Operators at Oyster Creek Generating Station safely returned the station to service December 4 at 11:55 a.m. ET, while plant personnel make repairs to one of the station's two main transformers.
Oyster Creek operators took the station's turbine offline December 3 at 1:04 a.m. after observing abnormal indications in one of the plant's new transformers. At that time, the station was in start up mode following a 30-day refueling outage.
Oyster Creek uses two transformers to convert the plant's electrical output for use on the region's grid. The station will operate at reduced power on one transformer while repairs are made to the second transformer.
There was no impact on aquatic life in the canal, and Exelon's environmental experts are monitoring the canal for any potential impact due to reduction in power.
Oyster Creek is located approximately 60 miles east of Philadelphia. The plant produces 636 net megawatts of electricity per hour, enough carbon free energy for approximately 600,000 homes, the equivalent of all of the homes in Mercer, Burlington and Ocean counties.
