Definitions and Explanations of Charges

Electricity Charges

Electricity use is billed in kilowatt hours (kWh), which is a measure of energy used over time. For example, if you use a 1,000 watt microwave for one hour, you used 1,000 watt-hours – or one kWh.

You pay for electricity based on when you use electricity in each of the three time-of-use periods: on-peak, mid-peak, and off-peak. Time-of-use rates are set twice each year by the Ontario Energy Board, on May 1 and November 1. Electricity charges are collected by Kitchener-Wilmot Hydro and paid directly to electricity suppliers. Kitchener-Wilmot Hydro does not keep any of these charges.

Time-of-use rates are based on provincial demand for electricity.

  • On-peak pricing is highest because that is when provincial demand for electricity is highest.
  • Off-peak pricing is lowest because that is when provincial demand for electricity is lowest.

Provincial "peak" electricity use changes in summer and winter.

  • In summer, provincial electricity use is typically highest in the middle of the day, when air conditioners are working hardest.
  • In winter, provincial electricity use is typically highest at the beginning of the day, when people and businesses are waking up and turning on lights, appliances, and machinery, and at the end of the day, when families return home and turn on lights and appliances for the evening.

Delivery Charges

Delivery is the cost of bringing electricity from generation stations to your home or business. Kitchener-Wilmot Hydro’s distribution charges are included in this portion of your bill.

Electricity Usage Adjustment Factor

  • An energy adjustment applied to the total amount of electricity used during the billing period to account for the line losses in the electricity system that are not measured by your meter. When electricity is delivered over a power line, it is normal for a small amount of power to be lost as heat. Line losses are an unavoidable part of delivering electricity. The adjustment factor is approved by the Ontario Energy Board and is reviewed regularly as part of the rate setting process.

Distribution Service Charge

  • This is a fixed or variable monthly charge that covers the costs associated with meter reading, billing, customer service, account maintenance, and general utility operations. 

Transmission Connection

  • The transmission connection charge covers the cost of connecting Kitchener-Wilmot Hydro’s distribution system to Hydro One’s transmission lines, as well as the cost of transforming electricity from high transmission voltages to lower voltages for distribution. This charge is applied against your total energy in kWh.

Transmission Network Charge

  • The transmission network charge covers the cost of delivering the electricity from the generating stations to the region through Hydro One’s transmission system. This charge is collected on behalf of Hydro One. This charge is applied against your total energy in kWh.

Smart Meter Entity

  • The charge paid to cover the cost of services provided by the Independent Electricity System Operator (IESO) for the implementation and operation of the province’s Meter Data Management/Repository, which stores, validates and manages hourly electricity information transmitted by smart meters.

Back to Delivery Charges

Energy Charges

Energy charges are made up of the sum of on-peak, mid-peak, and off-peak measured energy in kWh multiplied by the applicable time-of-use rate. Electricity charges are collected by Kitchener-Wilmot Hydro and paid directly to electricity suppliers. Kitchener-Wilmot Hydro does not keep any of these charges.

Back to top

Regulatory Charges

Regulatory charges include the cost of services required to operate the electricity system and run the wholesale electricity market. The Ontario Energy Board sets these charges.

Wholesale Market Service

  • The wholesale market service charge covers the cost of services provided by the IESO to operate the wholesale electricity market and maintain the reliability of the high voltage power grid and certain costs incurred by local utilities to connect renewable generation.

Standard Supply Administration Charge

  • The standard supply admininstration charge covers a portion of a utility’s administrative costs to provide electricity bills to customers that receive an invoice directly from the utility (i.e. customers that are not billed by a retailer). This charge is set by the Ontario Energy Board and is the same for all utilities across the province.

Global Adjustment

Global adjustment (GA) covers the cost of building new electricity infrastructure in the province, as well as delivering Ontario's conservation programs. It is calculated by the IESO and embedded in the time-of-use rates on your bill. If you have a contract with an energy retailer, you are billed global adjustment in addition to your energy costs. GA is calculated each month and is billed on your total kilowatt hour use. Learn more about how the GA is calculated
