Unit Retirement

In September 2020, plant owner Vistra Energy said the Joppa power station would fully retire by the end of 2025.[2][3]

On April 6 2021, PR Newswire reported that the Joppa Power plant will close in 2022, 3 years earlier then previously reported.[1]

Plant ownership

The plant was owned by Ameren, an Illinois power company. In mid-March 2013, Dynegy purchased three electric generating subsidiaries and five coal plants from Ameren, including Joppa Station.[4][5]

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.[6]

Death and disease attributable to fine particle pollution from Joppa Steam 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.[7] 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.[8]

Type of Impact Annual Incidence Valuation
Deaths 40 $290,000,000
Heart attacks 61 $6,700,000
Asthma attacks 670 $35,000
Hospital admissions 28 $670,000
Chronic bronchitis 24 $11,000,000
Asthma ER visits 42 $15,000

Joppa ranked 75th on list of most polluting power plants in terms of coal waste

In January 2009, Sue Sturgis of the Institute of Southern Studies compiled a list of the 100 most polluting coal plants in the United States in terms of coal combustion waste (CCW) stored in surface impoundments like the one involved in the TVA Kingston Fossil Plant coal ash spill.[9] The data came from the EPA's Toxics Release Inventory (TRI) for 2006, the most recent year available.[10]

Joppa Steam Plant ranked number 75 on the list, with 366,675 pounds of coal combustion waste released to surface impoundments in 2006.[9]
