Big Sky Dairy Digester - Biomass Power Plant in the United States

Big Sky Dairy Digester is a biomass power plant located in the United States, with coordinates 42.8656, -114.7914. The facility has a capacity of 1.6 MW and is classified as a small-scale biomass power plant. It is owned by DF-AP #1 LLC and is currently operational. The plant operates using biomass fuel, specifically dairy waste, which is converted into biogas through anaerobic digestion. This technology is common in agricultural regions for managing waste and generating renewable energy. The facility falls under the regulatory framework of the US Environmental Protection Agency (EPA), including the Clean Air Act, which sets emission standards for biomass combustion. As a small-scale renewable energy facility, Big Sky Dairy Digester contributes to local grid stability and supports sustainable waste management in the dairy industry. Its operation reduces methane emissions from manure and provides a source of clean electricity, aligning with broader state and federal renewable energy goals.

The plant's use of dairy waste as fuel reduces methane emissions from manure storage, a potent greenhouse gas. Its small capacity (1.6 MW) limits local air quality impacts, but biomass combustion still emits CO2, NOx, and particulates. The facility is likely in an agricultural area, minimizing proximity to dense populations. Regulatory oversight under the Clean Air Act ensures compliance with emission limits.
