RPP Time-of-Use Pricing (TOU)

What is Time-of-Use Pricing?

TOU pricing is based on the actual time that electricity is used, including the time of day, day of the week (weekday/weekend), and season.

How Does the Time-of-Use Price (TOU) Structure Work?

Prices for electricity will vary according to demand levels at given times of day. Higher prices will be charged during on-peak periods, when demand is highest. Lower prices will be charged during mid-peak and off-peak periods, when demand is lower.

What are the TOU rates, and when are they in effect?

TOU periods - off-peak, mid-peak, and on-peak - will vary between summer and winter. The charts below show these summer, winter, and weekend/holiday periods:

We calculate electricity delivery costs according to the TOU price structure.

When we all use a lot of electricity at the same time, we create peak demand periods. And supplying electricity at those peak times has many impacts:

  • Higher demand leads to higher costs, which adds to provincial electricity costs.
  • It's hard on the environment because it adds to the amount of new generation, transmission and distribution infrastructure Ontario must build.
  • It puts a strain on our electricity system.

TOU pricing is intended to encourage consumers to use electricity during off-peak times, to reduce the impact on the electricity grid.

One Week Time-of-Use Chart

These charts show weekly calendars for Time-of-Use price periods - one for summer and one for winter. Green represents off-peak hours, which total 64% of the total week, and stay the same summer and winter. If you can shift most of your consumption to off-peak times, you will benefit from lower electricity rates.

How can I benefit from TOU?

Time-of-Use pricing rewards you for using electricity during low-demand (off-peak) periods whenever you can. By making simple changes to the times of day you run major appliances, you will be able to keep your costs as low as possible. For example, if you do laundry on weekdays at 5:30 p.m., you will be charged higher (on-peak) rates. Waiting to do laundry after 7 p.m. can save you money, because lower (off-peak) rates will be charged.

Will My Energy Usage Still be Private?

We will be able to see how much energy you are consuming and at what times. But we will not see how you consume energy, or why. Other than allowing more frequent, accurate readings, nothing will change. Your private information will remain, as always, private.
