- The Ontario Energy Board (OEB) sets the residential and small business rates for electricity under Ontario’s Regulated Price Plan (RPP). RPP rates are based on an estimate of how much it will cost to supply RPP customers with the electricity that they are expected to use. The OEB monitors and will adjust future RPP rates to reflect the difference between actual cost and their estimated cost. The next RPP rate adjustment is scheduled to take place on November 1, 2023. The majority of Hydro Ottawa’s residential customers are billed under the RPP.
- 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.
- 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.
- The Ontario government’s Ontario Electricity Rebate (OER) provides eligible consumers an 11.7% rebate on their electricity bill. The OER is a pre-tax credit that appears as a separate line on your Hydro Ottawa bill.
