IESO appeals for reduced electricity consumption in the GTA
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.

Prices per kilowatt-hour were set by utility commissions after lengthy testimony from power companies, wanting higher rates, and consumer groups, wanting lower rates.
About 25 years ago, the electricity landscape started to change as economists and others argued that competition could lead to lower prices and stronger grid reliability. Opponents of competition argued that consumers weren’t knowledgeable enough about power markets to make intelligent choices…
