Time-of-Use pricing provides the ability to reduce cost by shifting some electricity use to lower cost periods. Under Time-of-Use pricing, the cost varies depending on the time of day or day of the week that electricity is used.
There are three Time-of-Use periods identified:
- Off-Peak (24 hours a day on weekends and holidays as well as weekday evenings after 7pm): the demand for electricity and the cost is lowest during this time. Ontario households use most of their electricity – nearly two thirds of it – during off-peak hours.
- Mid-Peak (Weekdays only 11am to 5pm in the winter months, morning and early evening in the summer months):
- On-Peak (Weekdays 7 am to 11am and 5pm to 7pm in the winter. 11am to 5pm in the summer): times of the day when energy use and price is the highest.
