My Rates Explained

What goes into my Residential Tiered (RPP) bill?

There are two main factors used to calculate your electricity bill:
Your Price Plan

Customers that have not been switched over to Time-of-Use pricing will receive a bill that breaks down electricity usage by a set threshold. If you've noticed two different prices on your bills and slight changes between winter and summer seasons it's because you're on tiered pricing (also referred to as RPP or Regulated Pricing Plan). Two different prices are set on November 1st each year by the OEB: one price applies up to a certain threshold and a higher price applies if you go over this threshold.

For more information on Tiered prices and seasonal thresholds, visit our Electricity Prices page.

Your Rate Class

Your rate class (also known as service type) determines the rates that you pay for delivery. When assigning you to the proper rate class, we consider the nature and use of your electricity service, as well as the customer density in your area.

For a full explanation of the different service types and how Delivery rates are determined, visit our Rate Classes and Residential Delivery Rates pages.

Where does my electricity dollar go?

Although we bill you for the other line items on your bill, the money collected from your bill goes to several different corporations, regulators and independent generators that make up Ontario’s deregulated electricity market. This breakdown of where your electricity dollars go can be seen in more detail by visiting our Residential Rates and Charges page.

What does metered and adjusted usage mean?

Metered usage in kilowatt-hours is the amount of electricity you used in kilowatt-hours (kWh). It is calculated by taking the difference in meter readings and multiplied, if applicable, by the multiplier indicated on your meter.

Adjusted usage in kilowatt-hours is the amount of electricity you used in kWh adjusted to cover the line losses in the electricity system that are not measured by your meter. When electricity is transmitted over long distances and passes through wires and transformers, it’s normal for a small amount of power to be used or lost as heat. For example, if we deliver 1,000 kWh to you, we must purchase a small amount more than what you use. To determine the amount of electricity we need to buy for you, we use a calculation called an “adjustment factor.” The adjustment factor is approved by the Ontario Energy Board and varies according to your service type.
