Susquehanna Steam Electric Station

• 1. Plant Origins And Ownership

  ›

  The Susquehanna Steam Electric Station began operations in 1983 near the Susquehanna River in Salem Township, Luzerne County. Bechtel Power Corporation of Reston, Virginia served as the prime builder for this massive facility. Harrisburg-based Allegheny Electric Cooperative purchased a 10% stake in the plant back in 1977. PPL operated the station until June 2015 when Talen Energy emerged from its competitive supply business. Operations now fall under Susquehanna Station Nuclear, which holds a 90% ownership share. Approximately 900 employees work directly on site while additional support staff remain based in Allentown.

• 2. Reactor Technology And Output

  ›

  Two General Electric boiling water reactors sit within a Mark II containment building at the facility. The combined capacity reaches 2.5 gigawatts capable of powering more than two million homes annually. Annual generation figures show consistent output hovering around 18 to 20 billion kilowatt-hours over recent years. Data tables reveal monthly production fluctuations with peaks often exceeding 1.9 million megawatt-hours per month. Unit 1 and Unit 2 function independently yet contribute equally to the total grid supply. This configuration allows the plant to maintain steady electricity delivery throughout seasonal demand shifts.

• 3. The Data Center Partnership

  ›

  Cumulus Data developed a campus directly connected to the power plant as a subsidiary of Talen Energy. Phase one construction finished on the 17th of January 2023 after extensive development efforts. Amazon Web Services purchased the entire campus for 650 million dollars on the 4th of March 2024. The transaction ensures the data center receives direct power from the adjacent nuclear station. This arrangement creates a unique symbiotic relationship between energy generation and digital infrastructure storage. The physical proximity reduces transmission losses while providing stable cooling solutions for server operations.

• 4. Regulatory Extensions And Licensing

  ›

  The Nuclear Regulatory Commission extended operation licenses in November 2009 for an additional twenty years. Unit 1 received specific licensing through 2042 while Unit 2 extends further to 2044. Additional license extensions have been granted since that initial decision to keep reactors running. These regulatory approvals allow the facility to continue generating electricity well into the next decade. The NRC reviews safety protocols and operational history before granting each renewal period. Such decisions reflect confidence in the aging infrastructure despite decades of continuous service.

• 5. Historical Incidents And Safety

  ›

  An electrical fire erupted at a switch box controlling cooling water supply during the plants first emergency in 1982. No injuries occurred following that incident though it disrupted normal system functions. Roughly 10,000 gallons of mildly radioactive water spilled after a gasket failed in 1985 within Unit 1 turbine building. Filtering system failure caused the spill but no radiation escaped the building to the public. Personnel remained uncontaminated as a result of this specific mechanical breakdown. These events highlight the importance of rigorous maintenance schedules for critical safety components.

• 6. Abandoned Bell Bend Project

  ›

  PPL filed an application with the U.S. Nuclear Regulatory Commission in 2008 to build a new plant near Berwick. The proposed Bell Bend Nuclear Power Plant would have utilized French-German EPR pressurized water reactor technology. Talen Energy formally requested withdrawal on the 30th of August 2016 and the NRC accepted it the 22nd of September 2016. This cancellation ended plans for a unit with 1.6 gigawatts net electric nameplate capacity. Unlike existing boiling water reactors, the EPR design offered higher per-reactor output potential. The project failure marked a significant shift in regional nuclear expansion strategies.

• 7. Seismic Risk And Population Zones

  ›

  The NRC estimated annual earthquake risk at one in 76,923 based on a study published in August 2010. Emergency planning zones define two distinct radii around the facility for public safety protocols. A plume exposure pathway zone covers areas primarily concerned with airborne radioactive contamination inhalation risks. An ingestion pathway zone extends about ten miles focusing on food and liquid consumption hazards. Census data from 2010 showed 54,686 people living within five miles of the station. Scranton sits thirty-three miles away while Wilkes-Barre remains eighteen miles from the center point.
