GUC says fault on transmission line sparked major power outage on Saturday

GREENVILLE, N.C. (WITN) – Greenville Utilities believes a fault on a transmission line sparked a huge power outage on Saturday that turned the lights out for a third of the city.

GUC says the fault caused a circuit breaker on a transformer at the main point of delivery substation on Mumford Road to trip and shut off.

Power was out for about 90 minutes, with residential customers fully restored by 12:15 p.m.

Because of a construction project underway on the Duke Energy side of the substation, another GUC transformer there was offline. The utility says had that project not been ongoing, that second transformer should have been able to keep the power grid online.

GUC says they found no damage to the substation equipment or the circuit that went down. It plans to energize the circuit later this week.
