The city of Port Coquitlam, British Columbia, Canada, has installed nine LED streetlight fixtures as part of a pilot program to test energy efficient streetlight technology. An additional 60 LED fixtures are scheduled to be installed in a concurrent pilot project. The city is also installing an adaptive control system to determine the full potential of energy savings of the LED luminaires. The pilot installation is located in downtown Port Coquitlam on Shaughnessy Street and Broadway Street and will be running through December 2010. The project is funded by Port Coquitlam in cooperation with B.C. Hydro, the local utility.
The city currently owns and maintains 2,763 ornamental streetlights and leases 780 traditional roadway lights from B.C. Hydro. The fixtures replaced in the pilot study with LED streetlights were 200 watt high pressure sodium (HPS) streetlights. The replacement streetlights, supplied by LED Roadway, a manufacturer located in Nova Scotia, Canada, are 110 watt equivalent fixtures that reduce energy consumption by almost 50%. In addition to cost savings, the city expects the LED luminaires to provide lighting comparable to what the HPS fixtures provided. “Our energy savings are expected to be 50% with an additional 35% savings coming from the adaptive controls,” said Allen Jensen, manager of environmental services for the city of Port Coquitlam. Actual dollar savings will be determined after the pilot study is concluded.
“We plan on converting all of our streetlights to LEDs within the next five years, which may be fast tracked depending on the B.C. Hydro incentive program,” said Jensen.
Port Coquitlam is interested in testing and measuring the performance of the adaptive control system, supplied by Streetlight Intelligence, a company located in British Columbia. The adaptive control system will allow light levels to be adjusted based on the time of day, which could reduce energy consumption significantly.
