Weather peril exposure
GUADALUPE GENERATING STATION is a 1,088 MW natural gas power plant in Guadalupe County, TX, operated by GUADALUPE POWER PARTNERS LP, commissioned in 2000. Guadalupe County carries high modeled catastrophe exposure in the FEMA National Risk Index, scoring 3.8 of 5 at the 70th national percentile. Riverine flooding is the leading peril, rated Relatively High by FEMA at the 82nd 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.
