NorthWestern Energy is in the early stages of significant updates to its electric transmission infrastructure in south central Montana, with the work to be focused primarily in Stillwater and Carbon counties. Improving the reliability of electrical service to area customers and the region, as well as providing additional capacity due to electric load growth in the area, are the primary goals of the project, which will take place in phases over a 10-year period.

The Carbon-Stillwater Electric Transmission Infrastructure Project will improve the reliability of electric service for NorthWestern Energy's customers in the Columbus-Absarokee-Red Lodge area, including those customers served by other area electric cooperatives. It will also address growing demand for electricity in the area due to current and future growth. Key components of the project will include upgrades to several substations and existing transmission lines in the area and the construction of a new 100 kV transmission line. The new 100 kV transmission line is the first phase of the Carbon-Stillwater Electric Transmission Infrastructure Project. details of the future project phases will be announced as plans become finalized.
