Conservation Efforts Need to Continue Throughout the Day

August 18, 2003

August 18, 2003 (11:00 a.m. EDT) 

Conservation efforts by Ontario electricity consumers are already making an impact on overall demand today. As of 11:00 a.m. this morning, demand was 17,250 MW. 

Ontario generation capability for today is expected to reach 19,700 MW. Normal consumption on a day like today would be 22,000 to 24,000 MW. This does not include a required reserve margin of at least 1500MW. It is critically important for industries, businesses and residential consumers to continue to curtail their power use, as this will be one key factor in avoiding rotating power outages. 

Ontario Premier Ernie Eves has asked large manufacturers to assist with conservation efforts by operating at 50% of their normal power usage. Commercial and retail businesses are also being asked to conserve energy by reducing their consumption to 50% of normal usage. The IMO requests that all market participants do their part. 

These conservation efforts are required to ensure there is enough power to meet demand for the week and to provide for essential services such as hospitals, water treatment plants and the oil and gas industries. 

The IMO is providing hourly updates on current demand on its Web site: www.ieso.ca.
