Gibbons Creek Steam Station is a coal-fired power station owned and operated by the Texas Municipal Power Agency near Carlos, Texas.

In July 2017 it was reported that, due to competition from lower-cost renewables and gas, the plant would only run during the hot summer months (June through September). Texas Municipal Power Agency (TMPA) has been looking to sell the coal plant for nearly a year. The deadline to sell is September 2018, at which point the TMPA board will have to decide whether to shut down operations at Gibbons Creek completely.[1]

Scrubber Retrofit at Gibbons Creek Steam Station

In March 2011, Texas Municipal Power Agency, which owns the coal-burning Gibbons Creek plant, stated they are installing a scrubber to meet new federal standards and limit the amount of mercury and other pollutant emissions. Workers are to have to installed the scrubber by April 1, 2011. The cost of the scrubber installation will run $98.5 million, stated the company.

Death and disease attributable to fine particle pollution from Gibbons Creek Steam 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.[2] 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.[3]

Type of Impact Annual Incidence Valuation
Deaths 3 $23,000,000
Heart attacks 5 $510,000
Asthma attacks 57 $3,000
Hospital admissions 3 $53,000
Chronic bronchitis 2 $890,000
Asthma ER visits 4 $1,000
