What to do if your power goes out:

  • Do not open freezers or refrigerators more than necessary.
  • A refrigerator will keep food cold for about 4 hours if it is unopened.
  • A full freezer will keep the temperature for approximately 48 hours (24 hours if it is half full) if the door remains closed.
  • Check fuses or circuit breakers to rule out problems with electricity inside your home. If a fuse is blown, replace it with the appropriate fuse. If a breaker has tripped, reset it from off to on. If you are unsure about fixing a fuse or circuit breaker, call an electrician.
  • Check social media and our online outage map. If an outage is widespread, NorthWestern Energy will post updates on our Facebook and Twitter pages. You can also get up-to-date outage information from our online outage map at northwesternenergy.com/outage.
  • Turn off all but one light, so you will notice when we have restored your electricity.
  • Unplug computers, chargers, TVs, VCRs and other sensitive appliances to avoid possible damage when electricity is restored.
  • When power resumes, reset clocks and check automatic alarms and timers. Plug in only essential items. Wait 10 minutes before connecting the remainder of your items to let the electrical system stabilize.
  • Use a flashlight. Avoid candles because of the fire risk.
  • If you are using a portable generator, make sure you are doing so safely.
