About 2500 PG&E customers in San Luis Obispo County’s North Coast could be without power Friday night. Officials say a planned outage is part of a large, scheduled repair job on a 70,000-volt transmission line that feeds the distribution system for Cambria and Cayucos. Residents can expect the outage to take place between 10 and 10:30 Friday night. Officials say it should only last between five and 15 minutes.
