Weather peril exposure
ARVAH B HOPKINS is a 696 MW natural gas power plant in Leon County, FL, operated by CITY OF TALLAHASSEE - (FL), commissioned in 1977. Leon County carries elevated modeled catastrophe exposure in the FEMA National Risk Index, scoring 3.2 of 5 at the 54th national percentile. Hurricane is the leading peril, rated Relatively High by FEMA at the 92nd 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.
