HYDER SOLAR, a 22 MW Solar power plant in Yuma County, Arizona. Operated by ARIZONA PUBLIC SERVICE CO, commissioned 2011.
Weather peril exposure
HYDER SOLAR is a 22 MW solar power plant in Yuma County, AZ, operated by ARIZONA PUBLIC SERVICE CO, commissioned in 2011. Yuma County carries low modeled catastrophe exposure in the FEMA National Risk Index, scoring 1.1 of 5 at the 4th national percentile. Earthquake is the leading peril, rated Relatively High by FEMA at the 97th percentile.
Yuma County hazard ratings
| Peril | FEMA rating | National percentile | Peril score | Share of modeled loss | Events per year |
|---|---|---|---|---|---|
| Earthquake | Relatively High | 97th | 4.9 of 5 | 41% | 0.09 |
| Riverine flooding | Relatively Moderate | 63rd | 3.5 of 5 | 35% | 1.3 |
| Heat wave | Relatively High | 44th | 2.8 of 5 | <1% | 15.8 |
| Wildfire | Very Low | 36th | 2.4 of 5 | 1% | <0.01 |
| Strong wind | Relatively Moderate | 19th | 1.8 of 5 | 5% | 0.33 |
| Hail | Very Low | 12th | 1.5 of 5 | 18% | 0.04 |
| Tornado | Very Low | 4th | 1.2 of 5 | 1% | 0.07 |

| Hurricane | Very Low | 1st | 1.0 of 5 | <1% | 0.02 |
Perils not assessed in Yuma 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 |
|---|---|
| Coastal flooding | FEMA rating is "Not Applicable" for this county |
| Winter weather | No building exposure reported, so no loss rate can be derived |
| Ice storm | FEMA rating is "Not Applicable" for this county |
Hail exposure and deductible structure
Hail scores 1.5 of 5, which sits in the 1% to 2% percentage deductible range carriers are quoting for that exposure. Named windstorm and severe convective wind score 1.8 of 5, indicating a 1% to 1% wind deductible. Ranges, not single figures. The final structure is set by the carrier.
Percentage hail deductible range: 1% to 2% of insured value. Wind deductible range: 1% to 1%. These are the structures commonly seen at this exposure, not an offer and not a rate.
Modeled annual loss for a 22 MW solar array
At an assumed replacement value of $0.90 per watt, or $19.8M insured, the modeled expected annual loss for a fixed tilt ground mount array in Yuma County is $2,655 a year, $121 per MW, 0.01% of insured value.
Heat is modeled as a production risk rather than a property loss: 1.3% of annual yield in this county.
Insurability signal: Standard. Earthquake carries 41% of modeled loss.
Model hail, wind and flood exposure for Yuma County in the weather risk calculator
Ratings are the FEMA National Risk Index county hazard ratings; the peril score is a Bywatts transform of the FEMA national percentile, and the modeled loss applies the Bywatts solar vulnerability layer. Full data sources and the solar vulnerability methodology are in the weather risk calculator.
Modeled estimate for screening and negotiation. Built from FEMA National Risk Index county hazard data and a solar vulnerability layer documented above. Not a quote, a binder, or actuarial advice, and not a substitute for a carrier's own model. Hazard data: FEMA National Risk Index December 2025, synced 2026-07-24. Resolution is county level, not site level. The solar vulnerability layer that turns FEMA building loss into modeled solar loss was derived by Bywatts and revised on physical reasoning. It has not been reviewed by a practising underwriter.
