The Independent Electricity System Operator (IESO) is asking consumers to reduce their use of electricity as hot weather puts a strain on Ontario's electricity system.

"With the current heat wave we expect to see demand reach near record levels today," said Derek Cowbourne, Chief Operating Officer for the IESO. "Overall, Ontario's transmission system and generators are operating well. But as a precautionary measure the IESO is asking consumers to reduce demand to help ensure the continued reliable supply of electricity."

As a result, consumers and businesses are being asked to reduce their electricity consumption, where possible, from noon until 8:00 p.m. today.

Consumers and businesses can reduce the demands on the electricity system by:

Turning off all but essential internal and external lights;
Setting air conditioners to 26 degrees Celsius (78 degrees Fahrenheit) or higher, or using fans as an alternative;
Closing curtains and blinds to keep out the sun and retain cooler air inside; and
Limiting the use of major power-consuming equipment such as dishwashers, washers and dryers and swimming pool pumps.
The IESO is responsible for managing Ontario's bulk electricity system and operating the wholesale electricity market.
