Fervo Flips the Switch on Cape Station, World's First Utility-Scale Next-Gen Geothermal

Fervo Energy has brought the first utility-scale, next-generation geothermal power plant online anywhere in world, the Houston-based startup announced Thursday. The Cape Station facility in Beaver County, Utah, delivers enhanced geothermal systems (EGS) power to the grid, with Southern California Edison as its primary customer.

The milestone matters now because the U.S. faces what Fervo describes as an unprecedented demand surge for electricity, driven largely by the AI boom. Geothermal offers clean energy and reliable baseload power without the intermittency problems that plague wind and solar.

Bill Gates-backed Fervo, which went public in May with the biggest clean-energy IPO in history, combines traditional geothermal science with modern oil-drilling and hydraulic fracturing techniques. The approach lets the company build reservoirs and power plants wherever customers need them, rather than depending on the naturally occurring reservoirs that conventional geothermal— a technology dating back more than a century— requires.

"This is a gamechanger for the geothermal industry," Fervo co-founder and CEO Tim Latimer said in a statement Thursday. "It establishes EGS as the defining new power generation technology of our time, and we believe it shows that the commercial and technical maturity of EGS is ready to meet the urgent need for reliable, clean power."

"We are just getting started," he added.

Cape Station follows Fervo's initial pilot, Project Red, which went online in 2023.

The startup faces financial pressure to perform. Fervo's upsized May IPO pushed its market cap above $10 billion, but Wall Street enthusiasm cooled in the months that followed and the valuation plunged to roughly $5 billion. The company is betting Cape Station's startup will restart its upward trajectory.

The first phase of the plant is a 100-megawatt project— enough to power about 70,000 homes— built from three 33-megawatt "GeoBlocks." The first GeoBlock has just come online. Fervo says it will keep ramping up the first phase through the end of this year.

An additional 400 megawatts is under construction, with completion expected in 2028. A third phase would add another 400 megawatts, growing Cape Station into a 900-megawatt complex.

The engineering behind the plant is demanding. Fervo drills wells 10,000 feet deep— about two miles— then directionally drills horizontally another 7,500 feet to create reservoirs large enough to be productive. The company then fracks the rock to release flows of water naturally heated to more than 400 degrees. Utah, like much of the western U.S., offers a geographic advantage: the necessary heat sits at shallower depths than in most of the country.

The company's name comes from the Latin word meaning "to boil." Its technology uses underground-heated water to generate steam for electricity-producing turbines, then pumps the cooled water back into the subsurface to be reheated and recycled.

"Cape Station works because we treated the subsurface like an engineering challenge," said Jack Norbeck, Fervo co-founder and chief technology officer. "Years of drilling, completion design, subsurface modeling, and flow testing led to this moment, and this is the validation that matters most. First power is proof the science works."

The science may work. The next challenge, as Fervo acknowledges, is scaling next-gen geothermal until it is economically competitive with other power sources.
