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.

Billings Rimrock Substation Rebuild

Reliable service for a growing community

Reliable service for a growing community

Growth is strong in Yellowstone County, and NorthWestern Energy invested almost $76 million in electric system upgrade projects to support population and industrial growth and increase energy service reliability for our customers.

The $34 million Rimrock Substation upgrade was completed in 2023 and increased capacity to provide service for increased energy demand in the Billings area. Redundancy enhancement also improved reliability for customers.
