Business rates and charges

Understanding current rates and how they're set.

Rates as of May 1, 2023

Effective May 1, 2023, the Ontario Energy Board (OEB) has introduced a new Ultra-Low Overnight (ULO) price plan for Regulated Price Plan (RPP) customers. ULO offers customers rates based on ultra-low overnight, mid-peak, on-peak and weekend off-peak pricing. This may benefit customers who shift high electricity-usage activities, such as charging electric vehicles, to lower-demand periods overnight. ULO price periods are the same in the summer as they are in the winter.

In addition, May 1 marks the change to summer hours for Time-of-Use customers and tier thresholds for Tiered customers.

Summer Tiered pricing from May 1, 2023 to October 31, 2023

Price tierDescriptionPrice
Tier 1Non-residential customers: for electricity used up to 750 kWh/month8.7¢ per kWh

Most General Service customers with a monthly demand greater than 50 kW – who don’t have a contract with a retailer – pay the wholesale electricity price and Global Adjustment electricity charge. Toronto Hydro collects both charges from you, 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’s 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.

You may choose to purchase your electricity from another company by entering a contract with a licensed electricity retailer. Your 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 OEB. Please visit the OEB's Retail Energy Contracts page for more details.

Delivery Charges

Toronto Hydro received approval from the OEB to implement changes to its Delivery Charges, effective January 1, 2023.

Delivery Charges cover the cost of delivering electricity from the generator to Toronto Hydro, and then to your home or business. This includes costs to build and maintain transmission and distribution lines, towers and poles, and to operate provincial and local electricity systems.

Regulatory charges

The OEB announced an update to Regulatory Charges, effective January 1, 2023.

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

Refer to the following table for current charges. For an explanation of the charge, please refer to the list of terms and definitions at the bottom of the page.

Regulatory charges

Charge nameRate
Capacity-Based Recovery (applicable for Class B customers)$0.0004 per kWh
Standard Supply Service – Administration (if applicable)$0.25 per 30 days

Additional charges

Effective July 1, 2010, a 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.

The provincial government announced a decrease in the OER from 17% to 11.7%, effective November 1, 2022. The Ontario government introduced the OER as an expanded rebate providing bill relief that will be applied to customer bills, largely offsetting price changes on the electricity line. The rebate will be applied to bills for most residential consumers, long-term care homes, farms and many small businesses.

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 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.

If you have any questions, please visit our contact page to reach us by phone or using our online contact form.
