Traffic Signal Conversion to LED Technology Program

The City of Moncton Traffic Signal Conversion to LED Technology Program is an energy management program aimed at reducing energy consumption, energy cost, and greenhouse gas carbon dioxide (CO2) emissions. The Program consisted of upgrading traffic light installations by replacing incandescent wattage bulbs to low emitting diode (LED) lamps to reduce energy consumption, and was completed in March 2006. All traffic lights use LED technology, and the city holiday lights are now being converted to LED.

With these new LED lights, savings in electrical energy consumptions are estimated to be approximately 82 per cent of the previous traffic light energy usages. Besides the energy consumption reduction and financial incentives, the traffic light conversion program has reduced the city’s greenhouse gas emissions.

This reduction in emissions happens at the power supply source by substantially reducing the power consumption requirements of the traffic signals.

With the financial assistance from the province of New Brunswick’s Environmental Trust Fund (ETF), the City of Moncton completed Phase 3 of the Traffic Signal Conversion to LED Technology Program as of March 2006.

The completion of this Program resulted in an annual energy reduction of 715,000 kWh/hr, an annual CO2 reduction of 536 metric tons and annual energy cost savings of more than $87,000. The payback period for the city to recuperate the expenditures from the cost of the energy savings was approximately 27 months with the financial assistance from the Environmental Trust Fund.

Moncton now uses LED technology in all new traffic lights, and is converting decorative lights in parks to LED. The city is also piloting a project to place LED lights in streetlights.
