Beginning November 1st 2020, residential and small business customers who currently pay Time-of-Use (TOU) electricity rates will be able to choose a rate plan that best suits their lifestyle and household energy needs by giving them the option of switching from TOU pricing to Tiered pricing.

Since June 1, 2020, customers on TOU have been paying a fixed electricity price of 12.8 ¢/kWh for all hours of the day as part of the government’s response to the COVID-19 pandemic. This fixed price ends on October 31, 2020.

Who is eligible for Customer Choice?

All residential and small business customers who pay Time-of-Use (TOU) rates are eligible. Customers who are not billed under TOU, such as retailer enrolled customers, are not eligible.

What is the difference between Time-of-Use (TOU) and Tiered rates?

The Ontario Energy Board (OEB) sets both Tiered and TOU rates as part of the Regulated Price Plan (RPP) in May and November of every year.

Time-of-Use rates (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. This price applies in the evenings on weekdays and all day on weekends.

Every household and small business is different, but on average, Ontario households use nearly two thirds of their electricity during off-peak hours. 

Mid-peak, when demand for electricity is moderate. These periods are during the daytime, but not the busiest times of 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 (May 1 to October 31) than they are in the winter (November 1 to April 30). 

Tiered Rates

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. 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.

Although May to October 2020 has been an exception due to COVID-19, for residential customers, the threshold normally 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. During the winter period (November 1 – April 30), the Tier threshold for residential customers is 1,000 kWh, so that households can use more power at the 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.

Where can I find more information to help me make an informed decision on which rate option is best for me?

You will be able to choose a plan that best fits your lifestyle and household energy needs, which may result in some cost savings depending on your electricity consumption behaviours. There is no guarantee you will save money if you switch from TOU to Tiered prices. The total bill impact of switching will vary depending on how much electricity you consume in a month and when it is consumed during the day.

To find out how much energy you use, and when you use it please visit NPEI’s My Account customer portal, or if you don’t yet have an online account please register today.
