Be prepared, stay safe! Extreme wind event forecasted across our service area this week.

The U.S. Weather Service is forecasting extreme winds this week.

Our crews are prepared with additional staffing, equipment, and supplies to respond as quickly as possible, safely, to weather‑related outages.

It’s critical to stay away from downed or low‑hanging power lines. If you see a damaged or fallen line, keep your distance and report it immediately. Never touch a power line or anything in contact with it, including trees. Keep people, pets, equipment, and objects at least 30 feet away, and never attempt to remove a fallen tree or branch from a power line.

For the latest weather alerts and forecasts, visit the South Dakota National Weather Service sites at Sioux Falls, SD and Aberdeen, SD.

Our emergency line is available 24 hours a day.

Montana: 888-467-2669 | South Dakota/Nebraska: 800-245-6977 | In case of a life-threatening emergency, dial 911.

Power is especially critical to customers who use life-support devices. NorthWestern Energy works hard to prevent power outages, but here are some things you can do to be prepared for an outage:

Have an alternate plan in place to ensure the continuity of any life-support needs. This may include making special arrangements to spend time with a friend or relative during an outage or using a back-up generator.
If you use a back-up generator, please understand that customers are responsible for the safe installation, use, and maintenance of any back-up power.
In the event emergency assistance is needed, please call 911.

NorthWestern Energy will make an attempt to notify you if your service will be interrupted due to planned maintenance, repair or construction. We are unable, of course, to provide advance notice of unscheduled power interruptions due to such events as storms, accidents, or equipment failure.
