DILLARD COMPLEX, a 52 MW Biomass power plant in Douglas County, Oregon. Operated by ROSEBURG FOREST PRODUCTS CO, commissioned 1955.
How DILLARD COMPLEX compares
With 52 MW of capacity, DILLARD COMPLEX ranks 39th among the 130 operating power plants Bywatts maps in Oregon and 2nd of the 12 operating Biomass plants in the state. It accounts for about 22% of Oregon's operating Biomass capacity and 0.3% of all operating capacity in the state. Nationally it is the 73rd-largest of the 350 operating Biomass plants in the database. Commissioned in 1955, it is older than 79% of the 128 operating Oregon plants with a recorded commissioning year. It shares Douglas County with 11 other operating plants, including TOKETEE FALLS and LEMOLO 2.
EIA-860 lists 6 generators at the site with 52 MW of nameplate capacity, all wood/wood waste biomass technology.

Weather peril exposure
DILLARD COMPLEX is a 52 MW biomass power plant in Douglas County, OR, operated by ROSEBURG FOREST PRODUCTS CO, commissioned in 1955. Douglas County carries low modeled catastrophe exposure in the FEMA National Risk Index, scoring 1.6 of 5 at the 15th national percentile. Wildfire is the leading peril, rated Relatively High by FEMA at the 96th 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.
