Electricity Rate Selection

Power is Personal. For residential and small business customers that buy electricity from their utility, there are two different types of rates (also called prices). The Ontario Energy Board sets both TOU and Tiered Rates. Read more below how the two rate structures differ.

Tiered Rates

With Tiered prices, customers can use a certain amount of electricity each month at a lower price. Once that limit (called a threshold) is exceeded, a higher price applies to the incremental consumption above the threshold. Although May to Feb 2021 has been an exception due to COVID-19, for residential customers, the threshold normally changes with the season to reflect changing usage patterns. For example, there are fewer hours of daylight in the winter and some customers use electric heating. In the winter period (November 1 – April 30), the Tier threshold for residential customers is 1,000 kWh, so that households can use more power at the lower price. In the summer period (May 1 – October 31), the Tier threshold for residential customers is 600 kWh. The Tier threshold for small business customers is 750 kWh all year-round.

Time-of-Use Rates (TOU) 

On November 1, 2020, new Time-of-Use (TOU) and Tiered prices came into effect under the Ontario Energy Board’s (OEB) Regulated Price Plan (RPP). Although May to October 2020 was an exception due to COVID-19, TOU price periods are normally different in the winter (November 1 to April 30) than they are in the summer (May 1 to October 31) as people use electricity differently depending on the season.

Choosing an Electricity Plan that’s Right for You

  • For customers that have signed up for a contract with an energy retailer, the price is set out in the contract. The Ontario Energy Board does not regulate this. Read more about contracts.
  • The choice between TOU and Tiered prices is available to nearly all residential and small business customers that have smart meters and are billed on TOU. Some residential and small business customers are charged Tiered prices because their meters can’t be used to bill TOU prices. They can’t switch to TOU prices at this time.
  • If you live in a condominium or apartment that has its own individual meter and your bill comes from a company other than Greater Sudbury Hydro, you are a customer of a unit sub-meter provider (USMP). Customers of USMPs also can’t switch to Tiered prices. That decision can only be made for the building as a whole by the “master consumer,” who is the person that retained a USMP for the property. In most cases, the master consumer is the property manager, landlord or condominium board.
  • Customers that are buying their electricity from an energy retailer pay the electricity price set out in their contract. Once they have left their retail contract, they will have a choice between paying TOU or Tiered prices. For details about your energy contract, contact your energy retailer.

Where a Dollar Went in 2019

This illustration shows how each dollar paid on a Greater Sudbury Hydro bill in 2019 was distributed. Note that only 16.6 cents of each dollar stayed in Sudbury. The rest was passed through to other agencies.


PAID TO IESO, Hydro One & Electricity Generators


GSH retains only 16.5%. Other agencies absorb the remaining 83.5%.


Paid to Provincial and Federal governments.


Paid to Hydro One


Paid to IESO and Ontario Electricity Finance Corporation.

Greater Sudbury Hydro controls only the “distribution rate”, which is part of the “delivery charge” line of your bill. The rest of the charges are collected by GSH on behalf of other agencies, but they flow through and do not remain with Greater Sudbury Hydro.
