Increasing reliability

NorthWestern Energy’s $7.8 million new Chamberlain switchyard project will increase capacity to provide reliable service for our customers in the Chamberlain area.

NorthWestern Energy is working jointly with East River Electric Cooperative and Central Electric Cooperative. The new switchyard and East River’s new substation are being built on 10 acres located southeast of the City of Chamberlain near the intersection of 249th Street and 345th Avenue.

The new infrastructure will increase reliability and provide uniformity on the transmission system that serves customers in the area through the joint effort of NorthWestern Energy and East River Cooperative.

Expect some traffic detours

Work will begin in May and is expected to be completed by the end of the year. Some traffic detours and delays will be required for the safety of the public and crews working on the upgrade.

We appreciate the public’s cooperation and patience when traffic detours or delays are needed for the safety of both the public and crews. Watch for “Utility Work Ahead” signs which alert that crews are working in the area.
