| Unit name | Status | Fuel(s) | Capacity (MW) | Technology | CHP | Start year | Retired year |
|---|---|---|---|---|---|---|---|
| 4 | Operating[1] | fossil gas: natural gas[1] | 149[1] | steam turbine[1] | yes[1] | 2017[1][2] | – |
| Unit 3 | Operating | coal: bituminous | 50 | subcritical | – | 1958 | 2025 (planned) |
| Unit 4 | Retired | coal: bituminous | 148.8 | subcritical | – | 1967 | 2017 |
CHP is an abbreviation for Combined Heat and Power. It is a technology that produces electricity and thermal energy at high efficiencies. Coal units track this information in the Captive Use section when known.

Retirements
According to plans filed with the Minnesota Public Service Commission on November 1, 2010, Alliant Energy plans to immediately close coal-fired boilers at six sites in Iowa, including unit 2 (23 MW) of Prairie Creek.[3][4]
In 2015 Alliant Energy said it was planning to convert unit 4 (149 MW) from coal to natural gas in 2017.[5] Unit 4 was converted to natural gas in November 2017.[6]
Units 1 and 3 are scheduled for retirement in 2025.[7]
May 2011: Fire
On May 19, 2011, officials said firefighters used water and foam on smoldering coal at the Prairie Creek plant. Alliant Energy workers reported that smoke was coming from a coal bunker. Firefighters cooled the smoldering coal with some water, then raised a hose up 10 stories and pumped foam into the top of the bunker. They also put foam on smoldering coal in two nearby bunkers. No injuries were reported, and the cause of the fire is being investigated.[8]

Death and disease attributable to fine particle pollution from Prairie Creek
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.[10] 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.[11]
Table 1: Death and disease attributable to fine particle pollution from Prairie Creek
| Type of Impact | Annual Incidence | Valuation |
|---|---|---|
| Deaths | 17 | $130,000,000 |
| Heart attacks | 27 | $3,000,000 |
| Asthma attacks | 290 | $15,000 |
| Hospital admissions | 12 | $290,000 |
| Chronic bronchitis | 11 | $4,700,000 |
| Asthma ER visits | 18 | $7,000 |
