The Independent Electricity System Operator (IESO) is asking consumers in the Greater Toronto Area (GTA) to reduce their use of electricity during peak demand times over the next two days.
High temperatures and high humidity levels are resulting in increased demand for electricity through air conditioning use. There are also limitations on the generation and transmission system serving the GTA as a result of equipment outages.
As a precautionary measure, the IESO is asking customers to reduce demand to help relieve the strain on the system serving the GTA. Curtailment efforts can reduce demand and provide additional operating flexibility to help maintain reliability in the area should further problems develop.
Residential and business consumers are being asked to reduce their electricity consumption, where possible, between noon and 8:00 p.m. over the next two days.
Consumers can reduce the demands on the electricity system between noon and 8:00 p.m. by:
Turning off all but essential internal and external lights;
Set air conditioners to 26 degrees Celsius or higher, or use fans as an alternative;
Close curtains and blinds to keep out the sun and retain cooler air inside; and
Limit 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.
