Weather peril exposure
ELKHORN VALLEY WIND FARM is a 101 MW wind power plant in Union County, OR, operated by TELOCASET WIND POWER PARTNERS, commissioned in 2007. Union County carries low modeled catastrophe exposure in the FEMA National Risk Index, scoring 1.3 of 5 at the 8th national percentile. Wildfire is the leading peril, rated Relatively Moderate by FEMA at the 94th 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.

| Peril | Why it is not scored |
|---|---|
| Hurricane | FEMA rating is "Not Applicable" for this county |
| Coastal flooding | FEMA rating is "Not Applicable" for this county |
