Helion is expected to have its fusion generation device online by 2028 and to reach its target power generation of 50 megawatts or more within an agreed-upon one-year ramp up period. When the fusion device is fully up to speed producing 50 megawatts of energy, it will be able to power the equivalent of approximately 40,000 homes in Washington state.

While Helion’s deal with Microsoft is to get 50 megawatts online, the company eventually aims to produce a gigawatt of electricity, which is one billion watts, or 20 times the 50 megawatts it is selling to Microsoft.

Microsoft will pay for the megawatt hours of electricity as Helion delivers them to the grid.
