Program Description

The City of Flint, MI began the initial street lighting inventory process in preparation for suitable retrofit opportunities under the existing Consumers Energy LED street lighting program. Flint was challenged by limited staffing and funding resources along with re-prioritization of public service infrastructure projects.

Service Area

City of Flint municipal street lights.

Situation Highlights

Flint’s system consists of about 11,600 mercury vapor and high-pressure sodium street lights that use a total of about 18.5 MWh per year in electricity, worth about $2.5 million. Street light facilities staff conducted a full inventory and system-wide assessment, complete with GIS mapping of poles and fixtures. The initial financial review (See below) showed a promising ROI on a full-scale replacement project. While all lights are owned by Consumers Energy, there was some early indication of the utility’s willingness to collaborate with the city to achieve favorable terms for a street light replacement project.
