NHAAP Non-powered Dam Analysis Results with Potential Capacity Greater than 1MW (FY12 Update)

Description:
Abstract:
This data set is a list of U.S. Existing Non-powered Dams (NPD) with hydropower potential greater than 1MW. This data set consists of geo-referenced digital data and associated attributes created in "Hadjerioua, B., Y. Wei, S.-C. Kao and B. T. Smith (2012), An Assessment of Energy Potential at Non-powered Dams in the United States, Technical Manual 2011/251, Oak Ridge National Laboratory, Oak Ridge, TN.". The computed potential hydropower energy and capacity are estimates based on non-directly measured flow and head, and hence do not represent the actual numbers for engineering design. This resource assessment is not intended to provide economic feasibility level studies at each individual site. It will be the users' sole responsibility to determine whether if any site is worthy for further development.
Purpose:
The Department of Energy (DOE) Office of Energy Efficiency and Renewable Energy (EERE) Water Power Program has assessed the inventory of Non-Powered Dams (NPD) across the U.S. to evaluate the potential for additional hydropower generation that could contribute to the amount of renewable energy available in across the nation. Oak Ridge National Laboratory (ORNL), with input from Idaho National Laboratory (INL), executed the technical analysis within the effort. The purpose of the assessment was to quantify the generation if all NPDs with the capability for generation were developed. This information is available to developers for use in focusing their attention on selected sites for detailed analysis. However, this estimate does not consider economic limitations on facility capacity-it includes assumptions that all of the water passing a facility can be converted to electrical energy and that hydraulic head is constant at facilities. Those economic considerations will be the focus of future investigations and reporting. Site-specific designs will (a) incorporate detailed monitoring of daily and hourly head and flow variations and (b) balance initial costs with energy revenue to yield site-specific designs of lesser capacity and production potential.

The distributor shall not be held liable for improper or incorrect use of this data, based on the description of appropriate/inappropriate uses described in this metadata document. It is strongly recommended that this data is directly acquired from the distributor and not indirectly through other sources which may have changed the data in some way. The ORNL should be acknowledged as the data source in products derived from these data. The Non-power Dam Potential is public information and may be interpreted by all organizations, agencies, units of government, or others based on needs; however, they are responsible for the appropriate application of the data. The limitations of computed potential hydropower energy and capacity are described by Hadjerioua et al (2011), in which these estimates do not represent the actual numbers feasible for engineering design. It will be the users' sole responsibility to determine whether if any site is worthy for further investment.
Data_Set_Credit:
Funding and support for the Oak Ridge National Laboratory (ORNL) Non-powered Dam (NPD) Resource Assessment were provided by the Department of Energy (DOE) Office of Energy Efficiency and Renewable Energy (EERE) Water Power Program. Support from the U.S. Army Corps of Engineers (USACE), Bureau of Reclamation (Reclamation), U.S. Geological Survey (USGS), National Hydropower Association (NHA), Idaho National Laboratory (INL), and Tennessee Valley Authority (TVA) are crucial and deeply appreciated.
