Herbert Wagner Generating Station

From Global Energy Monitor

Herbert A. Wagner Generating Station is a 359.0-megawatt (MW) coal-fired power station owned and operated by Talen Energy near Curtis Bay, Maryland.

In November 2020 Talen Energy announced the plant would stop using coal by the end of 2025.[1]

Location

The plant is located on Fort Smallwood Road north of Orchard Beach in Anne Arundel County, Maryland, near Glen Burnie. It shares a 483-acre (195 ha) site adjacent to the Patapsco River with the Brandon Shores Generating Station.

Ownership

The plant was originally constructed by a predecessor company of Constellation Energy, which was later purchased by Exelon in 2012. On August 9, 2012, Exelon announced that it had reached an agreement, subject to regulatory approvals, for the sale of the Crane Generating Station, Brandon Shores Generating Station, and Herbert Wagner Generating Station to Raven Power Holdings LLC, a newly formed portfolio company of Riverstone Holdings LLC, for approximately US$400 million. Exelon committed to divest the plants as condition for regulatory approval of its merger with Constellation Energy to alleviate concerns regarding potential market power in the regional wholesale electricity market.[6]

Talen Energy assumed ownership of the plant on June 1, 2015, under Riverstone Holdings, LLC.[7]

Death and disease attributable to fine particle pollution from Wagner Generating 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.[8] 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.[9]

Type of Impact Annual Incidence Valuation
Deaths 22 $160,000,000
Heart attacks 38 $4,100,000
Asthma attacks 360 $19,000
Hospital admissions 18 $410,000
Chronic bronchitis 14 $6,000,000
Asthma ER visits 16 $6,000
