2025 US Geothermal Market Report Documents Industry Growth - CleanTechnica

The 2025 US Geothermal Market Report, published by the National Laboratory of the Rockies (NLR) and funded by the U.S. Department of Energy, highlights significant growth and technological advancements in the geothermal energy sector over the past four years. Installed geothermal power capacity in the US reached 3,969 megawatts-electric (MWe) in 2024, marking an 8% increase since 2020, compared to only about 1% growth from 2015 to 2019. Between 2021 and 2024, 26 new power purchase agreements (PPAs) were signed—more than double the number in the previous five years—totaling over 1,000 MWe of new capacity commitments. Notably, 11 of these PPAs involve next-generation geothermal systems that can be developed in areas lacking natural hydrothermal resources, and several PPAs support power supply to AI-driven data centers. The report also documents improvements in enhanced geothermal system (EG
