Google plans to power its data centers with up to 150MW of geothermal energy
by
Google has signed a power purchase agreement with Ormat Technologies, a leading geothermal power developer, for up to 150MW of power to power its data centers in Nevada, USA. This partnership aims to meet the rapidly increasing demand for electricity due to the spread of AI, and to secure clean energy that can operate 24 hours a day, 365 days a year.

The power purchase agreement was signed through the Clean Transition Tariff (CTT) framework, provided by NV Energy, a Nevada public utility. The CTT is an infrastructure that enables large energy users like Google to invest in advanced power generation technologies, fully covering all costs associated with providing electric service, thereby strengthening the reliability of the local power system without burdening other electricity consumers.
Unlike other renewable energy sources that are dependent on weather, geothermal power generation can be supplied stably 24 hours a day, drawing attention as a means of resolving issues related to reliability and energy storage. Under this power purchase agreement, Ormat Technologies plans to develop a series of new geothermal projects across Nevada and establish a portfolio structure. The projects are scheduled to begin operation sequentially between 2028 and 2030, with the contract period commencing when the first project begins operation and continuing for 15 years after the final project begins commercial operation.

Doron Brashear, CEO of Ormat Technologies, emphasized that 'AI is fundamentally driving electricity demand across the technology sector, and geothermal power is uniquely positioned to provide the reliable power needed to support that growth.'
This marks Google's second geothermal PPA through NV Energy's CTT, having signed a 100MW deal with Fervo Energy in June 2024 to support a data center in Nevada. Google also has a 10MW geothermal power purchase agreement in Taiwan with Baseload Capital.
Similar trends are accelerating across the industry, with Meta signing a 150MW power purchase agreement with Sage Geosystems, a next-generation geothermal systems company, in 2024, and in June 2025, XGS Energy announced an agreement to use 150MW of next-generation geothermal power generation in New Mexico, USA.
Ormat Technologies has also strengthened its efforts to expand clean energy supplies, signing a 20-year contract in January 2026 to supply 13MW of geothermal power to data center operator Switch, as well as investing in Sage Geosystems and partnering to support the company's development of its first commercial plant.

Brianna Cobaugh, head of energy market innovation at Google, said the PPA represents a scalable model for bringing new, clean capacity to the grid while protecting other ratepayers. The PPA between Google and Ormat Technologies is subject to approval by the Public Utilities Commission of Nevada (PUCN), which is expected in the second half of 2026.
