Google’s 396 MW Geothermal Deal Drives Fervo Rally as Data Center Power Demand Expands

Google expands its geothermal commitment as Fervo moves toward utility-scale deployment

Fervo Energy (FRVO) surged about 25% Tuesday after signing its largest power agreement yet with Alphabet (GOOGL)-owned Google. The 15-year power purchase agreement covers 396 megawatts of carbon-free electricity from Fervo’s Cape Station enhanced geothermal project in southwestern Utah.

The agreement comes as Google looks to secure electricity for a potential data center in Utah. Google also holds an option to purchase approximately 600 MW of additional capacity by June 2030, potentially expanding the agreement to nearly 1 gigawatt. Final plans for the data center remain subject to engineering feasibility, state and local approvals, and commercial conditions.

Key Points

• Fervo signed a 15-year agreement to supply Google with 396 MW of geothermal power from Cape Station, with deliveries targeted to begin in the third quarter of 2028.
• Google can expand its purchase by approximately 600 MW by June 2030, potentially increasing the agreement to nearly 1 GW.
• Fervo shares surged about 25% as the binding agreement provided a major commercial milestone while the company continues investing heavily to bring Cape Station online.

Google Converts Its Fervo Partnership Into a Major Power Commitment

The latest agreement significantly expands a relationship between Google and Fervo that began several years before Fervo entered the public market.

Their partnership started with Project Red, Fervo’s Nevada commercial pilot, which came online in 2023. In June 2024, Fervo, Google and NV Energy followed with a 115 MW power agreement in Nevada. The companies then expanded their relationship through a 3 GW geothermal framework agreement in March.

That framework did not require Google to purchase power. The new 396 MW PPA is different because it converts part of the broader relationship into contracted capacity.

Under the agreement, Fervo will deliver power through four successive 99 MW tranches over a 15-year delivery term, with commercial operations targeted to begin in the third quarter of 2028.

Google’s additional option could materially increase the scale of the relationship. If exercised, approximately 600 MW would be added by June 2030, bringing the total to nearly 1 GW.

Google plans to use the electricity to support a potential data center presence in Utah, although the company has not determined where that facility would be located.

Google advanced energy technologies director Lucia Tian described the geothermal project as a foundational component for a potential Utah data center even though its final location and configuration remain unresolved.

Why Did Fervo Energy Stock Surge?

The sharp move in FRVO stock followed an agreement that adds contracted capacity as Fervo transitions from demonstrating its enhanced geothermal technology toward deploying it on a much larger scale.

Fervo shares gained about 25% to $19.30 Tuesday after rising 4.1% Monday. Despite the rally, the stock had declined 58% from its May 13 trading debut through Monday’s close and fell 32% during August.

The company remains at an early stage of commercial development. Fervo reported only $113,000 of revenue in the second quarter as it had not yet begun large-scale commercial operations. At the same time, capital expenditures reached $226.5 million during the quarter.

Fervo expects another $850 million to $900 million of capital expenditures during the second half of 2026, largely connected with construction at Cape Station and other development activities. The company has committed more than $2 billion to Cape Station.

Against that spending backdrop, the Google agreement adds a large, long-term customer commitment to the project. Fervo’s total contracted capacity now stands at approximately 1,000 MW, with Shell and Southern California Edison among its other buyers.

The market reaction was also accompanied by a sharp change in retail sentiment. Stocktwits sentiment on FRVO moved from “bullish” to “extremely bullish,” while message volume increased 500%.

Cape Station Becomes the Next Test for Fervo’s Geothermal Expansion

The agreement places additional attention on Cape Station, where Fervo is using enhanced geothermal systems, or EGS, to generate electricity from heat contained in deep underground rock.

The technology applies advanced drilling and stimulation methods derived from the oil-and-gas industry to engineer underground geothermal reservoirs. The objective is to provide reliable electricity around the clock rather than power that depends on specific weather conditions.

Fervo had 500 MW under construction at Cape Station as of the second quarter. The company expects first power in late 2026, approximately 100 MW of operating capacity by early 2027 and 500 MW of cumulative operating capacity by the end of 2028.

The 396 MW Google agreement will support Cape Station’s expansion beyond its initial 100 MW phase. CEO Tim Latimer said the agreement demonstrates a repeatable commercial model for providing clean, firm power directly to large electricity users.

The project also connects Fervo’s expansion with the growing electricity requirements of data centers described in the source material. Google said the Utah project could help provide a foundation for future data center power needs, while Fervo emphasized the ability of geothermal resources to operate around the clock and be deployed where electricity is required.

Execution remains central to that expansion. The additional 600 MW available to Google is an option rather than contracted capacity, while the proposed Utah data center itself remains dependent on engineering, regulatory and commercial considerations.

What It Means for Investors

The Fervo-Google agreement brings together two parts of the current data center power story: growing electricity requirements from large technology companies and Fervo’s effort to move enhanced geothermal technology into utility-scale commercial deployment.

For Fervo, the immediate significance is contracted capacity. The company is spending heavily while generating minimal revenue as Cape Station is constructed, making the progression from pilot projects to large PPAs an important part of its commercial development.

Google’s involvement has also expanded progressively. The relationship moved from Project Red in 2023 to a 115 MW agreement in 2024, followed by a 3 GW framework and now a binding 396 MW PPA. The additional 600 MW option creates room for the relationship to grow further without making that additional capacity certain.

For Alphabet, the agreement provides another potential source of carbon-free electricity for data center infrastructure. Google has not finalized its Utah data center plans, but described the geothermal capacity as a foundational building block for a potential presence in the state.

The next operational milestones identified in the supplied information are Fervo’s expected first power from Cape Station in late 2026, roughly 100 MW of operating capacity by early 2027 and continued expansion toward 500 MW by the end of 2028.

Conclusion

Fervo Energy’s 396 MW agreement with Google marks a substantial expansion of a geothermal partnership that began with a small Nevada pilot in 2023.

The 15-year contract gives Fervo a major commercial commitment as it invests heavily in Cape Station, while Google gains access to around-the-clock carbon-free power that could support a future Utah data center. An additional 600 MW option could eventually bring the relationship to nearly 1 GW.

FRVO stock’s roughly 25% rally reflects the significance investors placed on that commercial milestone after a period of substantial weakness following the company’s May market debut. The focus now shifts from the agreement itself to Cape Station’s construction and operating milestones as Fervo works to move enhanced geothermal power toward larger-scale deployment.
