Fervo's Utah Plant Becomes First New-Build Enhanced Geothermal Project to Reach Commercial Operation
The first 33-megawatt block of Cape Station was built in 23 months and began delivering power under contract one day early.
Geothermal energy just hit a milestone. On 1 October 2026, Fervo Energy announced that the first block of its Cape Station power plant in Beaver County, Utah, reached commercial operation on 30 September, one day ahead of its contractual deadline. The company says it is the first greenfield enhanced geothermal development to get there.
What was achieved
Enhanced geothermal systems drill deep, circulate water through hot rock and bring the heat to the surface, which opens up geothermal power beyond places with natural hot springs.
- Output: the first "GeoBlock" reached 33 megawatts of net power, meeting the production level required by its power purchase agreement.
- Grid connection: the plant synchronized with the grid on 24 September.
- Build time: 23 months from start to commissioning.
- Revenue: Fervo is now generating revenue under its contract.
CEO Tim Latimer called it a "turning point for the entire energy industry."
Why it matters
Geothermal can run around the clock, unlike solar and wind, which makes it attractive as steady, low-carbon power. Fervo says each new block should be faster to build than the last and aims to cut construction to 18 months.
"Every GeoBlock we bring online makes the next one faster and more predictable." — Dawn Owens, Fervo Energy
What's next
- Phase I totals about 100 megawatts across three 33-megawatt blocks. The two remaining blocks are in commissioning and are expected to reach commercial operation by 1 January 2027.
- A further 400 megawatts is under construction, targeted for 2028.
As with any company announcement, the milestone is Fervo's own account, and its forward-looking targets carry risks the company outlines in its filings. Still, a working commercial plant is a significant step beyond demonstration projects.
