Commonwealth Fusion Systems said Tuesday it has formally filed a request with grid operator PJM to connect its planned power plant in Virginia.
Why it matters: It's the first time a fusion developer has filed one of these detailed requests to link to a major grid region, Commonwealth said.
- This step isn't just box-checking to get on a waiting list, but rather the result of discussions with the grid operator going back over a year.
- It will bring even more detailed work in coming years as PJM vets what Commonwealth hopes will be commercial power generation in the early 2030s.
The big picture: The company cast the grid interconnection request as a bridge from the science phase of fusion to the real world.
- "It's a rigorous process, where you document what it will look like to the grid operator, how it will run, how it will start up, how it will shut down, all the details that go into an operating power plant," Commonwealth CEO Bob Mumgaard said in an interview.
Zoom out: Commonwealth is among the furthest along of the startups looking to commercialize fusion power — a prospect that remains fraught with technical and financial uncertainties.
- It's working with utility partner Dominion Energy and hopes to generate 400 megawatts from a fusion reactor called ARC near Richmond.
- Commonwealth already has a power purchase agreement with Google for half the output.
The bottom line: Making fusion reality is about learning curves that go beyond the core science — and this is a piece of the puzzle.
