Fervo Energy has signed a 15-year agreement to supply Google with 396 megawatts of geothermal power, while bringing the first unit of its Cape Station project into commercial operation. The deal gives Google a substantial long-term power commitment and ties geothermal development directly to the energy needs of AI data centres.

What happened
Fervo says the agreement is take-or-pay, meaning Google is contracted to pay for the agreed capacity. The company says the partnership creates a pathway towards nearly a gigawatt of total geothermal capacity. The power plant project is scheduled for completion by the end of 2028.
The announcement came alongside Fervo’s third-quarter results. The company reported $11.9 billion in total contracted revenue, $1.9 billion in unrestricted cash and a net loss attributable to common stockholders of $20.8 million. It also said Cape Station Phase I GeoBlock 1 has entered commercial operation.
Fervo describes its modular GeoBlock approach as a way to align construction with the expansion timelines of AI data centres. That is the company’s rationale for the build-out, not evidence that the project will meet every future demand forecast.
Why it matters
AI infrastructure needs dependable electricity as well as chips and servers. A long-term geothermal deal could give Google access to power that is not dependent on sunshine or wind at a particular moment, while giving Fervo a major contracted customer and a route to expand capacity. The scale is notable, but the schedule still matters: the project is expected to be completed by the end of 2028, not tomorrow morning.
The financial results add useful context. Fervo reports a large contracted-revenue total and substantial cash reserves, alongside a quarterly loss. That makes execution, construction and the timing of power delivery central to whether the agreement becomes a lasting supply source.
Our read
This is more than a data-centre power pledge: Fervo says its first Cape Station unit is already operating, and the Google contract sets out a long-term, quantified commitment. The next test is delivery at scale. A headline capacity number is promising; electricity arriving on schedule is the bit that keeps the servers from becoming very expensive ornaments.
What to watch
- Progress towards completing the Google project by the end of 2028.
- Whether Fervo adds capacity towards the near-gigawatt pathway it describes.
- How much power Cape Station delivers as additional GeoBlocks enter operation.
Discussion spark: Should technology companies lock in long-term geothermal power deals to support AI growth, even when the projects will take years to deliver?
