COVANTA DELAWARE VALLEY, a 90 MW Biomass power plant in Delaware County, Pennsylvania. Operated by COVANTA DELAWARE VALLEY LP, commissioned 1991.
How COVANTA DELAWARE VALLEY compares
With 90 MW of capacity, COVANTA DELAWARE VALLEY ranks 49th among the 170 operating power plants Bywatts maps in Pennsylvania and 2nd of the 21 operating Biomass plants in the state. It accounts for about 18% of Pennsylvania's operating Biomass capacity and 0.2% of all operating capacity in the state. Nationally it is the 26th-largest of the 350 operating Biomass plants in the database. Commissioned in 1991, it is older than 57% of the 168 operating Pennsylvania plants with a recorded commissioning year. It shares Delaware County with 4 other operating plants, including EDDYSTONE GENERATING STATION and FPL ENERGY MARCUS HOOK LP.
EIA-860 lists 1 generator at the site with 90 MW of nameplate capacity, all municipal solid waste technology. Net generation was 553 GWh in 2024 (a 70% capacity factor), up 7% from 2022.

Weather peril exposure
COVANTA DELAWARE VALLEY is a 90 MW biomass power plant in Delaware County, PA, operated by COVANTA DELAWARE VALLEY LP, commissioned in 1991. Delaware County carries low modeled catastrophe exposure in the FEMA National Risk Index, scoring 1.1 of 5 at the 4th national percentile. Earthquake is the leading peril, rated Relatively Moderate by FEMA at the 75th 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.
