From SPARC to ARC: CFS prepares for a first-of-a-kind fusion plant
Commonwealth Fusion Systems makes no small plans. The company wants to build a 400-MWe magnetic confinement fusion power plant called ARC near Richmond, Va., and begin operating it in the early 2030s. And the plans don’t end there. CFS wants to deploy “thousands” of fusion power plants capable of accelerating a global energy transition.
