What is TerraPower?
TerraPower is a private American nuclear energy technology company headquartered in Bellevue, Washington, focused on developing advanced nuclear power systems to deliver affordable, reliable, and carbon-free energy. Founded in 2006 by Bill Gates and a team of innovators to address climate change, energy security, and global electrification challenges, TerraPower aims to move beyond traditional nuclear technologies by creating next-generation reactors and nuclear science applications, including medical isotopes.
Technology & Products
TerraPower’s flagship offering is the Natrium® advanced nuclear reactor and energy storage system, a sodium-cooled fast reactor integrated with a high-capacity molten salt heat storage system that can provide both continuous baseload power and flexible output to support grids with renewable generation. The company is also developing other advanced reactor concepts, such as Molten Chloride Fast Reactor (MCFR) technology, expanding its portfolio of potential commercial nuclear solutions. TerraPower’s R&D extends to nuclear isotopes for medical and scientific uses.
Market Opportunity
TerraPower operates at the intersection of clean energy transition, energy grid modernization, and nuclear innovation. Its technologies target the growing demand for low-carbon, reliable electricity to support electrification, industrial decarbonization, and energy-intensive applications (e.g., data centers and AI infrastructure). Global and U.S. policy support for advanced nuclear and the need to replace retiring fossil fuel plants create significant market opportunity for advanced reactors like Natrium to compete with traditional generation sources.
Competitive Landscape
TerraPower competes within the advanced nuclear energy sector alongside companies developing small modular reactors (SMRs) and Generation IV technologies. Its Natrium design, backed by public-private partnerships including U.S. Department of Energy cost-sharing and significant private funding, positions it as one of the first advanced reactors moving toward commercial deployment, with construction underway in Wyoming and regulatory milestones achieved. While other developers pursue similar goals, TerraPower’s combination of advanced reactor design, integrated energy storage, high-profile backing, and diversified technology programs differentiates it from many peers.
