When Do You Need a Panel Upgrade?
Many San Antonio homes still have 100-amp or even 60-amp electrical panels that cannot safely handle modern electrical loads. If breakers keep tripping, lights flicker, the breaker box feels hot, or the panel is outdated, CSW can inspect the electrical panel and explain whether repair, breaker replacement, or a full panel upgrade is the right next step. Adding a generator, EV charger, or major appliance almost always requires a panel upgrade.

Definition & Scope
What is this?
Upgrading or replacing an electrical panel to safely handle modern electrical loads or meet current building codes.
Scope of Work
Assessment of current electrical load, safe removal of old panel, installation of new breaker box, connection of new circuits, and CPS Energy meter coordination.
Cost Factors
- Amperage upgrade (e.g., 100A to 200A vs. 200A to 400A)
- Need for a new meter base or weatherhead
- Accessibility of the existing panel and wiring
Timeline Factors
- Schedule depends on service size, equipment condition, inspection timing, and utility coordination
- Subject to CPS Energy disconnection and reconnection schedules
Permit Considerations
- Panel upgrades may require City of San Antonio permits, inspection, and CPS Energy coordination based on scope.
Electrical Panel Upgrade Cost in San Antonio
| Service | Typical Range |
|---|---|
| 100A to 200A Panel Upgrade | $1,800 – $5,500 |
| 200A to 400A Panel Upgrade | $4,500 – $12,000 |
| Federal Pacific / Zinsco Replacement | $1,500 – $4,000 |
| Subpanel Installation | $500 – $1,500 |
| Single Breaker Replacement | $100 – $200 |
| Whole-Home Rewiring | $4,000 – $15,000+ |
A 200A to 400A upgrade is always more expensive than a 100A to 200A upgrade. The 400A service requires heavier service entrance wire, a new meter base, and CPS Energy coordination — significantly more work than a standard upgrade. Most SA homes only need 200A; 400A is for homes over 3,000 sqft or with multiple EV chargers, pools, or workshop equipment. Free on-site estimates provided.

City Inspection
We schedule and pass the city electrical inspection, then provide you with the signed permit for your records.
Common Reasons for Panel Upgrades
Panel upgrades are frequently required for generator installations, EV charger installations, and HVAC system replacements. They are also a common component of home remodels and damage restoration projects. If your home has a Federal Pacific or Zinsco panel, replacement is strongly recommended due to known safety issues. C.S.W. Power Solutions handles the entire process — from evaluation and permitting to installation and city inspection. For a full cost breakdown, visit our electrical panel upgrade service page or read our blog for detailed pricing guides.
