About Commonwealth Fusion Systems
Commonwealth Fusion Systems is the world's largest private fusion energy company. It is building SPARC, a compact tokamak in Devens, Massachusetts that uses high-temperature superconducting magnets and is designed to produce more power than it consumes. SPARC paves the way for ARC, a 400 megawatt commercial power plant planned for Chesterfield County, Virginia that is expected to put electricity on the grid in the early 2030s. The company plans to make money by selling electricity from its fusion power plants and has already signed offtake agreements with Google and Eni for power from the first ARC plant. CFS was spun out of MIT's Plasma Science and Fusion Center in 2018 and has raised $4 billion, more than any other private fusion company.
