Helion begins building first fusion power plant

Helion has begun site work and construction activities on the Orion fusion power plant site in Malaga, Washington, leasing land from Chelan County PUD and proceeding after an MDNS under SEPA.

• Main action: Helion began building on the Orion site in Malaga, Washington on land leased from Chelan County Public Utilities District (PUD); the project follows a Mitigated Determination of Non-Significance (MDNS) under Washington’s SEPA environmental review and remains on track to deliver electricity to Microsoft by 2028 under the 2023 PPA, with Constellation Energy serving as power marketer.
• Background & technical details: Helion is pursuing rapid iteration with prototypes: the 7th-generation Polaris is expected to demonstrate the first electricity produced from fusion, and prior prototype Trenta achieved a fuel temperature of 100 million degrees Celsius; Helion has engaged local and state stakeholders, Tribal Nations, and the public during siting and permitting and will continue remaining permitting steps to construct and operate the commercial plant.
