On August 21, 2019, plant owner Vistra announced that the power plant will be retired before the end of 2019 if it is determined that the unit is not needed for network reliability. Vistra Energy said it needed to close the plant to meet the requirements of the recently approved revisions to the Multi-Pollutant Standard rule of the Illinois Pollution Control Board.[1]

The power station was retired on November 1, 2019.[2]


Formerly run by Central Illinois Public Service Company and later Ameren, Ameren sold the plant to Dynegy in 2013.[3]

On April 9, 2018, Texas-based Vistra Energy, the parent company for TXU Energy and Luminant, announced it had completed its merger with Dynegy. Vistra Energy will be the name of the combined company moving forward.[4]

Emissions Data

  • 2006 CO2 Emissions: 6,843,640 tons
  • 2006 SO2 Emissions: 22,007 tons

Pollution controls

At the end of 2009 it was announced that Ameren Energy Resources had spent US$1 billion for the installation of scrubbers at two of its facilities, including the Duck Creek Station and the Coffeen power station. The scrubbers reduce nitrogen oxide and sulfur dioxide emissions.[5]

Death and disease attributable to fine particle pollution from Coffeen power 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.[6] 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.[7]

Type of Impact Annual Incidence Valuation
Deaths 28 $210,000,000
Heart attacks 43 $4,700,000
Asthma attacks 480 $25,000
Hospital admissions 21 $470,000
Chronic bronchitis 17 $7,700,000
Asthma ER visits 30 $11,000
