1. City of Portland, Maine LED STREET LIGHT and SMART CITY PROJECT OVERVIEW September 21, 2017

2. Background:
Most cities in the United States obtain their Street Lights through their local utility and pay for them out of their operational budget
While lighting technologies have evolved over time, most street lights have the following in common:
Use a lot of electricity
Fail often (every 2-3 years)
Require a maintenance contract with the local utility
Portland spends over $1.1M per year for street lights

3. The Opportunity:
LED technology is the most cost effective street lighting solution.
The ME Legislature passed legislation allowing cities to purchase street lights from Central Maine Power and convert them to LED
Staff worked with TCS & Bernstein Shur to negotiate a P&S agreement for the CMP owned lights.
The value of the existing lights is determined by a formula mandated by the ME PUC.
Cost to buy out our lights ~ $590,000

4. Street Light examples
Cobra Head
Flood light

5. How Portland saves money:
Currently, the cost of streetlights has 3 components:
Electricity supply – Next Era, Constellation, others
Electricity distribution (sending it across wires) – CMP
Rental of lights and equipment, maintenance – CMP
Once Portland purchases the lights and upgrades them to LED, we will be saving:
2,648,357 kilowatt hours saved
Savings in lighting rentals and maintenance from CMP
Overall, we will save almost $1M per year
