On April 4 at 8:12 p.m., Catawba Nuclear Station lost offsite power and an unusual event was declared. Power has been restored to the station and the unusual event emergency classification was terminated at 1:37 a.m.
The station’s diesel generators operated as designed to provide power to essential plant equipment. An unusual event is the lowest of four emergency classifications. This condition posed no threat to public safety, but required certain emergency response functions to be in a heightened state of readiness.
Duke Energy’s emergency operations facilities were activated and station employees responded to the situation. Appropriate federal, state and local officials were also notified.
Although power has been restored to the station, the units are not currently generating electricity. An investigation is being conducted regarding the cause.
