RiTHyMs v1.1 is a reproducible large-sample deep-learning framework for estimating daily stream temperature at unregulated river reaches across the conterminous United States (CONUS). It builds on RiTHyMs v1, which established a transferable LSTM approach using nationally available meteorological, hydrologic, and geospatial inputs to extend daily stream-temperature prediction to ungauged reaches. RiTHyMs v1.1 uses 1980 through […]

This dataset complements the fifth complete edition of the U.S. Hydropower Market Report (2026 edition) and focuses on updated data from 2023–2025 and contextualizes this information compared to evolving high-level trends over the past 10–20 years.This report updates the datasets included in previous editions and adds the following new content: -Potential demand for key hydropower […]

This presentation complements the fifth complete edition of the U.S. Hydropower Market Report (2026 edition;  Johnson and Uría-Martínez, 2026) and focuses on updated content from 2023–2025 and contextualizes this information compared to evolving high-level trends over the past 10–20 years.  It contains information on U.S. hydropower (and pumped storage hydropower) development pipeline, relicenses, license surrenders, performance […]

Existing Hydropower Asset (EHA) Annual Net Generation is a geospatial point-level dataset containing annual net generation over time (2003-2025) 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 (2003-2025) 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 […]

Existing Hydropower Asset (EHA) Annual Capacity Factor is a geospatial point-level dataset containing annual capacity factors over the years (2005-2025) 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 (2005-2025) 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.

The Existing Hydropower Assets (EHA) Plant Database provides a comprehensive nationwide inventory of U.S. hydroelectric and pumped‑storage facilities, capturing detailed technical, geographic, regulatory, and ownership attributes for thousands of plants across the U.S. The data includes plant identification, location, ownership class, FERC licensing status, hydro type (run‑of‑river, canal/conduit, peaking, pumped‑storage), unit count, installed capacity, annual […]
