A B BROWN, a partly retired 707 MW Coal power plant in Posey County, Indiana. Most of its capacity was retired, most recently in 2023, according to EIA-860.
How A B BROWN compares
EIA-860 lists 176 MW still operable at the site (natural gas fired combustion turbine), against the 707 MW recorded for it. It shares Posey County with one other operating plant, SABIC INNOVATIVE PLASTICS MT. VERNON.
Under the same EIA plant code, EIA-860 lists 2 generators at the site with 176 MW of nameplate capacity (this page's HIFLD capacity figure is 707 MW). Net generation was 49.7 GWh in 2024 (a 3.2% capacity factor), down 98% from 2022. Its generators came online between 1991 and 2002.

Weather peril exposure
A B BROWN is a partly retired 707 MW coal power plant in Posey County, IN, operated by SOUTHERN INDIANA GAS & ELEC CO. Posey County carries elevated modeled catastrophe exposure in the FEMA National Risk Index, scoring 3.2 of 5 at the 55th national percentile. Earthquake is the leading peril, rated Relatively Low by FEMA at the 94th percentile.
The Bywatts loss layer is calibrated to solar PV hardware, so it is not applied to a coal plant. The ratings below are the FEMA National Risk Index county hazard ratings for this location.
