Scheduled Refueling and Maintenance Outage for Susquehanna Steam Electric Station Unit 1 Underway

Refueling occurs every 24 months, allowing the unit to generate reliable, always-on carbon-free power for another two years

Berwick, PA (March 30, 2022) – Susquehanna Nuclear, LLC announced today that operators at the Susquehanna Steam Electric Station (“Susquehanna”) safely disconnected the Unit 1 reactor from the electrical grid to begin its regularly scheduled refueling and maintenance outage. The unit’s outage ensures that the station continues to run safely and efficiently, generating reliable “always on” carbon-free power. Susquehanna’s Unit 2 reactor is set to continue regular operation during this time.

Both Unit 1 and 2 can run for approximately 24 months without the need to refuel. Outages are scheduled for each unit on alternating years to ensure that power continues to be generated and available while one unit is undergoing maintenance and refueling.

“While refueling Unit 1, we will also complete proactive maintenance work to keep Susquehanna generating dependable, carbon-free energy safely and efficiently to meet the needs of our stakeholders,” said Kevin Cimorelli, site vice president. “Our goal is to complete the outage on time and with zero injuries.”

Susquehanna’s employees, together with approximately 1,800 supplemental workers, are scheduled to perform approximately 10,000 maintenance activities while replacing about one-third of the unit’s fuel during the outage. These workers help boost the local economy by patronizing local restaurants, stores and lodging and supporting services throughout the community.

The Susquehanna plant, located about seven miles north of Berwick, is owned jointly by Susquehanna Nuclear LLC and Allegheny Electric Cooperative Inc. and is operated by Susquehanna Nuclear. Its two units generate approximately 2,500 megawatts of carbon-free electricity, enough to power approximately two million homes. For information, visit
