Time-of-Use Pricing (TOU)
TOU is Here
The price of electricity in Windsor is now calculated using TOU rates. By making this change, we are complying 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 about 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:

Why did we change the TOU price structure?
We changed to comply with an Ontario Energy Board (OEB) mandate, directing that 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.
Why did my account number change?
To serve you better, and to move to TOU pricing, we designed and installed a new customer service computer system. To activate this system, we gave each customer a new account number. Your bill will show the new account number. This change will have little impact for most customers, but if you pay your bill online or by telephone banking, you will need to update your payee profile after getting your new account number.
How will ENWIN help?
We will work closely with customers and financial institutions to make sure account number transitions, and other changes related to TOU and our new customer service system, go as smoothly as possible. We also offer myENWIN, which will help you understand your consumption patterns, and find ways to manage your costs.
