About Time of Use and Ultra Low Ovenight prices
With TOU and ULO 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.
With TOU, there are three price periods:
Off-peak: When demand for electricity is generally lower. 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 personal electronics and running heaters or air conditioners.
With ULO, there are four price periods:

About tiered prices
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.
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.
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.
