Urquhart Station is a 650 megawatt fossil fuel power station owned and operated by SCANA near Beech Island, South Carolina.
The coal plant was retired in 2012-2013 and converted to a 650 MW natural gas plant.
Retirement and fuel conversion plans
On May 30, 2012, SCE&G announced plans to retire up to six coal-fired generating units at three locations by the end of 2018. The units range in age from 45 to 57 years and are the utility's oldest and smallest coal-fired units. The announcement included the following:
- Switching Unit 3 at the Urquhart Station near Aiken from coal to natural gas by the end of 2012, and planned retirement of Unit 3 at Urquhart by the end of 2018.

Death and disease attributable to fine particle pollution from Urquhart 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. 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.
