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.

The Existing Hydropower Assets (EHA) Plant Database is a geospatially comprehensive point-level dataset containing locations and key characteristics of U.S. hydropower plants that are currently operational.

The U.S. Hydropower Development Pipeline database is a snapshot as of December 31, 2021 of locations and key characteristics of U.S. hydropower projects that are in the permitting/licensing/exemption phase and yet to be operational.

The U.S. Non-Powered Dam (NPD) Characteristics Inventory contains data from various sources, including identifiers, locations, and a wide variety of characteristics. These characteristics included describe US NPDs and their surroundings, including attributes related to the physical nature or design of a dam, environmental conditions, safety conditions, socioeconomic aspects, and hydropower development potential. Data may be […]

Dayflow Version 1 (V1) is a historical streamflow reanalysis dataset reconstructed for 36 years (1980-2015). The dataset provides both daily and monthly scale streamflow information at about 2.7 million NHDPlusV2 stream reaches in the conterminous US (CONUS). Dayflow is the result of a nationally scalable modeling framework that integrates the simulated runoff from the Variable […]

The ORNL Hydropower Cost Database Extract from FERC Form-1 is a cleaned and compiled version of the hydropower component of the Federal Energy Regulatory Commission’s (FERC) Electric Utility Annual Report, also known as Form-1. The database includes conventional and pumped storage hydropower plants owned by non-federal major utilities that submitted the Form 1 data from 1994-2020, representing […]

Understanding how flexibility in environmental requirements can facilitate co-optimization of hydropower production outcomes and environmental outcomes is critical for future grid decision-making and operations as renewable energy resources increase. The environmental and power system outcomes connectivity linkage maps presented here provide a framework for conceptually and quantitatively linking power system outcomes to environmental outcomes through […]

This dataset provides timeline dates, lengths, project characteristics, license characteristics, and costs of hydropower licensing and relicensing for 107 randomly selected hydropower projects that have been issued licenses since 1 October 2005 as shown in the figure above. This dataset includes information on licensing timelines including the licensing milestones shown in the bottom panel and […]
