Google buys 400 MW from Fervo's enhanced geothermal plant in Utah
Original: Enhanced geothermal notches another win as Google buys 400 MW from Fervo
Why This Matters
The deal signals accelerating corporate demand for firm, 24/7 clean energy to power AI data center expansion.
Google signed a power purchase agreement to buy 396 MW of geothermal electricity from Fervo Energy's Cape Station plant in Utah, expected online in 2028. Google also holds an option to purchase an additional 600 MW through June 2030, totaling up to nearly 1 gigawatt.
Google announced on September 2, 2026 that it has signed a power purchase agreement with geothermal energy startup Fervo Energy to purchase 396 megawatts of electricity from Fervo's Cape Station facility in Utah. The plant is expected to come online in 2028 and will power a planned Google data center in the state. Google also holds an option, exercisable through June 2030, to acquire an additional 600 megawatts from the same site.
Fervo is permitted to develop up to 2 gigawatts at Cape Station, but a third-party engineering assessment cited by Fervo SVP of Strategy Sarah Jewett suggests the site could yield up to 4 gigawatts — roughly double the entire current U.S. geothermal generating capacity, according to a recent U.S. Department of Energy report.
The deal deepens a relationship between the two companies spanning over five years, during which Google has purchased some of Fervo's earliest output and participated in a pre-IPO funding round. The announcement came amid scrutiny of Google's net-zero 2030 commitment, which faced pressure after the company signed a 933 MW natural gas deal with Crusoe in Texas in April 2026. Fervo's stock rose approximately 30% on the news before partially retreating.
