Weather peril exposure
JAMES H MILLER JR is a 2,822 MW coal power plant in Jefferson County, AL, operated by ALABAMA POWER CO, commissioned in 1978. Jefferson County carries low modeled catastrophe exposure in the FEMA National Risk Index, scoring 1.4 of 5 at the 11th national percentile. Tornado is the leading peril, rated Very High by FEMA at the 90th 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.
