U.S. state regulators, Type One Energy, and the Tennessee Valley Authority have submitted a “byproduct material license” application in preparation for Tennessee’s first commercial fusion project. In July 2025, TVA and Type One Energy signed the first set of commercial contracts related to Project Infinity, which is developing fusion power plant technology to supply the Tennessee Valley with energy by the mid-2030s.
TVA is using its Power Service Shops in Muscle Shoals, Alabama to help develop welding and fabrication techniques for Project Infinity. The manufacturing and construction methods will be used for one stellarator machine that is currently deployed at TVA’s Bull Run Fossil Plant near Knoxville. They will also be used for a subsequent fusion power plant project which utilizes Type One Energy’s Infinity Two stellarator technology, whose first formal design was completed in June.
“TVA is proud to play a leading role in supporting the advancement of fusion energy—a technology that represents the next frontier in low-cost, reliable power,” said Don Moul, TVA President and CEO. “Our collaboration with Type One Energy and the State of Tennessee highlights how innovation and partnership can strengthen America’s energy security and advance the nation’s commitment to energy leadership. Through initiatives like Project Infinity, TVA is helping ensure that the Tennessee Valley remains at the forefront of delivering prosperity for American families.”
