Arapahoe Station was a coal-fired power station owned and operated by Xcel Energy near Denver, Colorado.
The plant was retired in 2013.

Plans to shut down Arapahoe and Cameo Generating Stations
In August 2008, Colorado regulators approved Xcel’s plan to shut down two coal plants: the Arapahoe Station and the Cameo Station (east of Grand Junction). According to Western Resource Advocates, "The utility’s decision to shut down the plants has been praised as the nation’s first voluntary effort to cut coal power generation in an attempt to reduce greenhouse gas emissions. In its decision to support Xcel’s plan, the Colorado Public Utilities Commission (PUC) cited public health benefits and shared concerns about carbon emissions as major selling-points in the company’s groundbreaking proposal. The verdict marks a collective effort to move the state and its utilities toward the carbon reduction goals outlined in Governor Bill Ritter’s Climate Action Plan."[1]
Xcel plans to replace the combined 229 MW of coal power with 850 MW of wind power and a 200 MW utility-scale solar power plant with storage capacity by 2015. Another key component of Xcel’s proposal, to build a 480 MW natural gas plant at the Arapahoe station, has been postponed pending approval by the Colorado PUC.[1]
The last two units of Arapahoe were retired in 2013. Two older 44MW units at the plant, built in the early 1950s, were retired in 2002.[2]

Death and disease attributable to fine particle pollution from Arapahoe 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.[3] 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.[4]

| Type of Impact | Annual Incidence | Valuation |
|---|---|---|
| Deaths | 4 | $27,000,000 |
| Heart attacks | 6 | $610,000 |
| Asthma attacks | 71 | $4,000 |
| Hospital admissions | 3 | $59,000 |
| Chronic bronchitis | 3 | $1,100,000 |
| Asthma ER visits | 3 | $1,000 |
