The AI Transformation 100: Concrete Ideas for Fixing How We Work
- Fervo Energy raised $1.89 billion in its IPO, giving the geothermal startup an initial valuation of about $7.7 billion.
- The company’s stock opened 33% above its IPO price, signaling strong investor interest in next-generation geothermal power.
- Fervo is building a major Utah geothermal plant that is expected to supply clean, 24/7 electricity to customers including Google and Southern California Edison.
- Enhanced geothermal still faces major questions around cost, well performance, seismic risk and whether demand from AI data centers will keep rising.
Fervo Energy raised nearly $1.9 billion in its initial public offering, giving the Houston-based geothermal startup fresh capital as electricity demand from AI data centers, utilities and industrial customers accelerates.
The company sold 70 million shares at $27 each, raising $1.89 billion and giving Fervo an initial valuation of roughly $7.7 billion. Shares began trading Wednesday on the Nasdaq at $36, 33% above the offering price, and closed at $36.54.
The strong debut gives Fervo a major boost as it works to turn next-generation geothermal power from a niche clean energy source into a scalable part of the US electricity grid.

Fervo Taps Wall Street Demand for Clean, 24/7 Power
Fervo’s IPO comes as investors show growing interest in energy technologies that can provide steady, low-emissions electricity.
Unlike wind and solar, geothermal plants can operate around the clock. That has made the technology more attractive as utilities and technology companies search for power sources that can support surging demand from AI data centers.
Fervo CEO Tim Latimer said the IPO gives the company the funding needed to accelerate its growth plans.
“The exciting thing for us is this has now infused us with the capital needed to actually grow at the pace we’ve always wanted to, to grow in terms of putting gigawatts on the grid and solving this energy challenge,” Latimer told the New York Times.
How Fervo’s Geothermal Technology Works
Traditional geothermal power plants rely on naturally occurring underground reservoirs of hot water, which limits the technology to certain regions. Fervo is part of a newer group of companies trying to expand geothermal by applying drilling methods borrowed from the oil and gas industry.
The company drills pairs of deep wells into hot, dry rock. It then creates cracks between those wells using controlled explosives and high-pressure fluids. Water is injected into one well, moves through the heated rock, then returns through the other well as steam hot enough to turn turbines and generate electricity.
The approach is designed to make geothermal viable in far more places than conventional geothermal systems.
Utah Plant Could Become Fervo’s First Major Test
Fervo is building its first commercial power plant in Utah. The project, called Cape Station, is expected to begin sending electricity to the grid this year.
When fully built, Cape Station is expected to generate at least 500 megawatts of electricity. Fervo has already signed agreements to sell power from the project to customers including Google and Southern California Edison.
The company says it has leased land with the potential to support more than 40,000 megawatts of geothermal capacity. For comparison, the US currently has about 3,800 megawatts of conventional geothermal capacity, mostly in the West.
AI Data Centers Add Urgency to the Power Search
Fervo’s market debut lands at a moment when technology companies need to secure more electricity for AI infrastructure.
Data centers are driving a major increase in power demand across the US, pushing companies and utilities to invest in a wide mix of energy sources, including:
- Solar power
- Battery storage
- Natural gas plants
- New nuclear technologies
- Advanced geothermal systems
Geothermal has drawn support across political lines because it offers clean electricity that does not depend on weather conditions. The Trump administration has also backed the sector, recently announcing $171.5 million for geothermal field tests.
Cost and Field Performance Remain Major Questions
Despite the enthusiasm, enhanced geothermal still faces significant technical and economic hurdles.
Fervo said in its IPO filing that Cape Station would cost about $7,000 per kilowatt of electricity produced. That would make it less expensive than new nuclear power, but still more than twice as costly as a natural gas plant. Costs, however, could fall as companies improve drilling efficiency and optimize wells, similar to the cost declines seen in oil and gas development.
But long-term well performance remains a key unknown. One major question is how quickly geothermal wells cool as water moves through them. If wells cool too quickly, companies may need to drill replacements, raising costs and complicating project economics.
Environmental concerns could also slow the industry. Critics have raised questions about whether enhanced geothermal drilling could increase seismic risks or threaten groundwater.
Fervo Still Faces a Competitive and Unproven Market
Fervo has yet to turn a profit, and its IPO filing noted several risks that could affect future growth. Those include the possibility that data centers may use less power than expected or that customers could choose competing technologies such as nuclear reactors.
The company is also entering a market where larger and more established geothermal players already operate. Ormat Technologies, based in Reno, Nev., is currently the leading geothermal power plant developer and operator in the US. Investors value Ormat at about $7.5 billion, slightly below Fervo’s initial valuation, though Ormat also operates waste heat and energy storage businesses.

Other startups are also trying to expand geothermal’s reach. Sage Geosystems is developing systems that use fractured wells to store and generate electricity. Eavor Energy is building a closed-loop geothermal system in Germany. Controlled Thermal Resources is developing a geothermal project at California’s Salton Sea and is planning an IPO later this year.
