About Your Utility Bill

Knowing how to read your electrical bill is a good way to monitor your electricity and to see how conservation efforts can reduce your expenses.  To calculate your estimated bill on the OEB Website click here.

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 is the cost of the electricity supplied to you during a 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.


The delivery charge covers the costs of delivering electricity from generating stations across the province to your home or business through high voltage (transmission) and low voltage (distribution) power lines. It includes the costs to build and maintain transmission and distribution lines, towers and poles and to operate provincial and local electricity systems.

A portion of these charges are fixed and do not change from month to month. The rest are variable and increase or decrease depending on the amount of electricity that you use.

The delivery charge also includes the costs of the electricity lost when it is distributed. It is normal for a small amount of power to be lost as it travels over power lines.  Renfrew Hydro collects and pays this amount directly to our suppliers.

Regulatory Charges

Regulatory Charges are the costs of administering the wholesale electricity system and maintaining the reliability of the provincial grid.

The Smart Meter Entity charge recovers the costs of developing and implementing the Province’s central data repository that stores, processes and manages hourly electricity consumption data for smart meters. Renfrew Hydro collects this charge and passes it through without mark-up, to the Independent Electricity System Operator.

Ontario Electricity Rebate

Starting November 01, 2020, the Ontario government is providing a rebate on your electricity costs.  The Ontario Electricity Rebate will be 17% effective Nov 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.
