Point Lepreau Nuclear Generating Station returns to operation

2025-12-15

Fredericton, NB — The Point Lepreau Nuclear Generating Station (PLNGS) returned to operation on December 14, 2025, following the safe completion of its planned maintenance outage. These outage activities are designed to enhance reliability, ensure long-term performance, and maintain the highest standards of nuclear safety.

The most complex work component of this year’s planned maintenance outage was the generator rewind, which involved replacing the stator windings inside the main generator on the conventional (non-nuclear) side of the station.

The team at PLNGS completed more than 23,000 tasks, including the replacement of motors, valves, and pumps; upgrades to electrical systems; and comprehensive testing and inspections. During an early synchronization to the electrical grid, the station experienced a challenge related to a turbine bearing, which postponed PLNGS’s return to service by two weeks. The bearing was successfully replaced, and the station returned to operation on Sunday following extensive verification and testing, which is part of the Station process and procedures.

As with all NB Power generation facilities, planned outages are an essential part of PLNGS’s maintenance strategy and standard in the industry. They provide the opportunity to inspect and service equipment that cannot be accessed while the Station is online and are critical to achieving long-term sustained performance at PLNGS.

“Bringing PLNGS safely back online demonstrates our team’s strong dedication to serving New Brunswickers. I’m proud of the workforce’s professionalism and expertise throughout this important maintenance outage to complete the work safely and with a strong focus on quality. Thanks to our employees, and our vendor and contractor partners for their expertise in the execution of this outage. A well-maintained plant operates more efficiently, extends the life of major equipment, and continues to deliver cost effective, clean, reliable power for our customers for years to come,” said Lori Clark, President and CEO.

The return of PLNGS strengthens the province’s energy system, ensuring dependable power for New Brunswickers throughout the high-demand winter season.

Costs associated with the outage will be included in NB Power’s annual financial statements, which are publicly available.
