The U.S. hydropower fleet has been an important source of flexible, low-cost, and reliable renewable energy for more than 100 years. No document existed that comprehensively summarized the current status of hydropower in the United States, so DOE commissioned Oak Ridge National Laboratory (ORNL) to write the first-ever Hydropower Market Report in 2014. The report provides industry and policy makers with a quantitative baseline on the distribution, capabilities, and status of hydropower in the United States.

Updated data from 2016 and 2017 highlights trends in the nation’s hydropower fleet and provides information on the planning and development of new hydropower projects. Data and figures on national and regional trends are also available for download on this page or on ORNL’s NHAAP website. The next Market Report is planned for release in 2018.
