Utility rules and programs for San Bernardino
Southern California Edison serves homes in San Bernardino.
| Utility | Type | Generator rules |
|---|---|---|
| Southern California Edison Co | investor-owned | A transfer switch or battery backup needs a licensed electrician (C-10), a city or county electrical permit and, for solar or batteries, your utility’s approval; PG&E lists a free Backup Power Transfer Meter program for some customers. |
Program details are from each utility’s own pages (read October 2026). See the California incentives table for statewide credits and a status for every program.
What to plan for in San Bernardino
- Landslides (very high): Decide what must stay on and size backup to that.
- Wildfires (very high): Wildfire risk can mean planned shutoffs and smoke. A battery charged by solar gives quiet backup, and fueled generators need extra care on dry days and clear space around them.
- River and heavy-rain flooding (very high): Heavy rain can flood basements and take out power. Put sump pumps on backup power and keep equipment above the flood line.
