Fervo Energy’s 396 MW Google PPA Raises the Stakes
Estimated reading time: 5 minutes · Last updated:
Fervo Energy has signed a 396-MW power purchase agreement (PPA) with Google to supply geothermal power from its Cape Station development in Utah, a deal first reported by The Motley Fool. The agreement, which Google can expand by an additional 600 MW, moves Fervo's contracted sales to about 1.1 GW and ties the company to multi-year offtake visibility that the developer says will support growth into a roughly 1 GW portfolio by June 2030. Management aims to deliver around 100 MW in Phase I with commercial operations later in 2026 or in early 2027, and to scale via eight 50 MW GeoBlock modules in Phase II toward deliverability in 2028.
Key takeaways
- Google signed a 396-MW PPA with Fervo Energy for power from the Cape Station geothermal project in Utah.
- Google holds an option to expand offtake by 600 MW, taking total potential capacity to roughly 1 GW by June 2030.
- Fervo's total contracted power sales are about 1.1 GW after the deal, and the company previously committed to developing 3 GW of geothermal projects.
- Fervo raised about $2.2 billion in its public debut and plans to allocate between $850 million and $900 million to capital spending during the coming twelve months.
- Phase I aims for about 100 MW of output with commercial operations later in 2026 or early 2027; Phase II plans another 400 MW and commercial operations projected to begin in 2028.

How big is the Google deal and what it commits
The headline item is a 396-MW PPA between Google and Fervo Energy for output from Cape Station in Utah. Under the contract Google will offtake that capacity and holds a separate agreement to expand its offtake by 600 MW, which Fervo says would bring the total potential capacity tied to Google to roughly 1 GW by June 2030.
That 396-MW agreement follows an earlier 115-MW PPA Fervo signed in June 2024 with Google and NV Energy and sits on top of the company’s prior commercial pilot work dating back to Project Red in 2021. Fervo reports this deal raises its total contracted power sales to about 1.1 GW and validates the scale assumptions management has used for revenue visibility.
The technology behind the promise: EGS and modular GeoBlocks
Fervo builds on Enhanced Geothermal Systems, or EGS, which uses horizontal drilling and stimulation to access hot rock beyond naturally occurring hydrothermal sites. That allows developers to place geothermal plants in a broader range of geology than traditional resource-dependent projects.
To translate that approach into repeatable plants, Fervo plans to use its GeoBlock architecture: eight self-contained 50 MW generation blocks that can be engineered once and mass-produced. By breaking large builds into 50 MW modules, the company expects to shorten build cycles and reduce unit costs compared with bespoke geothermal fields.
The financial picture: cash on hand, capex and near-term burn
Fervo completed its public listing on May 12 and raised about $2.2 billion in the process, funds the company says will back its near-term buildout without leaning on high-yield debt. Management projects capital expenditures of $850 million to $900 million over the next 12 months and also says it expects net losses as it scales operations.
The Google PPA and the firm’s existing contracted portfolio give Fervo visibility into future contracted revenue, but the company will continue to burn cash while it moves from pilot to commercial scale. Delivering Phase I on schedule and hitting early performance metrics will be the clearest near-term financial inflection point for the business.
Timing, milestones and what must go right
Fervo’s near-term plan is divided into phases. Phase I targets roughly 100 MW of capacity and is expected to enter commercial operation in late 2026 or early 2027; Phase II, which will deploy multiple GeoBlock units, is projected to add about 400 MW and to begin commercial activity in 2028.
Execution hinges on drilling schedules, permitting in Utah for Cape Station, serialised manufacturing of 50 MW blocks, and completing grid interconnection work on time. Each of those steps carries a practical delivery risk that will determine whether the Google offtake converts from contract into steady contracted cashflow as planned.
| Item | Figure | Source / timing |
|---|---|---|
| Google PPA (new) | 396 MW | Cape Station; deliver by 2028 |
| Google expansion option | 600 MW | Potential total ~1 GW by June 2030 |
| Total contracted sales (post-deal) | about 1.1 GW | Fervo reported |
| Phase I target | around 100 MW | commercial operations later in 2026 or early 2027 |
| Phase II target | about 400 MW | commercial operations projected to begin in 2028 |
Case for and against successful scaling
The case for
- The Google PPA supplies a large, long-duration offtake that aligns with AI data-center demand for 24/7 baseload power and gives Fervo multi-year contracted demand.
- GeoBlock modularisation could cut unit engineering and construction costs if Fervo executes serial production of 50 MW blocks and repeats the design across projects.
The case against
- Large near-term capital needs — management projects $850 million to $900 million in capex over the next 12 months — increase execution and financing risk while the company posts net losses.
- Drilling, permitting and interconnection delays in Utah or elsewhere could push commercial starts beyond the 2027–2028 window and defer contracted revenue.
What to be careful about
- Schedule and execution risk on Phase I and Phase II that could delay revenue from the Google PPA.
- High near-term capital expenditure ($850–900 million projected) and sustained net losses while scaling.
- Resource and subsurface risk inherent to geothermal drilling despite EGS techniques.
- Permitting, supply-chain and grid interconnection delays in Utah for Cape Station.
The bottom line
The Google 396-MW PPA represents a major commercial validation of Fervo’s EGS approach and moves the company from pilot-stage proofs toward a modular, repeatable production model. The deal raises contracted sales to about 1.1 GW and sits alongside Fervo’s $2.2 billion capital raise and an $850–900 million near-term capex plan; those dollars are intended to fund Phase I and Phase II builds. Execution risk — drilling, permits, supply chains and grid work — remains the central obstacle between contract and cashflow. For investors and buyers of clean baseload power, the coming milestones in early 2027 and 2028 will separate promise from deliverable capacity.
What to watch
- Watch for Fervo's Phase I commercial start, which management projects in early 2027.
- Watch for commercial operations for Phase II, which Fervo projects will begin in 2028.
- Watch for whether Google exercises its 600 MW expansion option, which would take the agreement's potential to roughly 1 GW by June 2030.
Frequently asked questions
What is Enhanced Geothermal Systems (EGS)?
Enhanced Geothermal Systems use horizontal drilling and stimulation to access hot rock where natural hydrothermal resources aren't present; Fervo uses EGS to site projects beyond traditional geothermal zones and to generate baseload power suitable for data centers.
When will Fervo start delivering power under the Google deal?
Management aims to deliver about 100 MW in Phase I with commercial operations later in 2026 or early 2027, and to expand with Phase II—about 400 MW—whose commercial operations are projected to begin in 2028.
How material is the Google PPA to Fervo's business?
The 396-MW PPA increases Fervo’s contracted power sales to about 1.1 GW and, together with a potential 600 MW Google expansion, underpins the company’s plan to reach roughly 1 GW of Google-linked capacity by June 2030, improving revenue visibility as the company scales.
