Disclaimer: During large outages or severe weather conditions the data available may be limited, delayed, or not totally accurate. Outage data is provided without any guarantee or warranty of any kind, expressed or implied.
This map indicates areas of current planned and unplanned outages and the estimated time of restoration.  Please be aware that field crews provide the estimated restoration time and/or dispatchers based upon what is known about the situation.  Our workers strive to restore power to your home as quickly and as safely as possible but occasionally crews encounter unforeseen circumstances when working on repairs.  Therefore, sometimes power may be restored sooner or later than the estimated time noted in the map. 

If you have been out of power for more than ten minutes and it is not appearing on the map, please call one of the numbers at the top of the page or log into My Energy Account and use our online form to report an outage.  And remember, always treat a downed or low-hanging line as live.

Frequently Asked Questions

Learn more about what to expect during a power outage.

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.

You can fill empty space in your freezer with perishable items from your refrigerator, which will help keep these items fresh and help your freezer keep it's temperature. You can also fill your freezer with jugs of water or bags of ice.

If the power doesn't come back on after four hours, you may want to consider buying ice and filling a cooler. Move perishable items from your fridge to the cooler. Use a thermometer to make sure the cooler stays below 40 degrees. Add ice as needed.

Strong winds, ice and heavy snow can lead to downed power lines. If you see a downed or damaged power line, keep your distance and call 911 immediately.

Never touch a power line or any object, including trees, that is in contact with a line. Remember:

  • Keep people, equipment and objects at least 30 feet away from power lines.
  • Never attempt to remove a fallen tree or branch from a power line. You could be seriously injured or killed.
  • If a tree or branch does come in contact with a power line, keep yourself and others away from the tree and call 911 and NorthWestern Energy immediately.

Outages occur for many reasons. Here are the most common causes of unplanned outages:

  • System equipment, such as service lines, underground conductor, transformers and insulators.
  • Birds and squirrels.
  • Debris on the pole or in the line.
  • Weather, such as snow, thunderstorms or extreme temperatures.

This can vary greatly depending on the cause of an outage. Sometimes restoring power is as simple as removing a branch that has fallen on a line. Other times, it might require replacing a pole that was hit by a vehicle or blown over in a storm. Sometimes we can switch customers to a different circuit while we make repairs, greatly reducing outage time. If a major storm knocks down numerous poles and takes out several lines, an outage can last hours or even days.

Our top priority is always the safety of our crews and our customers. While restoring power quickly is our goal, our crews take the time required to make repairs safely.

Your neighbor’s home may be fed by a different service or distribution line. It’s also possible the cause of the outage is

in your home. Be sure to check your fuses or breaker box.

Check fuses or circuit breakers to rule out problems with electricity inside your home. If there’s not an issue with your fuses or breakers, report the outage to NorthWestern Energy. You can report outages online or by calling:
