Weather peril exposure
JEFFERS WIND FARM is a 50 MW wind power plant in Cottonwood County, MN, operated by NRG, commissioned in 2008. Cottonwood County carries moderate modeled catastrophe exposure in the FEMA National Risk Index, scoring 2.4 of 5 at the 35th national percentile. Winter weather is the leading peril, rated Relatively Moderate by FEMA at the 96th 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.
