KELSEYVILLE – Thousands of residents of the Kelseyville and Cobb areas were out of power Sunday afternoon and into the evening due to equipment failure.

Brandi Ehlers of Pacific Gas & Electric Co. said a momentary power interruption just after 4 p.m. affected 8,500 customers.

A sustained outage for several more hours affected about 4,000 customers, said Ehlers.

The reason for the outages was equipment failure, but Ehlers said she was unsure of the origin of the equipment problems.

Power was restored to all of the area's customers by 7:30 p.m., Ehlers said.
