Utility rules and programs for Peoria
APS, SRP, City of Mesa and USBIA-San Carlos Project serve Maricopa County, so which rules apply depends on your address.

| Salt River Project | public power | Ask the utility which transfer-switch and interconnection rules apply. APS and SRP require a transfer switch that can never feed the grid. |
| City of Mesa | city-owned | Ask the utility for its transfer-switch and interconnection rules; we have not verified them. |

Program details are from each utility’s own pages (read October 2026). See the Arizona incentives table for statewide credits and a status for every program.
What to plan for in Peoria
- Heat waves (very high): Heat waves strain the grid just when air conditioning matters most. Decide what must stay cool, such as one room, medicine and the fridge, and size backup to that rather than the whole house.
- 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.
- Hail (very high): Hail is hard on rooftop solar; ask installers about impact-rated panels and your insurer about coverage.
