Weather peril exposure
WEST END DAM HYDROELECTRIC PROJECT is a 4 MW hydro power plant in Jefferson County, NY, operated by NORTHBROOK CARTHAGE LLC, commissioned in 1985. Jefferson County carries low modeled catastrophe exposure in the FEMA National Risk Index, scoring 1.1 of 5 at the 1st national percentile. Ice storm is the leading peril, rated Relatively Moderate by FEMA at the 73rd percentile.
The Bywatts loss layer is calibrated to solar PV hardware, so it is not applied to a hydro plant. The ratings below are the FEMA National Risk Index county hazard ratings for this location.
