Substation transformer fire cuts power to about 15,000 people near Brea mall

A transformer fire at a substation near Imperial Highway and Associated Road in Brea, California, caused a power outage affecting approximately 15,000 people across Placentia, Fullerton and Brea, including the Brea Mall and the Brea Civic Center. Brea Fire Department responded to the fire, which was reported at around 5.15pm. Shoppers inside the darkened mall used phone flashlights and were reported to have been escorted out calmly. Power was restored to most areas by around 6.30pm. Traffic signals in the affected area lost power, and motorists were advised to treat intersections as four way stops while signal maintenance continued. A spokesperson for Southern California Edison said crews were still working to determine what triggered the fire, which the utility said occurred at one substation.

Not reported. Southern California Edison stated crews were still working to determine what triggered the fire at the time of reporting.

1. A single substation transformer failure can cause a wide area outage affecting commercial centres, civic buildings and traffic signals, so restoration planning should consider these dependencies.
2. Clear evacuation procedures and calm staff communication during sudden loss of lighting help prevent panic in public venues.
3. Rapid public communication, including social media updates on restoration and advice on unpowered traffic signals, reduces confusion and road risk during outages.
