TemasekEquinorDevonshire InvestorsCommonwealth Fusion Systems is an American fusion power company founded in 2018 as a spin-off from the MIT Plasma Science and Fusion Center, headquartered in Devens, Massachusetts. It is building the SPARC tokamak using high-temperature superconducting magnets made from a proprietary tape called VIPER, technology meant to let fusion reactors shrink to a commercially viable size.
The company plans a grid-scale ARC power plant in Chesterfield County, Virginia, expected to produce about 400 megawatts by the early 2030s, and has signed a direct corporate power purchase agreement with Google for 200 megawatts of that plant's output.
