The state of Tennessee Monday issued a fusion-specific byproduct material license forType One Energy to build a commercial fusion plant at the Bull Run site in Clinton, Tenn.
This marks the first-ever fusion license to be issued by a state, the Tennessee Department of Environment and Conservation said in a press release. This decision also comes months after Tennessee established a state-level nuclear fusion regulatory framework in June.
Tennessee Gov. Bill Lee (R), Type One Energy and Tennessee Valley Authority (TVA) officials announced the issuance at the annual meeting of the Organization of Agreement States held in Nashville. Type One Energy and TVA filed a byproduct material license application with the state in January.
Type One Energy and TVA plan to break ground this year for the first phase of Project Infinity. The facility will be at Bull Run, the site of a shuttered TVA coal-fired power plant. The fusion company hopes the plant will be online by 2034. The company said its commercial site will be used as a fusion development campus used in collaboration with the Department of Energy’s Oak Ridge National Laboratory, TVA and University of Tennessee.
Type One Energy’s Project Infinity will have its Infinity One prototype, a workforce training center and its Type One Infinity Two, which will be a 400-megawatt, fusion power plant using its stellarator fusion technology. Type One Energy completed its initial review design in May 2025.
“As the global epicenter of nuclear energy, Tennessee is building the workforce, infrastructure and regulatory framework needed to lead the next generation of nuclear innovation,” Lee said in the release. “By creating a clear path for emerging technologies like fusion, we’re advancing the reliable, abundant American energy we’ll need for generations to come.”
Type One Energy is based in Knoxville, Tenn. and has been working with TVA since 2024 and agreed to collaborate on developing a fusion power plant in February 2025.
