CHP is an abbreviation for Combined Heat and Power. It is a technology that produces electricity and thermal energy at high efficiencies. Coal units track this information in the Captive Use section when known.

On December 2, 2009, Exelon announced that it would retire its two coal units at Eddystone Generating Station in 2011 and 2012. Eddystone will continue to operate 820 MW of natural gas- and oil-fired generation. Exelon senior vice president Doyle Beneby said the retirement was due to "decreased power demand, over supply of natural gas and increasing operating costs," adding that "these aging units are no longer efficient enough to compete with newer resources."[3]

The two coal-burning units were retired in 2011-2012. The plant continues to operate 820 MW of natural gas- and oil-fired generation.

Accidents and Negligence

  • February 19, 1983:Two workers were severely burned when the circuit breaker on a disabled generating unit blew during repairs.[7]
  • October 5, 1983: A pill-sized radioactive pellet was dropped on the boiler room floor. According to Philadelphia Electric and the Nuclear Regulatory Commission overseeing the recovery, no one was exposed or in danger at the time of the incident.[8]
  • September 10, 1987:[9]
    • A worker cleaning a sulfur dioxide scrubber bled to death when a power washer spontaneously turned on, shooting a 6,000 pounds-per-square-inch spray of water through his leg.
    • Responding to the call for help without a stretcher or medical supplies, workers determined it would be more beneficial to attempt to remove the man from the scrubber before attempting first aid.
    • The man bled to death before he could be removed from the scrubber.

Litigation and Controversy

  • March 17, 2002[10]
    • Eddystone power plant begins discussion over $5.7 million in delinquent state taxes that had nearly bankrupted the local school district.
    • Arguments over the plant’s value assessment kept the company from paying $3.6 million to the school district, $1 million to the town of Eddystone, and $1.1 million to Delaware County.
    • While the company files appeals, the county, town, and school board authorities acknowledge they have almost no power to force payment, unlike with private property where tax-liens can be placed on the property.
    • A week later, half the payment was received while negotiations continued on the unpaid portion.[citation needed]

Death and disease attributable to fine particle pollution from Eddystone

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.[11] 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.[12]

Type of Impact Annual Incidence Valuation
Deaths 20 $140,000,000
Heart attacks 34 $3,700,000
Asthma attacks 320 $17,000
Hospital admissions 15 $360,000
Chronic bronchitis 12 $5,300,000
Asthma ER visits 13 $5,000
