- Unit Retirements: Both units are scheduled for retirement in June 2021.
The coal plant is scheduled for retirement in 2021.
According to the EIA-923 file of 2019 and February 2020 the Hoot Lake Plant did not receive or use any fuel in 2019 and 2020. Earlier retirement or idling of the plant can not be confirmed at this point.
Scheduled conversion to natural gas
In January 2013, the Minnesota PUC approved a plan to convert the plant to natural gas by 2020. In addition, Otter Tail will install pollution controls at the plant by 2015. In 2019 it was reported that the facility will not be converted but replaced by a new powerplant with a 245-megawatt natural gas combustion turbine, to be build southeast of Watertown in east central South Dakota. The facility will be known as the Astoria Station.

Death and disease attributable to fine particle pollution from Hoot Lake 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. 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.
