Cameo Station is a coal-fired power station owned and operated by Xcel Energy near Palisade, Colorado, located on the western side of the state, about 45 miles from the Utah border, on the Colorado river.
In Nov. 2007, Xcel announced that it planned to shut Cameo down by the end of 2010, citing the older plant's inefficiency and the opportunity to reduce carbon emissions. In Jan. 2009, Xcel announced plans to build a 1-MW test Concentrating Solar Power plant (the company's first) at the location, after Cameo is shut down. Construction is scheduled to begin in summer of 2009. However, as of July 2010, the plant was still burning coal.
Xcel develops world's first solar/coal hybrid power plant
In July 2010, the first ever solar-coal hybrid power plant began to operate in Colorado. The project was a joint endeavor between Xcel Energy and Abengoa Solar, the unit of Xcel’s Cameo Station is intended to show that solar power can reduce the environmental impact of coal-fired power plants. The plant uses parabolic trough solar collectors to heat the water that goes into the coal-fired turbine, which reduces amount of coal used at the facility by 2 to 3 percent. For a cost of $4.5 million, the hybrid plant will produce the equivalent of just one of 49 megawatts from solar power.

Death and disease attributable to fine particle pollution from Cameo Station
In 2010, Abt Associates issued a study commissioned by the Clean Air Task Force, a nonprofit research and advocacy organization, quantifying the deaths and other health effects attributable to fine particle pollution from coal-fired power plants. Fine particle pollution consists of a complex mixture of soot, heavy metals, sulfur dioxide, and nitrogen oxides. Among these particles, the most dangerous are those less than 2.5 microns in diameter, which are so tiny that they can evade the lung's natural defenses, enter the bloodstream, and be transported to vital organs. Impacts are especially severe among the elderly, children, and those with respiratory disease. The study found that over 13,000 deaths and tens of thousands of cases of chronic bronchitis, acute bronchitis, asthma, congestive heart failure, acute myocardial infarction, dysrhythmia, ischemic heart disease, chronic lung disease, and pneumonia each year are attributable to fine particle pollution from U.S. coal plant emissions. These deaths and illnesses are major examples of coal's external costs, i.e. uncompensated harms inflicted upon the public at large. Low-income and minority populations are disproportionately impacted as well, due to the tendency of companies to avoid locating power plants upwind of affluent communities. To monetize the health impact of fine particle pollution from each coal plant, Abt assigned a value of $7,300,000 to each 2010 mortality, based on a range of government and private studies. Valuations of illnesses ranged from $52 for an asthma episode to $440,000 for a case of chronic bronchitis.
