TVA and Type One Energy Accelerate Fusion Commercialization in Tennessee

• TVA and Type One Energy advanced their collaboration in support of a 350-megawatt fusion power plant at TVA’s former Bull Run Fossil Plant near Oak Ridge, Tennessee.
• The agreement continues TVA’s national leadership in advanced nuclear innovation to support the growing energy demands of AI, quantum computing, and advanced manufacturing with reliable, carbon-free power.
• This partnership is another example of how Governor Lee is helping to build a nuclear ecosystem in Tennessee that provides good jobs and opportunities for the people of the Tennessee Valley region

OAK RIDGE, Tenn. (September 19, 2025)– 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.
