Data

The Energy Zones Mapping Tool currently includes the 408 Geographic Information System (GIS) data layers listed below. Over time, data layers will be added, updated, and removed. The GIS layers are compiled from a variety of sources for the purpose of screening-level analysis, and each has a limit to the scale, currency, and accuracy of the data.

Click any column header to sort on that column. Click the sign to view a short description of the data layer. Click on the metadata link in the table below to access metadata for each layer, and to learn more about the data quality and source. We make no warranty or representation, express or implied, as to the use, accuracy, or interpretation of the data accessible at this site.

	Thumbnail	Title	Category	Data Source	Resource
		Electrical Substations	Utilities	Homeland Infrastructure Foundation Level Database (HIFLD)
		Abstract: Depicts electric power substations primarily associated with electric power transmission. In this layer, substations are considered facilities and equipment that switch, transform, or regulate electric power at voltages equal to, or greater than, 69 kilovolts. Substations with a maximum operating voltage less than 69 kilovolts may be included, depending on the availability of authoritative sources, but coverage of these features should not be considered complete. The layer includes taps, where power on a transmission line is tapped by another transmission line. Metadata File Publication Date: April 2022 - Data last updated: 2022-06-08
		Energy Potential Non-Powered Dam	Utilities	Oak Ridge National Laboratory
		Abstract: This layer was created to assess the energy potential at non-powered dams (NPDs) throughout the United States. Metadata File Publication Date: 2012 - Data last updated: 2016-11-02
		Solar Technical Potential (2020)	Utilities	National Renewable Energy Laboratory	Solar
		Abstract: Depicts estimated 2020 technical generation potential, by county, for commercial photovoltaic, concentrating solar, distributed wind, land-based wind, residential photovoltaic, and utility photovoltaic technologies. Technical generation potential is the upper bound of generation based on resource, system performance, topographic limitations, and environmental and land-use constraints, not market conditions. Estimates are modeled and have a high degree of uncertainty. See https://gds.nrel.gov/slope for more information. Metadata File Publication Date: January 2020 - Data last updated: 2021-06-07
