Weather peril exposure
H L CULBREATH BAYSIDE POWER STATION is a 2,294 MW natural gas power plant in Hillsborough County, FL, operated by TAMPA ELECTRIC CO, commissioned in 1965. Hillsborough County carries high modeled catastrophe exposure in the FEMA National Risk Index, scoring 3.6 of 5 at the 65th national percentile. Hurricane is the leading peril, rated Very 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.

| Peril | Why it is not scored |
|---|---|
| Winter weather | FEMA rating is "No Rating" for this county |
| Ice storm | FEMA rating is "Not Applicable" for this county |
