How MEADWESTVACO EVADALE compares
With 58 MW of capacity, MEADWESTVACO EVADALE ranks 213th among the 307 operating power plants Bywatts maps in Texas and is the largest of the 6 operating Biomass plants in the state. It accounts for about 44% of Texas's operating Biomass capacity and under 0.1% of all operating capacity in the state. Nationally it is the 64th-largest of the 350 operating Biomass plants in the database. Commissioned in 1954, it is older than 93% of the 303 operating Texas plants with a recorded commissioning year. It shares Jasper County with 2 other operating plants, SAM RAYBURN and ROBERT D WILLIS.
EIA-860 lists 3 generators at the site with 58 MW of nameplate capacity, all wood/wood waste biomass technology. Net generation was 415 GWh in 2024 (an 82% capacity factor), up 14% from 2022. Its generators came online between 1954 and 1986.

Weather peril exposure
MEADWESTVACO EVADALE is a 58 MW biomass power plant in Jasper County, TX, operated by MEADWESTVACO CORP, commissioned in 1954. Jasper County carries high modeled catastrophe exposure in the FEMA National Risk Index, scoring 4.0 of 5 at the 74th national percentile. Hurricane is the leading peril, rated Relatively Moderate by FEMA at the 91st 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.
