On December 31, Colstrip Steam Electric Station’s units 1 and 2 will be retired. Owned 50% by Talen Montana and 50% by Puget Sound Energy, the units have a total capacity of 614 megawatts. Colstrip’s other two units, 3 and 4, will remain in operation.
“The decision to retire Colstrip units 1 and 2 comes after extensive review and exhaustive efforts over the last few years to address the financial challenges that these units face,” said Talen Montana President Dale Lebsack. “The plant team has done a great job of responding to the challenges faced by units 1 and 2, but we have been unsuccessful in making the units economically viable.”
