Weather peril exposure
TIGER CREEK is a 58 MW hydro power plant in Amador County, CA, operated by PACIFIC GAS & ELECTRIC CO, commissioned in 1931. Amador County carries low modeled catastrophe exposure in the FEMA National Risk Index, scoring 1.6 of 5 at the 15th national percentile. Wildfire is the leading peril, rated Relatively High by FEMA at the 98th 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.

|---|---|
| Hurricane | FEMA rating is "Not Applicable" for this county |
| Coastal flooding | FEMA rating is "Not Applicable" for this county |
| Ice storm | FEMA rating is "Not Applicable" for this county |
