Datasets

[March 6, 2024] Note: this dataset has been expanded. Please see https://hydrosource.ornl.gov/dataset/9505V3_1 for further info. This dataset presents a suite of high-resolution downscaled hydro-climate projections over the conterminous United States (CONUS) based on a six-member General Climate Model (GCM) ensemble from the state-of-the-art Coupled Models Intercomparison Project phase 6 (CMIP6). The CMIP6 GCMs are downscaled using statistical […]

Environmental flow requirements included in Federal Energy Regulatory Commission (FERC) hydropower licenses are important for balancing natural properties and benefits of river ecosystems (e.g., healthy species, recreation, water supply, flood control) supporting hydropower production. In some cases, environmental flow requirements may limit operational flexibility given current operational schemes and make a hydropower plant less able […]

Existing Hydropower Asset (EHA) Annual Net Generation is a geospatial point-level dataset containing annual net generation over time (2003-2021) and key characteristics of operational U.S. hydropower plants with 1 megawatt or greater of nameplate capacity. EIA 923 and EHA are the primary sources of the derived data. Pumped storage and hybrid plants are excluded. Existing […]

Existing Hydropower Asset (EHA) Annual Gross Generation is a geospatial point-level dataset containing annual gross generation over time (2003-2021) and key characteristics of operational U.S. pumped storage and hybrid plants with 1 megawatt or greater of nameplate capacity. EIA 923 and EHA are the primary sources of the derived data. Conventional hydropower plants are excluded. […]

Existing Hydropower Asset (EHA) Annual Capacity Factor is a geospatial point-level dataset containing annual capacity factors over the years (2005-2021) 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 (2005-2021) 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.

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 […]

US Hydropower Retired Facilities FY2022 database is a geospatially comprehensive point-level dataset containing locations and key characteristics of US hydropower plants that are currently retired.

RectifHyd provides estimated monthly hydroelectric power generation for approximately 1,500 power plants in conterminous United States for the period 2001 through 2020. Monthly generation estimates are created by disaggregating each plant’s annual generation with the aid of reservoir operations and downstream streamflow data. RectifHyd provides an alternative to EIA-923 imputed monthly generation for U.S. hydropower plants.
