Weather peril exposure

GARY WORKS is a 161 MW natural gas power plant in Lake County, IN, operated by UNITED STATES STEEL-GARY, commissioned in 1997. 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.
