Partnering with Dominion Energy Virginia, CFS independently finances, builds, owns, and operates the ARC fusion power plant, expected to generate 400 MW of clean electricity, enough to power about 150,000 homes. The project will create hundreds of jobs and contribute billions to regional economic growth. This follows progress on SPARC, CFS’s fusion demonstration machine under development in Massachusetts, expected to achieve its first plasma by 2026 and demonstrate net fusion energy, paving the way for ARC’s commercial operation in the early 2030s.

• August 2, 2024 – Helion Energy, a U.S.-based fusion technology company, secured a Large Broad Scope licence from the Washington State Department of Health (DOH) to operate its 7th-generation fusion machine, Polaris. The licence authorizes Helion to possess and use byproduct materials essential for fusion operations, marking a major regulatory milestone. Polaris, featuring stronger magnets and pulsing up to 100 times faster than its predecessor Trenta, aims to demonstrate electricity generation in 2024. This follows the U.S. NRC’s 2023 decision to regulate fusion separately from fission under the ADVANCE Act, empowering states like Washington to oversee fusion activities. Helion’s progress reinforces its mission to deliver safe, clean, and limitless fusion energy for a sustainable future.
