Alectra Utilities' (formerly Horizon Utilities) residential and small business customers are billed based on Time-of-Use (TOU) rates, with the exception of those who do not yet have a smart meter installed and those who pay for their electricity on a contract with an energy retailer. With a retail contract, customers typically pay the same amount for electricity no matter what time of day it is used.
With TOU rates, the cost of electricity varies depending on when you use it (off-peak, mid-peak and on-peak). Rates are different depending on the time of the day, day of the week and season of the year (summer and winter).
TOU rates reward you for using electricity during low-demand periods whenever possible (reflected in green). As you can see from the seasonal charts below, the lowest rates are at night, on weekends and statutory holidays.
TOU Rates effective July 1, 2017
There was no change in rates November 1, 2016.
Summer weekday rates (May 1 to October 31)
On-peak rates apply during the middle of the weekday (between 11 a.m. and 5 p.m.). This is mainly due to the increase in air conditioning use during the hottest hours of the day.
Winter weekday rates (November 1 to April 30)
The winter months have two on-peak periods. During these times, increased space heating, lighting and appliance use is common. The
on-peak rates apply in the morning
(7 a.m. to 11 a.m.) and evening
(5 p.m. to 7 p.m.). The off-peak period begins at 7 p.m.
Weekends and holidays
On weekends and holidays, all hours of the day are off-peak. The demand for electricity in the province is less. Therefore, electricity rates are lower on weekends and holidays. Below is a list of the upcoming TOU holidays:
|New Year's Day||Civic Holiday|
|Family Day||Labour Day|
|Good Friday||Thanksgiving Day|
|Victoria Day||Christmas Day|
|Canada Day||Boxing Day|
Note: If a holiday falls on a weekend, the following Monday will have off-peak prices in effect all day. |
How are Time-of-Use rates set?
The Ontario Energy Board reviews the TOU rates based on electricity market prices over the previous six months as well as its forecast of future electricity prices over the next year.
TOU rates reflect the fact that the cost to provide electricity changes throughout the day. When demand is low, less expensive sources of electricity are used. When demand rises, more expensive forms of electricity production are called upon, making prices higher.
