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.
Site selected at James River Industrial Center in Chesterfield County, Virginia. CFS said in April 2026 that it has not yet broken ground, while first operation remains targeted for the early 2030s.
