Fusion energy manufacturing just crossed a regulatory threshold no company had ever reached. On June 16, 2026, Helion Energy became the first company in the world to receive state licenses to build and operate a fusion power plant.
Key Takeaways
- Helion Energy became the first company in the world to receive regulatory licenses to build and operate a fusion power plant on June 16, 2026
- The Washington State Department of Health issued two licenses: a Radioactive Materials License and a Radioactive Air Emissions License for the Orion facility in Malaga, WA
- Helion targets delivery of 50 megawatts of fusion-generated electricity to Microsoft by 2028 under an existing power purchase agreement
- The company raised $465 million in a Series G round in June 2026 at a $15.5 billion valuation, led by Thrive Capital; total funding now stands at approximately $1.5 billion
- Unlike nuclear fission, fusion produces no long-lived radioactive waste and carries no meltdown risk; the fuel source is abundant hydrogen isotopes
What the Helion Licenses Actually Mean for Fusion Energy
Regulatory licenses for a fusion power plant have never been issued before. That fact alone makes the June 16 announcement a milestone. The Washington State Department of Health issued two licenses: a Radioactive Materials License and a Radioactive Air Emissions License. Together, they confirm that Helion has the facilities, trained personnel, and safety programs needed to meet rigorous state regulatory standards, and they clear the path for continued construction on the generator building at Orion, where initial earthwork began in the spring of 2026. The assembly and office building is already complete. The generator building is the next major construction phase, and it could not proceed without the licensing milestone now in hand.
Why Permitting Matters as Much as Physics
The technical challenge of fusion has dominated the industry’s public narrative for decades. The regulatory challenge has received far less attention, and it is equally significant. A fusion company that achieves scientific milestones but cannot navigate permitting cannot deliver commercial power. In effect, Helion has now demonstrated progress on both tracks simultaneously: active construction and regulatory clearance.
Fusion vs. Fission: What Manufacturers Need to Know
Nuclear fission, which powers today’s commercial nuclear plants, works by splitting heavy atoms apart. That process releases large amounts of energy but also produces radioactive waste that remains hazardous for thousands of years. It also carries meltdown risk in the event of a cooling system failure.
Fusion is the opposite process. It combines light atoms together, specifically hydrogen isotopes, and releases energy through the same mechanism that powers the sun. The fuel inputs are abundant. A few grams of hydrogen isotopes can produce energy equivalent to thousands of gallons of oil. Fusion produces no long-lived radioactive waste. There is no chain reaction to sustain, so there is no meltdown risk.
The challenge has always been containment. Recreating the conditions of the sun’s core requires plasma temperatures exceeding 100 million degrees Celsius. Helion’s Polaris machine has already exceeded 150 million degrees Celsius, setting a private fusion record in the process.
Inside the Orion Facility in Malaga, Washington
Helion began construction at the Orion site in Malaga, Washington, in July 2025. The facility is designed to produce 50 megawatts of fusion-generated electricity. Malaga is a small community in Chelan County, in central Washington State, near the Columbia River Basin. The region has a history of industrial energy production and is proximate to the Microsoft data center operations Helion has contracted to supply.
As of June 2026, the assembly and office building construction is complete. The generator building earthwork is underway following the licensing clearance. The target is to be online by 2028, which would make Orion the world’s first commercial fusion power facility.
The Microsoft Power Purchase Agreement
Helion holds a power purchase agreement with Microsoft to deliver at least 50 megawatts of fusion electricity by 2028. The power is destined for a central Washington data center. The agreement is the first power purchase contract for fusion energy ever signed. For Microsoft, it is part of a broader clean energy commitment for its AI and cloud infrastructure. For Helion, it is a defined commercial obligation that the Orion timeline must satisfy.
The Capital Behind Helion’s Fusion Bet
In June 2026, Helion raised $465 million in a Series G round led by Thrive Capital. Additional investors include Alta Park Capital, Lux Capital, Peak XV Partners, and Ford Motor Company Executive Chairman Bill Ford. The round values Helion at $15.5 billion post-money, nearly triple its previous valuation of $5.43 billion in January 2025. Total funding in the company now stands at approximately $1.5 billion.
The capital will support serial production scale-up, expanded manufacturing capacity for fusion components, and continued construction at Orion. Notably, the round attracted participation from Ford’s executive chairman, a signal that manufacturers in energy-intensive industries are paying attention to fusion as a potential power source.

Frequently Asked Questions
What regulatory licenses did Helion Energy receive?
The Washington State Department of Health issued two licenses to Helion on June 16, 2026: a Radioactive Materials License and a Radioactive Air Emissions License. These are the first regulatory licenses ever issued for a fusion power plant. They confirm that Helion has the facilities, trained personnel, and safety systems needed to operate the Orion facility, and they clear the path for continued construction on the generator building.
Where is Helion’s Orion facility?
The Orion facility is located in Malaga, Washington, in Chelan County in central Washington State. Construction began in July 2025. As of June 2026, the assembly and office building is complete and earthwork on the generator building is underway.
What is the difference between fusion and fission?
Nuclear fission splits heavy atoms apart to release energy. It produces long-lived radioactive waste and carries meltdown risk. Fusion combines light atoms together, specifically hydrogen isotopes, releasing energy through the same process that powers the sun. Fusion produces no long-lived radioactive waste, carries no meltdown risk, and uses fuel inputs that are effectively limitless.
What is Helion’s deal with Microsoft?
Helion holds a power purchase agreement with Microsoft to deliver at least 50 megawatts of fusion electricity by 2028. The power is destined for a central Washington data center. It is the first power purchase contract for fusion energy ever executed. Microsoft signed the agreement as part of its commitment to clean energy for AI and cloud infrastructure.
How much funding has Helion raised?
Helion has raised approximately $1.5 billion in total funding. The most recent round was a $465 million Series G in June 2026 led by Thrive Capital, which valued the company at $15.5 billion post-money. That valuation is nearly triple the company’s January 2025 figure of $5.43 billion.
What would it mean for manufacturers if fusion energy becomes commercially viable?
Commercial fusion power would offer manufacturers a source of clean, baseload electricity without the fuel cost volatility of natural gas or the intermittency of solar and wind. Energy-intensive industries, including steel, chemicals, aluminum, and data center infrastructure, would gain access to a power source with near-limitless fuel, no carbon emissions, and no long-lived radioactive waste. If Helion delivers on its 2028 timeline, it would be the first credible proof of concept for commercial fusion at scale.
Bottom Line: Fusion has been described as perpetually 20 years away. For the first time, a fusion company has regulatory licenses, active construction, a signed power purchase agreement, and $1.5 billion behind it. Whether Helion meets its 2028 timeline is an open question. That it has reached this point is not. For manufacturers tracking the long-term energy landscape, the Orion facility in Malaga is the most important construction site in the country right now.
