Canadian city Ottawa successfully slashes costs with LED streetlights

Canadian City Ottawa has reported new LED streetlights installed since Fall last year have helped cut energy bills by nearly 75 percent, according to local paper The Times report.

The fourth largest city in Canada swapped old halogen lights in exchange for the new LED streetlights. The streetlights performance of cutting energy consumption by 75 percent comes close to previous estimations of 79 percent.

According to engineer Dave Noble the lights have been able to save 75 percent in electricity bills, bringing the previous energy bill of CA $590 from old streetlights to CA $ 150 (US $136.69).

The LED bulbs were paid for with a $9,056 Illinois Clean Energy Foundation grant.

Another Canadian city Calgary is also rolling out LED streetlight upgrade plans.

The city council announced at the end of July 2014 plans of replacing high-pressure sodium streetlights with energy efficient lights, according to a report by The Calgary Journal. The new lights are expected to slash energy consumption by 55 percent.

Calgary’s streetlight retrofit plan is expected to cost at least CA $23.7 million for 19,500 streetlights out of a total of 90,000 streetlights. Investments made to install the lights are expected to be recouped within 10 years.
