Ontario Electricity Rebate


Other Charges

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

  1. The Ontario Energy Board (OEB) sets the residential and small business rates for electricity under Ontario’s Regulated Price Plan (RPP). The OEB reviews and adjusts these rates, if required, twice a year: in the summer (May 1) and in the winter (November 1). The majority of Hydro Ottawa’s residential customers pay Time-of-Use rates. If you are a Tiered price customer, please visit for more information.
  2. 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.
  3. 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.
  4. The Ontario Electricity Rebate (ORE) applies to customers’ bills effective November 1, 2019 and reduces the pre-HST amount of the bill. The ORE largely replaces the Fair Hydro Plan adjustments to the price of electricity.
