Tiered Pricing

Residential and small business customers who choose to be billed under the tiered pricing structure pay a set rate for the electricity they consume up to a kilowatt-hour (kWh) threshold per month. Customers that exceed this monthly threshold are billed at a higher rate per kWh for all additional electricity consumed.

Tiered prices give you the flexibility to use electricity at any time of day at the same price, although that price will change if you exceed the threshold during the month.

For residential customers, the threshold changes with the season to reflect changing usage patterns. In the winter period (November 1 – April 30), the tier threshold for residential customers is 1,000 kWh so that households can use more power at the lower price. In the summer period (May 1 – October 31), the Tier threshold for residential customers is 600 kWh.

Effective May 1 to October 31, 2023:

Tier 1

• Residential – first 600  kWh/month
• Non-residential – first 750 kWh/month
• 8.7¢/kWh

Tier 2

• Residential – for electricity used above 600 kWh/month
• Non-residential – for electricity used above 750 kWh/month
• 10.3¢/kWh

The Tier threshold for small business customers is 750 kWh all year round.

Effective November 1, 2022, small business consumers are charged:

• 8.7¢ per kWh for consumption up to 750 kWh/month

• 10.3¢ per kWh for consumption above 750 kWh/month

The Ontario Energy Board (OEB) determines the tiered rates at the same time as it sets the time-of-use (TOU) rates.

The OEB sets TOU and tiered prices based on its forecast of the cost to supply households and small businesses over the next 12 months. The next rate adjustment is scheduled to take place on November 1, 2023.

If you choose Tiered pricing, your electricity bill will include the costs for the electricity that you use (billed at Tiered rates) and other costs of delivering electricity.
