Morrow Generating Plant is an operating power station of at least 558-megawatts (MW) in Purvis, Lamar, Mississippi, United States with multiple units, some of which are not currently operating. It is also known as R.D. Morrow Sr. Generating Plant.

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.

Coal Unit Retirement and Natural Gas Unit Construction
In June 2018 plant owner Cooperative Energy said plans were underway to begin decommissioning of the coal equipment at the plant before the end of 2018.[5] In January 2019 it was reported the plant was being repowered to use natural gas and expected to be in service in early 2023.[6][7]
In March 2023, the repowering of the Morrow Generating Station was complete. The cooperative announced the 558 MW natural gas-fired combined cycle plant was online and providing electricity to nearly one million people in Mississippi. The 1×1 combined cycle unit is equipped with a Siemens 9000HL combustion turbine (capable of using up to 50% of hydrogen in the fuel mix) and is paired with a steam turbine that was retrofitted from the previous coal plant operations.[8]

Death and disease attributable to fine particle pollution from Morrow Generating 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.[9] 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.[10]

| Type of Impact | Annual Incidence | Valuation |
|---|---|---|
| Deaths | 8 | $61,000,000 |
| Heart attacks | 11 | $1,200,000 |
| Asthma attacks | 140 | $7,000 |
| Hospital admissions | 6 | $140,000 |
| Chronic bronchitis | 5 | $2,200,000 |
| Asthma ER visits | 9 | $3,000 |
