Susquehanna Steam Electric Station.
~3 min read · Ch. 1 of 7
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.
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.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.
