The U.S. hydropower fleet has been providing clean, reliable power for more than a hundred years. However, no systematic documentation existed of the U.S. fleet and the trends influencing it in recent years. The Hydropower Market Report seeks to fill this gap and provide industry and policy makers with a quantitative baseline on the distribution, capabilities, and status of hydropower in the United States. The 2026 edition focuses on updated data from 2023–2025 and contextualizes this information compared to evolving high-level trends over the past 10–20 years. It contains information on U.S. hydropower (and pumped storage hydropower) development pipeline, relicenses, license surrenders, performance metrics, and supply chain.
This report provides an update on topics included in previous editions and adds the following new content:
-Potential demand for key hydropower components (Section 6.4)
-Relicensing process durations (Section 1.4.3)
-FERC authorization process durations for new projects (Section 2.3)
-Contribution of hydropower and PSH to grid reliability (Section 5.7)
-U.S. hydropower supply chain manufacturing capabilities (Section 6.1)
