Fervo's $11.9B Backlog: Can It Deliver the Power?

How did Fervo Energy reach $11.9 billion in contracted revenue?

Fervo reported 1,054 megawatts of capacity under binding power purchase agreements as of September 30, 2026, up from 658 megawatts and $7.2 billion in contracted revenue at the end of Q2. The increase includes a 396-megawatt, 15-year take-or-pay agreement with Google, signed in August 2026, for geothermal electricity from Cape Station in Utah.

Why does the $11.9 billion backlog matter to Fervo investors?

The contracts provide long-term revenue visibility and establish commercial demand for Fervo's geothermal power facilities, supporting investment in additional generating capacity. However, the figure represents estimated revenue over the full terms of the agreements, based on expected electricity production and contracted pricing, rather than annual revenue or cash already received.

Can Fervo deliver enough geothermal power to fulfill its contracts?

Execution remains the central challenge: Fervo reported 36 megawatts of operating capacity and 466 megawatts under construction at September 30, 2026, with another 550 megawatts ready to build. Its first 33-megawatt Cape Station GeoBlock entered commercial operation on September 30, while GeoBlock 2 began exporting test electricity on November 4 but had not yet reached commercial operation. Production shortfalls or construction delays could result in contractual damages or termination rights.

What does the Google agreement mean for Fervo's growth and stock?

The 396-megawatt agreement provides a 15-year contracted customer commitment, with first electricity deliveries expected in mid-2028 and full capacity targeted by year-end 2028. Fervo has also committed to offering Google an additional approximately 600 megawatts, potentially bringing the partnership close to one gigawatt, but that expansion is not yet a binding purchase commitment. For Fervo shareholders, successful execution could improve revenue visibility and support future growth, while construction spending, operating losses and delivery risks remain important considerations.

What should investors watch next?

The immediate milestone is commercial operation of Cape Station GeoBlocks 2 and 3, which Fervo expects by January 1, 2027, completing Phase I. Investors should subsequently monitor construction of the Google project, scheduled to begin delivering power in mid-2028, alongside capital expenditure, operating costs and actual electricity production.
