Most of our customers pay Ontario Energy Board set time-of-use electricity prices. Time-of-use divides the day into three rate periods:
- Off-peak, when demand for electricity is lowest.
- Mid-peak when demand for electricity is moderate.
- On peak when demand for electricity is highest.
The rate you pay for electricity in each of these periods reflects the costs of supplying electricity at that time of day. When demand for electricity is lower, electricity is less expensive. More expensive sources of electricity are used when demand is higher, which in turn makes the price higher.
There is both a Winter and Summer schedule for Time-of-use pricing which are set by the Ontario Energy Board and are reviewed every May 1 and November 1. The Ontario Energy Board reviews rates every 6 months. For additional information on time-of-use pricing and time periods, visit the Ontario Energy Board Web site.
Summer Time- of - Use: May 1 - October 31
In Summer, electricity use peaks during the hottest part of the afternoon, when air conditioners are running on high. On-peak hours are mid-day.
Winter Time - of - Use: November 1 - April 30
In Winter, less daylight means electricity use peaks twice: once in the morning when people wake up and turn on their lights and appliances, then again when people get home from work. These are two sets of on-peak hours to reflect this.
