TUCSON, Ariz. (KVOA) — Over 18,000 Tucson Electric Power customers experienced a power outage in Oro Valley and Tucson due to an electrical fault on Wednesday afternoon.

According to TEP, a total of 18,495 customers across the Tucson area, Catalina and Oro Valley were without power on Nov. 12. 

TEP said the power outage was due to an electrical fault that affected a substation which provides 46-kilovolt service to multiple areas in the city. The power outages started at 2:08 p.m. and lasted nearly an hour and 10 minutes. Multiple breakers are opened and are operating normally. 

TEP inspected the system but a cause wasn’t identified initially. 

“After determining it was safe to re-energize our equipment, we were able to bring most customers back into service,” TEP said.

As of 4:30 p.m., 300 customers remain out of service.

More information on the power outages can be found on the TEP website.
