Weather peril exposure
SPENCER is a 127 MW natural gas power plant in Denton County, TX, operated by CITY OF GARLAND - (TX), commissioned in 1966. Denton County carries critical modeled catastrophe exposure in the FEMA National Risk Index, scoring 4.8 of 5 at the 95th national percentile. Hail is the leading peril, rated Very High by FEMA at the 96th 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.
