Google has signed a 150MW geothermal power purchase agreement with Ormat Technologies in Nevada, reinforcing its strategy to secure firm, carbon-free electricity for growing data center demand.

The agreement was executed through NV Energy under the utility’s Clean Transition Tariff framework. The Clean Transition Tariff enables large energy users to invest in advanced generation technologies while covering the full cost of their electric service, ensuring that other ratepayers are not impacted.

Multi-Project Geothermal Portfolio

The PPA covers a portfolio of new geothermal assets that Ormat plans to develop across Nevada. Projects will be added to the portfolio as they reach commercial operations, with the first facilities expected to be energized as early as 2028 and additional capacity coming online through 2030.

The agreement will take effect once the first project begins commercial operations and will extend 15 years beyond the final project’s commissioning date. The deal remains subject to approval by the Public Utilities Commission of Nevada, with a decision anticipated in the second half of 2026.

For Ormat, the portfolio structure provides long-term revenue visibility and supports expanded exploration and drilling activities already underway in the state.

Supporting Data Center Growth

The geothermal capacity is expected to support Google’s data center operations in Nevada. As electricity demand rises alongside artificial intelligence workloads and cloud infrastructure expansion, large technology companies are increasingly seeking clean-firm power sources that provide around-the-clock reliability.

Geothermal energy offers continuous baseload generation, distinguishing it from intermittent renewables such as solar and wind. Under the Clean Transition Tariff model, Google’s investment fully covers the costs of the new capacity while contributing to grid reliability.

Expanding Google’s Geothermal Strategy

This marks Google’s second geothermal agreement executed through NV Energy’s Clean Transition Tariff. In 2024, Google signed a 100MW agreement with Fervo Energy in Nevada. The company has also entered international geothermal contracts, including a 10MW deal in Taiwan with Baseload Capital.

Ormat, one of the largest geothermal developers in the United States, continues to expand its footprint in data center-related power supply. The company recently signed a 20-year agreement with Switch and has invested in next-generation geothermal developer Sage Geosystems.

The agreement underscores how hyperscale data center operators are increasingly turning to geothermal power as part of a broader clean energy procurement strategy designed to align reliability, cost predictability and long-term decarbonization goals.
