TerraPower begins U.K. regulatory approval process
Seattle-based TerraPower signaled its interest this week in building its Natrium small modular reactor in the United Kingdom, the company announced.
TerraPower sent a letter to the U.K.’s Department for Energy Security and Net Zero, formally establishing its intention to enter the U.K. generic design assessment (GDA) process. This is TerraPower’s first step in deployment of its Natrium technology—a 345-MW sodium fast reactor coupled with a molten salt energy storage unit—on the international stage.
2024 ANS Annual Conference
Peter Freed has spent over 20 years working at the intersection of clean energy and climate. He is currently an advisor to companies and investors looking to maximize business and climate outcomes across the energy sector. His expertise includes enabling load growth; data center development; deployment of advanced energy technologies; utility, regulatory, and policy engagement; and commercial negotiation and contracting — all with a focus on accelerating the trajectory to the clean, reliable grid of the future.
Peter was most recently the Director of Energy Strategy at Meta where his team worked to advance grid decarbonization and reliability by creating solutions that overcome systemwide obstacles while also meeting Meta’s energy and net zero goals. Peter is also a founding board member of the Clean Energy Buyers Alliance. He holds a BS in Earth Systems from Stanford University.
