Fervo Energy signs a 396 MW enhanced geothermal power deal with Google for a Utah data centre

Fervo Energy announced on 1 September 2026 that it has signed a 396 megawatt power purchase agreement with Google, which the company calls the world’s largest enhanced geothermal PPA to date. The power will come from Fervo’s Cape Station project in Beaver County, Utah, and is intended to serve as what the two companies describe as a foundational building block for a potential Google data centre in the state. The deal includes an option for Google to add roughly 600 MW more, taking total contracted enhanced geothermal capacity to nearly 1 gigawatt by June 2030.

Fervo’s Form 8-K filed with the US Securities and Exchange Commission shows the contract was signed on 26 August 2026 between Cape Generating Station 6 LLC, a Fervo subsidiary, and Google Energy LLC, an Alphabet subsidiary, with parent guarantees from both Fervo and Alphabet. The delivery term is 15 years. Capacity arrives in four successive tranches of 99 MW each, with target commercial operation dates beginning in the third quarter of 2028. Neither company disclosed the price.

What the enhanced geothermal contract covers

Enhanced geothermal systems drill into hot rock that lacks natural water flow, then fracture it and circulate fluid between horizontal wells to bring heat to the surface. Unlike wind and solar, the output runs around the clock. Fervo’s chief executive and co-founder Tim Latimer stated that “this agreement reinforces that EGS is ready to power the next generation of computing infrastructure.” Michael Terrell, head of advanced energy at Google, stated that “the next chapter of advanced power generation technology is being written in Utah.”

The 8-K adds detail the press release leaves out. The expansion option obliges Fervo to offer Google approximately 600 MW more so that total contracted capacity would be not less than about 950 MW, with a guaranteed commercial operation date no later than June 2030. Google may accept or decline, and any expansion needs a separate definitive agreement. If Fervo fails to make the offer it must reimburse Google for amounts already paid for deemed delivered energy.

Delivery relies on what the filing calls flexible power delivery pathways under Utah Senate Bill 132, subject to regulatory approval. Under that route the geothermal plant, supplemented by other energy resources, would supply a closed private generation system configured for either front-of-the-meter or behind-the-meter interconnection to serve data centre load, with a target commercial operation date in the first half of 2030. Fervo states the arrangement adds around-the-clock capacity at no cost to existing ratepayers. No utility off-taker is named in either document, and Google has not said where in Utah the data centre would be built; the final decision depends on engineering feasibility, state and local approvals and commercial conditions.

How the deal changes Fervo’s order book

Before this contract, Fervo’s disclosed offtake from Cape Station consisted of two 15-year PPAs with Southern California Edison totalling 320 MW, announced on 25 June 2024, and a 31 MW, 15-year PPA with Shell Energy North America announced on 15 April 2025, at which point the company said the 500 MW at Cape Station was fully contracted. Separately, Fervo signed a 115 MW PPA in June 2024 with NV Energy on Google’s behalf under Nevada’s Clean Transition Tariff. Adding the new 396 MW to those disclosed agreements gives roughly 1 GW of contracted capacity, a sum of the published figures rather than a company-stated total.

Analysts at William Blair wrote in a note on 1 September that the PPA “increases contracted revenue across Fervo’s portfolio by about 65%”, according to Utility Dive. That ratio is consistent with the disclosed capacity figures: 396 MW is 64 per cent of the roughly 615 MW contracted before the deal. The same note said the deal “strengthens our belief that Fervo’s enhanced geothermal systems provide a critical solution” to what the bank calls a baseload imperative for AI data centres, and listed first-of-a-kind execution at Cape Station’s first phase, interconnection bottlenecks, capital intensity and competing technologies as the main risks.

The market reaction was strong but reports of its size differ. Canary Media reported the shares up 15 per cent on the morning of 1 September; TechCrunch reported a rise of about 30 per cent on the day before profit-taking on 2 September. William Blair noted that on 2 September the stock still stood 49 per cent below the highs reached after its May initial public offering.

Cape Station and the timeline to 2028

Cape Station is near Milford in south-west Utah. Its first phase, about 100 MW built as three 33 MW units Fervo calls GeoBlocks, is targeted to deliver first power from its first GeoBlock in the fourth quarter of 2026, with the other two following in early 2027. A second phase of 400 MW across eight 50 MW GeoBlocks is scheduled for 2028. The Google contract sits in a further expansion, which Fervo calls the Cape Station EGS GeoCluster. Fervo’s second-quarter 2026 results put the all-in cost of the first phase at $7,000 per kilowatt, with a target of $5,500 per kW for the second phase and a long-term goal of $3,000 per kW, and raised the company’s development target to 1.1 GW by 2030. Canary Media reports the company is investing over $2 billion in the site, which is permitted for up to 2 GW.

Geothermal supplies about 0.4 per cent of US electricity today, according to Canary Media. Fervo’s Project Red in Nevada, a 3.5 MW pilot that has supplied the local grid including Google’s Nevada data centres since 2023, remains the largest operating enhanced geothermal plant in the country, though a rival pilot recently came online in Texas, covered in Sage Geosystems brings 3MW geothermal plant online. A different approach to reaching hotter rock is described in Quaise raises $134M for superhot geothermal energy, and the drilling techniques Fervo borrowed from the shale industry are explained in The Future of Geothermal Drilling: What’s Next?.

Why hyperscalers are buying geothermal

The contract is part of a wider pattern of technology companies signing firm, carbon-free power for data centres. Data Center Dynamics lists Meta’s 150 MW agreement with Sage Geosystems in 2025 and a further 150 MW with XGS Energy in New Mexico in June 2026, and Microsoft’s 51 MW ten-year contract with Contact Energy in New Zealand from 2023. Google’s own portfolio ranges from the record solar site covered in Google, Cypress Creek break ground on largest US solar site to a 933 MW natural gas deal with Crusoe in Texas in April 2026, which TechCrunch cites as the tension in the company’s net-zero-by-2030 goal. The demand behind these purchases is quantified in UN report quantifies AI’s carbon, water, land footprint, and the funding flowing into the sector in Climate tech VC funding hits $26.1bn in H1 2026.

A Jefferies note from 14 August 2026, cited by Utility Dive, described Fervo as in a heavy investment phase and flagged temporary transmission-related curtailment issues for 2027 raised on the company’s second-quarter call. Canary Media also reports a standing arrangement giving Google a right of first refusal on up to 3 GW from certain new Fervo plants; that detail appears only in Canary Media’s reporting.

About Fervo Energy

Fervo Energy was founded in 2017 in Houston, Texas, by Tim Latimer, its chief executive, and Jack Norbeck, its chief technology officer. The company applies horizontal drilling and hydraulic stimulation techniques from the oil and gas industry to geothermal, pairing horizontal wells to circulate water through hot rock. It signed its first corporate agreement with Google in 2021 and brought its Project Red pilot in Nevada online in 2023.

From 2024 the company moved to utility scale at Cape Station in Utah, contracting 320 MW to Southern California Edison in June 2024, 115 MW through NV Energy for Google the same month and 31 MW to Shell in April 2025, when it expanded the project to 500 MW. It closed a $462 million Series E in December 2025 and a $421 million debt package in March 2026, then listed on Nasdaq on 13 May 2026 under the ticker FRVO after pricing 70 million shares at $27. The 396 MW Google contract announced on 1 September 2026 is its largest single agreement, and the company says it will route the power through Utah’s SB 132 private generation framework.
