Ontario, Canada

The Ontario’s power system is managed by The Independent Electricity System Operator (IESO). The operator ensures there is enough power to meet the province’s energy needs in real time while also planning and securing energy for the future. The level of demand in Ontario is primarily influenced by factors like weather, hours of daylight, business hours, school holidays, and daily consumption patterns. At certain times of the year demand in the middle of the night can go lower than 11,000 megawatts (MW) and then rise by more than 10,000 MW later the same day.
