Does EIA publish the location of electric power plants, transmission lines, and substations?

The U.S. Energy Information Administration’s (EIA) interactive U.S. Energy Altas has an electricity map application and a data catalog, which include locations and data for

  • Power plants with a combined electric generation nameplate capacity of at least 1 megawatt (MW) that are operating, on standby, or on short-term or long-term out of service. The attribute data for the power plant layer includes street address, zip code, city, county, state, latitude, and longitude for each power plant, as well as other data about the plant.
  • Electric transmission lines with voltages varying from 69 kilovolts (kV) to 765 kV (alternate current (AC) and direct current (DC) lines).
  • Electric substations that are 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 kV.

EIA is not the source for the transmission line and substations data. EIA provides the data to give users a better understanding of electric infrastructure. Users should review the metadata information to find the source of the data.

Users can access the data from the data catalog to explore and download data in shapefiles, spreadsheets, KML files, and geodatabase formats, or link to Application Programming Interface (API).

Much of the data for power plants that are included in the Energy Atlas data files are also in the "PlantYyyyy" file of the annual survey Form EIA-860 database. The county, state, latitude, and longitude of U.S. power plants are also in the monthly EIA-860M data files. EIA's Application Programming Interface (API) also contains the latitude and longitude of power plants.

EIA does not publish similar maps or geographic information on the location of electric power plants, transmission lines, or substations in any other countries.
