Time-of-Use Pricing

Time-of-Use (TOU) is Here

The price of electricity in Windsor is calculated using Time of Use rates, in compliance with a mandate from the Ontario Energy Board to promote a culture of conservation in Ontario. Here are answers to some of the questions you may have regarding this change:

What is Time-of-Use Pricing?

Time-of-Use pricing is based on when electricity is used, taking into consideration time of day, time of week (weekday/weekend), and season.

How Does the Time-of-Use Price Structure Work?

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

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

Time-of-Use periods -- off-peak, mid-peak and on-peak will vary between summer and winter. The charts below indicate these periods for summer, winter and weekend/holiday periods:

Why does Ontario have a 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 a range of impacts:

  • Higher demand leads to higher costs, adding 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, so as to reduce impacts on the electricity grid. An Ontario Energy Board (OEB) directive requires energy providers like ENWIN to calculate electricity delivery costs according to the TOU price structure.

How can I benefit from TOU?

Time-of-Use pricing rewards you for using electricity during low-demand (off-peak) periods wherever possible. 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 your laundry weekdays at 5:30 p.m., when you arrive home from work, you will be charged higher (on-peak) rates. Postponing this task until after 7 p.m. can save you money, through lower (off-peak) rates charged.

Is My Energy Usage Still Private?

Smart meters allow for more frequent, accurate readings, telling us how much energy you are consuming and at what time of day. They do not tell us what appliances you are using to consume that energy, or why. Your private information remains, as always, private.
