Fervo Energy’s Cape Station has started sending electricity to the grid in Utah, marking what the company calls the first utility-scale greenfield enhanced geothermal system to reach First Power.
According to the company, the first 33-megawatt GeoBlock at Cape Station synchronized with the grid on September 24. It is the opening unit of an approximately 100 MW first phase, with the other two GeoBlocks expected to reach contractual commercial operation by January 1, 2027.
From drilling technology to grid power
Enhanced geothermal systems use engineered underground reservoirs rather than relying only on naturally occurring hydrothermal resources. Fervo applies horizontal drilling techniques adapted from oil and gas development to access hot rock, circulate fluid through the subsurface and bring heat back to the surface for electricity generation.
The scale-up follows Fervo’s Project Red in Nevada, which has supplied electricity to the grid since 2023. Google previously described that project as a way to provide round-the-clock carbon-free electricity on the grid serving its Nevada data centers. Now the same basic technology is moving into a much larger commercial buildout.
AI demand is pulling firm power toward data centers
Cape Station’s timing intersects with a much larger infrastructure problem: AI data centers need enormous amounts of continuous electricity. BitcoinVersus.Tech recently reported on Applied Digital’s $3.2 billion Alabama AI data center, while another hardware story examined 800 VDC protection for AI power systems. Generating the electricity and delivering it efficiently are becoming parts of the same engineering challenge.
Google signed a 396 MW power purchase agreement with Fervo earlier this month for future output from the Cape Station GeoCluster. The deal is designed to support a potential Utah data center and gives Google an option to expand its offtake by roughly another 600 MW, bringing the possible total close to one gigawatt.

900 MW contracted, another 400 MW under construction
Fervo says approximately 900 MW of Cape Station output is already under contract. Beyond the first roughly 100 MW phase, another 400 MW is under construction with expected commercial operation in 2028. At full contracted output, the company estimates the development could generate electricity equivalent to the annual consumption of nearly one million U.S. homes.
The project adds another option to a power market where developers are experimenting with many energy sources. BitcoinVersus.Tech recently covered a German site combining solar, hydro and Bitcoin mining, an example of how compute loads can increasingly follow specialized energy resources.
The milestone does not mean Cape Station is finished. The first GeoBlock is still ramping while additional wells and generating units are commissioned. But First Power changes the project from a drilling and construction story into an operating power-generation story, with its first electricity now flowing to the grid.
