Other Charges

Learn about some of the additional rates and charges that may appear on your bill.


1. The Debt Retirement Charge (DRC) will no longer apply or appear as a line item on customer bills for consumption after March 31, 2018. Bills which include electricity consumption prior to April 1, 2018 will include a DRC line item for the applicable amount.

2. Customers with a monthly billing demand of 50 kW or more should refer to our Business Rates brochure for more information.

3. The Ontario Energy Board (OEB) sets the residential and small business rates for electricity under Ontario’s Regulated Price Plan or RPP. The OEB reviews and adjusts these rates, if required, twice a year: in the summer (May 1) and in the winter (November 1).

4. The Delivery Line Loss Charge is calculated by multiplying the Electricity Charge Consumption (per RPP Category) by the loss factor and then multiplying this number by the current month’s Electricity Charge under the RPP rate.

5. For customers who do not purchase their electricity from an electricity retailer, a monthly administration fee of $0.25 is added to the Regulatory Charge to recover a portion of the cost of systems required for the market. Class A customers are charged the Capacity Based Recovery (CBR) based on their peak demand factor (PDF). The CBR is part of the Regulatory line and is a rate of $0.0004/kWh.  Class A Customers Regulatory rate without CBR is $0.0053/kWh.

6. The rebate will be equal to the provincial portion of the Harmonized Sales Tax (HST) on electricity bills, representing an 8% savings.

7. Wholesale Market Participants (WMP) purchase electricity through the Independent Electricity System Operator (IESO). As a result, specific rates do not apply to WMP as they settled directly with the IESO. Within Hydro Ottawa Variable and Other Charges, WMP are not charged the Rate Rider for Disposition of Deferral/Variance Accounts - effective until December 31, 2018 applicable only for Non-WMP. The following are the rates by class of Customer within Hydro Ottawa Variable and Other Charges that do not apply to WMP; 50 kW to less than 1,500 kW Billing Demand -$0.3381/kW; 1,500 kW to less than 5,000 kW Billing Demand -$0.3761)/kW; 5,000 kW or more Billing Demand (Large Consumer) -$0.4451/kW. These rates would be subtracted from the rate posted for Hydro Ottawa Variable and Other Charges. Please note for 2018 these rates are in the form of a credit and would therefore increase the rate.

8. The rate rider for the disposition of Global Adjustment is only applicable to non-RPP Class B customers. It is not applicable to  WMP customers that transitioned between Class A and Class B during the variance account accumulation period, or to customers that were in Class A for the entire period. Customers who transitioned are to be charged or refunded their share of the variance disposed through customer specific billing adjustments. This rate rider is to be consistently applied for the entire period to the sunset date of the rate rider. In addition, this rate rider is applicable to all new non-RPP Class B customers.
