Earth Hour saves 920 megawatts in Ontario

Independent Electricity System Operator
News Release

********************

TORONTO - The Independent Electricity System Operator (IESO) tonight reported that Ontario demand was reduced by more than six per cent or 920 megawatts (MW) as a result of Earth Hour.

"Ontarians - all across the province - answered the call to action and reduced their electricity use," said Paul Murphy, IESO President and CEO. "The savings were equivalent to what would normally be produced from two coal-fired units in the province."

"Earth Hour reminds us of the importance of using electricity wisely and conserving all year round to benefit the power system and combat climate change," said Murphy.

The IESO is responsible for managing Ontario's bulk electricity power system and operating the wholesale market, every hour, every day. For more information, please visit www.ieso.ca.
