Fervo Signs Record 396MW Geothermal Deal With Google

Fervo Energy has signed what it describes as the world's largest enhanced geothermal power purchase agreement, securing a deal to supply Google with 396 megawatts of carbon-free electricity from its Cape Station project in southwestern Utah. The agreement, announced on September 1, 2026, includes an option for Google to expand its power purchases to nearly 1 gigawatt by mid-2030. Deliveries are scheduled to begin in 2028.

The deal marks a significant milestone for enhanced geothermal technology, which uses techniques like horizontal drilling and hydraulic fracturing to create geothermal reservoirs in hot rock, rather than relying on naturally occurring steam vents. This approach allows for geothermal power generation in a much wider range of locations. Fervo's Cape Station is intended to become the world's largest enhanced geothermal facility, with a potential capacity of 4.3 gigawatts.

Google plans to use the electricity to support a future data center in Utah, though the specific site has not yet been determined and requires regulatory approvals. The company is seeking reliable, around-the-clock clean energy to meet the surging power demands of its artificial intelligence...
