A field-reversed-configuration fusion generator whose first plant is contracted to sell electricity.
What it changes
Sells power rather than machines: a buyer signs for electricity from Helion’s own plant instead of funding a reactor build.

Access and cost
Get Helion Polaris — Power pricing is not published; Helion contracts electricity directly rather than selling reactors to customers.
Evidence it works
- Announced a power purchase agreement with Microsoft and Constellation for electricity from its first fusion plant. — source
- Described the Microsoft agreement as the world’s first fusion energy purchase agreement when it was announced in May 2023. — source
What it cannot do yet
- Delivery depends on the plant reaching operation, and contracted fusion dates have not yet been met by any company.
- Nothing is purchasable today: no price list, no order path and no product beyond contracted power.
