World’s biggest geothermal power purchase agreement completed in western U.S.
A Utah geothermal project just secured what developers are calling the world’s largest geothermal power purchase agreement — a 15-year deal to deliver 320 megawatts of always-on clean electricity to Southern California Edison, enough to power roughly 350,000 homes. Fervo Energy’s Cape Station plant uses horizontal drilling borrowed from the oil and gas industry to circulate water through deep hot rock, unlocking geothermal power in places where it was never viable before. First electrons are expected to flow in 2026, with the rest coming online by 2028. For a clean grid that needs to run when the sun sets and the wind stops, this kind of steady, weather-proof power may be the missing piece — and a signal that geothermal is ready for prime time.
