Preparing for an outage or a planned service interruption

Planned service interruption: Tips to ensure your comfort

  • In winter, your home can become uncomfortable when the heating is off. Although most planned service interruptions generally don’t last long, it’s a good idea to preheat your home by turning up your thermostats by a few degrees about one hour before the service interruption is scheduled to begin.
  • Charge your electronic devices in advance so you can use them for work or entertainment during the service interruption.
  • Consider downloading movies, music or documents for work or school before the service interruption, as you won’t have Internet access.
  • To maintain the temperature of the refrigerator or freezer, plan your snacks so that you won’t have to open the fridge or freezer doors unnecessarily.
  • Track the status of the work on the Power outages map on our website or with our mobile app.

Prepare an emergency kit!

In the case of a power outage, it’s a good idea to have a kit that contains things like a flashlight, batteries and first-aid supplies. Store it in an easily accessible location and make sure that everyone in your home knows where it is!

  • Battery-operated flashlight to avoid using candles
  • Spare batteries for your flashlight and other devices
  • Games, books or other pastimes to keep busy
  • Battery-operated radio or a portable charger for mobile devices so you can monitor the situation from the map on the Power outages map on our website or with our mobile app.
  • Non‑perishable food to avoid opening the refrigerator
  • First‑aid supplies
  • Supplies for people with special needs, if necessary
  • Blankets to stay warm
  • List of important phone numbers (home and businesses)
