The U.S. Department of Energy issued an emergency order late Tuesday to keep an aging Colorado coal plant open, just one day before it was slated to close.

The plant — Unit 1, part of Craig Station, in Moffat County — is now required to keep running until March 30, 2026. The order can also be extended.

The move drew a furious response from the governor’s office and environmental groups, who contest whether an emergency even exists that would require the plant to stay open.
