What to do during a power outage

Power outages can last for minutes, hours, days or even weeks. They can be caused by rain storms, snow storms, high winds, or when there is too much demand placed on the city’s electrical grid. During a power outage, you may be without heating, hot water, or lighting. It is important to be prepared and to stay safe.

How to prepare for a power outage

  • Keep a 72-hour emergency preparedness kit readily accessible in an easy-to-reach location. This kit will contain commonly needed supplies to support a family for up to 3 days.
  • Protect all electronic devices with a surge protector. This can prevent damage to appliance in the event of a power surge.
  • Purchase back-up batteries for your essential electronics.

Staying​ safe during a power outage

  • Check with neighbours to see if the power outage is only affecting your home. If only your house is without power, check the circuit breaker panel or fuse box.
  • Report a power outage​ or a downed power line the Enmax Power Trouble Line at 403-514-6100.
  • Turn off or disconnect any electrical appliances and equipment to prevent damage from overload when turned back on.
  • Ensure you have access to a cell phone so you can be contacted by family and friends and stay informed on the status of the power outage. Alternatively, listen to a battery-powered or wind-up radio for information.
  • Keep one light on so you know when the power comes back on.
  • Do not use camp stoves, kerosene heaters or barbeques indoors, as they emit carbon monoxide​. Gas stoves used as a heat source for long periods of time without ventilation will do the same.
  • Limit how often you open and close your refrigerator and freezer doors to help food stay cool. Additionally, use a cooler filled with ice or snow to keep food cold.

After a power outage

  • Turn on only the most essential appliances. Wait 10 to 15 minutes before reconnecting other appliances.
  • Check the fridge, freezer and cupboards for spoiled food. If the power is out for more than 48 hours, all refrigerated food must be thrown out.

​​​​​​​​​​​What to do if you see a downed power line

  • To report a power outage or a downed power line in Calgary, call the ENMAX Power Trouble Line at 403-514-6100.
  • Call 9-1-1 immediately for any emergency or life threatening situations.
  • Do not approach or touch the power line. Assume that downed lines are energized. Keep yourself, pets and others at least 10 meters (33 feet) from the wires or anything that is in contact with the wires.
  • Warn others of the hazard.
  • Do not attempt to drive over a downed electrical wire. If the wire has fallen on a car, do not approach the car or attempt to rescue the person in the car.
  • If you are in a vehicle with a downed line touching it, do not get out of the car unless the car is on fire. If you must get out, jump as far away from the car as possible, and then hop or shuffle your feet to avoid shock.
