The 2020 National Hydropower Map

Oak Ridge National Laboratory's (ORNL) HydroSource (formerly ORNL's National Hydropower Asset Assessment Program (NHAAP)) is an integrated energy, water, and ecosystem research and geospatial data integration effort for efficient, sustainable, and environmentally friendly hydroelectricity generation and water management. HydroSource is sponsored by the U.S. Department of Energy Office of Energy Efficiency and Renewable Energy (EERE) and our partners include state and federal agencies, non-governmental organizations, technology and resource developers, utilities, and researchers.

Project Overview

The overarching goal of the ORNL's HydroSource effort is to provide the Federal geospatial data standard for existing and potential hydropower resource evaluation in the United States. By offering comprehensive, detailed, reliable, and up-to-date geospatial coverage of U.S. hydropower resources, water, and environmental information, the HydroSource effort delivers information that is critical for stimulating U.S. hydropower market acceleration, deployment, technology-to-market activities, and environmental impact reduction. Through ongoing development efforts, we aim to improve and extend our geospatial data and analysis capabilities to enable more effective and efficient support for initiatives of the DOE's Water Power Program.
