Fervo Energy Begins Commercial Power Sales from Cape Station Geothermal Plant

Fervo Energy has begun selling electricity from its Cape Station power plant to the electrical grid, marking the first time an enhanced geothermal company has achieved commercial power delivery. The company announced Thursday that commercial sales began on September 30, 2026, one day ahead of its scheduled target, as reported by TechCrunch .

The Cape Station plant synchronized with the grid roughly a week prior to commercial sales, activating the first third of what is planned to become a 100-megawatt generating facility. The broader project location has the capacity to eventually generate up to 4 gigawatts of electricity across future buildouts, Fervo previously told TechCrunch.

Construction on the initial block at Cape Station spanned 23 months from groundbreaking to commercial operations. Fervo aims to shorten future block completion times to 18 months as it streamlines subsurface engineering and drilling workflows.

"No team has ever built a project like this anywhere in the world, and we did it ahead of schedule," Fervo co-founder and CEO Tim Latimer said in a statement.

The operational milestone comes as data center developers seek firm clean electricity to support computing workloads. Enhanced geothermal systems can be built in sequential phases, mirroring the phased expansion of data center campuses. Fervo has already signed commercial power purchase agreements for Cape Station with customers including Google and Southern California Edison.

Unlike conventional geothermal systems that rely on naturally occurring steam reservoirs near the surface, enhanced geothermal operators drill deeper into hotter subterranean rock formations. Founded in 2017, Fervo applies horizontal drilling techniques borrowed from the oil and gas sector to extract heat. Before raising $1.9 billion in an upsized initial public offering in May, the company raised more than $1.3 billion in private capital from investors including Breakthrough Energy Ventures, Congruent Ventures, and Capricorn Investment Group.
