Understand My Bill
Coming soon: Updates to this page will be available by early November 2025.
Instructions: Click on any grey highlighted portion of the sample Net Metering Time-of-Use bill pages for more details about that specific section or line item. Switch between pages 1, 2 or 3 of the sample bill using the underlined links below.
Your 12-digit account number is located in the top right hand corner on your statement. You’ll need to use this number when making payments, when you contact us for customer service or to report an outage. If you move to another property serviced by us, you’ll continue to use the same account number.
This is the date your statement was issued. You have 19 days to pay your statement before you incur late payment charges on outstanding balances.
This indicates the start and end date for your electricity usage captured for billing purposes. You can tell the length of your billing period by reviewing the number of days shown in brackets under the “current month” in the “What does my electricity usage look like?” graph.
Please pay the total amount owing, which includes the current statement amount plus any outstanding balance from previous statements. Please turn over your statement for a summary of how we calculated your charges.
This shows how much electricity you have used in kilowatt-hours (kWh) over the billing period. To see your current and previous meter readings, along with the dates obtained, please turn over your statement. This information is displayed below your itemized charges.
Please pay your statement by the due date to avoid any late payment charges. Click here to find the easy ways you can pay your statement.
If you’ve signed up for AutoPay (Pre-Authorized Payments) it will show the date your payment will be withdrawn from your bank account.
This graph shows how much electricity you’ve used for the current billing period and compares it to your previous billing period and the same period last year. To help you understand any variations in your usage, we’ve included the number of days for each period shown.
To find more details about your electricity usage, please log in to myAccount to access these tools. If you’re a first time user, you’ll need a copy of your electricity statement to register. Once you’ve logged on to myAccount, select "My Energy Usage" to see how much electricity you’ve used on an hourly, daily or monthly basis. You can also compare your statements and use the "Predict my Bill" tool to estimate the amount of your next statement.
Remember to check this section for important information that might affect your statement.

If you’ve enrolled with an electricity retailer, this is the number you should use when you call them.
When assigning your service type (also known as rate class), we consider the nature and use of your electricity service, as well as the number of other customers connected to the distribution line. The more customers there are in your area, the lower the cost to serve you. Knowing your service type will help you identify which delivery rates apply to you. There are three different service types for year-round residential customers, which are based on customer density: Urban Density, Medium Density and Low Density. The residential seasonal service type is defined as any residential service not meeting the year-round criteria. It includes dwellings such as cottages, chalets and camps. To learn more, please visit our service types webpage.
We break down your electricity charges by line item and provide an explanation for each.
Next to the Electricity line item is a breakdown of your energy use on Tiered prices. The Ontario Energy Board sets Tiered prices and thresholds. At a glance, you can see how much electricity your small business has used in each of the two threshold periods: Tier 1 usage up to 750 kWh, and Tier 2 usage above 750 kWh. We have included a graph so you can see the year-round Tiered schedule.

Did you know you can sign up for high usage alerts through myAccount? If you’re trending to use more than 30% more electricity compared to the same period last year, we’ll let you know. The alert will arrive between the 7th and 21st day after you received your prior statement. Click here to learn more and sign up.
This is the cost of the electricity that you used during the billing period. For residential and small business customers who are on the Regulated Price Plan, there are three price plans: Time-of-Use (TOU), Ultra-Low Overnight (ULO) and Tiered. The Ontario Energy Board sets prices for these price plans once a year on November 1. The money we collect for electricity goes directly to the electricity generators without any markup.
This is the cost of ensuring you have reliable power when you need it. Hydro One collects this money to build, maintain and operate the electricity infrastructure, which includes power lines, steel towers and wood poles covering over 960,000 sq. km. A portion of this cost is fixed and a portion varies depending on the amount of electricity used.

The Regulatory charge reflects the cost of administering the wholesale electricity system and maintaining the reliability of the provincial grid to ensure there is enough electricity to meet Ontario’s needs. Hydro One doesn’t charge a markup on this cost. It is paid directly to the Independent Electricity System Operator (IESO).
HST (Harmonized Sales Tax) is 13 per cent.
The Ontario Electricity Rebate reduces the pre-tax amount of the bill by 19.3%, effective November 1, 2023.
The rebate is calculated on the base amount of the bill prior to applying HST. The base amount includes the Electricity charge, Delivery charge, and Regulatory charges. It excludes any other charges that may appear on bills such as late payment charges or disconnection charges.
If your first bill issued after November 1, 2023 includes any usage in September or October, the rebate will be pro-rated based on the number of days of usage pre-November at 11.7% and the number of days of usage on and after November 1, 2023 at 19.3%.
This section displays if you have any generation credits or charges such as a late payment charge, account set up charge, etc. Please refer to “Electricity charges for billing period” shown on page 3 to see the breakdown of your generation credits.
Your meter number is the number shown on your electricity meter. Your meter may be located on an outside wall, inside your home or mounted on a pole. If you live in an apartment or condominium, your meter is probably centrally located with the meters of other units.
Your meter reading period indicates the start and end date of when your electricity usage in kilowatt-hours (kWh) was captured for billing purposes. If your meter reading is estimated, it will show “Estimate” next to your readings. If there is no “Estimate” shown, your readings are based on an actual read.
Your usage in kWh represents your total consumption during your meter reading period.
