Do peak demand events always take place at the same time for Rate Flex D customers and for customers enrolled in the Winter Credit Option?

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 as one another 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 through the Hilo mobile app. The notification, which includes the event start and end times, is also available in your Customer Space.
