Time-of-Use Pricing

Time-of-Use (TOU) is Here

The price of electricity in Windsor is now calculated by using TOU rates. By making this change, ENWIN was 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 regarding TOU:

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?

Now that TOU pricing is in effect in Windsor, 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?

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:

You can find out more about these rates by visiting the Electricity prices section of the Ontario Energy Board website.

Why did we change the TOU price structure?

By doing so, ENWIN complied with an Ontario Energy Board (OEB) directive to energy providers like ENWIN to 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 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.

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 are the same summer and winter. Customer who are able to shift the majority of their consumption to Off-peak times of day or days of the week, will benefit through lower electricity rates.

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.

Why did my account number change?

In order to serve you better and to move to TOU pricing, ENWIN has designed and installed a new customer service computer system. In to fully activate this system, ENWIN has provided each customer with a new account number. February 18 onward your bill will show the new account number you will use in the future. This change will have little impact for most customers. However, those who pay their bills online or by telephone banking with their financial institution, will find it necessary to update their payee profiles after receiving their new account numbers.

How will ENWIN help?

Over the next few months, we will work closely with customers and financial institutions to make sure account number transitions and other changes related to Time-of-Use and our new customer service system go as smoothly as possible. We also offer ENWINconnect, which will help you understand your consumption patterns, and find ways to manage your costs.
