UPDATE: Power restored to more than 1,800 customers in Elk Grove

6:27 p.m. update:

Power was restored in more than 1,800 households as of 6:27 p.m.

5:07 p.m. update:

SMUD personnel are making progress on the power outage in northwest Elk Grove. There were 273 customers without power at 5:07 p.m.

The power outage was caused by a failure of an underground cable, according to SMUD spokesman Christopher Capra.

SMUD originally listed the cause of the power outage as vehicle-damaged equipment. Capra told The Bee later in the evening that was an error.

Original Story:

Power was restored for more than 1,400 customers in the Valley Hi/North Laguna area of Elk Grove after a vehicle hit electrical equipment, leaving customers without power for nearly two hours, according to SMUD.

Four-hundred customers are still out of power, according to SMUD spokesman Christopher Capra. The power should be restored for all by 4:50 p.m. Thursday, he said.

The equipment was damaged in the area of Big Horn and Franklin boulevards at 2:14 p.m. SMUD estimates 1,810 ratepayers were impacted as of 2:50 p.m.

The initial estimate for restoration was 3:20 p.m., according to SMUD’s outage page.

Capra said technicians are investigating the source of the problem. If a cubicle-pad transporter – one of the green boxes found along streets that service underground cables – was impacted, most customers should regain power within two hours, he said.

However, if the vehicle damaged a pole, Capra estimated it could take six to eight hours.

Capra warned that some customers could get power before others.

“Sometimes in these situations, we can get some customers back on power by switching them to other circuits,” he said. “That’s probably in process right now.”
