EV Charging in Texas: What the Numbers Mean
Texas's residential electricity rate is 14.1¢/kWh — 2.0¢ below the national average of 16.1¢/kWh, which works in EV owners' favor. At that rate, a typical EV (3.5 mi/kWh) costs $483/year to charge at home for 12,000 miles.
Compared to a 30 MPG gas car at $2.88/gal ($1152/year for the same miles), EV home charging saves $669/year — $3,345 over 5 years, before incentives.
Home Charging vs Public Charging in Texas
The biggest driver of EV cost is where you charge. Home charging at 14.1¢/kWh is always the cheapest option. Public Level 2 stations average around 35.3¢/kWh — 2.5x more expensive. DC fast chargers run about 34.7¢/kWh. Tesla Superchargers in Texas are estimated at 30.1¢–37.4¢/kWh depending on membership.
Most EV owners do 80%+ of their charging at home overnight. If you don't have home charging access, the economics shift significantly — charging entirely at public DC fast chargers would cost $1190/year in Texas, narrowing the gap with gas considerably.
