The Oak Ridge National Laboratory (ORNL) 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. Our partners include state and federal agencies, non-governmental organizations, technology and resource developers, utilities, and researchers. NHAAP is sponsored by the US Department of Energy (DOE) Office of Energy Efficiency and Renewable Energy (EERE).

Core Objectives

  • Provide an up-to-date comprehensive US hydropower geospatial database that includes information on existing hydropower facilities, infrastructure, future resources, hydrography, water availability, and environmental attributes related to hydropower development and generation;
  • Perform continual updates and expansion to the NHAAP database to ensure continuous availability of accurate, comprehensive, and up-to-date US hydropower resource statistics;
  • Provide publicly-accessible hydropower data and information services to promote hydropower market acceleration and deployment;
  • Develop tools and datasets to aid in reducing deployment barriers and environmental impacts of hydropower.
