Tennessee Valley Authority, the federally owned utility, announced a public-private partnership Tuesday to develop a nuclear fusion power plant by the mid-2030s as investors show more interest in the technology.
The agreement is part of the broader “Project Infinity” established in 2024 that includes TVA, Knoxville fusion startup Type One Energy and the Department of Energy’s Oak Ridge National Laboratory. Originally focused on testing Type One’s Infinity One prototype at TVA’s decommissioned Bull Run coal plant in Tennessee, the new phase seeks to also develop and commercialize fusion technology.
That includes exploring a potential Infinity Two, a 350-megawatt commercial fusion plant that would power the equivalent of roughly 315,000 homes.
If approved by the TVA board, that could set up a race against Virginia’s Dominion Energy utility and Massachusetts-based Commonwealth Fusion Systems, which announced plans in December to build the world’s first commercial fusion plant “in the early 2030s.”
