Electricity Rate Selection

Electricity Rate Selection

Since November 1, 2020, there are two electricity rate options that residential and small business customers, who are billed under the provincial Regulated Price Plan (RPP), can choose from: time-of-use (TOU) rates and tiered rates.

As such, residential and small business customers who are billed under the RPP and want to change rate plan can submit a rate selection form to Hydro Ottawa.

So what’s the difference?

Tiered

Time-of-use rates

Under the time-of-use pricing, you pay a different rate for electricity depending on the time of day and day of the week you consume it. Time-of-use has three periods: on-peak (when energy demand and cost is high), mid-peak (when energy demand and cost is moderate) and off-peak (when energy demand and cost is low). The Ontario Energy Board (OEB) set these rates. Learn more about the time-of-use rate structure.

Starting May 1, 2021, time-of-use rates are as follows:

8.2
¢/kWh
OFF-PEAK
11.3
¢/kWh
MID-PEAK
17.0
¢/kWh
ON-PEAK
Tiered

Tiered rates

Customers under tiered rates pay one set rate for the electricity they consume up to a predetermined kilowatt-hour (kWh) threshold each month. Once customers exceed the monthly threshold, they are billed at a higher rate per kWh for all additional electricity consumed in that month.

The threshold changes with the seasons for residential customers:

  • In the summer period (May 1 – October 31), the Tier threshold for residential customers is 600 kWh.
  • In the winter period (November – April) the Tier threshold for residential customers is 1000 kWh.

The Tier threshold for small business customers is 750 kWh all year round.

The Ontario Energy Board (OEB) set these rates. Learn more about tiered pricing.

Starting May 1, 2021, tiered rates and thresholds are as follows:

 
Residential
First 600 kWh: 9.8 ¢
Above 600 kWh: 11.5 ¢
 
Business
First 750 kWh: 9.8 ¢
Above 750 kWh: 11.5 ¢

Are you considering a switch?

To better understand the potential impacts of a rate change on your bill, it’s important to know what your overall energy consumption is and how your day-to-day habits can influence your energy costs.

The information contained on your Hydro Ottawa MyAccount customer portal should be a good indicator of your consumption habits and electricity usage history. If you don’t have an online account, you can easily create one today.

Once in MyAccount, have a look at some of your past electricity bills and consider the following:

Your price plan

Do you pay TOU or tiered prices for your electricity?

Your consumption pattern and your usage

When do you use electricity and how much electricity do you use in a month?

Lifestyle and daily habits

Are you often home during the day on weekdays, so that shifting your usage is more challenging? Do you have large appliances that you need to run during the day on weekdays? Can you shift more of that usage to nighttime or weekend hours?

You should also keep in mind the effect of COVID-19 on your electricity consumption (for instance, you may be working from home when you normally wouldn’t be).

Are there any tools available to help me compare rate plans?

There are two different online tools available to help customers make a choice and compare TOU and tiered rate plans.

Hydro Ottawa’s rate plan comparison tool is available for MyAccount customers and automatically uses your consumption data to show you the electricity cost difference (in percentage) under TOU or tiered prices for your account.

There’s no need for you to enter any consumption data or other billing information when using Hydro Ottawa’s rate plan comparison tool. MyAccount will automatically generate an estimate and compare electricity costs for you based on the historical monthly usage information available in your MyAccount customer portal.

The online tool is easy-to-use. Simply follow these steps:

  • Log into MyAccount
  • Choose ‘’Manage Rate Plan’’ option;

    Rates - Manage Rate Plan
  • Click on the “Compare Rate Plans’’ button.

    Rates - Request Rate Change

More information on Hydro Ottawa’s online tool is available in our Rate Options FAQs.

If you are not yet registered to MyAccount, but wish to use this tool, you can sign up today at hydroottawa.com/myaccount.

A second one is available through the Ontario Energy Board’s (OEB) website. The OEB’s bill calculator will help you compare your estimated monthly bill under TOU or tiered prices.

Unlike Hydro Ottawa’s MyAccount rate plan comparison tool, when using the OEB’s bill calculator you will need to enter your consumption information into the tool manually to receive your billing comparison. Be sure to have copies of your previous bills available on hand to assist you in entering accurate consumption information.

Where can I find more information?

You can read our Frequently Asked Questions (FAQ’s). Alternatively, you can also contact us online or by phone at 613-738-6400.

The Ontario Energy Board also has information on the Customer Choice program available at oeb.ca/choice.

Is there a deadline to choose between the two rate plans?

There is no deadline to choose. You can request to change your rate plan at any time.

If you don’t wish to make a change, there is nothing you need to do. You’ll continue to be billed under your current rate plan. The option to change rate plan will always be available.

How do I change my rate plan?
