Google Signed for 396 MW of Geothermal Power — The Extra 600 MW Is an Option, Not Capacity Yet

The firm power agreement is real and potentially expandable, but the future Utah data centre and additional offtake still face engineering, approval and commercial gates.

Key points

- Google Energy signed a 396 MW PPA with a Fervo subsidiary for a Utah enhanced-geothermal project. - The project is expected online in 2028. - Google has an option to expand offtake by about 600 MW, taking the total close to 1 GW by June 2030.

The numbers

| Metric | Value | Context | |---|---:|---| | Firm PPA | 396 MW | Enhanced geothermal in Utah | | Expected online | 2028 | Company schedule | | Expansion option | ~600 MW | Not committed capacity | | Potential total | ~1 GW | By June 2030 if exercised |

What happened

A Fervo Energy subsidiary entered a power-purchase agreement with Google Energy for energy products from a 396 MW enhanced-geothermal project at Cape Station in Beaver County, Utah. The company expects the project to come online in 2028. [S1, S2] The agreement also gives Google an option to expand its offtake by approximately 600 MW, potentially taking the total close to 1 GW by June 2030. The power would support a potential Google data centre in Utah. [S1, S3]

What everyone is watching

Enhanced geothermal promises around-the-clock clean electricity by applying modern drilling and reservoir techniques to hot rock. That makes it attractive to data centres that cannot rely on intermittent generation alone. The 396 MW contract is the firm centre of the story. The additional 600 MW remains an option, and final data-centre plans are subject to engineering feasibility, state and local approvals and commercial conditions. [S1]

The PriceVia angle

PriceVia analysis: power quality may be more valuable than raw megawatt volume. AI data centres need reliable supply every hour; a clean resource that behaves more like baseload power can command strategic value even when its headline capacity is smaller than a giant solar or wind portfolio. The risk is that optionality gets counted twice. Investors should not value the full near-1-GW figure as contracted capacity today. A better framework separates the signed 396 MW, the unexercised 600 MW option and the still-conditional data-centre project.

Positive scenario

Successful 2028 delivery would validate Fervo's commercial model at scale and could make the option more likely to be exercised. It could also create a repeatable template for pairing firm clean power with compute campuses.

Risk scenario

Drilling performance, construction cost, grid interconnection, approvals or a delayed data centre could shift the timeline. Enhanced geothermal can scale only if reservoir output and project economics match the contracted assumptions.

What would change the story

Watch drilling results, construction milestones, interconnection status, local approvals, the 2028 commercial-operation date and any formal exercise of the 600 MW option.
