For years, Montana’s political leaders have been advocating for technology that traps carbon at power plants and other industrial sites. So far, carbon capture has seen a slow start. The two candidates facing off for a Montana U.S. Senate seat in the upcoming November election recently highlighted their carbon capture initiatives.

Talen Proposes Partial Excavation Of Colstrip Waste Ponds

Sep 22, 2020

The company that operates the Colstrip coal fired power plant is proposing to partially excavate waste ponds that have been contaminating groundwater for decades.

State regulators are now accepting comments on the plan.

Talen Energy’s report explores ways to prevent future groundwater pollution from the Units 1 and 2 coal ash ponds, which are leaking coal ash contaminants like boron and sulfate into groundwater.

Montana state regulators will consider NorthWestern Energy’s proposed purchase in a greater share of the Colstrip coal fired power plant in mid December.

The Montana Public Service Commission (PSC) set a hearing date of Dec. 14 at its meeting on Aug. 25.

NorthWestern filed a motion on Aug. 14 to expedite the first hearing on its proposed 92-MGW acquisition in Colstrip unit 4 to November. Intervenors said that’s not enough time for discovery.

PSC staff’s suggested mid December hearing is before newly elected commissioners take their seats.

Montana's largest coal-fired power plant has begun demolishing equipment as part of a partial closure.

The Colstrip Power Plant started dismantling its Unit 1 and 2 cooling towers in July, the Billings Gazette reported Wednesday.

 

State regulators Wednesday will start considering whether Montana’s largest electric utility should be able to pass costs on to customers for money it lost in the summer of 2018.

 

Montana’s largest electric utility says another company is hedging in on its plan to purchase a greater share of the Colstrip coal-fired power plant.

BILLINGS, Mont. (AP) — One of the largest coal-fired power plants in the western U.S. will close two of its four units in coming days as the Montana facility edges toward an eventual total shutdown.


Amid constantly changing closure dates for a power plant majority owned by out-of-state companies, a town that found success through coal is coming to terms with the plant’s partial retirement. Kayla Desroches spent a day in Colstrip in southeast Montana to talk with some of the people who live and work in the community.
