Unit Conversions and Retirements

In June 2014 owner Omaha Public Power District (OPPD) said it will retire three of five generating units at the 60-year-old North Omaha plant by 2016. The two remaining units will remain on coal but be retrofitted with additional emission controls, and then converted to run on natural gas by 2023. OPPD said the changes will allow the utility to be compliant with new mercury and air toxic standards adopted by the Environmental Protection Agency.

The decision over the power station grew out of stakeholder meetings for a 20-year generation plan for OPPD. The plan puts OPPD on track for having 33 percent of its retail generation load come from renewable sources by 2018 (as well as 31 percent from coal, 33 percent nuclear, and 3 percent natural gas and oil by 2018). The measure approved by the OPPD board is estimated to have minimal effect on customer rates, ranging from zero to 2 percent over a 20-year period.[10]

The plant's first three coal-fired units were retired and converted to natural gas in March to April 2016. [11][12] These units serve as peaking units during times of high demand for electricity[13]. Units 4 and 5 were scheduled to be converted to natural gas before 2024.[14]

OPPD made a recommendation at its June 2022 Board of Directors meeting to delay the retirement of North Omaha Station units 1-3 and fuel conversion of units 4 and 5 from low-sulfur coal to natural gas until Standing Bear Lake (SBLS) and Turtle Creek (TCS) power stations are ready and approved to connect to the grid at full capacity. Previously, OPPD's Board of Directors approved these changes to occur by the end of 2023. At the August 2022 monthly board meeting, OPPD’s Board of Directors voted to approve this recommendation.[13][15]

Death and disease attributable to fine particle pollution from North Omaha 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.[16] 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.[17]

Type of Impact Annual Incidence Valuation
Deaths 14 $100,000,000
Heart attacks 22 $2,400,000
Asthma attacks 240 $13,000
Hospital admissions 10 $240,000
Chronic bronchitis 9 $3,900,000
Asthma ER visits 15 $6,000
