FAQs
With Rate Flex D, you save all winter long because you benefit from a lower price than the base rate (Rate D) for 95% of the period. The cost of electricity only goes up during peak demand events, so those are the best times to reduce your consumption. When there are no peak demand events, your savings will increase every day until the end of the season, on March 31.
That's why the savings you see in your customer space vary every day during the period from December 1 to March 31.
The day before a peak demand event, you’ll receive a notification by email and, if you wish, through the Hydro‑Québec mobile app to notify you of the event start and end times. All peak demand event notifications will also be posted in your Customer Space.
Hydro-Québec cannot be held responsible for nonreceipt of a notification due to the failure of equipment belonging to you or your telecommunications provider.
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.
Peak demand events can take place from December 1 to March 31, from 6 to 10 a.m. and from 4 to 8 p.m., excluding December 24, 25, 26 and 31, and January 1 and 2, as well as Good Friday and Easter Monday when they fall within the winter period.
- Maximum number of events per day: 2 events
- Duration of an event: 4 hours
- Maximum total duration of events in the winter period: 120 hours
No. Hydro‑Québec can ask some or all of its customers enrolled in either Rate Flex D or the Winter Credit Option to reduce the pressure on the grid during peak periods.
Participating households can therefore be asked to reduce their electricity use at the same times or at different times based on system needs and the rate option chosen. The objective is to balance out demand and avoid additional costs associated with importing electricity and upgrading grid infrastructure.
Peak demand events can take place seven days a week, morning or night, regardless of the rate option chosen.
The day before a peak demand event, you'll receive a notification by email or through the Hydro‑Québec mobile app, or both. The notification, which includes the event start and end times, is also available in your Customer Space.
