EV Charging in Oklahoma: What the Numbers Mean
Oklahoma's residential electricity rate is 11.4¢/kWh — 4.7¢ 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 $391/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 $761/year — $3,805 over 5 years, before incentives.
Home Charging vs Public Charging in Oklahoma
The biggest driver of EV cost is where you charge. Home charging at 11.4¢/kWh is always the cheapest option. Public Level 2 stations average around 28.5¢/kWh — 2.5x more expensive. DC fast chargers run about 33.9¢/kWh. Tesla Superchargers in Oklahoma are estimated at 25.1¢–31.2¢/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 $1162/year in Oklahoma, narrowing the gap with gas considerably.
