A jumper on the Chugach Electric power line to Seward failed at around 3 a.m. Tuesday morning, causing power outages throughout the city. Crews were notified, and power was restored at around 5 a.m. via city generators. Senior Power Plant Operator Asa Turner maintained the generators until Chugach crews managed to restore power.
“We’re currently under generation, running five out of six generators,” Turner reported during the day on Tuesday as the outage underwent diagnosis. “We are currently in contact with Chugach dispatch on restoration. They’ll let us know when repairs are made, we’ll do some switching, and we’ll start shedding the load.”
At 3:30 p.m., crews cut power to the Moose Pass circuit in order to work on the line to Seward. Chugach Electric Communications Manager Julie Hasquet explained that the Moose Pass outage was necessary because the circuits share a common power pole.
“One of the jumpers that connects the transmission line has failed, and they have to replace that,” Hasquet said. “They have to isolate and ground in order to do it safely.”
Chugach Electric repaired the faulty jumper and restored power to both circuits by 5:15 p.m., over three hours ahead of their estimated 8:30 p.m. projection. Seward then fully made the transition from its generators back to Chugach power by 6:15 p.m.
