Helion begins work on Washington nuclear fusion plant

Helion says reactor could deliver power to data centres by 2028

Microsoft signed what it said was the world’s first power purchase agreement (PPA) for nuclear fusion in May 2023, with the company expected to offtake up to 50 MW of capacity following a one-year ramp-up period. Privately owned Helion, founded in 2013, has said the planned operational date for this “first of its kind” facility is significantly sooner than typical projections for deployment of commercial fusion power. The fusion firm still needs to secure the final permits from the state government to allow for the project's energisation, but said it remains on track to deliver power by 2028.
