Electricity Rates

CURRENT RATES AND SCHEDULE – EFFECTIVE MAY 1, 2022

The Ontario Energy Board (OEB) has announced summer Time-of-Use (TOU) hours, and the summer Tier threshold for residential customers to begin on May 1, 2022, and run until October 31, 2022.

 


 

The TOU and Tiered prices set by the OEB under the Regulated Price Plan (RPP) are shown in the table below. The table also shows the hours to which those prices apply:

Types of Electricity Rates

For residential and small business customers that buy electricity from their utility, there are two different types of rates (also called prices here). The Ontario Energy Board sets both once a year on November 1:

 

Time-of-Use (TOU)

With TOU prices, the price depends on when you use electricity.

There are three TOU price periods:

  • Off-peak, when demand for electricity is lowest. Ontario households use most of their electricity – nearly two-thirds of it – during off-peak hours.
  • Mid-peak, when demand for electricity is moderate. These periods are during the daytime, but not the busiest times of the day.
  • On-peak, when demand for electricity is generally higher. These are the busier times of day – generally when people are cooking, starting up their computers and running heaters or air conditioners.

With TOU pricing, you can help manage your electricity costs by shifting your usage to lower price periods when possible.

People use electricity differently depending on the season, so the TOU price periods are different in the summer than they are in the winter. No matter which season, on weekends and holidays the cheapest rates are in effect all day. View the Time-of-Use holiday schedule.

 

Tiered

With Tiered prices, you can use a certain amount of electricity each month at a lower price. Once that limit (called a threshold) is exceeded, a higher price applies. The threshold changes with the season to reflect changing usage patterns – for example, there are fewer hours of daylight in the winter and some customers use electric heating. 

In the winter period (November 1 – April 30), the Tier threshold for residential customers is 1,000 kWh, so that during the heating season households can use more power at a lower price. In the summer period (May 1 – October 31), the Tier threshold for residential customers is 600 kWh. The Tier threshold for small business customers is 750 kWh all year round.

Tiered prices give you the flexibility to use electricity at any time of day at the same price, although that price will change if you exceed the threshold during the month.
