North Omaha Coal Power Plant: Nebraska's 644.7 MW Facility

North Omaha is a coal-fired power plant located in Nebraska, United States, with a capacity of 644.7 MW. Owned and operated by Omaha Public Power District, the facility plays a key role in supplying electricity to the Omaha metropolitan area and surrounding regions. As a coal plant, it is subject to federal environmental regulations under the Clean Air Act. The plant's technical specifications indicate it uses coal as its primary fuel, with a capacity that places it in the medium-to-large scale for US coal plants. The facility must comply with EPA programs such as the Acid Rain Program and Cross-State Air Pollution Rule (CSAPR) to control SO2 and NOx emissions. Environmentally, the plant's coal combustion results in CO2, SO2, NOx, and particulate emissions. Its location near a populated area means it has local air quality implications, and it may be subject to state implementation plans for NAAQS compliance. The plant's operational status indicates it continues to provide baseload power, though coal plants face increasing regulatory and economic pressures from natural gas and renewables.

The North Omaha plant's coal combustion produces significant CO2 emissions, contributing to climate change, as well as SO2 and NOx that can affect local air quality. Its proximity to Omaha means emissions may impact a populated area, requiring compliance with NAAQS. The plant's age and technology (likely subcritical) result in lower efficiency and higher emissions per MWh compared to modern plants. Regulatory programs like the Acid Rain Program and CSAPR aim to reduce these pollutants.
