In February 2019 it was reported that if the Georgia Public Service Commission approved Georgia Power’s plan, Plant Hammond would be taken out of service, possibly as soon as August 2019.[3] The plant had averaged only a 16 percent capacity factor since the beginning of 2012.[4]

The plant was officially decommissioned after the Georgia Public Service Commission voted on July 16, 2019 to shut the plant down.[5]

Emissions Data

  • 2006 CO2 Emissions: 4,509,401 tons
  • 2006 SO2 Emissions: 40,579 tons
  • 2006 SO2 Emissions per MWh:
  • 2006 NOx Emissions: 5,783 tons
  • 2005 Mercury Emissions: 164 lb.


According to a report on the plant by IEEFA (2015), the plant has grown increasingly expensive for ratepayers, due to both its old age and its declining use since 2007 from the increased use of natural gas in the region. The plant has averaged only a 16 percent capacity factor since the beginning of 2012. Meanwhile, the annual per-megawatt-hour (MWh) costs of generating power at Plant Hammond have increased by about two-thirds since 2010.[6]

Death and disease attributable to fine particle pollution from Hammond Steam 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.[7] 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.[8]

Type of Impact Annual Incidence Valuation
Deaths 82 $600,000,000
Heart attacks 120 $12,000,000
Asthma attacks 1,400 $72,000
Hospital admissions 58 $1,400,000
Chronic bronchitis 50 $22,000,000
Asthma ER visits 83 $31,000

Hammond ranked 43rd on list of most polluting power plants in terms of coal waste

In January 2009, Sue Sturgis of the Institute of Southern Studies compiled a list of the 100 most polluting coal plants in the United States in terms of coal combustion waste (CCW) stored in surface impoundments like the one involved in the TVA Kingston Fossil Plant coal ash spill.[9] The data came from the EPA's Toxics Release Inventory (TRI) for 2006, the most recent year available.[10]

Hammond Steam Generating Station ranked number 43 on the list, with 849,068 pounds of coal combustion waste released to surface impoundments in 2006.[9]

Legislative issues

House Bill 276, proposed by Margaret Oliver (D-Decatur), would put a 5-year moratorium on building new coal plants and eliminate the burning of Appalachian coal mined by mountaintop removal by mid-2016. The Appalachian Mountain Preservation Act would gradually prohibit Georgia coal consumers from using Central Appalachian mountaintop removal beginning in 2011. The bill is backed by environmental groups including Appalachian Voices but received strong opposition from POWER4Georgians, a coalition of 10 electric co-operatives seeking to build a $2 billion 850-megawatt supercritical coal plant in Washington County.[11][12]
