Google is set to purchase nearly 400 megawatts of enhanced geothermal power from Fervo Energy for a data center in Utah, according to reports. The deal is described as among the largest of its kind and is framed as a step toward securing long-term, dispatchable clean electricity for computing demand.

Both outlets say the agreement includes an option for Google to expand its power purchases to nearly 1 gigawatt. That expanded capacity would be sufficient to support a very large AI data center, the reports note, depending on site requirements and electricity use. The arrangement is presented as a milestone for enhanced geothermal, a technology designed to make geothermal resources more controllable through techniques such as engineered geothermal reservoirs.

While the sources align on the deal size, the Utah location, and the potential expansion, they differ slightly in emphasis. TechCrunch highlights the potential scale of up to 1 GW in relation to an AI data center, while Quartz focuses on the agreement’s positioning as the largest enhanced geothermal power purchase deal on record.
