Business / Commercial Rates

In Ontario, electricity rates are set by the Ontario Energy Board (OEB). Your bill includes charges for the electricity commodity (generation), transmission through high voltage systems (e.g. Hydro One), and distribution through local systems (e.g. ENWIN). The OEB must ensure that all rates are justified and reasonable. ENWIN is required to prove to the OEB that its rates are justified and reasonable through a rate application process. The current OEB-approved rates are listed below. More information on rates is available at the OEB website.

*Charge is per connection 
 
Note: Non-RPP, Class B customers will also have the Rate Rider for Global Adjustment Account Disposition of $-0.0016 / kWh. 

Large Use - Regular and Dedicated Transformer Station rates are available upon request. 

Applies to those customers meeting the legislative criteria (residential/low-volume consumer) of the program. A regulated price per kWh is charged for electricity used. 

Time-of-Use Pricing effective November 1, 2024 - October 31, 2025 

Ultra-Low Overnight Pricing effective November 1, 2024 - October 31, 2025

Under tiered rates, a customer can use a certain amount of energy each month at a lower rate. Once that limit is exceeded, the rate goes up. The chart below shows the rates and tiers for each type of customer. 

Tiered Pricing effective November 1, 2024 - October 31, 2025 

**All kWh thresholds for tiered pricing are based on a 30 day billing period.  Billing periods shorter or longer than 30 days will decrease or increase the threshold proportionally.  For example, a 33 day billing period will result in a 10% higher threshold amount (33/30 = 110%). 

The electricity price you pay per kWh is: 

1. The spot market price or weighted average price (dependant on the type of meter installed), or 

2. A retailer contract price (dependent on your choice of electricity provider). 

You will also be subject to a separate charge for the Global Adjustment, which will appear as a separate line item on your bill.  More information is available here: Class B Global Adjustment and Class A Global Adjustment. 

The Ontario Electricity Rebate (OER) is for most households, farms, long-term care homes and small businesses.  Starting November 1, 2024, the OER will provide eligible consumers with a 13.1% rebate from the province on the subtotal of their electricity bill. 

Consumers with demand of 50 kilowatts or less or annual consumption of 250,000 kilowatt hours or less, farms, and licensed long-term care homes (other than where the electricity account is also in respect of a hospital) are eligible to receive the rebate.   

Some multi-unit residential complexes that do not have individually metered units may also be eligible with demand above 50 kilowatts and annual consumption above 250,000 kilowatt hours.   

Starting July 1, 2022, the following types of consumer accounts will also become eligible for the OER: 

• Common areas in residential multi-unit complexes such as condominium buildings; 

• Retirement residences; and 

• Mobile home parks

*Applies to customers not contracted with an energy retailer. 

As electricity is delivered over a power line, a small amount of power is consumed or lost as heat. This is known as line loss, and is caused by wires and transformers that consume power before it gets to your home or business. The loss factor adjustment accounts for these losses. 

A Late Payment Charge of 1.5% per month (compounded to 19.56% annually) will be applied to any past due balance.
