Commercial Electricity Rates

Residential and small business customers can choose between a Time-of-Use (TOU), Ultra Low Overnight (ULO), or Tiered pricing structure.

There are three options: Time-of-Use (TOU), Ultra Low Overnight (ULO), and Tiered.

With TOU and ULO pricing, you can help manage your electricity costs by shifting your usage to lower off-peak periods when possible. The price you pay for electricity depends on when you use it. Under Tiered pricing, you can use a certain amount of electricity each month at a lower price, and one that limit is exceeded, a higher price applies.

For more information on Time-of-Use, Ultra Low Overnight, and Tiered pricing, and tools to help you decide which price structure is right for you, please visit. www.oeb.ca/choice.

Tiered Thresholds Price

A small number of customers are on the pricing system, known as Tiered Thresholds pricing. The charges for these customers, effective May 1, 2025 - October 31, 2025 are:

Up to 750 kWh/per month	¢/kWh	9.3
Consumption beyond 750 kWh/per month	¢/kWh	11.0

General Service customers with consumption in excess of 250,000 kWh are subject to hourly electricity pricing. Customers with an interval meter pays the hourly spot price; customers who do not have an interval meter pay the weighted wholesale price. In addition, a customer on hourly electricity pricing has a separate line item on their bill called global adjustment.
