Electricity Rates

The cost for the electricity you used during the billing period.

• Higher volume consumers (medium and larger businesses) who buy their electricity from Waterloo North Hydro pay hourly or weighted average market prices. Market prices are set hourly by the Independent Electricity System Operator. You will also have to pay your share of the Global Adjustment for each month.
• Customers who have signed an retail contract with an electricity retailer will pay a contract rate. Retail contracts are often for a fixed price over a set number of years. You will also have to pay your share of the Global Adjustment for each month.
• Rates
  • Accounts with interval type meters (records hourly consumption) pay a market hourly rate + or *. (HOEP). Visit IESO web site at www.ieso.ca for current and historical hourly (HOEP) rates
  • Accounts without interval meters pay a weighted average market rate+. Contact Waterloo North Hydro for details.

Delivery Charges

The cost of delivering electricity from generating stations across the Province to your home or business via the high voltage (transmission) and low voltage (distribution) electricity systems. All the charges on this line of the bill are approved by the ONTARIO ENERGY BOARD. Some of the charges are fixed at a set amount per month. Others are variable and increase or decrease depending on the amount of electricity you have used. View a breakdown of Delivery Charges.

Please note new delivery rates effective January 1, 2018. For previous rates please see our .Historical Rate Cards

Regulatory Charges

This charge includes:

• Wholesale Market Service Charge: A charge to cover the cost of services provided by the Independent Electricity System Operator (IESO) to operate the wholesale electricity market and maintain the reliability of the high voltage power grid. It also covers the administration costs of the Ontario Power Authority (OPA) and certain costs incurred by Waterloo North Hydro to connect renewable generation. The Wholesale Market Service Charge is set by the ONTARIO ENERGY BOARD to allow these costs to be passed on to consumers.
• Standard Supply Service - Administration Charge: A charge to cover a portion of Waterloo North Hydro's administrative costs to provide electricity to Standard Service Supply customers that purchase their electricity from the utility (i.e. customers that are not served by a retailer). This charge is set by the ONTARIO ENERGY BOARD and is the same for all utilities across the province.

* A line loss adjustment factor of 1.0362 is applied to these charges.

Debt Retirement Charge (DRC)

The Debt Retirement Charge has been removed from bills effective April 1, 2018. The Debt Retirement Charge was $0.007 per kWh.

Global Adjustment

If you purchase electricity from a retailer or based on market pricing, you will see a separate line item on your bill for the "Global Adjustment". The Global Adjustment accounts for differences between the market price of electricity and the regulated or contract prices paid to generators for the electricity they produce. These include nuclear, gas-fired and renewable generators (like wind farms) that have contracts with the Ontario Power Authority (OPA) and generators that have contracts with the Ontario Electricity Financial Corporation (OEFC), as well as Ontario Power Generation's "baseload" generating stations that operate at or near capacity all the time to meet basic demand. The ONTARIO ENERGY BOARD does not set or approve the amounts paid by the OPA or OEFC to contracted generators, but it does set the amounts that are paid to Ontario Power Generation for electricity generated by its baseload facilities.

The Global Adjustment also includes the cost of OPA conservation and demand management programs. Those costs are not subject to ONTARIO ENERGY BOARD approval. Also covered by the Global Adjustment are any ONTARIO ENERGY BOARD-approved costs incurred by utilities to achieve their mandatory conservation and demand reduction targets.

The Global Adjustment is calculated monthly by the IESO. Because a large portion of the Global Adjustment is calculated as the difference between the market price and regulated or contracted generation prices, it can be either a credit or a charge to consumers depending on fluctuations in the market price. However, it has been a charge since 2006. Visit IESO web site at www.ieso.ca for current and historical rates +
