Edwardsport Coal Power Plant: Indiana, USA Power Generation Facility

Edwardsport is a coal-fired power plant located in Indiana, United States, with a capacity of 804.5 MW. Owned by Duke Energy Indiana LLC, the facility is operational and plays a significant role in the local power grid. As a coal plant, it is part of the traditional baseload generation fleet in the region. The plant operates under the regulatory framework of the U.S. 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. The technology employed is typical for coal plants of this era, with subcritical or supercritical steam cycles. Edwardsport's environmental context involves its fuel type and emissions profile. Coal combustion produces CO2, SO2, NOx, and particulate matter. The plant's location in Indiana, a state with a mix of industrial and agricultural activities, means its operations are subject to state and federal air quality standards. The facility's capacity places it in the medium-to-large scale for coal plants in the U.S., and its operational status indicates ongoing contribution to grid reliability.

Edwardsport's coal-fired operations result in emissions of CO2, SO2, NOx, and particulate matter, which are regulated under the Clean Air Act. The plant's location in Indiana, a state with significant coal generation, means it operates within a regional air quality management framework. Proximity to populated areas may influence local air quality impacts, though specific distances are not detailed. The plant's age and technology (likely subcritical or supercritical) affect its efficiency and emission intensity.
