YORK REGION and SIMCOE COUNTY, ONTARIO--(Marketwire - March 31, 2012) - Earth Hour 2012 saw thousands of PowerStream customers, in the nine municipalities served by the electric utility, indicate their willingness to help fight climate change by turning off their lights for 60 minutes to reduce electricity consumption.

PowerStream's System Control Centre reported a service territory-wide 7.8 percent electricity consumption reduction between 8:30 p.m. and 9:30 p.m. on Saturday*. This was a decrease from the 8.9 percent reduction achieved collectively last year by customers in PowerStream's service territory during Earth Hour 2011.
