Datasets

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 […]

The U.S. Hydropower Development Pipeline dataset provides a comprehensive, regularly updated view of proposed and potential hydropower projects across the United States. This resource compiles information from federal agencies and other public sources to track non-powered dams considered for electrification, proposed hydropower facilities at stream reaches with no existing dams, conduit exemptions, and emerging pumped […]

This dataset compiles dam sediment management and monitoring information from surveys, case studies, and journal articles. Additionally, features described by the National Inventory of Dams (i.e., presence of sluice gates) are included to indicate known infrastructure features that may address sediment releases. The location and description of records from downstream monitoring gages are catalogued in […]

This dataset presents a suite of hydropower projections for the conterminous United States (CONUS), derived from multiple downscaled and bias-corrected Global Climate Models (GCMs) from the Coupled Model Intercomparison Project Phase 6 (CMIP6). The CMIP6 GCMs are downscaled using either statistical (DBCCA) or dynamical (RegCM) approaches, based on two meteorological reference datasets (Daymet and Livneh). […]
