Retirement plans
In September 2016, it was reported Craig Station Unit 1, a 446 MW unit built in 1979, will be shut down by December 31, 2025.[7] Unit 2 (also 446 MW) is planned for retirement in 2026.[8]
During a media call on January 9, 2020 executives from Tri-State Generation and Transmission said that Units 2 and 3 will retire in 2030 and Unit 1 is still on schedule for retirement in 2025. Before the annoucement Units 2 and 3 were scheduled for closure in 2038 and 2044, respectively.[9][9]
In July 2020, S&P Global reported that Tri-State announced that unit 2 would close in September of 2028 instead of 2030.[10] In November 2020, the Air Quality Control Commission approved Colorado’s regional haze plan, requiring unit 3 to also close by 2028.[11]
However, in December 2020, the Colorado Air Quality Control Commission voted to reverse the plan. The about-face followed objections from utilities and the Colorado Energy Office, which was coordinating Gov. Jared Polis’ efforts to reduce greenhouse gas emissions.[12]
In December 2023, Tri-State filed an updated resource plan with the Colorado Public Utilities Commission proposing that all three units be retired by the end of 2028. Unit 3 was slated to retire in January 2028, and Unit 2 was slated to retire in September 2028.[13]

Death and disease attributable to fine particle pollution from Craig 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.[14] 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.[15]
Table 1: Death and disease attributable to fine particle pollution from Craig Station
| Type of Impact | Annual Incidence | Valuation |
|---|---|---|
| Deaths | 24 | $170,000,000 |
| Heart attacks | 36 | $400,000,000 |
| Asthma attacks | 440 | $23,000 |
| Hospital admissions | 16 | $380,000 |
| Chronic bronchitis | 16 | $6,900,000 |
| Asthma ER visits | 22 | $8,000 |
