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.

Retirement plans
In November 2020, Wisconsin Energy said the coal plant will be retired by 2023-2024, and replaced by a combination of solar, wind, batteries, and gas power. The company said closing the aging South Oak Creek coal plant could save $50 million a year in operational and maintenance costs.[6][7]
As of June 2023, two units were slated for retirement in May 2024 and two units were slated for retirement in May 2025.[8]
In August 2023, it was reported that the WEC Energy Group wouldn't rule out delaying retirement dates at South Oak Creek Plant to help power a US$1 billion planned Microsoft data center. WEC executives reportedly said that the energy-intensive data center was "expected to factor into the company's five-year plan."[9]

Toxins
The South Oak Creek coal plant is the single largest source of toxic metals dumped into Lake Michigan, according to a September 2020 Chicago Tribune analysis of federal data.[10]
Death and disease attributable to fine particle pollution from South Oak Creek 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.[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]
Table 1: Death and disease attributable to fine particle pollution from the South Oak Creek Plant
| Type of Impact | Annual Incidence | Valuation |
|---|---|---|
| Deaths | 44 | $320,000,000 |
| Heart attacks | 70 | $7,600,000 |
| Asthma attacks | 730 | $38,000 |
| Hospital admissions | 33 | $750,000 |
| Chronic bronchitis | 27 | $1,200,000 |
| Asthma ER visits | 45 | $16,000 |
