On November 1, 2019, the Ontario government introduced the Ontario Electricity Rebate (OER) under the Ontario Ontario Rebate for Electricity Consumers Act, 2016.
The Ontario Electricity Rebate reduces the pre-HST costs on customers’ bills by 13.1%.
Low-volume consumers with a monthly demand less than 50kW or consumption less than 250,000 kWh are automatically eligible.
The following customer types are eligible:
- Low volume accounts (meaning the account has a demand for electricity of 50 kilowatts or less, or uses not more than 250,000 kilowatt hours of electricity per year); this includes residential and many small business customers;
- Farms;
- Long-term care homes; and
- *Multi-unit complexes that are predominantly residential, such as condominium and apartment buildings.
*Multi-unit complexes that are predominantly residential, such as condominium and apartment buildings must complete and submit the OER Self-Declaration form to Hydro Ottawa to attest their eligibility.
For a definition of all of the above terms please refer to the OER Self-Declaration form.
Did you know? If your account is a low volume account, such as ‘’residential and small business customers’’ or relates to a farm or a long-term care home, you don’t need to sign up to receive the rebate. The rebate is applied automatically to your Hydro Ottawa bill each month.
If you have one of these accounts but you are not already receiving the OER, please contact us. If you are not sure whether you are already receiving the OER, check your last Hydro Ottawa bill.
Effective July 1, 2022, the Ontario government expanded eligibility for some residential and other low volume consumers:
- Common areas in individually metered multi-unit complexes that contain at least 50 per cent residential units, such as condominiums;
- Retirement residences that are not long-term care homes, but do not meet eligibility criteria as a residential multi-unit complex; and
- Residential mobile home parks.
For a definition of the above terms please refer to the OER Self-Declaration form or Frequently Asked Questions (FAQ’s).
Notice Requirements
In order to receive the OER, consumers who now qualify under the expanded eligibility requirements will need to submit the OER Self-Declaration Form to Hydro Ottawa in which you attest your eligibility.

You have two options for electricity supply.
You can buy electricity from Hydro Ottawa through the Regulated Price Plan (RPP) where prices are set by the Ontario Energy Board (OEB), or sign a contract with a company that sells electricity, also known as an electricity retailer.
If you buy your electricity under the RPP, there are different types of price plans to choose from: Time-of-use (TOU), Tiered, or Ultra-low overnight (ULO) rates.
Time-of-Use (TOU) – TOU has three price periods, and you pay a different rate for electricity depending on the time of day and day of the week you consume it. Prices are highest during on-peak, when energy demand and cost is high, medium during mid-peak, when energy demand and cost is moderate, and lowest during off-peak when energy demand and cost is low.
Ultra-Low Overnight (ULO) – Similar to TOU rates, under ULO, the price depends on when you use electricity. ULO has an additional price period, different set of rates and offers an ultra-low overnight rate in exchange for a higher on-peak rate.
With ULO 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 ULO 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.
Tiered rates – Under tiered rates, you can use a certain amount of electricity each month at a lower rate up to a predetermined kilowatt-hour (kWh) amount called a ‘’threshold’’. Once you exceed the monthly threshold, you are billed at a higher rate per kWh for all additional electricity used in that month.
Residential and small business customers are automatically part of the RPP unless they choose to purchase their electricity from an electricity retailer.
If you have your electricity supplied by Hydro Ottawa through the RPP and want to change your rate plan, you must notify Hydro Ottawa.
You can visit our electricity rate selection web page and 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.
There are two different online tools available to help customers make a choice and compare TOU, tiered, and ULO 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.
Currently, ULO rates are not available in the MyAccount rate plan comparison tool. If you wish to compare your costs using ULO rates, please use the OEB bill calculator.
Hydro Ottawa’s online tool is easy-to-use. Simply follow these steps:
- Log into MyAccount
- Choose ‘’Manage Rate Plan’’ option;
Image
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, ULO or Tiered prices.
These tools are designed to provide customers with an estimate on whether they may benefit financially from making a switch to a different rate plan. The tools are intended to act as a guide only, and actual differences will depend on usage and consumption patterns within any billing period.
There is no deadline to change rate plan. 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 will always be available.
Your rate change request will be processed up to 10 business days after receiving your Rate Selection Form. Once your form has been fully processed, your new rate plan will take effect on the first day of your next billing period or the following one, depending on where you are in your billing period.
For example:
If your billing period is from November 15 to December 14, and you requested to change your rate plan on November 24, your new rate plan will be effective on December 15.
The date on which you should start using electricity based on your new rate plan is the first day of your billing period on your new rate plan.
Yes, following the prescribed process and timelines, you can change your rate plan at any time.
Note: If you have already submitted a rate change request, you need to wait until this initial request has been fully processed before submitting another one.
As a general rule, electric heating operates more often at night when the temperature drops. This is also when electricity is the cheapest.
In a 168-hour week, only 30 to 40 hours (depending on season) are at On-Peak times. There are nearly three-times as many hours at Off-Peak rates.
From May 1 to October 31
- Off-Peak (7 p.m. to 7 a.m. and all day weekends and holidays)
- Mid-Peak (7 a.m. to 11 a.m. and 5 p.m. to 7 p.m.)
