Hydro Quebec says it is managing the current cold snap well.
But with temperatures expected to continue in the negative double digits next week, the utility is relying on both personal and industrial consumers to keep their electricity use down when possible.
Hydro says even a one degree change in temperatures has a big effect on overall energy consumption.
So with temperatures warming slightly next week, the utility is confident it can provide reliable service through the cold snap.
But it is still asking users to turn their heating down in rooms that aren't in use and when they leave the house.
Keeping baseboard heaters and appliance coils dust free will also help them run more efficiently.
