TerraPower plans to announce its first data center power project this year, with construction expected to begin in 2027. The Bill Gates-founded startup has not identified the customer, although Meta agreed in January to buy eight of its Natrium power plants. The project would be TerraPower's second power plant, after its first Natrium plant began construction in Wyoming. Its 345-megawatt molten salt-cooled reactor is designed to keep operating at full output while storing excess heat in molten sodium, allowing the plant to respond to rapid changes in data center demand without frequently ramping the reactor itself. Nuclear power's 92.5% U.S. capacity factor makes it suited to continuous AI electricity demand, while the integrated storage system could help manage volatile loads and complement grids with substantial wind and solar generation.
