PALOUSE, a 105 MW Wind power plant in Whitman County, Washington. Operated by PALOUSE WIND LLC, commissioned 2012.
How PALOUSE compares
With 105 MW of capacity, PALOUSE ranks 47th among the 126 operating power plants Bywatts maps in Washington and 11th of the 20 operating Wind plants in the state. It accounts for about 3.7% of Washington's operating Wind capacity and 0.3% of all operating capacity in the state. Nationally it is the 210th-largest of the 708 operating Wind plants in the database. Commissioned in 2012, it is newer than 96% of the 125 operating Washington plants with a recorded commissioning year. It shares Whitman County with 3 other operating plants, including LOWER GRANITE and GRIMES WAY.
EIA-860 lists 1 generator at the site with 105 MW of nameplate capacity, all onshore wind turbine technology. Net generation was 326 GWh in 2024 (a 35% capacity factor), up 3% from 2022.

Weather peril exposure
PALOUSE is a 105 MW wind power plant in Whitman County, WA, operated by PALOUSE WIND LLC, commissioned in 2012. Whitman County carries low modeled catastrophe exposure in the FEMA National Risk Index, scoring 1.0 of 5 at the 1st national percentile. Riverine flooding is the leading peril, rated Relatively Low by FEMA at the 66th percentile.
The Bywatts loss layer is calibrated to solar PV hardware, so it is not applied to a wind plant. The ratings below are the FEMA National Risk Index county hazard ratings for this location.
Whitman County hazard ratings
| Peril | FEMA rating | National percentile | Peril score | Events per year |
|---|---|---|---|---|
| Riverine flooding | Relatively Low | 66th | 3.6 of 5 | 0.93 |
| Wildfire | Relatively Low | 63rd | 3.5 of 5 | <0.01 |
| Heat wave | Relatively Low | 61st | 3.4 of 5 | 4.2 |
| Earthquake | Very Low | 53rd | 3.1 of 5 | <0.01 |
| Strong wind | Relatively Low | 12th | 1.5 of 5 | 0.26 |

Perils not assessed in Whitman 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 |
