McClellan (AR) Gas Power Plant | Arkansas, United States

McClellan (AR) is a gas-fired power generation facility located in Arkansas, United States, with a capacity of 136 megawatts. Owned and operated by Arkansas Electric Coop Corp, the plant plays a role in supplying electricity to the local and regional power grid. As a gas power plant, it benefits from the operational flexibility and lower emissions profile compared to coal-fired alternatives. The facility operates under the regulatory oversight of the US Environmental Protection Agency (EPA), including the Clean Air Act (CAA) and its associated programs such as the National Ambient Air Quality Standards (NAAQS), the Acid Rain Program, and the Cross-State Air Pollution Rule (CSAPR). These regulations govern emissions of sulfur dioxide (SO2), nitrogen oxides (NOx), and other pollutants, ensuring compliance with federal air quality standards. The plant's gas-fired technology typically employs combined cycle or simple cycle configurations, with modern units achieving higher efficiency and lower emissions. McClellan (AR) contributes to the energy mix of Arkansas, supporting the state's electricity demand. Its operational status as an active facility underscores its role in maintaining grid reliability. The plant's environmental footprint is influenced by its fuel type and capacity, with natural gas combustion producing lower CO2 emissions per megawatt-hour compared to coal, aligning with broader trends toward cleaner energy generation in the United States.

The plant's gas-fired operation results in lower CO2, SO2, and NOx emissions compared to coal-fired plants, contributing to improved local air quality. Its location in Arkansas, a state with a mix of energy sources, places it within a regulatory environment that enforces emission limits under the Clean Air Act. The 136 MW capacity indicates a moderate scale, with potential impacts on nearby communities depending on stack height and dispersion patterns.
