Your service address

This shows the property that’s being billed.

Your Point of Delivery number

If you’ve enrolled with an electricity retailer, this is the number you should use when you call them.

Your service type

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 High, 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.

Ultra-Low Overnight Electricity Prices

Next to the Electricity line item is a breakdown of your energy use on Ultra-Low Overnight (ULO) prices. The Ontario Energy Board sets electricity prices once a year on November 1. At a glance, you can see how much electricity you have used in each of the four ULO demand periods: on-peak, mid-peak, weekend off-peak, and ultra-low overnight. We have included a graph so you can see the ULO weekday schedule. Remember, weekends and holidays are always off-peak until 11 PM, then ultra-low until 7 AM.

Electricity

This represents the cost of the electricity you used during the billing period. We measure your usage in kilowatt-hours (kWh), which is determined by the power consumption of your appliances and devices, and how long you use them. The Ontario Energy Board (OEB) establishes the rate per kWh. It's important to note that the full amount you pay for electricity generation goes directly to the power producers without any additional charges from us.

Delivery

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.

Regulatory

The Independent Electricity System Operator (IESO) uses this money to manage electricity supply and demand in the province, which is necessary to ensure that there is enough electricity to meet Ontario’s needs all the times.

HST

HST (Harmonized Sales Tax) is 13 per cent.

Ontario Electricity Rebate

The Ontario Electricity Rebate reduces the pre-tax amount of the bill by 13.1%, effective November 1, 2024.

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, 2024 includes any usage in September or October, the rebate will be pro-rated based on the number of days of usage pre-November at 19.3% and the number of days of usage on and after November 1, 2024 at 13.1%.

Your Adjustments

This section is displayed if you have any credits or charges, such as a late payment charge, account set up charge, etc.

Meter Reading Period

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.
