Weather peril exposure
ARCELORMITTAL INDIANA HARBOR WEST is a 152 MW natural gas power plant in Lake County, IN, operated by ARCELORMITTAL INDIANA HARBOR WEST, commissioned in 1959. Lake County carries low modeled catastrophe exposure in the FEMA National Risk Index, scoring 1.5 of 5 at the 12th national percentile. Heat wave is the leading peril, rated Relatively Moderate by FEMA at the 82nd 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.
