Google Buys 400 MW Geothermal Power from Fervo

Google has secured a significant supply of enhanced geothermal energy by agreeing to purchase 400 megawatts (MW) from Fervo Energy. This agreement, announced on March 14, 2024, includes an option for Google to expand the purchase to 1 gigawatt (GW) of geothermal power. The substantial energy capacity from this deal is intended to power a very large AI data center located in Utah. This transaction marks another notable development for Fervo Energy, a company specializing in advanced geothermal technology, and underscores the growing interest in clean and reliable energy sources to meet the escalating demands of artificial intelligence infrastructure.

Fervo Energy utilizes a closed-loop system that circulates a working fluid through underground reservoirs to generate heat, which is then used to produce electricity. This approach differs from traditional geothermal power plants, which rely on naturally occurring hydrothermal resources. The company's technology aims to unlock geothermal energy potential in a wider range of geological locations, making it a more scalable and consistent renewable energy source compared to intermittent sources like solar and wind. The partnership with Google, a major consumer of electricity for its extensive data center operations, highlights the viability and attractiveness of enhanced geothermal systems for large-scale industrial applications.

The 400 MW capacity is substantial, representing a significant portion of Fervo's current and planned output. If Google exercises its option to increase the purchase to 1 GW, it would represent one of the largest single geothermal power agreements globally. For context, 1 GW is equivalent to 1,000 MW, enough to power hundreds of thousands of homes. The specific AI data center in Utah that this power is slated to support is a critical component of Google's expanding AI capabilities, which require immense and stable energy inputs. This deal positions Fervo Energy as a key player in the burgeoning market for clean energy solutions tailored to the needs of the technology sector.

This agreement follows a series of other significant achievements for Fervo Energy, including a previous agreement with Google for 12 MW of geothermal power in 2022 and a $244 million Series C funding round in 2023, which was led by the Bill Gates-backed Breakthrough Energy. The company has also secured agreements with other major corporations, indicating a broader trend of large technology firms investing in and procuring power from advanced renewable energy technologies. The enhanced geothermal sector is gaining momentum as companies seek to decarbonize their operations and secure long-term, predictable energy supplies, especially as the energy consumption of AI models continues to rise.
