The OEB set the new tiered rates for RPP customers effective May 1, 2021. These rates are explained in the following table:

These rates 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 (GA)

The GA 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 GA appears as a separate line on your bill. For more details, please visit the OEB website or the IESO website.

The Ontario government made two announcements related to the GA: the GA Reduction and GA Deferral Recovery effective January 1, 2021.

GA Reduction

As part of the Ontario budget, starting on January 1, 2021, the Ontario government is reducing the cost of the GA for industrial and commercial customers by shifting a portion of non-hydro renewable energy contract costs to the tax base. The GA Reduction is considerably larger than the GA Deferral Recovery. For more information, please visit the Government of Ontario website.

GA Deferral Recovery

The Ontario government announced that effective January 1, 2021 and for the next 12 months, non-RPP customers will repay the deferral GA costs from April to June 2020. To provide companies with temporary immediate relief on their electricity bills, the Ontario government deferred a portion of GA charges for industrial and commercial electricity consumers that did not participate in the Regulated Price Plan (RPP) from April until end of June 2020 by limiting the Class B GA rate to $115 per megawatt-hour and providing proportionate reductions for Class A customers. For GA Deferral rate information, please refer to the IESO website.

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 web page for more details.

The provincial government announced a decrease in the OER from 21.2% to 18.9%, effective May 1, 2021. The Ontario government introduced the OER as an expanded rebate providing bill relief that will be applied to customer bills, largely offsetting the price changes on the electricity line. The rebate will be applied to bills for most residential consumers, farms and many small businesses.

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.
