Investing in Montana's Energy Future
We're investing in Montana's energy future through LED streetlights, a new generating station, upgraded meters, and substation rebuilds. We're committed to improving service reliability and keeping up with community growth. Our projects include a $34 million upgrade to the Rimrock Substation, rebuilding the Missoula City Substation, and the Mystic 50 kV Line rebuild.
Yellowstone County Generating Station
Yellowstone County Generating Station will provide on‑demand resources to support the variability of wind and solar projects coming onto our system and help serve our customers during extended periods of peak demand.
Montana Meter Upgrade
NorthWestern Energy will install 590,000 new electric meters and gas modules in Montana, which will help improve service reliability.
Madison Street Bridge Pipeline
The new pipeline will provide increased service reliability for NorthWestern Energy’s Missoula customers.
Billings Rimrock Substation Rebuild
The Rimrock Substation upgrade is a $34 million project to increase capacity to provide service for increased energy demand in the Billings area.
Montana LED Lighting
We're replacing 43,000 NorthWestern Energy-owned streetlights in Montana with LED lights. LEDs use 50% less electricity than traditional high-pressure sodium (HPS) lights.
Missoula City Substation Rebuild
This rebuild will provide improved reliability and increased capacity necessary to serve the growing areas of downtown and the university district into the future.
Red Lodge to Luther 50kV Transmission Line Rebuild
NorthWestern Energy will rebuild about 7.5 miles of the 50kV transmission line from the east Red Lodge Substation to Luther. The transmission line generally runs along 15th Street West within the town of Red Lodge, continuing around the south side of the city airport in Red Lodge, and west to Luther.
Powering South Dakota's Future
NorthWestern Energy is committed to investing in South Dakota's energy future through a variety of projects. We're replacing 17,000 NorthWestern Energy-owned streetlights and yard lights in South Dakota with LED lights, which use 50% less electricity than traditional high-pressure sodium (HPS) lights. We're also expanding natural gas service to the Tea and Harrisburg areas, and upgrading the Chamberlain switchyard to increase service reliability for customers in the Chamberlain area. Furthermore, we're seeking a regulatory electric rate review in South Dakota to support the continued strengthening of our electric system.
