Weather peril exposure
WINDY FLATS WIND PROJECT is a 262 MW wind power plant in Klickitat County, WA, operated by WINDY FLATS PARTNERS LLC, commissioned in 2009. Klickitat County carries moderate modeled catastrophe exposure in the FEMA National Risk Index, scoring 2.4 of 5 at the 36th national percentile. Wildfire is the leading peril, rated Relatively High by FEMA at the 100th percentile.
The Bywatts loss layer is calibrated to solar PV hardware, so it is not applied to a wind plant. The ratings below are the FEMA National Risk Index county hazard ratings for this location.
