Weather peril exposure
ROSEVILLE ENERGY PARK is a 164 MW natural gas power plant in Placer County, CA, operated by CITY OF ROSEVILLE - (CA), commissioned in 2007. Placer County carries low modeled catastrophe exposure in the FEMA National Risk Index, scoring 1.3 of 5 at the 7th national percentile. Wildfire is the leading peril, rated Relatively High by FEMA at the 96th percentile.
The Bywatts loss layer is calibrated to solar PV hardware, so it is not applied to a natural gas plant. The ratings below are the FEMA National Risk Index county hazard ratings for this location.
Placer County hazard ratings
| Peril | FEMA rating | National percentile | Peril score | Events per year |
|---|---|---|---|---|
| Wildfire | Relatively High | 96th | 4.8 of 5 | <0.01 |
| Earthquake | Relatively Moderate | 86th | 4.5 of 5 | 0.03 |
| Riverine flooding | Relatively High | 69th | 3.8 of 5 | 1.1 |
| Heat wave | Relatively Low | 61st | 3.4 of 5 | 4.3 |
| Tornado | Very Low | 7th | 1.3 of 5 | 0.14 |
| Strong wind | Relatively Low | 3rd | 1.1 of 5 | 0.07 |
| Lightning | Relatively High | 2nd | 1.1 of 5 | 14.2 |
| Winter weather | Relatively Low | 1st | 1.0 of 5 | 27.2 |
| Hail | Very Low | 1st | 1.0 of 5 | 0.16 |
Perils not assessed in Placer County
These perils carry no usable National Risk Index figure for this county, so they are excluded from the scoring rather than scored zero. A zero would claim the peril was assessed and found benign.
| 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 |
| Ice storm | FEMA rating is "Not Applicable" for this county |
