Fervo Energy announced that its Cape Station enhanced geothermal power plant in Utah began delivering electricity to the grid on September 30, one day ahead of schedule. The company said that from groundbreaking to commercial operations, the first block at the site took just 23 months to complete, marking the world’s first enhanced geothermal facility to reach this commercial milestone. This initial block provides one‑third of the planned 100‑megawatt capacity.
Unlike traditional geothermal, which taps heat near the surface, enhanced geothermal involves drilling into deeper, hotter rock, a technique Fervo adapted from the oil and gas industry. The company has said the entire site could eventually generate as much as 4 gigawatts of electricity, and that future blocks could be completed in as little as 18 months as the process is refined. Google, Southern California Edison and other customers have already agreed to purchase power from the Cape Station project.

For now, only the first third of the planned capacity is online, and the full 4‑gigawatt potential remains contingent on building out additional blocks. Fervo noted that achieving the full scale will depend on continued drilling and reservoir management, and it has not yet disclosed a timeline for completing the remainder of the plant.
