• On a 2,100-acre site in Salem Township, Luzerne County, Pa.
  • About seven miles northeast of Berwick, Pa.
  • About 20 miles southwest of Wilkes-Barre, Pa.


Our People

  • During normal operation, the plant nearly 1,000 full-time, local employees in operations, maintenance, engineering and technical support positions.
  • About 1,000 additional people work at the plant during refueling outages, which are scheduled for each unit every 24 months.


Clean Energy Generation

  • Energy generated is carbon-free
  • Together with Pennsylvania’s other nuclear plants, nuclear energy generated helps avoid 37 million tons of CO2 annually (equivalent to 8 million cars)
  • Susquehanna has a 94% reliability factor for power delivery
  • It generates enough carbon-free energy to power over 2 million homes



The Unit 1 reactor began commercial operation in 1983; Unit 2 in 1985.

  • The plant has two boiling water reactors made by General Electric Co.
  • Heat is produced by the splitting, or fissioning, of uranium atoms, which makes steam that drives turbine-generators to produce electricity.
  • The two units are capable of generating more than 2,600 megawatts.
  • Two 540-foot cooling towers are used to cool the water used in the plant.



  • Susquehanna Nuclear LLC owns 90 percent of the plant and operates it; Allegheny Electric Cooperative Inc. owns 10 percent.
  • Susquehanna Nuclear LLC is one of Talen Energy Corporation’s generating affiliates. Talen Energy is one of the largest competitive energy and power generation companies in the United States.
  • Allegheny Electric Cooperative, based in Harrisburg, Pa., provides power to member cooperatives in Pennsylvania and New Jersey. Allegheny purchased 10 percent of the Susquehanna plant in 1977.  Susquehanna provides approximately 60% of Allegheny’s power supply – enough for over 600,000 homes in rural Pennsylvania.
