CFS becomes the first fusion company to apply to connect to PJM, the largest US grid market, for ARC

Commonwealth Fusion Systems/ARC

CFS filed a request to connect its planned 400 MW ARC plant, the Fall Line Fusion Power Station in Chesterfield County, Virginia, to PJM, the grid operator serving 65 million people in 13 states and DC. It is the first fusion company to do so; interconnection studies typically take 4 to 6 years, so filing now lines up with a grid date in the early 2030s.

• PJM Interconnection manages 182,000 MW of capacity across 13 states and DC, serving 65 million customers—the largest U.S. competitive wholesale electricity market.
• ARC's 400 MW plant is designed to deliver electricity in the early 2030s; interconnection studies typically require 4–6 years from filing to grid connection.
• CFS's early filing ensures grid infrastructure planning aligns with ARC's planned operational timeline, a critical first step for large generators.
