With TOU or ULO pricing you’ll receive a different price based on time of day (off-peak, mid-peak, on-peak, or overnight), while with Tiered pricing, you can use a certain amount of electricity each month at a lower price. Once that limit or threshold is exceeded, a higher price applies.
The prices that apply to each of these plans are set once a year by the Ontario Energy Board on November 1, and we pass these prices to you without any markup.
Time-of-Use (TOU) or Ultra-Low Overnight (ULO)
With TOU or ULO price plans, you can help manage your electricity costs by shifting your usage to lower price periods when possible, as the price depends on when you use electricity:
-
Overnight (ULO only): When demand for electricity is lowest, year-round.
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.
Tiered
With Tiered prices you have 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. You’ll be charged a lower price up to that threshold. Once the threshold is exceeded, a higher price will be applied to usage after the threshold.
The winter period (November 1 – April 30) threshold for residential customers is 1,000 kWh per month, so that households can use more power at the lower price. The summer period (May 1 – October 31) threshold for residential customers is 600 kWh per month. For small business customers, the threshold is 750 kWh throughout the year.
