The Public Service Commission of Wisconsin (PSCW) develops and maintains a variety of statewide Geographic Information System (GIS) databases for the energy industry in Wisconsin.  A number of maps have been created from those GIS databases that contain information about Wisconsin’s natural gas systems.  Maps and databases are updated as new data becomes available.  The locations of natural gas facilities and service territories are accurate only to the extent that the various sources supplied accurate data.  PSCW staff will continue to update and improve the GIS data and maps.

Due to homeland security critical infrastructure issues, the distribution of maps showing natural gas facilities may be restricted.  Therefore only the small and medium service territory maps are available for download free of charge.  Paper copies of any of the maps may be ordered.

Natural Gas Service Territories – Updated 2010

Small (8.5” x 11”)
Medium (11” x 17”)

Natural Gas Utility Service Territories & Natural Gas Transmission Pipelines – Updated 2010
Natural gas service territories of local distribution companies (LDC) are shown, as well as transmission and Guardian lateral pipelines identified by owner.  The map identifies county and township boundaries, major highways, and water bodies.
