Geothermal firm Fervo has reached nearly $12 billion in orders, driven by projects supporting AI data center energy needs, aiming to cut costs and compete with natural gas power.

Geothermal energy company Fervo is experiencing a surge in contracted revenue, reflecting growing interest in its innovative power technology amid rising electricity demands from AI data centers. In its recent third-quarter earnings report, the firm announced nearly $11.9 billion in orders, up significantly from $7.2 billion the previous quarter, underscoring strong market confidence.

Fervo is currently on track to complete a 396-megawatt geothermal power plant for Google by the end of 2028, situated at Cape Station in Utah. Earlier this year, the company connected its first 100-megawatt geothermal plant to the grid at the same site, which experts now estimate could generate up to 8.4 gigawatts—double prior expectations of four gigawatts.

The Google project, dubbed Cape Google 400, will feature a grid-connected arrangement allowing Google to draw power as needed or sell excess energy, providing flexibility and aligning the development schedules of both parties. Fervo’s CEO Tim Latimer highlighted this phased approach as an advantage over traditional large power plants, enabling modular capacity additions to match load demands.

Fervo’s design utilizes deeper and hotter geothermal wells grouped into units called GeoBlocks, each capable of generating between 33 to 50 megawatts, tailored to power typical data center halls. This modular scalability supports incremental expansion as data centers grow.

Financially, Fervo remains in early investment stages, reporting a $43.7 million operating loss for the quarter but holding $1.9 billion in cash equivalents with manageable debt, providing solid runway for development.

Crucially, Fervo is focused on reducing construction costs. The initial Cape Station phase cost $7,000 per kilowatt, while the Google project targets $5,500 per kilowatt—equivalent, with subsidies, to natural gas fuel costs around $6 per million BTU, marking progress toward competitiveness. The company aims to reach $3,000 per kilowatt, potentially allowing geothermal to underprice natural gas even at current low fossil fuel prices.

As AI infrastructure demands intensify, Fervo's advancements in geothermal energy offer a promising low-carbon alternative to natural gas, aligning with hyperscalers’ quest for reliable and sustainable power. The company’s ongoing improvements could reshape geothermal’s role in the global energy mix, especially for energy-intensive technologies such as AI data centers.
