How PPL SUSQUEHANNA compares
With 2,596 MW of capacity, PPL SUSQUEHANNA is the largest of the 170 operating power plants Bywatts maps in Pennsylvania and the largest of the 5 operating Nuclear plants in the state. It accounts for about 26% of Pennsylvania's operating Nuclear capacity and 6.6% of all operating capacity in the state. Nationally it is the 5th-largest of the 55 operating Nuclear plants in the database. Commissioned in 1983, it is older than 73% of the 168 operating Pennsylvania plants with a recorded commissioning year. It shares Luzerne County with 6 other operating plants, including HAZELTON and HUNLOCK POWER STATION.
EIA-860 lists 2 generators at the site with 2,532 MW of nameplate capacity, all nuclear technology. Net generation was 19,744 GWh in 2024 (an 89% capacity factor), down 2% from 2022. Its generators came online between 1983 and 1985.

Weather peril exposure
PPL SUSQUEHANNA is a 2,596 MW nuclear power plant in Luzerne County, PA, operated by PPL SUSQUEHANNA LLC, commissioned in 1983. Luzerne County carries low modeled catastrophe exposure in the FEMA National Risk Index, scoring 1.2 of 5 at the 4th national percentile. Riverine flooding is the leading peril, rated Relatively High by FEMA at the 66th percentile.
The Bywatts loss layer is calibrated to solar PV hardware, so it is not applied to a nuclear plant. The ratings below are the FEMA National Risk Index county hazard ratings for this location.
