Audrain Generating Station - 814 MW Gas Power Plant in Missouri, United States

Audrain Generating Station is a gas-fired power generation facility located in Missouri, United States. With a capacity of 814 MW, it is a large-scale plant in the U.S. power sector, contributing to the region's electricity supply. The plant is owned and operated by Union Electric Co, a major utility in the Midwest. The facility operates on natural gas, a fuel that offers lower CO2 emissions compared to coal but still requires compliance with environmental regulations. As a U.S. plant, it falls under the Clean Air Act, including the Acid Rain Program and CSAPR, which set limits on SO2, NOx, and other pollutants. The plant's technology likely includes combined-cycle gas turbines, common for modern gas plants, enhancing efficiency and reducing emissions. Audrain Generating Station plays a key role in meeting peak electricity demand in Missouri and surrounding areas. Its operational status ensures reliable power for residential, commercial, and industrial customers. The plant's location in a rural area minimizes direct population exposure, though its emissions contribute to regional air quality considerations.

The plant's gas fuel type results in lower CO2, SO2, and NOx emissions compared to coal-fired plants, but still contributes to greenhouse gas emissions. Its location in a rural area reduces direct impact on densely populated zones, but regional air quality is subject to EPA NAAQS standards. The plant's capacity of 814 MW indicates significant fuel consumption and potential environmental footprint, though modern gas technology can mitigate some impacts.
