Background on Pueblo Unit 3 (PU3) Coal Plant

Read Colorado’s Billion Dollar Mistake report for important background and history on why building a new coal plant in the 21st century was a mistake.

“In short, advocating for burning coal to secure Pueblo’s future and provide tax revenues for the next 19 years is not a strategy that is likely to work due to coal supply issues — independent of all the moral and environmental reasons to stop burning coal as quickly as we can.”

See Leslie Glustrom’s op-ed in The Pueblo Chieftain for more on a sustainable and equitable future for Pueblo.

The Public Utilities Commission Staff Report (20I-0437E) details an investigation into the history and ongoing implementation of the PU3 coal plant and its numerous operations and equipment problems.
