ANDERSON, a 169 MW Natural Gas power plant in Madison County, Indiana. Operated by INDIANA MUNICIPAL POWER AGENCY, commissioned 1992.

How ANDERSON compares

With 169 MW of capacity, ANDERSON ranks 28th among the 77 operating power plants Bywatts maps in Indiana and 11th of the 16 operating Natural Gas plants in the state. It accounts for about 2.9% of Indiana's operating Natural Gas capacity and 0.7% of all operating capacity in the state. Nationally it is the 578th-largest of the 1,185 operating Natural Gas plants in the database. Commissioned in 1992, it is older than 57% of the 73 operating Indiana plants with a recorded commissioning year. Its operator, INDIANA MUNICIPAL POWER AGENCY, runs 2 operating plants in Indiana totaling 252 MW.

EIA-860 lists 3 generators at the site with 169 MW of nameplate capacity, all natural gas fired combustion turbine technology. Net generation was 1,014 GWh in 2024 (a 68% capacity factor). Its generators came online between 1992 and 2004.

Weather peril exposure

ANDERSON is a 169 MW natural gas power plant in Madison County, IN, operated by INDIANA MUNICIPAL POWER AGENCY, commissioned in 1992. Madison County carries elevated modeled catastrophe exposure in the FEMA National Risk Index, scoring 3.2 of 5 at the 55th national percentile. Heat wave is the leading peril, rated Relatively Low by FEMA at the 84th percentile.

The Bywatts loss layer is calibrated to solar PV hardware, so it is not applied to a natural gas plant. The ratings below are the FEMA National Risk Index county hazard ratings for this location.
