Oklahoma EV vs gas · Gas October 12, 2026 · Electricity rates 2025
Yes, by a lot. On OG&E's average home rate, charging an EV costs the same per mile as gas at $1.01 a gallon. Gas in the Oklahoma City metro averaged $4.00 on October 12, 2026, so 1,000 miles a month costs about $37 to charge versus $148 in gas: roughly $111 a month back.
What you pay for power sets what charging costs. Here are the numbers for Oklahoma City.
Serves Oklahoma City and much of central Oklahoma
Average home rate 12.5 cents per kWh (2025). Charging costs the same per mile as gas at $1.01 a gallon: about $37 for 1,000 miles versus $148 in gas.
Some suburbs, like Edmond, have their own city utility, and rural areas may be served by a co-op.
Gas prices jumped in 2026 when the war with Iran disrupted oil shipping through the Strait of Hormuz. Home electricity is priced by utilities under state regulators and moves far more slowly, so the gap tends to widen when gas spikes. For a 27 mpg car to cost less per mile than charging at home in Oklahoma City, gas would have to fall below $1.01 a gallon.
Why an EV opts you out of gas spikes · Is an EV cheaper than gas right now? Every state

Oklahoma EV incentives · EV fees by state
We assume 1,000 miles a month, a typical new EV that uses 30 kWh per 100 miles, a 27 mpg gas car, and home charging at each utility's average residential rate, which includes its fixed monthly charges. An overnight or EV rate is often cheaper than that average, and public fast charging costs much more. Treat this as the honest average, not your bill.

At home, about $37 per 1,000 miles on OG&E (12.5 cents per kWh), for a typical EV that uses 30 kWh per 100 miles. Public fast charging costs much more per kWh than home charging, so these numbers assume you charge at home most of the time.
