Google Signs Largest Geothermal Deal Ever for AI Power

Artificial intelligence is transforming our world, but it needs massive amounts of power to run. Now Google has found a way to fuel that future with clean energy pulled straight from deep underground.

The tech giant just signed a 396-megawatt power purchase agreement with Fervo Energy, a company that's perfected a new way to tap geothermal heat almost anywhere. This marks the largest enhanced geothermal deal ever signed, and it could grow to nearly 1 gigawatt by June 2030.

Traditional geothermal energy only works in specific locations near volcanoes or tectonic boundaries. Fervo's Enhanced Geothermal Systems technology changes that by using horizontal drilling to reach hot rock deep underground, creating clean power wherever they can drill deep enough.

Google and Fervo have been partners since 2021, when they launched Project Red to prove the technology worked. Last June, they signed a 115-megawatt agreement, and now they're scaling up dramatically with this new deal.

The energy will come from Fervo's Cape Station development in Utah, with power expected to flow by 2028. Phase I will deliver around 100 megawatts starting later this year or early 2027, followed by Phase II's 400 megawatts in 2028.

The Ripple Effect

This partnership solves two problems at once. Tech companies desperately need reliable power for their AI data centers, but they don't want to burden everyday people with higher electricity bills or contribute to climate change.

Geothermal energy runs 24/7, unlike solar or wind power that depends on weather conditions. This makes it perfect for data centers that never sleep.

Fervo raised $2.2 billion when it went public in May, giving it the cash needed to build out this ambitious project. The company plans to spend $850 million to $900 million over the next year expanding its infrastructure.

The agreement brings Fervo's total contracted power sales to about 1.1 gigawatts. By using modular 50-megawatt generation blocks, they can mass-produce components and cut manufacturing costs while building multiple blocks simultaneously.

What makes this deal truly special is how it protects regular ratepayers. Earlier agreements included provisions to shield everyday electricity customers from covering the costs of new development.

As AI continues to advance, finding clean, reliable power sources becomes more critical every day, and this partnership shows that solutions exist that benefit both technology and the planet.
