Madison Gas Power Plant: 692 MW Facility in Indiana, United States

Madison is a gas-fired power generation facility located in Indiana, United States, with a capacity of 692 megawatts (MW). Owned and operated by Duke Energy Indiana LLC, the plant is currently operational and plays a role in meeting regional electricity demand. Gas-fired plants like Madison are a common component of the U.S. power generation mix, offering flexibility and lower emissions compared to coal. The plant operates under the regulatory framework of the U.S. Environmental Protection Agency (EPA), including the Clean Air Act (CAA) and associated programs such as 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. As a gas-fired plant, Madison likely employs combined cycle or simple cycle technology, which influences its efficiency and environmental footprint. Madison's capacity of 692 MW places it in the medium-to-large scale for gas-fired plants in the United States. Its location in Indiana, a state with a diverse industrial base, means the plant supports both residential and commercial power needs. The facility's operational status and ownership by a major utility underscore its significance in the regional energy landscape.

Madison, as a gas-fired power plant, has a lower carbon footprint compared to coal-fired plants but still emits CO2, NOx, and other pollutants. Its location in Indiana, a state with mixed industrial and agricultural land use, means the plant's emissions may affect local air quality. The facility's age and technology (subcritical vs. supercritical vs. Modern gas plants often incorporate combined cycle technology for higher efficiency. Proximity to populated areas could influence local environmental impact.
