Google signs a 15-year deal for 396 megawatts of geothermal power from Fervo’s Utah project
Fervo calls it the largest deal of its kind. Power from deep, human-made hot-rock wells is set to start flowing in mid-2028.
Google agreed to buy 396 megawatts of power for 15 years from Fervo Energy’s geothermal project in Utah, Fervo said Nov. 9 in its quarterly results. Fervo, based in Houston, calls it the largest enhanced geothermal power deal signed to date. First power is expected in mid-2028.
How enhanced geothermal works
Ordinary geothermal plants need hot rock with natural cracks and water. In an enhanced system, operators pump fluid deep underground to open cracks in hot, dry rock, let the fluid heat up as it moves through, then bring it back up to make electricity, the U.S. Energy Department explains. Fervo calls geothermal an “always-on” power source.
The deal
The contract is “take-or-pay,” meaning Google pays for the power whether or not it uses all of it. It covers eight of the project’s building blocks, which Fervo calls GeoBlocks. Fervo also promised Google an option for about 600 more megawatts, which could directly power a possible data center in Beaver County, Utah, under a state law.
With the deal, Fervo has 1,054 megawatts under binding contracts, worth about $11.9 billion in future sales, up from 658 megawatts and $7.2 billion three months earlier.
Where Fervo stands
Fervo’s first 33-megawatt unit at Cape Station began commercial operation Sept. 30. Two more are due by Jan. 1, 2027. The company had $116,000 in revenue for the quarter, an operating loss of $43.7 million and $1.9 billion in cash. It aims to cut building costs to $5,500 per kilowatt for the Google units, from about $7,000 for the first three. Google did not comment in Fervo’s release.
