We're working to learn more about what caused a small explosion at a PG&E substation in Orovillle.
CAL FIRE crews were called to the scene of an explosion at the Cottonwood substation between Highway 99 and Highway 70, just off Cottonwood Road, at around 8:30 p.m. Monday. They say PG&E officials handled the situation before they arrived.
CAL FIRE says a condensor malfunctioned, and PG&E is working to repair the equipment. Power was only lost to one home in the area.
We're working to learn from PG&E the exact cause of the explosion. This is a developing story, we'll update you as we learn more.
