A significant power outage struck Southern California on Thursday evening, affecting over 100,000 customers across multiple counties. The disruption began at 7:41 p.m. and lasted for approximately one hour and fifteen minutes. San Diego Gas & Electric (SDG&E) reported the incident impacted areas from Carlsbad to Escondido and into Orange County. The utility company has restored power but has not yet determined the cause of the failure. This event highlights vulnerabilities in regional energy infrastructure.
The outage created a broad swath of darkness across North San Diego County. Affected coastal communities included Carlsbad, Encinitas, and Cardiff-by-the-Sea. Inland areas like Rancho Bernardo, Escondido, and San Pasqual also lost power. The disruption even extended north into southern Orange County. Residents in Mission Viejo and San Juan Capistrano experienced the blackout.
At its peak, the outage impacted more than 100,000 customer accounts. Power was fully restored by approximately 8:56 p.m. on Thursday. SDG&E’s Media Relations Manager, Anthony Wagner, acknowledged the disruption in a statement. He emphasized the company’s commitment to investigating the root cause. The safety of customers and employees remains their top priority.
For international context, California’s grid faces unique climate and demand pressures. The state has experienced rolling blackouts during extreme heat waves in recent years. This incident, while brief, adds to concerns about grid reliability. Aging infrastructure and increased wildfire risks compound these challenges. Utilities are investing billions in grid modernization and hardening efforts.
The cause of Thursday’s outage remains under investigation by SDG&E engineers. Such widespread failures can stem from equipment malfunctions or transmission line issues. Southern California’s interconnected grid means local problems can have regional effects. The rapid restoration suggests crews quickly isolated the fault. Further updates are expected as the investigation progresses.
