Entergy's Louisiana unit tripped from 75% power during turbine electrohydraulic testing ahead of a refueling outage, the 2B bus fast transfer failed, and Emergency Diesel Generator B started and loaded. Transfer schemes and turbine trip testing are where backup power quietly fails, and the same lesson applies to every gas plant and data center that relies on automatic transfer.
