Weather peril exposure
ARAPAHOE is a retired 153 MW coal power plant in Denver County, CO, formerly operated by PUBLIC SERVICE CO OF COLORADO. Denver County carries critical modeled catastrophe exposure in the FEMA National Risk Index, scoring 5.0 of 5 at the 99th national percentile. Hail is the leading peril, rated Very High by FEMA at the 99th 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.
