YALE, a 134 MW Hydro power plant in Cowlitz County, Washington. Operated by PACIFICORP, commissioned 1953.
How YALE compares
With 134 MW of capacity, YALE ranks 44th among the 126 operating power plants Bywatts maps in Washington and 20th of the 65 operating Hydro plants in the state. It accounts for about 0.6% of Washington's operating Hydro capacity and 0.4% of all operating capacity in the state. Nationally it is the 136th-largest of the 1,243 operating Hydro plants in the database. Commissioned in 1953, it is older than 80% of the 125 operating Washington plants with a recorded commissioning year. Its operator, PACIFICORP, runs 7 operating plants in Washington totaling 1,484 MW. It shares Cowlitz County with 5 other operating plants, including MINT FARM GENERATING STATION and MERWIN.
EIA-860 lists 2 generators at the site with 134 MW of nameplate capacity, all conventional hydroelectric technology. Net generation was 488 GWh in 2024 (a 41% capacity factor), down 7% from 2022.
Grid neighborhood
The nearest named substation is CHELATCHIE (115 kV), about 3.7 miles away; the closest transmission line found within 10 miles is a 115 kV line owned by PACIFICORP, under 0.1 miles away. Another 3 operating power plants totaling 448 MW sit within 25 miles; the largest is SWIFT 1 (240 MW, Hydro). Within 50 miles are 2 mapped data centers; the nearest is PTOR1 in Portland, about 34.7 miles away.

Weather peril exposure
YALE is a 134 MW hydro power plant in Cowlitz County, WA, operated by PACIFICORP, commissioned in 1953. Cowlitz County carries elevated modeled catastrophe exposure in the FEMA National Risk Index, scoring 2.6 of 5 at the 40th national percentile. Coastal flooding is the leading peril, rated Relatively Low 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.

| Peril | FEMA rating | National percentile | Peril score | Events per year |
|---|---|---|---|---|
| Coastal flooding | Relatively Low | 98th | 4.9 of 5 | 1.6 |
| Earthquake | Relatively Moderate | 97th | 4.9 of 5 | 0.02 |
| Riverine flooding | Relatively Moderate | 87th | 4.5 of 5 | 0.75 |
| Heat wave | Relatively Moderate | 66th | 3.6 of 5 | 5.0 |
| Strong wind | Relatively Low | 39th | 2.5 of 5 | 0.04 |
| Wildfire | Very Low | 35th | 2.4 of 5 | <0.01 |
| Winter weather | Relatively Low | 19th | 1.8 of 5 | 21.1 |
| Ice storm | Relatively Low | 15th | 1.6 of 5 | 0.33 |
| Hail | Very Low | 11th | 1.4 of 5 | 0.05 |
