Utility rules and programs for Fresno
Pacific Gas & Electric serves homes in Fresno.
| Utility | Type | Generator rules |
|---|---|---|
| Pacific Gas & Electric 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 Fresno
- Drought (very high): Drought raises fire and heat risk and strains wells. If you rely on a well pump, include it in your backup plan.
- Earthquakes (relatively high): Earthquake risk is mainly about secure mounting and gas shut-off for generators; ask the installer to follow local seismic requirements.
- River and heavy-rain flooding (relatively high): Heavy rain can flood basements and take out power. Put sump pumps on backup power and keep equipment above the flood line.
