Background
Units 1-3 were built in the 1960-70s.[1] Dallman Unit 4 began operating on June 1, 2009.[2][3]
In October 2023, the Illinois Attorney General filed a lawsuit against City, Water, Light and Power (CWLP), alleging that the utility's Dallman Station released over 700 tons of coal ash into the environment in August 2021.[4]
Planned retirement
Units 1-2 retired on schedule in December 2020.[5] Unit 3 was schedule to retire by 2023.[6] However, storm damage sustained in 2021 caused CWLP to retire the station early due to the high costs of repair it would take to return the unit to service.[7]
Carbon Capture and Storage
In 2021, the Illinois Sustainable Technology Center (ISTC) announced plans to design and build a pilot 10 MW carbon capture project at Dallman Unit 4. The ISTC is part of the Prairie Research Institute (PRI) at the University of Illinois. Funding for the pilot project was expected to come from the US Department of Energy (US$58 million), the State of Illinois (US$20 million), and Linde-BASF (US$7 million). Construction was slated to begin in June 2022, followed by testing from March 2024 through May 2026.[8][9]
In May 2023, the Department of Energy (DOE) selected ISTC to conduct an additional study on “integrated capture, transport, and geological storage” of carbon emissions from Dallman Unit 4. The DOE would provide US$4.7 million for a front-end engineering design (FEED) study to evaluate the feasibility of a 200 MW carbon capture system and technology to transfer and store captured emissions in the “Illinois Storage Corridor”.[8]
In June 2024, a ribbon-cutting ceremony was held for the upcoming testing of the 10 MW carbon capture pilot project at Unit 4. According to the website for City Water, Light, and Power, the “pilot system will process approximately 5 percent of the unit’s flue gas, from which it will demonstrate the ability to capture over 90 percent of the slipstream’s CO2 emissions.”[8]

Death and disease attributable to fine particle pollution from Dallman
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 Dallman Station
| Type of Impact | Annual Incidence | Valuation |
|---|---|---|
| Deaths | 3 | $23,000,000 |
| Heart attacks | 5 | $540,000 |
| Asthma attacks | 54 | $3,000 |
| Hospital admissions | 3 | $54,000 |
| Chronic bronchitis | 2 | $880,000 |
| Asthma ER visits | 3 | $1,000 |
