Somerset Generation Plant
Somerset Generation Plant, also known as the Niagara Coal Plant, was a 655.1-megawatt (MW) coal-fired power station operated by Somerset Operating Co in Barker, New York.
The undated satellite photo below shows the location of the now retired power station in Barker, NY.
- Owner: Somerset Operating Co
- Parent Company: Riesling Power owned by Beowulf Energy LLC
- Plant Nameplate Capacity: 655.1 MW (Megawatts)
- Units and In-Service Dates: Unit 1: 655.1 MW (1984)
- Location: 7725 Lake Rd., Barker, NY 14012
- GPS Coordinates: 43.356824, -78.604214
- Technology: Subcritical
- Coal type: Bituminous
- Coal Consumption:
- Coal Source: Loveridge 22 Mine (Consol), Blacksville 2 Mine (Consol)
- Number of Employees:
- Unit Retirements: Unit 1, the plant's only unit, retired in March 2020.
On November 15, 2019, the Somerset Operating Company announced plans to close the plant in 90 days. Plant owner Riesling Power LLC cited stricter state emissions rules as well as "deteriorating market conditions." The closure will mark the end of coal-fired energy generation in the state.
In 1999, AES purchased six power plants in New York (including the Somerset station) from NGE Generation, Inc. for $953 million. The other stations included in the deal were AES Westover, AES Cayuga, AES Greenidge, AES Hickling, and AES Jennison
AES filed for bankruptcy protection on December 30, 2011. A group of bondholders formed Upstate New York Power Producers to purchase AES Cayuga power station and Somerset from the bankrupt AES Energy East for US$240 million in 2012.

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.

|Total||1984||655 MW||5,226,893 MWh||3,131 tons||1.20 lb./MWh||3.20%||spray tower||1984||90%|
Death and disease attributable to fine particle pollution from AES Somerset 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. 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.
