The Point Lepreau Nuclear Generating Station (PLNGS) has been temporarily taken offline, a proactive move aimed at ensuring long-term reliability for New Brunswick’s energy grid as we approach the colder months.

Why is the Station Offline?

According to a recent update from NB Power, the temporary shutdown is necessary to safely repair a gasket on the turbine system. This component is located on the conventional side of the station. The need for this repair was identified while the station was being powered back up following a planned maintenance outage.

During the power-up phase, teams conduct careful checks, adjustments, and monitoring to ensure all equipment performs as expected. It was during these routine checks that the gasket issue was spotted, prompting the temporary halt to ensure safety and energy security for New Brunswickers.

Focusing on Winter Reliability

While an unexpected pause in the return-to-service process might seem like a setback, NB Power officials emphasize that addressing the issue now is the most prudent course of action for the region’s power grid.

“This is the best path forward,” stated Steve Bagshaw, Site Vice President and Chief Nuclear Officer. “Taking the time now to complete this repair helps reduce the risk of unplanned interruptions during the winter months, helping ensure we are ready when customers need us most. This approach supports the long-term reliability of the Station.”

Safety First

NB Power has assured Saint John residents and all New Brunswickers that there is absolutely no risk to the staff, the public, or the environment due to this repair. The station is strictly following its established safety processes. It will only be returned to service once the gasket repair is finished and all necessary safety, technical, and operational reviews have been thoroughly completed.
