Next-gen geothermal raises $462M as Cape Station heads to the grid

Geothermal energy has long been clean and reliable but limited to a few volcanic regions. Enhanced geothermal systems aim to change that by drilling deep and circulating water through hot rock almost anywhere. On December 10, 2025, Fervo Energy, a leading developer of this next-generation approach, announced it had closed an oversubscribed $462 million Series E round to accelerate its flagship project.

The round was led by new investor B Capital, with participation from Google, Mitsui & Co., AllianceBernstein, Atacama Ventures, Carbon Equity, Climate First and Holtec International founder Dr. Kris Singh, alongside returning backers including Breakthrough Energy Ventures and CalSTRS. The funding targets Cape Station in Beaver County, Utah, which Fervo describes as the largest next-generation geothermal development in the world.

“Enhanced geothermal systems aim to change that by drilling deep and circulating water through hot rock almost anywhere.”

Cape Station is set to begin delivering 100 megawatts of firm, carbon-free power to the grid in 2026, with an additional 400 megawatts coming online by 2028 for a total of 500 megawatts. Unlike solar and wind, geothermal supplies steady baseload power day and night regardless of weather, making it valuable as electricity demand climbs from data centers and electrification. CEO Tim Latimer said energy markets are demanding dependable, carbon-free power at unprecedented scale.

The caveats are real. Enhanced geothermal is still a young commercial technology, and large projects can face drilling challenges, cost overruns and induced-seismicity concerns that must be carefully managed. Delivering the full 500 megawatts on schedule through 2028 is an engineering and financing test, not a certainty. Even so, a major funding round backed by experienced energy and technology investors is a strong signal that next-generation geothermal is becoming bankable. If Cape Station performs as planned, it could help prove that clean, always-on power is achievable far beyond the handful of regions where geothermal has traditionally worked.
