NorthWestern Energy completes two-year $7.8 million Chamberlain switchyard, providing redundancy and increased reliability

Date: Nov 8, 2023

Sioux Falls, S.D. – Nov. 8, 2023 – NorthWestern Energy’s joint $7.8 million Chamberlain switchyard project is being completed this month.

NorthWestern Energy is working jointly with East River Electric, an electric cooperative based in Madison, South Dakota. The new switchyard will provide redundancy and increase reliability on the transmission system that serves customers in the area.

NorthWestern Energy recognized the opportunity for improvements with our local and regional partners. Work has been in progress in the Chamberlain area since 2021, when a substation transformer was replaced and upgrades were made to both transmission and distribution infrastructure serving the area, said NorthWestern Energy Director of South Dakota/Nebraska Operations Brad Wenande.

“The switchyard project will provide even better service reliability for our customers in the area,” Wenande said.

“It was a great accomplishment to partner with East River Electric and utilize our transmission systems already in place to make this reliability enhancement project economic,” said NorthWestern Energy Division Manager Jamie Hajek. “We listened to the feedback from communities served from this area of our system and followed through with a significant investment that will provide reliability benefits to our customers from Mt. Vernon to Chamberlain immediately.”
