How does Rate Flex D work?
With Rate Flex D, you can save quite a bit of money, since most of the time in winter, you’ll be charged less than the base rate, except during occasional peak demand events, when you’ll be charged more than the base rate.
Rate Flex D is different from the base rate (Rate D). This is how it works:
- In winter,
- Outside peak demand events, i.e., during more than 95% of the season, the price of electricity is below the base rate.
- During peak demand events, i.e., during 5% of the season at most, the price of electricity is higher than the base rate.
- The rest of the year, Rate D (base rate) prices apply.
Peak demand events
- Peak demand events can take place Monday to Friday 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. The number of hours of peak demand events may vary from one winter to the next, depending on the demand forecast, which fluctuates according to the weather and the state of the grid.
- How much you save will vary based on the number of peak event hours accumulated during the winter.
- The day before a peak demand event, you’ll be notified by email before 5 p.m. (as well as on the mobile app if requested).
Doing the right thing at the right time
To maximize your savings with Rate Flex D, the trick is to reduce your energy use during peak events by turning down your thermostats at the start of a peak event and delaying your use of hot water until the event is over.
A tool that lets you track your results
To see the results of your energy‑saving efforts, use the Energy Performance Indicator in your Customer Space, which lets you track:
