Unit Retirements

In February 2019 plant owner MDU said the plant is scheduled for retirement in 2020. MDU’s plan to close the plant came just three years after the company installed US$16 million in pollution controls at the plant to comply with federal Mercury Air Toxics Standards (MATS). The costs were passed on to customers.

In March 2020, Jay Skabo, the vice president with MDU, said during a meeting that the retirement date was moved to March 2021.

On March 29, 2021, the Montana Free Press reported that the power plant would close on March 31, 2021.
