Common Charges

Whether you buy your electricity from Renfrew Hydro Inc. at a regulated rate or from an independent electricity retailer, your electricity bill each month contains a number of charges including:  


This charge relates to the energy that you used during the billing period.  This can either be provided by Renfrew Hydro Inc. or an electricity retailer.  Ontario residential and small business consumers that buy electricity from a utility are billed using either time-of-use rates or tiered rates.  The Ontario Energy Board sets both time-of-use rates and tiered rates.


This is the cost of delivering electricity from generating stations to your home or business. 


Delivery charges are approved by the Ontario Energy Board (OEB).  Some of these charges are "fixed," meaning you are charged the same amount no matter how much electricity is used.  Others are variable and increase or decrease depending on how much electricity you use.


Delivery charges include:

  • Customer Service Charge: A fixed charge for costs relating to meter reading, billing, customer service  and account maintenance, and general utility operations.

  • Distribution Charge: A variable charge for costs of building and maintaining the distribution system, including  overhead and underground power lines, poles, and transformer stations.  Click here to view all utility electricity distribution rate applications and decisions.

  • Transmission Charge: A variable charge for the costs of transmitters to operate and maintain the high-voltage transmission system that carries electricity from generating stations to your utility.

  • Line Loss Adjustment:  When electricity is delivered over a power line, it is normal for a small amount of power to be consumed, or lost.  In calculating your electricity costs for the billing period, we multiply your electricity cost by an OEB approved adjustment factor that accounts for those losses.

Regulatory Charges

This charge is made up of the following components:


Wholesale Market Service Charge: This charge covers the cost of services provided by the Independent Electricity System Operator (IESO) to operate the wholesale electricity market where electricity is bought and sold and maintain the reliability of the high voltage power grid.  This charge also includes a per kWh charge for Rural and Remote Rate Protection, which all customers pay to offset the higher cost to distribute electricity to consumers in rural and remote areas.


Standard Supply Service Charge: This charge covers administrative costs incurred to provide electricity to Standard Supply Service customers - consumers who purchase electricity from a utility instead of from a licensed electricity retailer.  This charge is the same for all utilities in the province.

Ontario Electricity Rebate

Starting November 01, 2020, the Ontario government is providing a rebate on your electricity costs.  The Ontario Electricity Rebate will be 18.9% effective May 1, 2021.

Global Adjustment

Most electricity generating companies get a guaranteed price for electricity that they produce.  The Global Adjustment is the difference between that guaranteed price and the money the generators earn in the wholesale market.  All electricity consumers have to pay a share of the Global Adjustment.  If you buy electricity under the Regulated Price Plan, an estimate of the Global Adjustment amount is reflected in the stable price for electricity set by the OEB, shown on the "Electricity" line of your bill.  If you buy from an electricity retailer, the Global Adjustment is not included in the contract price offered by the electricity retailer; therefore, it will appear as a separate line item on your bill.
