Powder River Energy Corporation (PRECorp) announced the caused of Sunday’s power outage that left hundreds without heat for as long as six hours.

PRECorp said it was due to a transformer at the Gap Substation where a sensor tripped before the equipment overheated. Officials said crews knew fairly quickly what the problem was, however rerouting power at the Substation level was complex.

The company deployed a step restoration strategy to get everyone back before the temperatures dropped.

The power outage was reported just before 11:30 a.m., which affected nearly 2,700 meters. The power to most was restored in three hours.

The last 70 customers, between Antelope Valley-Crestview and Wright had power about two hours after that when the company announced service to all meters had been restored by 6 p.m.
