Danbury Diesel Power Plant: 7.8 MW Oil-Fired Peaking Facility in Wisconsin

Danbury Diesel is a diesel power plant located in Wisconsin, United States, with a capacity of 7.8 megawatts. The facility is owned and operated by Northwestern Wisconsin Elec Co and is currently operational. The plant operates under the regulatory framework of the U.S. Environmental Protection Agency (EPA), including the Clean Air Act and associated programs such as the Acid Rain Program and the Cross-State Air Pollution Rule (CSAPR). Diesel engines are subject to emissions standards for nitrogen oxides (NOx), sulfur dioxide (SO2), and particulate matter. The relatively small capacity of 7.8 MW places it in the small-scale category for power generation. Danbury Diesel plays a role in maintaining grid reliability in northwestern Wisconsin. Its oil-fueled design allows for rapid startup and flexibility, making it suitable for meeting peak load demands. The facility's environmental footprint is managed through compliance with state and federal emissions regulations, ensuring its operation aligns with air quality standards.

As an oil-fired diesel plant, Danbury Diesel emits CO2, NOx, SO2, and particulate matter, contributing to local and regional air quality impacts. Its location in a rural area of Wisconsin may reduce direct exposure to dense populations, but emissions can still affect regional air quality. The plant's age and technology (diesel engine) are typical for peaking units, which operate less frequently than baseload plants, potentially lowering overall annual emissions. Regulatory compliance under the Clean Air Act helps mitigate environmental harm.
