LOWER SNAKE RIVER WIND ENERGY PROJECT, a 342 MW Wind power plant in Garfield County, Washington. Operated by PUGET SOUND ENERGY INC, commissioned 2012.
How LOWER SNAKE RIVER WIND ENERGY PROJECT compares
With 342 MW of capacity, LOWER SNAKE RIVER WIND ENERGY PROJECT ranks 19th among the 126 operating power plants Bywatts maps in Washington and is the largest of the 20 operating Wind plants in the state. It accounts for about 12% of Washington's operating Wind capacity and 1.1% of all operating capacity in the state. Nationally it is the 7th-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. Its operator, PUGET SOUND ENERGY INC, runs 17 operating plants in Washington totaling 2,943 MW.
EIA-860 lists 1 generator at the site with 343 MW of nameplate capacity, all onshore wind turbine technology. Net generation was 865 GWh in 2024 (a 29% capacity factor), up 14% from 2022.

Weather peril exposure
LOWER SNAKE RIVER WIND ENERGY PROJECT is a 342 MW wind power plant in Garfield County, WA, operated by PUGET SOUND ENERGY INC, commissioned in 2012. Garfield County carries low modeled catastrophe exposure in the FEMA National Risk Index, scoring 1.4 of 5 at the 10th national percentile. Riverine flooding is the leading peril, rated Very Low by FEMA at the 97th 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.
Garfield County hazard ratings
| Peril | FEMA rating | National percentile | Peril score | Events per year |
|---|---|---|---|---|
| Riverine flooding | Very Low | 97th | 4.9 of 5 | 0.14 |
| Wildfire | Relatively Low | 92nd | 4.7 of 5 | <0.01 |
| Heat wave | Very Low | 63rd | 3.5 of 5 | 4.2 |
| Earthquake | Very Low | 57th | 3.3 of 5 | <0.01 |
| Strong wind | Very Low | 19th | 1.8 of 5 | 0.22 |
| Ice storm | Very Low | 14th | 1.5 of 5 | 0.22 |
| Hail | Very Low | 9th | 1.4 of 5 | 0.36 |
| Winter weather | Very Low | 5th | 1.2 of 5 | 10.8 |
| Tornado | Very Low | 5th | 1.2 of 5 | 0.02 |
| Lightning | Very Low | 5th | 1.2 of 5 | 14.3 |
