LONGVIEW FIBRE, a partly retired 123 MW Biomass power plant in Cowlitz County, Washington. Most of its capacity was retired, most recently in 2018, according to EIA-860.
How LONGVIEW FIBRE compares
EIA-860 lists 45 MW still operable at the site (wood/wood waste biomass), against the 123 MW recorded for it. 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 45 MW of nameplate capacity, all wood/wood waste biomass technology (this page's HIFLD capacity figure is 123 MW). Net generation was 235 GWh in 2024 (a 60% capacity factor), up 8% from 2022. Its generators came online between 1958 and 1966.
Grid neighborhood
The nearest named substation is COWLITZ (115 kV), about 1.1 miles away; the closest transmission line found within 10 miles is a 115 kV line owned by PUD NO 1 OF COWLITZ COUNTY, under 0.1 miles away. Another 6 operating power plants totaling 1,644 MW sit within 25 miles; the largest is BEAVER (611 MW, Natural Gas). Within 50 miles are 2 mapped data centers; the nearest is Digital Fortress (PTL) in Portland, about 41.8 miles away.

Weather peril exposure
LONGVIEW FIBRE is a partly retired 123 MW biomass power plant in Cowlitz County, WA, operated by LONGVIEW FIBRE CO. 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 biomass plant. The ratings below are the FEMA National Risk Index county hazard ratings for this location.

|---|---|---|---|---|
| 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 |
