Counts checked October 10, 2026. A registration count says where chargers are going in, not whether your panel can carry one; that takes a load calculation.

Texas Charger Installation: What You Need to Know
Texas has unique considerations for EV charger installation:
- Permits are local: Texas licenses electricians statewide through TDLR, but the electrical permit comes from your city. Dallas, Houston, Austin, and San Antonio all require one. Outside city limits, check with the county before work starts.
- ERCOT grid considerations: Texas runs its own power grid. Time-of-use rates and demand response programs vary by utility. Charging overnight (off-peak) can save 40 to 60% on electricity costs.
- Heat matters: Texas garages can hit 120°F+. Hardwired installations are preferred over plug-in for reliability in extreme heat. Wire gauge may need upsizing for long outdoor runs in direct sun.
- New construction is panel-ready: most homes built after 2010 in DFW and Houston suburbs have 200A panels with available breaker space. These are the easiest installs: Tier 1, $500 to $1,500.

The Panel Upgrade Question in Texas
If you live in a DFW or Houston suburb built after 2000, you almost certainly have a 200A panel. That’s good news: most 200A panels can handle a 40A or 48A EV charger without an upgrade.
The homes that might need attention are:
- Older homes in inner-city Dallas, Houston, or San Antonio with 100A panels
- Homes with electric heat AND electric water heater AND electric range on a 100A panel
- Properties with Federal Pacific or Zinsco panels (safety issue regardless of EV)
Don’t guess. Don’t let a contractor guess for you. A $49.99 NEC Article 220 assessment gives you the definitive answer in minutes.

"I built ChargeRight because I was tired of seeing homeowners pay $2,000 to $4,500 for panel upgrades that a $49.99 load calculation would have shown they didn't need. The math doesn't lie. Every homeowner deserves to see it before they write a check."
