Existing Hydropower Asset (EHA) Annual Capacity Factor is a geospatial point-level dataset containing annual capacity factors over the years (2005-2025) and key characteristics of operational U.S. hydropower plants with 1 megawatt or greater of nameplate capacity. EIA form 860 and EHA are the primary sources of the derived data. Pumped storage and hybrid plants are […]

Existing Hydropower Asset (EHA) Annual Capacity is a geospatial point-level dataset containing annual capacity over the years (2005-2025) and key characteristics of operational U.S. hydropower plants with 1 megawatt or greater of nameplate capacity. EIA form 860 and EHA are the primary sources of the derived data.

The Existing Hydropower Assets (EHA) Plant Database provides a comprehensive nationwide inventory of U.S. hydroelectric and pumped‑storage facilities, capturing detailed technical, geographic, regulatory, and ownership attributes for thousands of plants across the U.S. The data includes plant identification, location, ownership class, FERC licensing status, hydro type (run‑of‑river, canal/conduit, peaking, pumped‑storage), unit count, installed capacity, annual […]

The Existing Hydropower Assets (EHA) Unit Database provides a detailed, unit‑level inventory of hydroelectric and pumped‑storage generating units across the United States. The data includes plant and unit identifiers, geographic coordinates, ownership, turbine type, manufacturer, commissioning and refurbishment years, installed capacity, hydraulic head, and other operational characteristics. The dataset covers a wide range of technologies […]

The U.S. Hydropower Retired Facilities Data, 2026 dataset documents hydropower and pumped‑storage facilities across the United States that have been fully retired from operation, spanning retirements from the 1960s through 2025. Records include detailed information such as plant identifiers, retirement year, geographic location, ownership, dam ownership, hydro type, FERC licensing or exemption status, operational mode (run‑of‑river, […]

This dataset provides comprehensive hydrological information about reservoir sedimentation in Texas, including observed and remotely sensed sediment concentration, river discharge, watershed boundary, lake geometry, reservoir capacity, land use and land cover (LULC), and population data. In-depth interpretation of the dataset is elaborated in a journal article, entitled “Sedimentation hotspots and nonlinear trapping in Texas reservoirs […]

The Cost Model for Pumped Storage Hydropower Geomembrane Lining Systems offers an approximation of geomembrane lining system costs for pumped storage hydropower (PSH) reservoirs. Geomembrane lining systems have been used around the world for over 60 years for the construction of dams and reservoirs. Although geomembrane lining systems have found widespread use in the construction […]

The U.S. Hydropower Relicensing and License Surrender Database (2026) provides a comprehensive, nationwide snapshot (as of December 31, 2025) of hydropower projects across the United States that are undergoing Federal Energy Regulatory Commission (FERC) relicensing or license surrender processes. Compiled by Oak Ridge National Laboratory, the dataset includes detailed project-level attributes such as geographic location, ownership type, […]

HILARRI is a database of links between major datasets of operational hydropower dams and powerplants, and inland water bodies. These connections are critical for conducting large-scale analysis of hydropower infrastructure and their associated natural and engineered water systems. Features include: These hydropower infrastructure features are linked to several major datasets that provide hydrologic and hydraulic […]
