Fervo Energy, Turboden Sign 1.7-GW ORC Turbine Supply Contract

Turboden America, a Mitsubishi Heavy Industries (MHI) company, signed a three-year framework agreement with Fervo Energy to supply Organic Rankine Cycle (ORC) units for up to 35 GeoBlocks totaling 1,750 MW of carbon-free, dispatchable power capacity. The multi-year arrangement will establish delivery timelines that are expected to enable faster project execution and support supply chain resilience as Fervo upscales.

Additionally, the contract may enable the optimal conversion of geothermal heat into baseload carbon-free electricity and expands the U.S.-based supply chain for Turboden’s ORC turbine design. These bolstered capabilities will help shorten lead times for current and future customers and provide geothermal energy developers with an efficient path toward meeting rising energy demand.

“Over the past two years, we have built a constructive strategic relationship with Fervo, and this framework agreement reflects a mutual commitment to continued and expanded collaboration,” said Paolo Bertuzzi, President of Turboden America and CEO of Turboden. “Geothermal energy will be essential in stabilizing a strained power grid with clean, firm energy, and Fervo has shown leadership in advancing the sector. With this announcement, we are prepared to scale delivery in the U.S. market and add MWs of new generation wherever and however they are required.”

The new contract complements Turboden’s prior agreement with Fervo to supply ORC units for three 50-MW GeoBlocks at the enhanced geothermal development in Cape Station, UT. Both companies intend to apply lessons learned across deployed units to continuously strengthen system performance. Turboden and Fervo are in the advanced commissioning stage of Cape Station’s Phase I project, with startup expected later this year. Fervo will continue to leverage Turboden’s ORC technology as a core component for future projects.

Turboden’s ORC turbines convert heat into power without increasing fuel consumption, water usage, or CO₂ emissions. Also, the units can be paired with gas turbines and a range of industrial processes that produce waste heat, unlocking additional capacity from existing infrastructure for utilities and other energy providers.

“Expanding our work with Mitsubishi Heavy Industries is a key step in scaling geothermal to meet rising U.S. power demand,” said Tim Latimer, CEO and Co-Founder of Fervo Energy. “By combining Turboden’s proven ORC technology with the global capabilities of MHI, we are strengthening the supply chain needed to build geothermal at scale. This collaboration will play a central role as we continue to develop at Cape Station and beyond and bring reliable, 24/7 carbon-free energy to the grid.”

The agreement positions Turboden America and Fervo Energy to deliver fast-tracked projects that address immediate, near-term electricity demands, especially as data center developers increasingly recognize geothermal energy as a viable baseload power solution.

Cape Station Phase II

In early October 2025, Turboden America obtained a Phase II award for Fervo Energy’s Cape Station geothermal project in Utah. Turboden will deliver equipment for three 60-MWe ORC units, totaling 180 MW of clean dispatchable power. With an additional three Gen-2 units, Turboden’s technology will generate 300 MWe of power at the Cape Station site, forming one of the largest geothermal installations globally.

Cape Station’s Phase II engineering and procurement scope includes Turboden’s turbines and control system, which are scheduled for delivery and commission by 2028. These units represent the second generation of Fervo’s modular power plant design, marking a significant milestone in the large-scale implementation of enhanced geothermal systems.
