Customer Choice
Customer Choice is an Ontario Energy Board (OEB) initiative that allows Regulated Price Plan (RPP) customers to choose their electricity price plan.
Residential, small business and net metering customers billed under the RPP can choose the electricity rate that best meets their energy needs and lifestyle: Time-of-use, Tiered or Ultra-low overnight prices.
Hydro Ottawa offers four easy ways to make the switch and change rate plan.
So what’s the difference?
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).
Time-of-use periods (hours) are different in the summer than they are in the winter.
The Ontario Energy Board (OEB) set these rates. Learn more about the time-of-use rates and structure.
Effective November 1, 2024, Time-of-use customers are charged:
| TOU Price Periods | Winter (Nov. 1 to April 30) | Summer (May 1 - Oct. 31) | TOU Prices |
|---|---|---|---|
Off-Peak | Weekdays 7 p.m. to 7 a.m. | Weekdays 7 p.m. to 7 a.m. | 7.6 ¢/kWh |
Mid-Peak | Weekdays 11 a.m. to 5 p.m. | Weekdays 7 a.m. to 11 a.m. and 5 p.m. to 7 p.m. | 12.2 ¢/kWh |
On-Peak | Weekdays 7 a.m. to 11 a.m. and 5 p.m. to 7 p.m. | Weekdays 11 a.m. to 5 p.m. | 15.8 ¢/kWh |
Similar to Time-of-use rates, with Ultra-low overnight, the price depends on when you use electricity. Ultra-low overnight has an additional price period, a different set of rates and offers an ultra-low overnight rate in exchange for a higher on-peak rate.
With Ultra-low overnight pricing you are charged according to the day of the week and time of day that you use electricity. There are four price periods: on-peak, mid-peak, weekend off-peak, and ultra-low-overnight. The Ultra-low overnight plan sets a very low price for the overnight period, however, the on-peak price is significantly higher.
This plan could be beneficial to those who consume a major portion of their electricity overnight, or to those who charge an electric vehicle overnight.
The Ultra-low overnight periods (hours) are the same in the summer as they are in the winter.
The Ontario Energy Board (OEB) set these rates. Learn more about the Ultra-low overnight rates and structure.
Effective November 1, 2024, Ultra-low overnight customers are charged:
| ULO price periods | All year | ULO Prices |
|---|---|---|
Ultra-low overnight | Everyday 11 p.m. to 7 a.m. | 2.8 ¢/kWh |
Weekend off-peak | Weekends and holidays 7 a.m. to 11 p.m. | 7.6 ¢/kWh |
Mid-peak | Weekdays 7 a.m. to 4 p.m. and 9 p.m. to 11 p.m. | 12.2 ¢/kWh |
On-peak | Weekdays 4 p.m. to 9 p.m. | 28.4 ¢/kWh |
With Tiered rates, the price depends on how much electricity customers use overall in a month
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. The threshold for small business customers is the same all year round.
The Ontario Energy Board (OEB) set these rates. Learn more about tiered rates structure and pricing.
Effective November 1, 2024, Tiered rates customers customers are charged:
| Tier Thresholds | Winter (Nov. 1 to April 30) | Summer (May 1 to Oct. 31) | Tiered Prices |
|---|---|---|---|
Tier 1 | Residential – first 1,000 kWh/month Small business – first 750 kWh/month | Residential – first 600 kWh/month Small business – first 750 kWh/month | 9.3 ¢/kWh |
Tier 2 | Residential – for electricity used above 1,000 kWh/month Small business – for electricity used above 750 kWh/month | Residential – for electricity used above 600 kWh/month Small business – for electricity used above 750 kWh/month | 11.0 ¢/kWh |
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 Time-of-use 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?
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 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 Time-of-use or tiered prices for your account.
With MyAccount, 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.
NOTE: The Ultra-low overnight rates are not available in the MyAccount rate plan comparison tool. If you wish to compare your electricity costs using Ultra-low overnight rates, please use the OEB bill calculator to estimate your monthly bill.
Hydro Ottawa’s online tool is easy-to-use. Simply follow these steps:
- Log into MyAccount
- Choose ‘’Manage Rate Plan’’ option;

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.
You can use the Ontario Energy Board’s bill calculator to compare your estimated monthly bill under Time-of-use, Ultra-low overnight and Tiered price plans.
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.
