The AES Westover power station in Johnson City, New York, was constructed in 1917 by the New York State Electric and Gas Corporation (NYSEG). Following an expansion to the facility in 1950, the plant was renamed for former NYSEG Vice President William B. Goudey. During its operation, the Goudey Power Station consisted of three coal-fired boilers, which provided steam to two turbine generators with a generating capacity of 119 megawatts.[1]

In 1999, AES Corporation purchased Goudey Station along with five other NYSEG generating facilities, and the Goudey plant was renamed AES Westover. The cost was US$953 million. The other stations included in the deal were AES Somerset, AES Cayuga, AES Greenidge, AES Hickling, and AES Jennison.[2]

In March 2011, AES Westover said it would retire its last operating unit, Unit 8, in 2012.[3]

AES Westover closed in 2012, due to high operating costs and competition from cheaper sources of electricity.[3]

The following table gives more info on this plant's SO2 emissions levels, as well as on whatever SO2 emissions "scrubbers" (Flue Gas Desulfurization units, or FGDs) have been installed at the plant. Each of the plant's units is listed separately, and at the bottom overall data for the plant is listed.[4][5]

Death and disease attributable to fine particle pollution from AES Westover Generation 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.[6] 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.[7]

Type of Impact Annual Incidence Valuation
Deaths 22 $160,000,000
Heart attacks 40 $4,400,000
Asthma attacks 360 $19,000
Hospital admissions 18 $420,000
Chronic bronchitis 14 $610,000,000
Asthma ER visits 14 $5,000

Emissions Reduction Technology

In December 2006, AES announced the company would install emission-reducing technology on Unit 8 of the AES Westover power station.[8] Construction on the $50-million project began in early 2007 and was completed in 2008.[8] AES installed a Selective Catalytic Reduction (SCR) system for a ninety percent reduction in nitrogen oxide (NOx) emissions.[8] A dry scrubber and fabric filter bag-house was built to reduce sulfur dioxide (SO₂) emissions by ninety-five percent.[8] AES expected mecury emissions would be reduced by ninety percent because of these additions.[8]

Babcock Power Environmental of Danvers, MA engineered and supplied the equipment used in the project.[8] Nicholson & Hall of Buffalo, NY led the construction.[8]

Battery Storage Project

On April 15, 2010, $22.3 million battery storage project at the AES Westover power station was approved by the New York Public Service Commission.[9][10] Unit 7 of the Westover station will be converted for the project, which will store 20 megawatts of energy until it is needed by the grid.[9] The project will include ten 53-foot containers, each with inverters and a direct current (DC) battery system storing 2 megawatts.[9] The battery storage project will be built in two phases with the first beginning in the second quarter of 2010.[9]
