Save during winter peak periods Using less electricity during winter peaks is a winning solution

What’s a winter peak period?

In Québec, they usually occur on cold days, when we’re all using a lot of electricity at the same time and the grid is overloaded. Fortunately, winter peaks only happen a few days a year, from 6 to 9 a.m. and from 4 to 8 p.m.

What’s the solution?

Hydro‑Québec has offers that reward you when you shift your electricity use outside peak periods to help spread out demand more evenly.

Save on your bill when you sign up for dynamic pricing and earn cash rewards when you opt for the Hilo smart home service.

How to take action during winter peaks

Reducing electricity use during winter peaks is easier than you might think. Where to start? Hydro‑Québec has two great ways to help you save: dynamic pricing and the Hilo smart home service. If you haven’t signed up yet, what are you waiting for?

  • Turn down the heating

    Turn down all the thermostats in your home by at least 2°C at the start of a peak demand event.

  • Wait until the peak has passed to use hot water

    Whenever possible, use hot water after a peak period so that your water heater doesn’t switch on when the demand for electricity is high.

  • Wait until the peak has passed to use major appliances

    Make sure you put off using your washer, dryer and oven until after the peak period. Instead, opt for small appliances like the slow cooker, microwave or air fryer.

  • Wait until the peak has passed to charge your EV

    Program your EV to charge at night.

Why make a collective effort during winter peak periods?

By reducing our consumption during winter peaks, we are supporting the electrification of sectors in Québec that currently rely on fossil fuels.

In addition, we are helping to limit the purchase of costly and less sustainable electricity from neighboring markets and reducing future investments on the grid that would be necessary to meet the growing demand for electricity for only a few hours a year. This helps us to reduce our electricity bill and the pressure on electricity rates.

Positive results across Québec

During winter 2023‑2024, participating residential and business customers reduced power demand by 999 MW during each peak. That’s practically equivalent to the capacity of Outardes‑3 generating station!

Every household counts

An average of 352 MW curtailed during the winter period—enough to power about 50,000 households.

Businesses that are doing their part

An average of 647 MW curtailed during the winter period—enough to power about 92,500 households.
