Time-of-Use (TOU) Pricing

Residential and small business customers who choose to be billed under the Time-of-Use (TOU) pricing structure pay different rates for electricity consumed during different times of the day.

There are three TOU periods:

  • on-peak
  • mid-peak
  • off-peak

Prices are highest during on-peak, lower during mid-peak, and lowest during off-peak. TOU prices encourage households and small businesses to use electricity during lower-cost time periods (ex. running your dishwasher and doing laundry at night).

TOU prices are set to be cheapest when demand is lower: during the evenings, on weekends, and on holidays.

TOU price periods are different in the summer than they are in the winter.

Summer TOU Rates

Effective May 1 through October 31.

During the summer, people tend to use electricity more during the hottest part of the day, when air conditioners are running on high.

  • Off-Peak (Weekdays 7pm – 7am, all day weekends and holidays) – 7.4¢/kWh
  • Mid-Peak (Weekdays 7am – 11am and 5pm – 7pm) – 10.2¢/kWh
  • On-Peak (Weekdays 11am – 5pm) – 15.1¢/kWh

How are TOU Rates Set?

The Ontario Energy Board (OEB) determines the tiered rates at the same time as it sets the time-of-use (TOU) rates.

The OEB sets TOU and tiered prices based on its forecast of the cost to supply households and small businesses over the next 12 months. The next rate adjustment is scheduled to take place on November 1, 2023.

If you choose TOU pricing, your electricity bill will include the costs for the electricity that you use during the TOU periods and other costs of delivering electricity.

The Choice Is Yours
