ARC (Fall Line Fusion Power Station)

Overview

CFS' first planned grid-scale commercial fusion power plant, designed to deliver about 400 MW of clean electricity using the HTS magnet and tokamak stack proven through SPARC. The project is officially named the Fall Line Fusion Power Station and is planned for a 100-acre site at the James River Industrial Center in Chesterfield County, Virginia.

Has not broken ground, but in April 2026 CFS became the first fusion company to file a grid interconnection request with PJM Interconnection, the largest U.S. wholesale electricity market. The plant is locked in with a 200 MW PPA from Google and a $1B+ offtake agreement with Eni; CFS still targets the early 2030s for first electricity delivery and a 20-year operating life.
