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

We publish this data in our surveys, 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.

You can find this information within the "PlantYyyyy" database file of the annual survey, Form EIA-860, Annual Electric Generator Report. The county, state, latitude, and longitude of U.S. power plants are also in the monthly survey, Form EIA-860MMonthly Update to the Annual Electric Generator data files.

EIA does have data for electric power transmission lines. The data and shapefiles for electric transmission lines are available from Homeland Infrastructure Foundation-Level Data (HIFLD) geoplatform. You may contact HIFLD directly regarding its data.

EIA and HIFLD do not publish the location of electric substations. We do not publish similar maps or geographic information on the location of electric power plants or transmission lines in any other countries.
