Studied Hydropower Projects

[Metadata]  A database was developed in support of the conventional hydropower assessment that included more than 50 site-specific economic and environmental/social criteria. All of the data collected, along with the original source references, is also available as an electronic Excel spreadsheet that can be sorted depending on criteria. This data is cross-referenced as a GIS shapefile, which is available from the Honolulu USACE. The geospatial data allows users to geographically and visually sort projects based on any of the selected fields including island, size, scale, incremental energy cost, location, etc. The information provided allows the USACE, State, County, and private developers to analyze potential hydropower sites based on their needs and interests. This information is available as Appendix A, and provides complete site descriptions, additional caveats, and details about the original documents describing the sites. Please note that the geospatial locations of existing and proposed hydropower plants varying in accuracy. Certain sites are placed on known XY coordinate locations (e.g. existing powerplants) while others simply make reference to a certain valley or area on the island. Please review the 'Source of Geospatial Data' attribute column for more information. Please note that user-friendly aliases are available in the attribute table when opening the MXDs in this data package. These column aliases provide more information on the data entries as well as units of measurement. The user is also referred to Appendix A of the Technical Appendix which presents this database in an accessible MS Excel format.
