ARC is CFS's planned first commercial ~400 MWe tokamak power plant on a Dominion Energy-owned site in Chesterfield County, Virginia. It has a county conditional use permit, a PJM interconnection request filed in April 2026, and offtake deals with Google (200 MW) and Eni; power is targeted for the early 2030s.
