Southern California Edison, a utility subsidiary of Rosemead-based Edison International, announced on Nov. 8 that a problem with its transmission grid occurred near the point of origin of the massive Woolsey Fire in Los Angeles and Ventura counties. According to press reports, SoCal Edison reported to the California Public Utilities Commission that on Nov. 8 – the day the Woolsey Fire started – a circuit in its power transmission grid at its Chatsworth substation recorded a “disturbance” two minutes before the first report of fire came in from the Chatsworth area. On Nov. 12, the San Jose Mercury News reported that the PUC has launched probes into both SCE and Pacific Gas and Electric – a unit of San Francisco-based PG&E Corp. – to assess whether the utilities complied with existing rules and regulations for their equipment in the current fire zones.
