Coal to Natural Gas

GRDA started construction of a new 495MW combined cycle gas turbine unit at the site in January 2015 at an estimated cost of $296 million. The new gas unit is expected to start operations in March 2017, at which time unit 1 will retire. Unit two will be retrofitted to control emissions in accordance with EPA standards by 2016.[3]

In April 2017, the US DOE allowed Unit 1 of Grand River Energy Center to keep running until unit 3 was brought online "to ensure grid reliability", as unit 2 was offline for repairs.[4][5][6][7]

Due to delays in building Unit 3 and a fire which severely damaged and incapacitated Unit 2, GRDA officials did not take unit 1 offline until late 2018. In August 2019, GRDA voted to decommission the unit.[8]

Unit 1 is now listed in the EIA database as a 40 MW natural gas steam turbine together with natural gas fired combined cycle units 3CT and 3ST it makes the new unit 3.[2]

Death and disease attributable to fine particle pollution from Chouteau Plant

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.[9] 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.[10]
