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.

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.
