Crews are working this morning to restore power to about 3,360 Pacific Power customers in the Upper Rogue area.

All power should be back on by 11:15 a.m., said Monte Mendenhall, spokesman for Pacific Power.

The start of the day at some schools was delayed because of the outage.

An outage related to a failed transmission line disrupted electricity service to 7,251 customers in the Shady Cove, Prospect and Sams Valley areas at 5:07 a.m., said Mendenhall.

At 7:30, the company switched to other sources, restoring electricity to more than half the customers, Mendenhall said.

He said the outage occurred when a transmission line fell but that it is not yet clear why that happened.
