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.

Unit Retirement and Conversion to Gas
In November 2020, AEP agreed to cease coal operations at the plant in 2028[7] and announced that the plant would be converted to run on gas in 2028 and operate through 2037.[8] 2023 SWEPCO Integrated Resource Plan mentions potential gas conversion of Unit 1. [9] As of June 2024, there have not been any updates about the coal-to-gas conversion of Unit 1. Form EIA-860M released by the U.S. Energy Information Administration in May 2024, mentions retirement of the coal-fire Unit 1 in 2028.[10]
Unit 2 closure
AEP announced in June 2011 that they were slating to close Unit 2 (558.0 MW) by Dec. 31, 2014, while Units 1 and 3 (1,116 MW) would continue to operate with scrubber retrofits.[11][12]
Unit 2 was retired in April 2016.[13][14]
Proposed coal plant closure
On June 9, 2011, AEP announced that, based on impending EPA regulations as proposed, AEP’s compliance plan would retire nearly 6,000 megawatts (MW) of coal-fueled power generation; upgrade or install new advanced emissions reduction equipment on another 10,100 MW; refuel 1,070 MW of coal generation as 932 MW of natural gas capacity; and build 1,220 MW of natural gas-fueled generation. The cost of AEP’s compliance plan could range from $6 billion to $8 billion in capital investment through the end of the decade. AEP’s current plan for compliance with the rules as proposed includes permanently retiring five of its coal-fueled power plants.[15]
In addition, six other plants which will reduce their power output:[16]
- Big Sandy Plant, Louisa, Ky. - Units 1 and 2 (1,078 MW) retired by Dec. 31, 2014; Big Sandy Unit 1 would be rebuilt as a 640-MW natural gas plant by Dec. 31, 2015;
- Clinch River Plant, Cleveland, Va. - Unit 3 (235 MW) retired by Dec. 31, 2014; Units 1 and 2 (470 MW total) would be refueled with natural gas with a capacity of 422 MW by Dec. 31, 2014;
- Conesville Power Plant, Conesville, Ohio - Unit 3 (165 MW) retired by Dec. 31, 2012; Units 5 and 6 (800 MW total) would continue operating with retrofits;
- Muskingum River Plant, Beverly, Ohio - Units 1-4 (840 MW) retired by Dec. 31, 2014; Muskingum River Unit 5 (600 MW) may be refueled with natural gas with a capacity of 510 MW by Dec. 31, 2014, depending on regulatory treatment in Ohio;
- Tanners Creek Plant, Lawrenceburg, Indiana - Units 1, 2 and 3 (495 MW) retired by Dec. 31, 2014; Unit 4 (500 MW) would continue to operate with retrofits; and
- Welsh Power Plant, Pittsburg, Texas - Unit 2 (558 MW) retired by Dec. 31, 2014; Units 1 and 3 (1,116 MW) would continue to operate with retrofits.
Death and disease attributable to fine particle pollution from Welsh Power 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.[17] 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.[18]
Table 1: Death and disease attributable to fine particle pollution from Welsh Power Plant
| Type of Impact | Annual Incidence | Valuation |
|---|---|---|
| Deaths | 37 | $270,000,000 |
| Heart attacks | 56 | $6,100,000 |
| Asthma attacks | 640 | $33,000 |
| Hospital admissions | 27 | $630,000 |
| Chronic bronchitis | 23 | $10,000,000 |
| Asthma ER visits | 40 | $15,000 |

Welsh ranked 53rd 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.[19] The data came from the EPA's Toxics Release Inventory (TRI) for 2006, the most recent year available.[20]
Welsh Power Plant ranked number 53 on the list, with 562,064 pounds of coal combustion waste released to surface impoundments in 2006.[19]
