A.B. Brown Generating Station is a 650 MW coal and natural gas fired power plant located in Posey County, Indiana. The plant is owned by Southern Indiana Gas & Electric Co., a subsidiary of Vectren. According to a 2015 inspection report from the Indiana Department of Environmental Management, some fly ash from the plant's coal-fired units is sent by barge to Missouri for use by Holcim Cement, but the majority of ash is disposed of in on-site ash ponds. Filter cake from the plant's flue gas desulfurization process is sent to an on-site restricted waste landfill.
A.B. Brown Generating Station is among the U.S. Environmental Protection Agency's list of potential damage cases, indicating that coal ash disposal at the site has potentially polluted groundwater or surface water at levels which threaten human health and the environment.
