Google-Backed Fervo Energy Achieves First Power at 900MW Cape Station Geothermal Plant in Utah

Fervo Energy has reached a landmark milestone in the commercialization of enhanced geothermal systems, achieving first power at its flagship Cape Station project in Beaver County, Utah. The achievement marks the first time a utility-scale enhanced geothermal project has delivered power anywhere in the world, signaling a potential turning point for a technology that has long held promise but struggled to reach commercial scale.

The Cape Station GeoCluster is being developed in phases. Phase I is slated to deliver 100MW of capacity across three 33MW GeoBlocks, the first of which has now achieved first power. Fervo said it will continue ramping up the initial GeoBlock as it brings the full well system online while commissioning the remaining two GeoBlocks, which are expected to reach commercial operations in January 2027. The next stage of the project, expected to add a further 400MW, is already under construction and targeted for completion in 2028. At full capacity, Fervo claims the project will have a power output of approximately 900MW.

The project is underpinned by a long-term power purchase agreement with Google signed earlier this year, under which the hyperscaler agreed to offtake 396MW of power from Cape Station. Google has backed Fervo since 2021, when the two companies partnered on a small-scale pilot project in Nevada that came online in 2023. They subsequently signed a 115MW PPA alongside utility partner NV Energy to deliver geothermal power into the Nevada grid. Google later led Fervo's Series B funding round, in which the company raised $462m, and in May, Fervo completed its initial public offering, achieving a valuation of $10bn.

Fervo is an Enhanced Geothermal Systems company that applies drilling techniques adapted from the hydraulic fracturing sector to access geothermal resources that are unreachable through traditional methods. By tapping deeper, hotter geological deposits, EGS systems offer substantially higher potential capacities and provide data center operators with a low-carbon baseload alternative to intermittent renewable sources. "Cape Station works because we treated the subsurface like an engineering challenge," said Jack Norbeck, CTO and co-founder of Fervo Energy. "Years of drilling, completion design, subsurface modeling, and flow testing led to this moment, and this is the validation that matters most. First Power is proof the science works."

The milestone carries broader implications for the data center industry, which has been aggressively seeking firm, clean power sources to support the rapid buildout of AI and cloud infrastructure. Google is not alone in turning to geothermal energy. Meta has signed offtake agreements with two EGS developers in the US, including a 150MW deal with Sage Geosystems for a project under development east of the Rocky Mountains and a 150MW agreement with XGS Energy for a project in New Mexico. Microsoft has also entered the space, signing a ten-year PPA with Contact Energy for 51MW in New Zealand and partnering with G42 on a data center in Kenya that will run exclusively on geothermal energy. As hyperscalers race to secure reliable carbon-free power, Fervo's achievement at Cape Station could accelerate the adoption of enhanced geothermal as a viable utility-scale resource.
