Pilgrim Remains Offline Due to Repairs


PLYMOUTH – The Pilgrim Nuclear Power Station remains out of service after plant officials discovered they needed to replace a start-up transformer at the Plymouth facility.

The station was taken off the grid on March 6 due to a leak in a feedwater heating system. Pilgrim staff made to the decision to stay offline after the repairs were made in anticipation of power difficulties with the March 13 nor’easter.

The station has been plagued by a series of unplanned shutdowns during winter storms in recent years.

After Eversource restored power to the off-site lines on March 15, a series of tests were conducted and inspectors reported that the start-up transformer on the non-nuclear side of the plant would have to be replaced.

The equipment brings power from the 345kv transmission lines into the station.

According to a statement, the replacement process is now underway. It’s not yet known when the plant will return to service.

Pilgrim is scheduled to permanently close in 2019. The station is under the highest level of federal oversight due to a series of safety violations.
