Home Fusion Fusion Energy Group Seeks PJM Connection for First Commercial Power Plant
A U.S.-based fusion energy company has become the first such firm to apply to join a major power grid operator. Massachusetts-based Commonwealth Fusion Systems (CFS) on April 28 said it has submitted an application to connect its ARC power plant to PJM Interconnection, the nation’s largest wholesale electricity market.
CFS on Tuesday said the application marks the first time a fusion power plant developer has requested an interconnection with a power grid operator. PJM serves more than 65 million customers across 13 states and the District of Columbia. CFS, which has raised almost $3 billion in capital since it was founded in 2018, said it is on track to deliver electricity from fusion energy to the grid in the early 2030s. The power would be generated from the company’s planned 400-MW Fall Line Fusion Power Station (Figures 1 and 2) in Chesterfield County, Virginia.
“Our commitment to delivering the benefits of fusion, and enabling a future with abundant, secure energy, means that we’re not just proving fusion physics works—we’re showing exactly how fusion power plant watts get from our machine to the customer, working with the grid and a utility,” said Bob Mumgaard, co-founder and CEO of CFS. “By becoming the first fusion energy developer to enter a major grid operator’s interconnection queue, we’re demonstrating that when you’re serious about building a power plant in the early 2030s, you act now. This is execution.”

CFS on Tuesday said the power plant’s name, also announced today—it previously had been known simply as ARC, for affordable, robust, compact—references the geological boundary where Virginia’s elevated Piedmont region drops down to the Tidewater coastal plain. The location creates rapids on the James River. CFS said the site historically has been where “Virginians built mills at the Fall Line to harness the power of falling water … today, CFS will harness a different energy source: the clean, safe, secure power of fusion.”
Virginia officials had announced the site of the power plant in late 2024, saying it would be built on 100 acres at the James River Industrial Park in Chesterfield County (Figure 3).

CFS said that as part of the application submission procedure, the company will work through PJM’s “diligent stress-test process to demonstrate that it can reliably help to meet the region’s surging energy demands.” The company said the plant is being eyed as a resource to meet the increasing energy demands of artificial intelligence-driven data centers in the region, which is part of Virginia’s so-called “Data Center Alley.” The area is known for its concentration of...
