Plant Idled

NRG idled the coal plant in January 2016. It has been on reserve service only since 2012.[1] EIA lists the status of all 4 units of the plant as "(OS) Out of service and NOT expected to return to service in next calendar year".[2]

Conversion or Retirement

In 2015, NRG said it plans for the Dunkirk plant to be converted to natural gas, but to allow it to continue to burn coal as a back-up fuel. The proposal is being challenged in court. According to IEEFA, New York would like to keep the plant online due to local government reliance on the property taxes that the plant generates.[3]

In November 2015, a report by the New York Independent System Operator, done with National Grid, found the Dunkirk plant could be mothballed as early as January 2016 without power disruptions, after some transmission updates. NRG is still planning on making the plant gas-fired, while critics say the money would be better spent on efficiency and transmission upgrades.[4]

However, in July 2018 NRG Energy said it will not restart its Dunkirk power plant, because the cost to reconnect the facility to the state’s electric grid prohibits reopening the retired coal-fired plant as a natural gas-fueled facility.[1]

In 2019 the city of Dunkirk received a $60,000 grant for a feasibility study to restore use of the NRG plant facilities.[5]

Death and disease attributable to fine particle pollution from Dunkirk Steam 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.[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]
