SWIFT 1, a 240 MW Hydro power plant in Skamania County, Washington. Operated by PACIFICORP, commissioned 1958.

How SWIFT 1 compares

With 240 MW of capacity, SWIFT 1 ranks 28th among the 126 operating power plants Bywatts maps in Washington and 15th of the 65 operating Hydro plants in the state. It accounts for about 1.1% of Washington's operating Hydro capacity and 0.8% of all operating capacity in the state. Nationally it is the 77th-largest of the 1,243 operating Hydro plants in the database. Commissioned in 1958, it is older than 72% of the 125 operating Washington plants with a recorded commissioning year. Its operator, PACIFICORP, runs 7 operating plants in Washington totaling 1,484 MW.

EIA-860 lists 3 generators at the site with 240 MW of nameplate capacity, all conventional hydroelectric technology. Net generation was 519 GWh in 2024 (a 25% capacity factor), down 16% from 2022.

Grid neighborhood

The nearest named substation is SWIFT 1 (230 kV), about 0.1 miles away; the closest transmission line found within 10 miles is a 230 kV line owned by PACIFICORP, under 0.1 miles away. Another 3 operating power plants totaling 342 MW sit within 25 miles; the largest is MERWIN (136 MW, Hydro). Within 50 miles are 2 mapped data centers; the nearest is PTOR1 in Portland, about 43.8 miles away.

Weather peril exposure

SWIFT 1 is a 240 MW hydro power plant in Skamania County, WA, operated by PACIFICORP, commissioned in 1958. Skamania County carries low modeled catastrophe exposure in the FEMA National Risk Index, scoring 1.6 of 5 at the 16th national percentile. Wildfire is the leading peril, rated Relatively Moderate by FEMA at the 95th 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.
