Example Hydro Bill Image

1. Usage

The amount of electricity (kWh) or water (cubic metres) you used during the billing period.

2. Adjustment Factor

When electricity is delivered over a power line, it is normal for a small amount of power to be consumed or lost as heat before it gets to you. As a result, THI needs to buy slightly more electricity for its customers than is reflected in meter readings. The cost of this additional energy is recouped through the adjustment factor.

We calculate the adjustment factor by comparing the total amount of electricity we buy on behalf of all our customers to the amount of electricity actually delivered to their homes and businesses. Adjustment factors are reviewed and approved by the Ontario Energy Board and will vary according to your service type.

3. Adjusted Amount

This section shows the true amount of electricity required for your property. Usage x Adjustment Factor = Adjusted Amount.

4. Electricity Charges

This section shows you how much energy was used in each time-of-use rate category. Remember, the less electricity you require during peak hours, the lower your costs will be. (If you purchase your Hydro from a 3rd party your bill may look different in this area)

5. Delivery Charges

These are the costs of delivering electricity from the generating stations across Ontario to Tillsonburg Hydro Inc., and then to your home or business. The charges in this section help to offset the costs of building and maintaining the electrical infrastructure (transmission and distribution lines, towers, poles etc.) as well as operating the provincial and local electricity systems. A portion of this amount is fixed and does not change from month to month. The remainder is variable and will increase or decrease depending on the amount of energy you use.

6. Regulatory Charges

This section accounts for the cost of administering the wholesale electricity system and maintaining the provincial grid.

7. Debt Retirement Charge

The amount you pay toward the Debt Retirement helps pay off the remaining debt from the former Ontario Hydro. The Debt Retirement Charge is calculated based on the amount of electricity you use - so it may vary from one bill to the next. To find out more about the Debt Retirement Charge visit the Ontario Electricity Financial Corporation (OEFC)'s website.

8. Ontario Clean Energy Benefit

The Ontario Clean Energy Benefit provides you with a 10% rebate on your total bill every month up to 3,000 kWh per month, which means most residential customers are covered. Farms and small businesses can also enjoy the 10% rebate off their bill up to 3,000 kWh per month. This is a credit from the Ontario Energy Board to help offset the cost of moving our province to a cleaner, more modern electrical grid.
