Consumers Energy cancels Karn/Weadock expansion, announces retirement of seven aging coal units, and develops two new wind farms
On December 2, 2011, Consumers Energy announced that is was cancelling the proposed 800 megawatt Karn/Weadock Generating Complex Expansion because of "reduced customer demand for electricity due to the recession and slow economic recovery, surplus generating capacity in the Midwest market, and lower natural gas prices linked to expanded shale gas supplies." In addition, the company announced that it was suspending operations by the end of 2014 at seven existing generating units, included two units at the Whiting Generating Plant, two units at the Cobb Generating Plant, and two at the Karn Weadock Generating Complex. The company reported that it began construction in November 2011 of its first wind farm, the 100 MW Lake Winds Energy Park, in Mason County. Consumers Energy is also developing the 150 MW Cross Winds Energy Park in Tuscola County.[3]
Death and disease attributable to fine particle pollution from Cobb Generating 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.[4] 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.[5]

| Type of Impact | Annual Incidence | Valuation |
|---|---|---|
| Deaths | 34 | $250,000,000 |
| Heart attacks | 55 | $6,000,000 |
| Asthma attacks | 580 | $30,000 |
| Hospital admissions | 25 | $590,000 |
| Chronic bronchitis | 21 | $9,400,000 |
| Asthma ER visits | 35 | $13,000 |
