Program Description

The city issued an RFP for “Conversion of City Street Lights to LED Fixtures and Transfer of Ownership from Utility to Municipality”.The project covered the LED conversion of all municipal streetlights as well as the lighting in parking structures. In 2016 most street lights were owned by Central Maine Power (CMP), and were 50 or 75 W HPS.

Service Area

The City of Portland, ME.

Situation Highlights

In Maine, the investor owned utility owns nearly all of the municipal streetlights in the state. The state recently enacted legislation that requires the utility to sell the lighting equipment to any municipality that wishes to purchase it. The Public Utilities Commission has created rules and tariffs to enable the legislation. No municipality has yet done so but the City of Portland along with the South Portland, Falmouth, Biddeford, and Rockland have selected firms to assist with the purchase and replacement of the lights. Each of the towns were planning on starting negotiations with the utility in 2017.