- On-Peak (11 a.m. to 5 p.m.)
From November 1 to April 30
- Off-Peak (7 p.m. to 7 a.m. and all day weekends and holidays)
- Mid-Peak (11 a.m. to 5 p.m.)
- On-Peak (7 a.m. to 11 a.m. and 5 p.m. to 7 p.m.)
For more information, visit the time-of-use page.
Similar to TOU rates, with ULO, the price depends on when you use electricity. ULO 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 ULO 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 ULO 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 ULO periods (hours) are the same in the summer as they are in the winter.
This plan is in large part intended for customers who can shift their electricity use to periods of low demand, away from on-peak hours.
- Ultra-low overnight (everyday 11 p.m.to 7 a.m.)
- Mid-peak (weekdays 7 a.m. to 4 p.m. and 9 p.m. to 11 p.m.)
- On-peak: (weekdays 4 p.m.to 9 p.m.)
- Weekend off-peak: (weekends and holidays 7 a.m.to 11 p.m.)
For more information, visit the Ultra-Low Overnight page
Tiered rates give you the flexibility to use electricity at any time of day at the same price, but that rate will go up if you exceed the threshold during the month.
For more information, visit the tiered rates page.
The threshold 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.
In the winter period (November 1 – April 30), the tier threshold for residential customers is 1,000 kWh
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.
For customers that have signed up for a contract with an electricity retailer, the price is set out in the contract which is not regulated by the Ontario Energy Board.
An electricity retailer contract covers only some parts of your bill. You will continue to pay other charges to Hydro Ottawa regardless of whether you sign a contract with an electricity retailer.
Once you close your account, you may still view up to two years of electricity consumption based on your regular bill intervals. Time-of-use information is only available for active accounts.
Time-of-use information will only appear if your online account is active.
If you’ve closed your electricity account and moved to a new location within our service territory, you can add your new electricity account to your existing online account profile. This will allow you to view Time-of-use data for your new electricity account. You will continue to have access to previous consumption and billing information.
Occasionally there may be communication difficulties between your meter and Hydro Ottawa's meter data collectors. Metering data is stored within your meter and may be collected once the connection is re-established. Contact us if this problem persists.
Recent consumption data is considered "unbilled usage" because it has not yet been validated by the provincial Meter Data Management and Repository (MDM/R). The MDM/R is a common platform for processing, storing and managing all Smart Meter data within Ontario. Once your consumption data has been validated and obtained from the MDM/R, the values may change.
The following message appears on all time-of-use pages:
*Note: Unbilled electricity consumption has not been loss-adjusted and may contain estimated data.
Your meter displays the following pieces of information in sequence:
- A segment test where all parts of the display are turned on at once to ensure they are still functioning
- Your kWh consumption in a five-digit format
- A communications network address identification number for Hydro Ottawa’s use.
Hydro Ottawa issues bills on a monthly basis and you will receive your first bill within four to six weeks of opening an account.
New accounts are subject to an Account Set-up Charge. This charge also applies when a customer moves from one address to another.
If you wish to close or transfer an active account on behalf of someone else (i.e. deceased relative, family member or close friend) please contact us at 613 738-6400 and our customer service representatives will be happy to assist and work with you. Due to strict privacy guidelines, we will ask you to provide important documentation such as the following.
- The account number and name of the account holder;
- Your relationship to the deceased; and
- A copy of proof of executor or Power of Attorney documentation.
Please note that if you wish to transfer and take responsibility for the active account yourself, you must be listed as the secondary account holder.
A credit balance on a closed account may be transferred to another account under the same name to pay off outstanding balances. If there is no outstanding balance and the credit is $5 or greater, it will be returned to the account holder via a cheque to the new mailing address 21 days after the final bill has been issued. Please allow an additional 10 days to receive it.
If you are receiving support through OESP, your final credit will be prorated depending on the number of days of service and any remaining credit will be returned to the Program as OESP is not a cash commodity.
If you have a credit balance due to payments from other financial support programs such as Ontario Works (OW) or Ontario Disability Support Program (ODSP), we will work directly with that agency to determine if you are eligible for a refund.
If you’ve entered into an Arrears Payment Agreement, it will be cancelled and any remaining balance will be applied to your final bill and become due.
Yes, if you are an EMPP customer, your account will be reconciled and any credits owed or outstanding charges will be applied to your final bill.
Your final bill will be ready approximately 3 weeks after your last day of service and will include the charges up to the day your service ended.
If you are moving out and want to end your Hydro Ottawa service and close your account, you will need to fill out our online moving request form at least 10 days in advance to let us know when you are moving out.
Even if you are registered for e-billing or have made arrangements to forward your mail, we will require your new mailing address so we can arrange to send you your final bill or a cheque if you have a credit balance.
We cannot reactivate an old account at a new address. Each account number is unique.. The first 10 digits represent the customer or account holder and the last 10 digits represent the premise. The number can be found on your electricity bill and online account.
If you’re moving to a new address within Hydro Ottawa’s service territory, you will need to fill out our online moving request form at least 10 days in advance.
