FREDONIA, a 376 MW Natural Gas power plant in Skagit County, Washington. Operated by PUGET SOUND ENERGY INC, commissioned 1984.
How FREDONIA compares
With 376 MW of capacity, FREDONIA ranks 18th among the 126 operating power plants Bywatts maps in Washington and 3rd of the 17 operating Natural Gas plants in the state. It accounts for about 9.4% of Washington's operating Natural Gas capacity and 1.2% of all operating capacity in the state. Nationally it is the 395th-largest of the 1,185 operating Natural Gas plants in the database. Commissioned in 1984, it is older than 52% 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. It shares Skagit County with 3 other operating plants, including MARCH POINT COGENERATION and LOWER BAKER.
EIA-860 lists 4 generators at the site with 376 MW of nameplate capacity, all natural gas fired combustion turbine technology. Net generation was 554 GWh in 2024 (a 17% capacity factor), about 2 times its 2022 output. Its generators came online between 1984 and 2001.

Weather peril exposure
FREDONIA is a 376 MW natural gas power plant in Skagit County, WA, operated by PUGET SOUND ENERGY INC, commissioned in 1984. Skagit County carries elevated modeled catastrophe exposure in the FEMA National Risk Index, scoring 2.9 of 5 at the 48th national percentile. Coastal flooding is the leading peril, rated Relatively High by FEMA at the 99th percentile.
The Bywatts loss layer is calibrated to solar PV hardware, so it is not applied to a natural gas plant. The ratings below are the FEMA National Risk Index county hazard ratings for this location.
Skagit County hazard ratings
| Peril | FEMA rating | National percentile | Peril score | Events per year |
|---|---|---|---|---|
| Coastal flooding | Relatively High | 99th | 5.0 of 5 | 3.4 |
| Earthquake | Relatively Moderate | 96th | 4.8 of 5 | 0.04 |
| Riverine flooding | Relatively Moderate | 78th | 4.1 of 5 | 0.32 |
| Heat wave | Relatively Low | 49th | 2.9 of 5 | 2.4 |
| Wildfire | Very Low | 30th | 2.2 of 5 | <0.01 |
| Winter weather | Relatively Moderate | 29th | 2.1 of 5 | 37.1 |
| Ice storm | Relatively High | 29th | 2.1 of 5 | 0.45 |
| Tornado | Very Low | 3rd | 1.1 of 5 | 0.02 |
| Lightning | Relatively Low | 3rd | 1.1 of 5 | 7.3 |
