Colstrip – NorthWestern Energy and Puget Sound Energy Reach Agreement on Unit 3

Shutting down Colstrip Unit 3 becomes much easier under an agreement between  power plant owners Puget Sound Energy and Northwestern Energy according  to regulatory filings in Washington. They reveal Puget expects to dictate the Montana utility’s vote when it comes to closing Unit 3 sometime in the next five years. Puget plans to sell its 25% interest in Unit 4 to Northwestern in the coming months for the aggregate price of $1 and would retain its 25% share in Unit 3.
