Turboden America LLC, a subsidiary of Italy‑based Turboden SpA within the Mitsubishi Heavy Industries Group, has signed a three‑year framework agreement with Fervo Energy to supply Organic Rankine Cycle (ORC) units for up to 35 GeoBlocks. The deal could support as much as 1750 MW of carbon‑free, dispatchable power capacity across Fervo’s upcoming geothermal projects.
The agreement marks a major step in expanding domestic manufacturing of ORC systems in the United States. Under the arrangement, Turboden will deliver its proprietary turbine technology to convert geothermal heat into baseload electricity. Both companies say the framework is intended to simplify procurement, tighten delivery schedules and strengthen supply chain resilience as demand for firm, zero‑carbon power grows.
The companies had previously collaborated on Fervo’s Cape Station development in Utah, where Turboden is supplying three 50 MW ORC units. That project, currently in the final commissioning stage and due online later this year, serves as a proving ground for the scalable “GeoBlock” model Fervo plans to deploy at other US sites.
The partnership reflects a broader trend in geothermal development: pairing established turbine manufacturers with new‑generation resource developers to accelerate commercial deployment. “Geothermal can play a stabilizing role in a grid under stress from variable renewables,” said Paolo Bertuzzi, president of Turboden America and CEO of Turboden SpA, in announcing the deal.
As data centre operators increasingly seek around‑the‑clock, carbon‑free supply, both companies view the agreement as a platform for rapid growth. For Turboden, it signals a deepening presence in the US market; for Fervo, it strengthens its ability to deliver firm, geothermal power at scale.
