Unit Retirements

In December 2010, Kennecott Utah Copper announced that it would repower units 1-3 of its Utah Smelter power plant to run on natural gas by 2018. However, unit 4 (82 MW) of the plant will continue to be powered by coal.

Units 1-3 were shut down in 2016 and will be decommissioned in the near future.

The last coal unit, unit 4, was shut down in May 2019.
