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 Atlas 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 out of service (short or long term). 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 the source of the power plant layer metadata. Users can access the power plant data (as well as data on electric power transmission line border crossings) 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.

While the Energy Atlas includes map layers for electric power transmission lines and for electric substations, EIA is not the source for the data for those layers. The data and shapefiles for the electric transmission lines and substations layers are available from Homeland Infrastructure Foundation-Level Data (HIFLD) geoservice. You should contact HIFLD directly regarding their data.

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