TUCSON, Ariz. (AP) -- Some 35,000 customers across a wide swath of Tucson, Ariz., and other parts of Pima County have lost power because of an equipment failure.
Tucson Electric Power spokesman Joe Salkowski says the scattered outages began about late Wednesday morning and affected homes, businesses and even traffic signals.
He says crews have restored power to about 3,000 customers, including the University of Arizona. They hope to have most power returned within several hours.
Salkowski says equipment failure at a substation near downtown limited use of a large transformer. Crews are trying to shift power onto adjacent circuits.
