Weather peril exposure
PRAIRIE STAR WIND FARM is a 101 MW wind power plant in Mower County, MN, operated by HIGH PRAIRIE WIND FARM II LLC, commissioned in 2007. Mower County carries high modeled catastrophe exposure in the FEMA National Risk Index, scoring 3.9 of 5 at the 73rd national percentile. Tornado is the leading peril, rated Relatively Moderate by FEMA at the 89th 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.
