IESO Appeals for Reduced Electricity Consumption

August 2, 2007

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. For more information, visit www.ieso.ca

PUBLIC APPEALS

In periods of tight electricity supplies, the IESO may issue a public appeal urging consumers to reduce electricity consumption. Typically, public appeals are issued when extreme weather or unexpected generator outages stretch the system's ability to provide enough electricity to meet demand and required levels of reserve.
