I'm looking for shapefiles or other spatial definitions for electric utility service areas in the United States. Does this exist in a single place anywhere?
The US Energy Information Administration has a few geographic resources (like the US Energy Mapping System and the State Energy Data System but there's no sign of a collection of electric utility service areas.
On a state-by-state basis, there are a variety of resources available. This might provide a roadmap for motivated parties to request shapefiles and assemble the dataset. I'm going to make this answer a 'community wiki' in case other people want to flesh it out with more states or hunt further for GIS files on states where PDFs were easier to find..
- Arkansas (map, shp, gdb)
- California (map, shp)
- Connecticut (gdb, shp) Utility Infrastructure and Pipelines
- Illinois (unofficial PDF map)
- Indiana (map, shp)
- Iowa (pdf map)
- Massachusetts (map, shp; town-level detail only)
- Minnesota (.shp, .gdb, .kmz, OGC GeoPackage)
- New Hampshire (pdf map)
- North Carolina (pdf map of co-ops)
- Vermont (.shp)
- Wisconsin (pdf map)
- Bureau of Transportation Statistics Geospatial Information
Atlas of Canada Energy GIS
A website by the Dept of Energy called NEPAnode has this, disclaimer it is a project I manage. You can downloaded these vector datasets in a number of formats including shapefile:
Are you looking for something like the Homeland Infrastructure Foundation - Level Data (HIFLD) Retail Electric Service Territories shapefiles?
This feature class/shapefile represents electric power retail service territories. These are areas serviced by electric power utilities responsible for the retail sale of electric power to local customers, whether residential, industrial, or commercial.
This is the source I use for electric utility service territories:
It is through the US dept of Homeland Security. I can't promise that it is perfect, but this type of geographic info is hard to come by
