Utility rules and programs for San Antonio
City of San Antonio and Pedernales Electric Cooperative, serve Bexar County, so which rules apply depends on your address.
| Utility | Type | Battery and related programs |
|---|---|---|
| City of San Antonio | city-owned | Its SolarHostSA rooftop program is described in the past tense on its page; ask whether any program is open. |
| Pedernales Electric Coop, Inc | member-owned cooperative | Application and inspection fees are listed inconsistently across PEC pages ($150 to $500); check its fee page. |
Program details are from each utility’s own pages (read October 2026). See the Texas incentives table for statewide credits and a status for every program.
What to plan for in San Antonio
- Hail (very high): Hail is hard on rooftop solar; ask installers about impact-rated panels and your insurer about coverage.
- Tornadoes (very high): Tornado-season storms cut power quickly. A battery that switches on by itself, or a portable generator ready to go, covers the first night; sirens and weather radios need power too.
- 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.
Permits and approvals in San Antonio
- San Antonio Development Services Department (DSD): permit information · 210-207-1111

- The utility must approve the connection before you switch on: CPS Energy · Pedernales Electric Cooperative · your own utility’s interconnection page.
