PowerStream Reports 8.9% Less Electricity Used During Earth Hour 2011

Percentage Reduction for Service Territory Slightly Down From Previous Year's Results

YORK REGION & SIMCOE COUNTY, ONTARIO--(Marketwire - March 26, 2011) - Earth Hour 2011 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 reported a service territory-wide 8.9 percent electricity consumption reduction between 8:30 p.m. and 9:30 p.m. on Saturday*. This was slightly down from the 9.1 percent reduction achieved collectively last year by customers in PowerStream's service territory during Earth Hour 2010. According to the Independent Electricity System Operator (IESO), the Earth Hour results this year were somewhat muted across the province due to colder temperatures and the need for more electricity to heat some homes and businesses.

The 2011 results represented a total savings of 86.7 megawatts (MW) in peak demand, or enough electricity to power 2,627 average-size homes over a 24-hour period. The reductions achieved per municipality in 2011 were as follows:

    % Reduction*   MW Reduction*
Aurora   14.3%   7.4 MW
Barrie   7.7%   9.9 MW
Bradford West Gwillimbury   9.1%   2.3 MW
Essa (Thornton)   18.0%   0.2 MW
Markham   8.5%   23.0 MW
New Tecumseth   9.2%   2.0 MW
Penetanguishene   6.6%   0.6 MW
Richmond Hill   9.3%   12.9 MW
Vaughan   8.8%   28.4 MW
PowerStream Service Territory   8.9%   86.7 MW
* (in comparison to a typical consumption pattern normally experienced on a similar type of day, taking into consideration hour of the day, time of year and weather).

PowerStream also supported Earth Hour 2011 in several other ways. In addition to powering down the lights at its three work locations in Barrie, Markham and Vaughan, the company also was the presenting sponsor of the Barrie Earth Hour Music Festival and provided sponsorship support to the Woodbridge Earth Hour Lantern Walk.

"The recent disaster in Japan reminds us that we all share the same home. The results from this year's Earth Hour demonstrates that many of our customers want to do something positive for our planet," Town of Markham Mayor Frank Scarpitti, who also serves as PowerStream's Board Chair, said.

Brian Bentz, President and CEO of PowerStream, agreed that participation in this year's Earth Hour carried an even greater significance than in previous years.

"Earth Hour is a symbolic event for residents to show their support to help fight climate change and shed light on how we can all make a difference by reducing our electricity consumption," said Brian Bentz, President and CEO of PowerStream. "We are pleased with our customers' response as participants in this global event."
