Commonwealth Fusion Systems (CFS) has long been the best-funded fusion power startup.
CFS is currently building Sparc, its demonstration reactor, and finalizing the design of Arc, its first commercial power plant.
CFS hasn’t disclosed either Sparc’s or Arc’s price tag, though in 2024, Virginia’s former governor Glenn Youngkin said that Arc would be a “multi-billion-dollar fusion power plant.”
The company has made significant progress on its Sparc reactor, which it now expects will achieve scientific breakeven in 2027.
Alongside work on Sparc, CFS has been finalizing the design for Arc, the commercial-scale power plant planned for Virginia.
