Frequently asked questions
About dynamic pricing
Why has Hydro‑Québec come up with these rate offerings?
With these offerings, everyone is a winner. If you can reduce or shift electricity use at Hydro‑Québec’s request, you benefit, because your efforts translate into savings. Hydro‑Québec benefits because of the lower electricity demand during peak periods.
Would Hydro‑Québec consider extending dynamic pricing to the summer?
No. In contrast to our Canadian and American neighbors, the demand for electricity in Québec is very strongly influenced by the use of electric heating systems in most homes. As a result, demand is much higher in winter than in summer. Even if air-conditioning use were to increase in Québec, it’s unlikely that demand would reach peak levels requiring the implementation of dynamic pricing in summer.
Am I required to sign up for the Winter Credit Option or Rate Flex G?
No. It’s up to you whether to take advantage of dynamic rate offerings or not, and you can cancel anytime.
Why limit the number of participants?
We’ve chosen to roll out our dynamic rate offerings gradually, and therefore to limit the number of participants, so that we can provide optimal customer support. We’ll take participants’ feedback into account as we roll out dynamic pricing on a larger scale. Eventually, dynamic pricing will be available to all customers, who will be able to opt in if they wish, subject to eligibility criteria.
Can I put my name on a waiting list?
No. You’ll have to wait for the sign-up period starting September 8 for the opportunity to sign up for one of the two dynamic rate offerings. If the maximum number of customers has already signed up, you’ll have to wait for the next phase of the rollout.
Can I sign up for Rate Flex G if my service contract is at Rate M or G9?
If you have a Rate M or G9 service contract and you’d like more information about the dynamic Flex rate, please call 1 800 463‑9900 or write to firstname.lastname@example.org.
Peak demand events
When do peak demand events occur?
Peak demand events can take place 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.
How cold does it have to be to trigger a peak demand event?
There is no pre-established threshold, but the temperature is an important factor.
Peak demand events are scheduled when we anticipate high demand for electricity in Québec in winter. That’s the main consideration. It’s true that on cold days everyone uses a lot of energy at the same time, so the temperature has an impact on demand forecasts. However, demand isn’t always the same for a given temperature. For example, if it is -10°C for several days in a row, demand for electricity will be greater on the last day than on the first.
Other factors that affect the forecasted demand have to do with operating constraints related to electricity supply as well as power transmission and distribution. To manage power demand, Hydro‑Québec diligently applies all the means at its disposal, including dynamic pricing.
Why don’t peak demand events occur systematically every day during peak hours?
By targeting fewer hours (maximum of 100 per winter), we can offer a more significant price difference between peak periods and off-peak periods, which optimizes your savings potential.
