Frequently Asked Questions

Does EIA have maps or information on the location of electric power plants and transmission lines in the United States?

The U.S. Energy Information Administration’s (EIA) interactive U.S. Energy Mapping System includes the location of power plants1 and the location of major electric power transmission lines2 in the United States. EIA currently does not publish any additional information on the location of power lines.

The street address and the latitude and longitude of power plants are in the "PlantYyy" file of the survey Form EIA-860 database.

The state, county, latitude, and longitude of power plants are in the EIA-860M data files.

EIA's Application Programming Interface (API) also contains the latitude and longitude of power plants. You must register and receive an API key to access that API series.
