A whole house standby generator in Orange County typically costs about $10,000 to $20,000+ installed, including the transfer switch, gas line and permits. A portable generator inlet with a manual transfer switch costs about $800 to $2,500. Call 657-201-1586 to get connected with a licensed electrician who installs generators, transfer switches and battery backup.
Backup power options
- Whole house standby generator: natural gas or propane, starts automatically through an automatic transfer switch.
- Portable generator inlet and interlock or manual transfer switch: the safe way to power selected circuits from a portable generator. Never back-feed through an outlet.
- Battery backup: wall batteries paired with solar or used alone, often on a critical-loads sub panel.
Power shutoffs in Orange County
During high fire-risk winds, Southern California Edison and SDG&E may switch off power to canyon and foothill neighborhoods through Public Safety Power Shutoffs. Homes near the Santa Ana Mountains, Yorba Linda, Anaheim Hills, Orange Park Acres and south county canyons are most often affected. Backup power keeps refrigerators, medical devices, garage doors and internet running.
Permits and placement
Generators need electrical and often mechanical permits, plus HOA approval in many communities. Placement must meet clearances from windows, doors and property lines, and city noise limits.
