Weather peril exposure
AMISTAD DAM & POWER is a 66 MW hydro power plant in Val Verde County, TX, operated by INTERNATIONAL BOUND & WTR COMM, commissioned in 1983. Val Verde County carries elevated modeled catastrophe exposure in the FEMA National Risk Index, scoring 3.4 of 5 at the 59th national percentile. Wildfire is the leading peril, rated Relatively Low by FEMA at the 76th 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.
