How Rate Flex G works

Rate Flex G is different than the base rate (Rate G). This is how it works.

  • In winter
    • outside peak demand events, the price of electricity is below the base rate, so you can save money.
    • during peak demand events, electricity is billed at a high price (/kWh). You’ll have to shift nonessential electricity use or limit it to reduce costs. The day before a peak demand event, you’ll receive a notification by email and, if you like, through our mobile app.
  • The rest of the year, the price of the first tier of Rate G (base rate) applies.


The risk depends on your energy use habits. Your bill could be higher at Rate Flex G than at the base rate if you don’t take the necessary steps during peak demand events when the price is higher. It’s important to use as little electricity as possible during those events, so you aren’t penalized.

A mild winter versus a cold winter

The number of hours of peak demand events may vary from one winter to the next, according to the electricity demand forecast, which fluctuates depending on weather conditions and the state of the grid. In a winter season with only a few peak periods, your potential savings will be higher, whereas in a winter with several peak periods (a maximum of 100 hours), you will likely save less. By reducing your electricity use as much as possible during peak periods, you are sure to save!

Peak demand events

Peak demand events can take place weekdays from December 1 to March 31, from 6 to 9 a.m. and from 4 to 8 p.m. There may be 25 to 33 events per winter, at most, for a maximum of 100 hours in all.

A customized tool to track your results

You can see the results of your efforts in the Consumption Profile in your Customer Space. It tells you the following:

  • Information about the current winter, updated daily (total savings or increase, number of hours in peak demand events already gone by, number of days of the winter period elapsed)
  • Your energy use during peak demand events and outside events
  • Upcoming events for which you have received a notification
