Heskett Station is an operating power station of at least 88-megawatts (MW) in Mandan, Morton, North Dakota, United States with multiple units, some of which are not currently operating. It is also known as R.M. Heskett Station.

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.

Plant Retirement
In February 2019, MDU said the coal plant is scheduled for retirement in 2021.[6] As of April 2021, the MDU website listed both units for scheduled closure in March 2022.[7] The plant fired coal for the last time on February 24, 2022.[8]
Gas-Fired Generation
After the closure of the coal plant, Heskett Station continues to send power into the grid via an existing natural gas-fired unit, which was installed in 2014, and another one that is under construction. The unit is expected to become operational in 2023. Both are peaking units.[9]

Death and disease attributable to fine particle pollution from Heskett 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.[10] The study found that over 13,000 deaths and tens of thousands of cases of chronic bronchitis, acute bronchitis, asthma-related episodes and asthma-related emergency room visits, congestive heart failure, acute myocardial infarction, dysrhythmia, ischemic heart disease, chronic lung disease, peneumonia each year are attributable to fine particle pollution from U.S. coal-fired power plants. Fine particle pollution is formed from a combination of soot, acid droplets, and metals formed from sulfur dioxide, nitrogen oxide, and soot. Among those particles, the most dangerous are the smallest (smaller than 2.5 microns), 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. 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. The table below estimates the death and illness attributable to the Heskett Station. 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.[11]

| Type of Impact | Annual Incidence | Valuation |
|---|---|---|
| Deaths | 8 | $59,000,000 |
| Heart attacks | 140 | $1,400,000 |
| Asthma attacks | 140 | $7,000 |
| Hospital admissions | 6 | $140,000 |
| Chronic bronchitis | 5 | $2,200,000 |
| Asthma ER visits | 8 | $3,000 |
