Fervo Starts 33-MW Utah Geothermal Unit, Plans 400-MW Expansion

Fervo Energy has brought the first generating unit at its Cape Station enhanced geothermal project in Beaver County, Utah, into commercial operation. The 33-megawatt GeoBlock synchronized to the grid on September 24 and declared commercial operation on September 30, 2026, one day before its contractual commercial operation date. Fervo says the unit met the production threshold under its agreement and is now generating revenue under a power purchase agreement. The company describes the milestone as the first time a greenfield enhanced geothermal development has reached commercial operation. CEO and co-founder Tim Latimer called it “both a huge milestone for Fervo, and a turning point for the entire energy industry.”

The achievement is relevant to government energy planners and contractors because it provides a commercial operating example for enhanced geothermal systems, a potential source of firm, carbon-free electricity. Cape Station’s Phase I is planned to total approximately 100 MW across three 33-MW GeoBlocks. Commissioning of the remaining two Phase I units is expected to continue through January 1, 2027, their contractual commercial operation deadline. Fervo says it built and commissioned the first facility in 23 months and believes it can reduce the timeline to 18 months for future GeoBlocks. Dawn Owens, Fervo’s senior vice president and head of development and commercial markets, said each unit should make the next “faster and more predictable,” with repeatability central to scaling and reducing costs.

Fervo plans a 400-MW Phase II expansion comprising eight 50-MW GeoBlocks, scheduled to reach commercial operation in 2028. The project’s ability to scale economically will matter to prospective suppliers, construction firms, drilling and well-service providers, equipment vendors, and power buyers assessing future work or supply options. Industry-reported project figures put estimated installed costs at about $7,000 per kilowatt for Phase I and $5,500 per kilowatt for Phase II, against Fervo’s long-term target of $3,000 per kilowatt. The company attributes the lower Phase II estimate in part to its newer 3.0 well design. Those figures indicate a cost-down objective rather than a guarantee, and continued execution will be important to the project’s commercial case.

The power sales demonstrate private-sector interest but do not establish a federal or state procurement opportunity. Shell Energy is identified as the buyer for the first GeoBlock’s output; the price and other terms of that agreement have not been disclosed. Separately, Google agreed to purchase 396 MW from Cape Station, with an option to expand purchases to nearly 1 GW. That commitment supports development of the project’s broader enhanced geothermal system and reflects demand for round-the-clock carbon-free electricity, including from AI data centers. For government buyers considering geothermal in power-supply strategies, the project offers a commercial reference point, while grid-interconnection delays, financing constraints, and questions about performance beyond early operating sites remain relevant risks. No solicitation, award, open bid, or specific public-sector procurement schedule is identified in the reporting.

• Fervo Energy’s first Cape Station GeoBlock delivers 33 MW of net power and entered commercial operation one day before its contractual date.
• The unit synchronized to the grid on September 24 and declared commercial operation on September 30, 2026; revenue is being generated under a power purchase agreement.
• Shell Energy buys the first GeoBlock’s power; the agreement’s price and other terms were not disclosed.
• Phase I totals approximately 100 MW across three 33-MW GeoBlocks, with the remaining two units expected to reach contractual commercial operation by January 1, 2027.
• Phase II is planned as a 400-MW expansion with eight 50-MW GeoBlocks, scheduled for commercial operation in 2028.
• Google has agreed to buy 396 MW from Cape Station and holds an option to expand purchases to nearly 1 GW; this is a private-sector agreement, not a government procurement.
• Reported estimated installed costs are about $7,000/kW for Phase I and $5,500/kW for Phase II; Fervo’s long-term target is $3,000/kW.
• Fervo reports a 23-month build and commissioning timeline for the first unit and says it is confident of reaching an 18-month timeline for future GeoBlocks.
• Potential suppliers and contractors can monitor commissioning and Phase II development, but the reporting identifies no open bid opportunity or procurement timeline.
• Government power buyers should weigh geothermal’s potential for firm, carbon-free supply against grid-interconnection, financing, and operating-performance risks.
