Sheldon Station is a 228.7-megawatt (MW) coal-fired power station owned and operated by Nebraska Public Power District near Hallam, Nebraska.
- Owner: Nebraska Public Power District
- Parent Company: State of Nebraska
- Plant Nameplate Capacity: 228.7 MW (Megawatts)
- Units and In-Service Dates: Unit 1: 108.8 MW (1961), Unit 2: 119.9 MW (1965)
- Location: 4500 West Pella Rd., Hallam, NE 68368
- GPS Coordinates: 40.552055, -96.783233
- Technology: Subcritical
- Coal type: Sub-Bituminous

- Coal Source: Belle Ayr Mine (Bluegrass Commodities)
- Number of Employees:
- Unit Conversions: Unit 2 was planned for conversion to hydrogen. In 2020 those plans were cancelled.
- Unit Retirements:
Unit 2 (120 MW) was planned for conversion to run on hydrogen by 2019.
In 2020 the conversion plans were cancelled because the producer of the hydrogen found other buyers for the byproduct.

Death and disease attributable to fine particle pollution from Sheldon 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. 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.

Coal Ash Waste and Water Contamination
In August 2010 a study released by the Environmental Integrity Project, the Sierra Club and Earthjustice reported that Nebraska, along with 34 states, had significant groundwater contamination from coal ash that is not currently regulated by the Environmental Protection Agency (EPA). The report, in an attempt to pressure the EPA to regulate coal ash, noted that most states do not monitor drinking water contamination levels near waste disposal sites. The report mentioned Nebraska based Sheldon Station as having groundwater contamination due to coal ash waste.
