Fervo Energy has signed a 396-MW geothermal power purchase agreement with Google, according to a September 1 report. The agreement is intended to supply power from the Cape Station Enhanced Geothermal Systems project in Utah for a potential Google data center by June 2030.
This agreement represents the largest enhanced geothermal power purchase agreement signed to date. Fervo Energy will supply power from the Cape Station project, which is expected to come online in 2028. Google has an option to expand its offtake by approximately 600 MW, which would bring the total to nearly 1 GW.
Google stated that final plans for the data center remain subject to several factors, including commercial conditions, local and state approvals, and engineering feasibility. The project aims to expand the Cape Station GeoCluster beyond its initial 100 MW phase through the use of repeatable 50-MW GeoBlock units designed to scale operations and reduce development costs.
The partnership between Fervo Energy and Google began with Project Red, a commercial pilot project in Nevada that began supplying power to the local grid in 2023. In 2024, Google entered an agreement to purchase 115 MW of geothermal power from Fervo through NV Energy.
Fervo Energy CEO and Co-Founder Tim Latimer stated that the agreement reinforces that enhanced geothermal systems are ready to power next-generation computing infrastructure. He noted that the PPA is part of a repeatable commercial model that delivers clean, firm power to large electricity users.
Lucia Tian, Google's Director of Advanced Energy Technologies, said the project is expected to drive economic benefit to the local community and help catalyze long-term energy cost reductions by making enhanced geothermal more accessible and affordable.
Fervo Energy closed a USD 462 million Series E financing round in late 2025, which included Google as an equity investor.
