Client: City of Chicago Department of Transportation (CDOT) Division of Electrical Operations

Advisor: City of Chicago Department of Innovation & Technology (DoIT) GIS Program

Technical Lead: Urban GIS

Stakeholder: Commonwealth Edison (ComEd)

Entire CDOT streetlight inventory contained within over 900 maps of a paper-based atlas

Updates maintained by hand

Challenge of sharing information

In 2013 ComEd contracted for a field inventory of the City's lighting

GPS of structure locations and wattage information

CDOT performed quality review to ensure accuracy

Urban GIS was contracted in 2013 to develop the streetlight database

City of Chicago pays approximately $15 M annually to ComEd for powering street, alley, & underpass lights as part of their unmetered accounts.

This also includes over 2900 intersections with traffic signals

Both ComEd and CDOT maintained discrepant inventories of streetlight assets

The bills are calculated based on wattage of fixtures and hours of operation (e.g., dusk-to-dawn)

Accuracy of the electric bill is reliant on the accuracy of the database
