MMSD South Shore Wastewater Biomass Power Plant, Milwaukee, Wisconsin

MMSD South Shore Wastewater is a biomass power plant located in Milwaukee, Wisconsin, United States. With a capacity of 5.1 MW, it is a small-scale facility that utilizes biogas or other biomass derived from wastewater treatment processes to generate electricity. The plant is owned and operated by the Milwaukee Metropolitan Sewerage District, a public entity responsible for regional wastewater management. The plant operates under the regulatory framework of the US EPA Clean Air Act, which sets emission standards for biomass combustion. As a biomass facility, it benefits from renewable energy incentives and may be subject to state-level renewable portfolio standards. The technology employed is typical for small-scale biomass plants, often involving internal combustion engines or turbines fueled by biogas. Environmentally, the plant contributes to reducing greenhouse gas emissions by capturing methane from wastewater treatment and converting it to energy, displacing fossil fuel use. It supports local grid stability and provides a sustainable waste management solution for the Milwaukee area. The facility's operational status is active, underscoring its role in the community's energy and environmental infrastructure.

The plant's biomass fuel source, derived from wastewater, reduces methane emissions that would otherwise be released into the atmosphere. Located in an urban area, it helps mitigate local air pollution by displacing fossil fuel combustion. The small capacity limits its overall environmental footprint, but the facility plays a key role in the circular economy by turning waste into energy.
