The Independent Electricity System Operator (IESO) has ended the Power Warning as of 8:00 p.m. The IESO earlier restored voltage to normal following a four-hour reduction.
"We thank those customers who were able to respond to our request to reduce electricity consumption today," said Paul Murphy, Chief Operating Officer for the IESO.
While the Power Warning ended at 8:00 p.m., the Power Advisory will remain in effect until 6:00 p.m. Friday.
The IESO issues a Power Advisory when supplies of power, including imports, are forecast to be adequate, but the expected high demand will put a prolonged strain on the electricity system. Conservation measures will benefit consumers, the environment and the electricity infrastructure. Power Advisories can last for an extended period of time.
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 or higher, or using fans as an alternative;
- Closing curtains and blinds to keep out the sun and retaining cooler air inside; and
- Avoiding or limiting the use of major power-consuming equipment such as dishwashers, washers and dryers and swimming pool pumps between the hours of 8:00 a.m. and 800 p.m.
The IESO is responsible for managing Ontario's bulk electricity system and operating the wholesale electricity market. For more information, visit www.ieso.ca.
