Glossary of Terms


This is the cost of the electricity supplied to you during this billing period and is the part of the bill that is subject to competition.


These are the costs of delivering electricity from generating stations across the Province to Orangeville Hydro Limited then to your home or business. This includes the costs to build and maintain the transmission and distribution lines, towers and poles and operate provincial and local electricity systems. A portion of these charges is fixed and does not change from month to month. The rest are variable and increase or decrease depending on the amount of electricity that you use. The delivery charge also includes costs relating to electricity lost through distributing electricity to your home or business.** Orangeville Hydro Limited collects this money and pays this amount directly to our supplier. ** When electricity is delivered over a power line, it is normal for a small amount of power to be consumed or lost as heat. Equipment, such as wires and transformers, consumes power before it gets to your home or business.

Regulatory Charges

Regulatory charges are the costs of administering the wholesale electricity system and maintaining the reliability of the provincial grid.

Global Adjustment

Global Adjustment is a charge on a customer’s electricity bill that reflects the difference between the market price of electricity and the rates paid to regulated and contracted generators, and for demand management programs and conservation programs. The Global Adjustment charge fluctuates in relation to changes in the market price; when the market price for electricity is lower, the Global Adjustment is higher to cover additional costs that were not already received through the market price, and accordingly when the market price is higher the Global Adjustment is lower. Every Ontario electricity customer pays Global Adjustment. Customers who are on the Regulated Price Plan (RPP) have the charge built into the rate determined by the Ontario Energy Board. In contrast, customers who have a contract with a retailer and have therefore opted out of the RPP see the Global Adjustment on a separate line item on their bill. Customers with a peak demand higher than 50 kilowatts per month who also pay the market price see the Global Adjustment as a separate line item. Customers with a demand of above 5 MW (Class A Customers) are billed for Global Adjustment based on the percentage that their peak demand contributes to the top five Ontario system peaks. For example, if a Class A consumer is responsible for one per cent of Ontario’s peak demand for the five highest hours of the base period they will be charged for one percent of the total Global Adjustment costs. Orangeville Hydro collects the Global Adjustment funds for the IESO and transfers the funds to the IESO without taking a profit. The Global Adjustment is based on usage; by reducing usage, a customer can reduce the Global Adjustment charge on his or her bill. Global Adjustment significantly changes monthly. Therefore, some months the Global Adjustment will have more of an impact than others. Customers are advised to take an average of the monthly rates and budget their funds accordingly.

Ontario Fair Hydro Plan

In 2017, the provincial government introduced the Fair Hydro Plan which resulted in a 25 per cent reduction in electricity bills for Ontario’s residential customers and as many as half a million small businesses and farms, as compared to what they would have paid without the implementation of the Fair Hydro Plan.

  • January 1, 2017 – An eight per cent rebate equal to the provincial portion of the Harmonized Sales Tax on the bills of residential, farm, small business and other eligible customers was introduced by the Government of Ontario.
  • May 1, 2017 – The Ontario Energy Board reduced Time-of-Use electricity rates across the province and eliminated the Ontario Electricity Support Program charge that was a component of Regulatory Charges.
  • July 1, 2017 – The Ontario Energy Board further reduced Time-of-Use electricity rates across the province and lowered the Rural and Remote Rate Protection charge that is a component of Regulatory Charges.
  • As part of the Fair Hydro Plan, rate increases are being held to the rate of inflation for four years.
  • The Global Adjustment (GA) modifier is $44.38/MWh (or about 4.4¢/kWh). This credit is designed to provide eligible customers that are not paying Regulated Price Plan (RPP) prices with a level of benefit that corresponds with the benefit being provided to the proxy customer through the lower RPP prices. The GA modifier will be in effect from May 1, 2018 to April 30, 2019.
  • The province has expanded the Ontario Electricity Support Program, providing 50 per cent more support in the form of monthly credits for people with low incomes and increasing eligibility.
  • The province also established an Affordability Fund Trust for customers who do not qualify for low-income conservation programs and who are unable to undertake energy efficiency improvements without financial assistance.
  • The Industrial Conservation Initiative was expanded to include electricity consumers in the manufacturing and greenhouse sectors with an average monthly peak demand of greater than 500 kW and less than 1 MW.
