HydroSource provides U.S. hydropower market information and data through several efforts, including the Hydropower Market and Trends Reports (HMR), Existing Hydropower Assets (EHA), and U.S. Hydropower Generation Over Time. These efforts provide information about the existing U.S. hydropower fleet along with information about hydropower in the U.S. and globally.  

The Hydropower Market and Trends Reports (HMR) characterize trends in U.S. hydropower development (for new projects and upgrades/refurbishments of existing facilities), performance, and the supply chain, with metrics that help evaluate progress towards strategic goals of growth, performance, and reliability of the U.S. hydropower fleet. The HMRs also improve the understanding of what is different about hydropower vs. other electricity-generation technologies by highlighting values that are often overlooked (e.g., hydropower facilities provide additional services to the electrical grid beyond power generation, and hydropower facilities are connected to reservoirs that serve multiple purposes and benefits).

The Existing Hydropower Assets (EHA) assimilates up-to-date U.S. hydropower fleet information from multiple existing energy, water, and infrastructure datasets. HydroSource Baseline Data sources include the Energy Information Administration (EIA), Federal Energy Regulatory Commission (FERC), U.S. Army Corps of Engineers (USACE), U.S. Bureau of Reclamation (Reclamation), Tennessee Valley Authority (TVA), and U.S. Geological Survey (USGS). The integrated datasets have supported multiple U.S. initiatives related to market acceleration, environmental impact reduction, technology-to-market activities, and climate change impact assessments.

Additional historic data is accessible through U.S. Hydropower Generation Over Time. Using Energy Information Administration (EIA) data, HydroSource has generated visual representations of annual and monthly U.S. hydropower generation that can be viewed from state or single plant scales.
