Tiered Pricing is broken down into set amounts of electricity that may be used at a specific rate; once this set amount is exceeded, the rate changes to a more expensive tier. Tiered pricing is generally updated annually on May 1 and November 1. 

As of May 1, 2024 - October 31, 2024, Tiered prices for residential customers are:

First Tier - Up to 600 kWh

Second Tier - More Than 600 kWh

10.3 cents per kWh

12.5 cents per kWh

Tiered prices for non-residential customers are:

First Tier - Up to 750 kWh

Second Tier - More Than 750 kWh

10.3 cents per kWh12.5 cents per kWh

***In calculating your bill, your consumption amount will be adjusted to account for heat loss. When electricity is delivered over a power line, it is normal for a small amount of power to be consumed or lost as heat. Equipment such as wires and transformers consume power before it gets to your home or business. The adjustment factor accounts for these losses.


****Adjustment Factor Charge is kWh x 0.0288 x Electricity Rate. For Example: 200 kWh x 0.0288 Adjustment Factor x Electricity Rate = 5.76 kWh x $0.151/kWh = $0.8697.

***** Monthly Administration charge applies to non-retailer affiliated customers only.

About TOU Pricing

With TOU prices, the price depends on when you use electricity. You can help manage your electricity costs by shifting your usage to lower price periods when possible.

There are three TOU periods:

  • Off-peak: When demand for electricity is lowest. Ontario households use most of their electricity – nearly two thirds of it – during off-peak hours.
  • Mid-peak: When demand for electricity is moderate. These periods are during the daytime, but not the busiest times of day.
  • On-peak: When demand for electricity is generally higher. These are the busier times of day - generally when people are cooking, starting up their computers and running heaters or air conditioners.

People use electricity differently depending on the season, so the TOU price periods are different in the winter than they are in the summer.

About Ultra Low Pricing

Like TOU, ULO prices depend on when you use electricity. This price plan is ideal for those who can shift a significant amount of their usage to overnight.

There are four ULO price periods:

  • Ultra-Low Overnight, when demand for electricity is lowest on average.
  • Weekend Off-peak, when demand for electricity is generally lower.
  • Mid-peak, when demand for electricity is moderate.
  • On-peak, when demand for electricity is highest on average.

The ULO price periods are the same in the summer as they are in the winter. On weekends and holidays the cheapest rates are in effect all day. View the Holiday Schedule for Time-of-Use and Ultra-Low Overnight.

About Tiered Pricing

With Tiered prices, you can use a certain amount of electricity each month at a lower price. Once that limit (called a threshold) is exceeded, a higher price applies. For residential customers, the threshold normally changes with the season to reflect changing usage patterns – for example, there are fewer hours of daylight in the winter and some customers use electric heating.

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. 

For small business customers, the Tier threshold is 750 kWh all year round. 

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.
