Edgewater Coal Power Plant | United States Power Generation Facility

Edgewater is a coal-fired power plant located in the United States, operated by Wisconsin Power & Light Co. With a capacity of 413.7 MW, it is a medium-scale facility within the US coal power sector, contributing to the region's electricity supply. The plant operates under the regulatory framework of the US Environmental Protection Agency, including the Clean Air Act, National Ambient Air Quality Standards (NAAQS), and the Acid Rain Program. As a coal-fired facility, it is subject to emissions limits for sulfur dioxide (SO2), nitrogen oxides (NOx), and particulate matter, and must comply with the Cross-State Air Pollution Rule (CSAPR) for regional air quality. Edgewater plays a role in maintaining grid reliability and supporting local energy demand. Its operational status as an active coal plant reflects its continued importance in the energy mix, though the sector faces increasing environmental scrutiny and transition toward cleaner sources.

As a coal-fired power plant, Edgewater's environmental context includes significant CO2, SO2, and NOx emissions, which contribute to local and regional air quality concerns. The plant's location near populated areas may increase exposure to pollutants. Its age and subcritical technology (typical for older coal plants) result in lower efficiency and higher emissions per MWh compared to modern supercritical or combined-cycle plants. The facility must comply with stringent US EPA regulations, including the Acid Rain Program and CSAPR, which cap SO2 and NOx emissions.
