Units 1 and 2 of the coal-fired power plant in Colstrip will permanently close at the end of this year. Plant operator Talen Energy made that announcement in a press release Tuesday, saying the company has been unsuccessful in making the units economically viable. Talen says the plant’s newer units, 3 and 4, will remain open.
