How much does it cost to charge a Kia EV9 in Texas?

Texas' 12-month average rate, 16.0¢/kWh, is 11% below the U.S. average of 18.0¢/kWh, which saves $0.78 per 100 miles compared with the national rate.

Rates in Texas are rising: the latest 12-month average is 4.8% higher than in the 12 months before.

Over the last 24 months Texas was cheapest in winter and most expensive in spring: January 2025 at 14.6¢/kWh and April 2026 at 17.0¢/kWh, which moves the Kia EV9's monthly charging cost between $56 and $66. The latest published month, August 2026, came in at 15.9¢/kWh, in line with the 12-month average.

Of the 5 states covered so far, Texas ranks 3rd cheapest for the Kia EV9. It costs least in Washington ($5.39 per 100 miles) and most in California ($12.29).

Among the 10 EVs on OutletBill, the Kia EV9 is the 9th cheapest to charge per mile in Texas. The cheapest is the Tesla Model 3 at $3.88 per 100 miles; the most expensive is the Rivian R1S at $6.85.

At 38.0 kWh per 100 miles, the 2026 Kia EV9 Standard Range RWD uses more energy than most 2026 EVs: 55% of the 321 versions EPA has tested are more efficient.

EPA rates the 2026 EV9 Standard Range RWD at the same efficiency as the 2025 version, 38.0 kWh per 100 miles, with the same 230-mile range.

Across all 5 trims of the 2026 EV9, cost per 100 miles in Texas ranges from $6.07 for the Long Range RWD to $6.87 for the GT, a difference of $97 a year at 1,016 miles a month.

EPA estimates 8 hours to charge the EV9 Standard Range RWD from empty on a 240-volt Level 2 home charger, short enough to finish overnight. At 1,016 miles a month (about 33 miles a day), a day's driving takes roughly 1 hour on a Level 2 charger.

Electricity would have to cost more than 37.5¢/kWh, 2.3 times Texas' rate, before the Kia EV9 cost more per mile than the 2027 Kia Telluride FWD. Put the other way, gas would have to fall below $1.34 a gallon.

Gas costs use EIA's Texas retail average for regular gasoline ($3.14 a gallon over the same 12 months, 13% below the U.S. average of $3.61) and the 2027 Kia Telluride FWD's EPA rating of 22 mpg combined.
