can provide 690 MW of reliable 24/7 365 power, and up to 1 GW of dispatchable electricity. Each site selected by Meta is expect to host twin Natirum reactors for a total of 690 MW at each site.
Under this commercial agreement, Meta will provide funding to support the deployment of the Natrium plants, with delivery of initial units as early as 2032. This is Meta’s largest support of advanced nuclear technologies to date and is the firm’s first direct investment in a new nuclear build. It is expected that many of the data center sites selected to be powered by the TerraPower reactors will by hyperscalers supporting Meta’s customers using the platform’s artificial intelligence products and capabilities.
At a hypothetical cost of $6,000/kW, each Natrium reactor will cost about $2.1 billion and eight of them would require about $17 billion. The size of the deal supports significant economies of scale for TerraPower’s supply chains as well as for the manufacturing of the reactors.
Power Will Support Meta Data Centers
Each reactor site will provide power for Meta’s data centers. Meta owns and operates several prominent social media platforms and communication services, including Facebook, Instagram, WhatsApp, Messenger and Threads. According to official Meta statistics, the combined user community world-wide is 3.9 billion users a month.
The companies will target identification of a specific site for the initial dual reactor unit later this year. The press materials did not indicate whether all sites would be limited to the U.S. Also, it was not indicated whether Meta would connect these sites to local/regional grids or select some or all of them as private wire installations for its data centers which would by pass the current multi-year backlog of FERC approvals of new grid connections.
The eight 345 MW advanced sodium cooled reactors would provide Meta with up to 2.8 GW of carbon-free, baseload energy. Each reactor comes with the Natrium technology’s innovative built-in energy storage system providing the capacity to boost total output to 4 GW of power.
Chris Levesque, TerraPower president and CEO said, "With our first Natrium plant under development, we have completed our design, established our supply chain, and cleared key regulatory milestones. These successes mean our TerraPower team is well-positioned to deliver on this historic multi-unit delivery agreement."
Urvi Parekh, director of global energy, Meta, said, "This agreement with TerraPower, the result of Meta’s nuclear RFP process, which identified leading developers of nuclear energy to help us advance our energy goals, marks a significant step forward in advancing next-generation nuclear technology. Supporting new nuclear energy generation spurs job growth, drives innovation in our local communities, and reinforces America’s leadership in energy technology."
TerraPower began construction on the first commercial-scale, advanced nuclear project in the United States, which is expected to be complete in 2030. The Natrium plant is the only commercial advanced nuclear technology with a complete environmental impact statement and final safety review as part of a...
