Datasets

This dataset contains geo-referenced information on fish passage facility existence, type, and direction at hydropower developments across the conterminous United States (CONUS) presented in the ORNL Hydropower Fish Passage Webmap. It was developed through collaborative partnerships with fish passage engineers and biologists at both the US Fish and Wildlife Service (USFWS) and the National Marine […]

The U.S. Hydropower Development Pipeline database is a snapshot as of December 31, 2024 of locations and key characteristics of U.S. hydropower projects that are in the permitting/licensing/exemption phase and yet to be operational. The dataset has been updated on July 2nd, 2025 to add Seminoe PSH and Scott’s Dam HY projects for pending licenses; […]

This dataset has a new version at https://hydrosource.ornl.gov/data/datasets/rectifhydplus_v1-1/ The files included in this page are as follows: RectifHydPlus.zip: contains the main RectifHydPlus dataset, containing monthly generating totals for 590 plants (> 10MW) over the forty-year period 1980 – 2019. Three versions are offered: 1. Estimated historical monthly generation, backfilled with EIA observed monthly generation where […]

In the last decade, retrofits of existing nonpowered dams (NPDs) have made up the largest share of capacity increases for US hydropower. Accurate estimates of potential capacity and generation at NPDs help identify sites that may be worth investing in detailed feasibility analyses and design exploration. This dataset contains estimates of technical potential capacity and […]

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 […]

Existing Hydropower Asset (EHA) Annual Capacity is a geospatial point-level dataset containing annual capacity over the years (2005-2023) 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.

Existing Hydropower Asset (EHA) Annual Capacity Factor is a geospatial point-level dataset containing annual capacity factors over the years (2005-2023) 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 Gross Generation is a geospatial point-level dataset containing annual gross generation over time (2003-2023) 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. Hydropower units are excluded. Existing Hydropower […]
