Datasets

The Existing Hydropower Asset (EHA) Unit database is a geospatially comprehensive point-level dataset containing locations and key characteristics of U.S. hydropower plant’s turbine units that are currently operational.

US Hydropower Retired Facilities FY2024 database is a geospatially comprehensive point-level dataset containing locations and key characteristics of US hydropower plants that are currently retired.

This dataset presents an ensemble of streamflow projections produced by the SECURE Water Act Section 9505 Assessment for the US Department of Energy (DOE) Water Power Technologies Office (WPTO). Multiple Global Climate Models (GCMs) from the Coupled Models Intercomparison Project phase 6 (CMIP6) are downscaled using either statistical (DBCCA) or dynamical (RegCM) downscaling approaches based […]

The U.S. Hydropower Development Pipeline database is a snapshot as of December 31, 2023 of locations and key characteristics of U.S. hydropower projects that are in the permitting/licensing/exemption phase and yet to be operational.

The Dayflow V2 dataset provides simulated hourly streamflow information for approximately 2.7 million NHDPlusV2 stream reaches across the conterminous US (CONUS). Multiple historic rainfall products such as Daymet, PRISM, Stage-IV, AORC, and their hybrids are used to drive a nationally scalable modeling framework based on the Variable Infiltration Capacity (VIC) hydrologic model and the Routing […]

This dataset presents a suite of high-resolution downscaled hydro-climate projections over the conterminous United States (CONUS) based on multiple selected Global Climate Models (GCMs) from the Coupled Models Intercomparison Project phase 6 (CMIP6). The CMIP6 GCMs are downscaled using either statistical (DBCCA) or dynamical (RegCM) downscaling approaches based on two meteorological reference datasets (Daymet and […]

[May 7, 2024] Note: this dataset has been expanded. Please see  https://hydrosource.ornl.gov/data/datasets/9505v3flow-1/ for further info. This dataset presents an ensemble of streamflow projections based on the hydroclimate projections dataset supporting the SECURE Water Act Section 9505 Assessment for the US Department of Energy (DOE) Water Power Technologies Office (WPTO). The six-member General Climate Model (GCM) ensemble […]

Relicensing is an important milestone in the lifecycle of U.S. FERC-licensed hydropower and pumped storage hydropower (PSH) plants. The terms and conditions of a new license may involve substantial capital investment and changes in mode of operation. Additionally, some licensees decide not to pursue relicensing and instead apply for a license surrender.  The U.S. Hydropower Relicensing […]

U.S. Hydropower Relicensing and License Surrender Data and Metadata is a snapshot (as of December 31, 2022) of locations and key characteristics of U.S. hydropower projects that are in the relicensing or license surrender process.
