Fervo Energy's Utah geothermal plant starts selling power to the grid
Fervo Energy, a Houston-based geothermal startup, is now selling power to the grid from its Cape Station project in Utah. The article, originally published by Canary Media, describes this as the first time a utility-scale, next-generation geothermal facility has done so anywhere in the world.
The company turned on an initial 33-megawatt unit late last week and has been testing and ramping up output since. On Thursday, Fervo will officially begin commercial operations, supplying carbon-free electricity to Shell Energy, a retail power provider in California.
Cape Station is a $2 billion project that will eventually reach 500 MW. What sets it apart is the resource. Other commercial geothermal plants draw on naturally occurring hot water and steam; Fervo has engineered its own geothermal resource deep underground, using drilling techniques from the oil and gas industry to create reservoirs in hot, dry rock that generate steam to produce electricity. Dawn Owens, Fervo's senior vice president and head of development and commercial markets, says traditional geothermal would never have been done in southern Utah.
The build-out has a schedule. Fervo says it is working to commission two more 33-MW power blocks by 1 January, 2027. The remaining 400 MW, which is supported by a new agreement with Google, is under construction and slated to come online in 2028.
Fervo already operates a 3.5-MW commercial pilot plant in Nevada, called Project Red, which went online in late 2023. Owens says the pilot was important for demonstrating the technology, while Cape Station proves the approach can reach utility scale and export power to wider markets. Fervo went public in May, and the article places it at the head of a fast-growing push for clean, always-on geothermal power to meet soaring data center demand and balance intermittent solar and wind. Next-generation geothermal firms have raised billions of dollars in private capital in recent years.
The context is modest: geothermal supplies just 0.4 percent of total U.S. electricity generation each year. Experts say growing that share will take more projects like Cape Station, plus tackling high upfront drilling costs and other economic and regulatory barriers, while limiting potential impacts on communities and the environment. Mitchell Smith, grid lead for the Mountain West Geothermal Consortium, says the first power shows investors the size of the opportunity. The bipartisan initiative is calling for more public and private financing.
On economics, Fervo has declined to disclose the terms of its power purchase agreements for in-progress and future development, which together total about 1,000 MW, or enough for roughly 1 million U.S. homes a year. The company previously told Canary Media that Phase 1 of Cape Station is set to deliver power at $7,000 per kilowatt and Phase 2 at $5,500 per kilowatt. For comparison, the average cost to build a natural gas-fired power plant was $2,157 per kilowatt in 2025. Researchers say enhanced geothermal projects could improve their economics by cutting drilling costs and by delivering power when it is most valuable, for example in the evening when solar output falls. Owens adds that geothermal plants could run behind the meter to power data centers directly, so the cost of new capacity is not passed on to utility customers.
Key facts
- Fervo Energy turned on an initial 33-MW unit at Cape Station in Utah and is selling power to the grid; the article calls it a world first for a utility-scale, next-generation geothermal facility.
- Commercial operations officially begin on Thursday, supplying carbon-free electricity to Shell Energy, a retail power provider in California.
- Cape Station is a $2 billion project planned to reach 500 MW: two more 33-MW blocks by 1 January, 2027, and the remaining 400 MW, backed by a new Google agreement, in 2028.
- Fervo engineers its own underground reservoirs using oil and gas drilling techniques, rather than relying on naturally occurring hot water and steam.
- Fervo declined to disclose its power purchase agreement terms; it previously gave Canary Media figures of $7,000 per kilowatt (Phase 1) and $5,500 per kilowatt (Phase 2), against $2,157 per kilowatt for the average gas plant built in 2025.
Why it matters
According to the article, this is the first time a utility-scale, next-generation geothermal facility has sold power to the grid anywhere in the world. Fervo's earlier plant, the 3.5-MW Project Red in Nevada, showed the technology worked; Cape Station, with an initial 33-MW unit and 500 MW planned, is about showing it can scale. Geothermal supplies only 0.4 percent of U.S. electricity, and the article frames the engineered approach as a way to serve growing data center demand and to complement intermittent solar and wind. Owens calls the milestone massive for Fervo and the geothermal industry at large.
Who it affects
Shell Energy, a retail power provider in California, is the first buyer of Cape Station's carbon-free electricity. Investors and other geothermal developers are another audience: Mitchell Smith of the Mountain West Geothermal Consortium says the first power shows the size of the opportunity for many more projects, and the consortium is calling for more public and private financing. Data center operators are a third group, since the article cites data center demand as a driver and Owens suggests behind-the-meter plants could power them directly. Utility customers are named too: that arrangement is meant to keep the cost of new capacity from being passed on to them.
How to use it
This is not a product readers can adopt; it is a power plant selling electricity through Shell Energy. The practical use is as a set of milestones to track: official commercial operations on Thursday, two more 33-MW blocks targeted by 1 January, 2027, and the remaining 400 MW slated for 2028. Another thing to watch is whether the flexible operation researchers describe, running in the evening when solar output declines, or the behind-the-meter data center model Owens describes, turns into actual deployments.
How solid is it
The article is a single account republished from Canary Media, and the quotes about the milestone come mainly from a Fervo executive, Dawn Owens, with one supportive voice from the Mountain West Geothermal Consortium. The world-first framing is the article's own, and the capacity figures, schedule and cost numbers come from the company. The article says the 33-MW unit has been testing and ramping up output; it does not say full output has been reached. The power purchase agreement terms are not disclosed, and the size and terms of the Google agreement are not stated beyond it supporting the remaining 400 MW.
Risks and caveats
Cost is the first caveat. The company's previously stated figures of $7,000 per kilowatt for Phase 1 and $5,500 for Phase 2 sit against $2,157 per kilowatt for the average gas plant built in 2025, though the article does not say exactly what the Fervo figures measure. Experts say wider growth depends on tackling high upfront drilling costs and other economic and regulatory barriers, while limiting potential impacts on communities and the environment. The article gives no assessment of induced seismicity, earthquake risk or environmental impact of the engineered reservoirs. Flexible operation is described only as something next-generation facilities might do, per researchers. The 2027 and 2028 build-out dates are targets, not achieved results.
