Marshall Energy Facility: Gas Power Plant in the United States

Marshall Energy Facility is a gas-fired power generation station located in the United States, with coordinates 37.0286° N, -88.3958° W. The plant has a capacity of 688 megawatts (MW) and is owned by the Tennessee Valley Authority (TVA), a major federal utility. It operates as a gas power plant, contributing to the regional grid. The facility utilizes natural gas as its primary fuel, a common choice for modern power generation due to lower emissions compared to coal. The 688 MW capacity places it in the medium-to-large scale range for gas plants in the U.S. The plant operates under the regulatory framework of the U.S. Environmental Protection Agency (EPA), including the Clean Air Act (CAA) and associated rules such as the Cross-State Air Pollution Rule (CSAPR) and the Acid Rain Program, which govern emissions of SOx, NOx, and other pollutants. As part of TVA's generation fleet, Marshall Energy Facility plays a key role in meeting electricity demand in the Tennessee Valley. Its gas-fired technology allows for flexible operation, supporting grid stability and integration of renewable energy sources. The plant's environmental footprint is managed through compliance with federal and state regulations, ensuring minimal impact on local air quality.

The Marshall Energy Facility operates in a region with a mix of industrial and residential areas. Natural gas combustion produces lower CO2 emissions per MWh than coal, but still contributes to greenhouse gas emissions. The plant's location near the Tennessee River may influence local water use for cooling. Proximity to populated areas requires adherence to air quality standards under the EPA's National Ambient Air Quality Standards (NAAQS) to protect public health.
