Conemaugh Coal Power Plant | Pennsylvania, United States

Conemaugh is a coal-fired power plant located in Pennsylvania, United States, with a capacity of 1,963 MW. It is operated by KeyCon Operating LLC and is classified as a large-scale baseload facility within the US power generation sector. The plant operates under the regulatory framework of the US Environmental Protection Agency, including the Clean Air Act, National Ambient Air Quality Standards, Acid Rain Program, and Cross-State Air Pollution Rule. These regulations govern emissions of sulfur dioxide, nitrogen oxides, and particulate matter, requiring compliance through technologies such as scrubbers and selective catalytic reduction. As a coal-fired plant, Conemaugh contributes to the regional electricity supply but faces environmental challenges related to CO2 emissions and local air quality. Its proximity to populated areas in Pennsylvania underscores the importance of emission controls and ongoing regulatory oversight.

The plant's coal fuel source results in significant CO2 emissions per MWh compared to natural gas or renewables. Its location in Pennsylvania, a state with a mix of urban and rural areas, means that emissions of SOx, NOx, and particulates can affect local air quality. The plant's age and technology (subcritical or supercritical) influence its efficiency and environmental footprint. Compliance with CSAPR and Acid Rain Program requirements is critical for minimizing regional impacts.
