Ormat Technologies announced a long-term portfolio Power Purchase Agreement (PPA) to supply up to 150 megawatts (MW) of new geothermal energy to support Google’s expanding data center operations in Nevada. Executed in coordination with state utility NV Energy, the deal leverages Nevada’s Clean Transition Tariff (CTT) framework, a regulatory structure designed to let large energy consumers fund advanced clean power projects while fully covering associated electric service costs to protect everyday ratepayers. Under the arrangement, Ormat will construct and integrate a series of new geothermal facilities across Nevada, scheduled to come online incrementally between 2028 and 2030.
The contract takes effect when the first facility begins commercial operations and extends for 15 years beyond the completion of the final project, ensuring long-term revenue stability for Ormat and a predictable source of around-the-clock, clean-firm power to support Google’s AI and cloud infrastructure workloads. Pending final approval by the Public Utilities Commission of Nevada (PUCN), the agreement doubles down on Google’s 24/7 carbon-free energy goals while establishing a scalable, repeatable commercial template for utility-scale clean tech deployment.
Google Inks Another Similar Agreement
Similarly, Google has inked another similar agreement in Utah. Both agreements represent core components of Google’s strategy to secure 24/7 carbon-free, firm baseload power for its data centers by combining proven energy generation with innovative commercial execution. While Ormat Technologies supplies up to 150 MW of clean electricity utilizing conventional hydrothermal and geothermal resources across Nevada, Fervo Energy delivers next-generation, Enhanced Geothermal Systems (EGS) capacity, scaling from its initial 115 MW Nevada project to a massive 396 MW expansion at Utah’s Cape Station. Crucially, both deals leverage novel regulatory frameworks to insulate local ratepayers from development costs while ensuring direct-to-load or grid-integrated delivery: the Ormat deal builds on the Clean Transition Tariff (CTT) pioneered alongside NV Energy in Nevada, whereas the Fervo deal utilizes Utah’s SB132 legislation to enable flexible direct-contracting pathways. Together, these complementary contracts demonstrate Google’s multi-pronged approach to scaling geothermal energy, balancing Ormat’s established, low-risk infrastructure with Fervo’s frontier EGS technology to meet the immense power demands of expanding AI and cloud workloads.

Google has signed a 150MW geothermal Power Purchase Agreement (PPA) with geothermal developer, Ormat Technologies in Nevada. The deal, signed between Ormat and Nevada public utility NV Energy, is expected to support Google’s data center operations in the state. It was signed as part of NV Energy’s Clean Transition Tariff (CTT). Moreover, the PPA covers a multi-project portfolio of geothermal assets. The CTT is a pathway created by NV Energy that allows utilities and large energy users like Google to invest in advanced generation technologies.
Furthermore, they can do this while fully covering all costs associated with their electric service. “The momentum of the Clean Transition Tariff through this agreement with NV Energy, Google, and Ormat demonstrates a proven, scalable model for large customers to partner with utilities and technology providers to bring new clean capacity to the grid,” said Briana Kobor, head of Energy Market Innovation, Google. Over the past few years, Google has put efforts in renewable energy to support its data center advancements. One of the most recent and significant ones is the 1GW solar power agreement with TotalEnergies.
Scope on the Google-Ormat 150MW Geothermal PPA
The Google-Ormat geothermal PPA is subject to approval by the Public Utilities Commission of Nevada (PUCN), which is expected in the second half of 2026. Once approved, the PPA will enable the establishment of a portfolio structure. Afterwards, it will Google to develop a series of new geothermal projects across the Nevada market, according to Ormat. The projects will be added to the generation portfolio upon reaching commercial operations, with the first projects expected to be energized as early as 2028 and continuing through 2030.
The PPA will come into force when the first project within the portfolio reaches commercial operations. Moreover, it will extend 15 years beyond the final project’s commercial operation date. “By adding up to 150MW of new clean-firm geothermal capacity in Nevada, we are utilizing a repeatable framework that fully covers all costs associated with our electric service, ensuring the CTT insulates other ratepayers while strengthening the reliability of the local power system,” Briana noted. Google seems to be making an innovative approach through using geothermal PPAs to secure energy.
In June 2024, the hyperscaler signed an agreement with Fervo Energy to support the development of 100MW of geothermal power in Nevada. Ormat Technologies is one of the largest geothermal developers in the US. Last month, it signed a 20-year PPA with data center operator Switch to supply the company with 13MW of power. The company has also lent its backing to enhanced geothermal systems company Sage Geosystems.
