Xcel Energy says it wants to shut down the Cameo Power Plant by the end of 2010.
Company officials told Mesa County Commissioners and residents it wants to close it because it's 50–years–old and would cost too much to upgrade.
Xcel also says the plant burns coal, so closing it would help lower emissions.
The company says 35 people who work in the plant will keep their jobs.
Before the plant can be shut down, the Colorado Public Utilities commission must approve the plan.
