Site description

A.B. Brown Generating Station is a 700-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 CenterPoint Energy according to S&P Global. The company is planning to build two natural gas combustion turbines with a combined capacity of 460-MW at the A.B. Brown power plant site to replace its two current coal-fired units. The station operates three units regulated under the CCR rule: Landfill, Sedimentation Pond and Ash Pond. 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.
