Types of electricity rates

Time-of-Use (TOU)

TOU rates work together with your smart meter. With TOU rates, you pay according to the time of day you use electricity. So it's important to manage how much electricity you use and when you use it.

The OEB has announced new electricity prices in effect for your consumption between May 1, 2019 and October 31, 2019.

Summer pricing period, effective May 1, 2019 to October 31, 2019

TOU period Hours Price
On-Peak Weekdays from 11 a.m. to 5 p.m. 13.4¢ per kWh
Mid-Peak Weekdays from 7 a.m. to 11 a.m. and 5 p.m. to 7 p.m. 9.4¢ per kWh
Off-Peak Weekdays from 7 p.m. to 7 a.m. and all day weekends and holidays 6.5¢ per kWh

The rates quoted above cover the cost of electricity purchased on your behalf. Toronto Hydro passes this cost through to you, without mark-up, and pays it directly to our suppliers.

If you are on Regulated Price Plan Tiered Pricing, your consumption in kWhs is separated into two price tiers under the government's Regulated Price Plan. You will be charged one rate for the first 750 kWhs of usage per 30 days. Any electricity that you consume over this 750 kWh threshold will be priced at a higher rate. For more information, please visit the Ontario Energy Board's website.

Tiered rates pricing - per 30 days

Price tier Description Price
Tier 1 Non-residential customers: for electricity used up to 750 kWh/month 7.7¢ per kWh
Tier 2 Non-residential customers: for electricity used above 750 kWh/month 8.9¢ per kWh

The rates quoted above cover the cost of electricity purchased on your behalf. Toronto Hydro passes this cost through to you, without mark-up, and pays it directly to our suppliers.

Most General Service customers with monthly demand greater than 50 kW, who do not have a contract with a retailer, pay the wholesale electricity price and Global Adjustment electricity charge. Toronto Hydro collects both charges, without mark-up, on behalf of the Independent Electricity System Operator (IESO).

Customers with interval meters are charged the Hourly Ontario Energy Price (HOEP), which is the hourly price that is charged to Toronto Hydro, for their electricity consumption. Customers without interval meters are charged a weighted average hourly price based on consumption patterns of similar consumers. Customers may also choose a contract offered by a licensed electricity retailer.

Global Adjustment

Global Adjustment accounts for the differences between the market price of electricity and the rates paid to regulated and contracted generators for the electricity they produce. It also reflects the costs of conservation and demand management programs by both the IESO and Toronto Hydro. As a result, its value may be negative, depending on the fluctuation of prices in the spot market.

For medium and large businesses the Global Adjustment appears as a separate line on your bill. Please visit the OEB or the IESO for more details.

Under the Fair Hydro Act, 2017, if you are eligible for the 8% Provincial Rebate, you will share the benefit of reduced electricity bill as those customers under the Regulated Price Plan (RPP). Effective May 1, 2019, the Ontario Energy Board has set a credit of $41.49 per MWh, which will be incorporated into the Global Adjustment (GA) charge to reduce the amount of GA you would otherwise have paid. Toronto Hydro will apply this credit to your consumption on or after May 1, 2019 through to October 31, 2019.

Retailer Rates

You may choose to purchase your electricity by entering a contract with a licensed electricity retailer. The contract specifies a fixed electricity price for a set number of years. Unlike Toronto Hydro's rates, the fixed price is not regulated by the Ontario Energy Board (OEB). Please visit the OEB's Retail Energy Contracts website for more details.

Under the Fair Hydro Act, 2017, customers who are not billed on the Regulated Price Plan (RPP) but are otherwise eligible for the 8% Provincial Rebate, will share the benefit of reduced electricity bill as those customers under the Regulated Price Plan. Effective May 1, 2019, the Ontario Energy Board has set a credit of $41.49 per MWh, which will be incorporated into the Global Adjustment (GA) charge to reduce the amount of GA you would otherwise have paid. Toronto Hydro will apply this credit to your consumption on or after May 1, 2019 through to October 31, 2019.

On January 1, 2017, your electricity costs went down 8%.

Ontario’s government is reducing electricity costs by rebating an amount equal to the provincial portion of the HST on your monthly hydro bill. That’s an 8% rebate for Ontario families, and on average will mean $130 more in your pocket each year. This is part of Ontario’s plan to help people with the costs of everyday living by reducing electricity costs. Across Ontario, about five million residential consumers, farms and small businesses will benefit from this rebate. Toronto Hydro has implemented these savings onto your bill on January 1, 2017.

For additional information on the 8% Provincial Rebate, please visit the Ministry of Energy.

Effective July 1, 2010, Harmonized Sales Tax (HST) of 13% is applied to electricity bills. The implementation of HST is mandated by the Province of Ontario. For information on HST, please visit the Ontario Ministry of Revenue or call the HST hotline at 1-800-337-7222.

These charges are applied to current customers who have an unmetered electric water heater billed by Toronto Hydro on a flat rate basis. Toronto Hydro no longer offers this flat rate billing option for new customers.

As of May 1, 2002, flat rate (unmetered) water heater energy usage is billed on an estimated average daily kWh basis. Your estimated usage is determined by the size of your water heater, the wattage of the water heater electric elements and on the number of days in the billing period. If you have an unmetered electric water heater, you’re being billed on the higher tiered rate of the Regulated Price Plan.
