    • About

      NorthWestern Energy has provided reliable and affordable energy to customers in Montana, South Dakota and Nebraska for more than 100 years. Our company got its start in small communities, providing essential service that allowed them to grow and prosper. Today, we are proud to serve 734,800 residential and business customers with electricity and natural gas.

      With roots in the Montana Power Co. and South Dakota-based Northwestern Public Service Co., NorthWestern Energy took its current form in 2002 when the company bought the Montana Power electric and natural gas transmission and distribution system and became a partial owner of Colstrip Unit 4.

      Today, the company is a growing, financially sound, investor-owned energy company. Shares in NorthWestern Energy are traded on the New York Stock Exchange under the symbol NWE.
