Swinging power lines cause outage

Penn Valley’s large power outage Monday apparently was caused when two 60,000-volt power lines swung together near Penn Valley, leaving more than 6,000 people without power.

The blackout began at 6:16 p.m. when loose lines touched, said Lisa Randle, a spokeswoman for Pacific Gas & Electric. The contact tripped a circuit breaker.

Crews responded immediately and power was restored at 8:08 p.m., Randle said.

Some slack is needed to allow lines to respond to temperature changes, Randle said. Crews continued inspecting lines in the area Tuesday.
