OAK RIDGE, Tenn. – The Tennessee Valley Authority (TVA) and Type One Energy announced Friday that TVA has issued a Letter of Intent (LOI) to Type One Energy regarding the utility’s interest in the potential deployment of Type One Energy’s fusion power plant technology at its former Bull Run Fossil site once it is commercially ready.

Infinity Two is a first-generation 350 MWe baseload power plant utilizing Type One Energy’s stellarator fusion technology. The stellarator is currently the only fusion technology to have demonstrated stable, steady-state operation with high efficiency, characteristics which are important for TVA and others in the industry who need to reliably generate on-demand power at competitive prices. Type One Energy is developing Infinity Two using today’s existing materials and fundamental fusion technologies to support near-term deployment of the technology. The LOI also covers potential future use of the prototype facilities as an operator and maintenance training facility for the Infinity Two workforce.

“TVA is a leader in pursuing advanced nuclear technologies we need to power America’s economic prosperity and fuel artificial intelligence, quantum computing and advanced manufacturing,” said Don Moul, TVA President and CEO. “We are strategically partnering with innovative companies like Type One Energy to advance the development of nuclear technologies, and I am excited about the possibility of the first U.S. commercial stellarator fusion power plant being built in the Tennessee Valley. Our region is building a nuclear ecosystem that provides good jobs and opportunities for the people of the Valley.”

TVA is at the forefront of advanced nuclear innovation, and this collaboration reinforces the agency’s commitment to quickly deliver reliable energy to support the nation’s growing power demand.

“We are really honored to be working with TVA on the world’s first private sector fusion power plant project,” said Christofer Mowry, Type One Energy’s CEO. “TVA is a best-in-class energy utility that knows how to build, operate, and maintain complex power generation technologies. This LOI with TVA, and the role it establishes for Type One Energy as the fusion technology provider for their Infinity Two project, is therefore fully aligned with our goal of pursuing the lowest-risk approach to commercializing fusion energy.”

”Tennessee is ready-made to lead America’s energy independence, and today’s announcement further strengthens our position as a leader in safe, clean, and reliable energy,” said Tennessee Governor Bill Lee. “We are proud that the first U.S. commercial stellarator fusion project could be developed in Oak Ridge, creating high-quality jobs and driving continued economic growth and opportunity for Tennesseans.”

Final decisions and definitive agreements regarding the funding and construction of Infinity Two, as well as any agreements to purchase the energy output, are subject to TVA Board approval, regulatory review, and alignment with TVA’s least-cost planning processes and American energy dominance strategy.
