Holsum Irish Dairy Biomass Power Plant, Wisconsin, United States

Holsum Irish Dairy is a biomass power plant located in Wisconsin, United States, with a capacity of 1 MW. The plant is owned and operated by Holsum Irish Dairy and is currently operational. As a small-scale biomass facility, it contributes to the local energy mix by converting organic materials into electricity. The plant operates under the regulatory framework of the United States Environmental Protection Agency (EPA), which sets emission standards for biomass power plants under the Clean Air Act. Biomass power plants like Holsum Irish Dairy are subject to New Source Performance Standards (NSPS) and may need to comply with state-level regulations in Wisconsin. The technology typically involves combustion of biomass feedstocks such as agricultural waste or wood chips. Holsum Irish Dairy plays a role in the local community by providing renewable energy and managing agricultural waste. Its small capacity suggests it may serve as a distributed generation source, potentially reducing transmission losses and supporting grid stability in the region. The plant's operation aligns with broader trends in the United States toward renewable energy and waste-to-energy solutions.

Biomass power plants like Holsum Irish Dairy can help reduce greenhouse gas emissions by utilizing waste materials that would otherwise decompose and release methane. However, combustion of biomass still produces CO2, SOx, and NOx, though at lower levels compared to fossil fuels. The plant's location in a rural area of Wisconsin likely minimizes direct impact on densely populated regions. Its small capacity (1 MW) limits its overall environmental footprint, but local air quality considerations remain relevant under EPA regulations.
