Brittany McKannay of PG&E said the outage was caused by a broken switch at the Las Gallinas substation. The switch had opened and crews were unable to close it for a while, she said.
Joseph Robinow said on the San Rafael Patch Facebook page he was driving south on Highway 101 after 6 p.m. on Feb. 19, approaching Marinwood, when he saw “a very large flash of light ... up the hill on my left (just east of 101).”
A separate incident in Kentfield caused outages in the Gerstle Park neighborhood of downtown San Rafael. At about 6:30 p.m. Tuesday, a car struck a power pole at 15 Rosebank Avenue, not far from the junction of Wolfe Grade and Sir Francis Drake Boulevard, McKannay said.
About 3,600 customers lost electricity from that crash. Outages were reported in Kentfield, Greenbrae, the Wolfe Grade area and Gerstle Park. The College of Marin posted on its Facebook page at 8 p.m. that all night classes were cancelled due to the outage.
McKannay said it would be late Wednesday morning by the time repair crews finished installing a new power pole and hanging the power lines. She credited firefighters for clearing the area and maintaining safety before the PG&E repair crew arrived.
