The short answer: A 2026 Tesla Model Y Long Range AWD costs about $4.08 per 100 miles to charge at home in Oklahoma, and $13.33 for the energy to drive its 327-mile EPA range. That uses the August 2026 residential average of 14.82¢/kWh, up from 14.42¢/kWh in August 2025 and about 18% below the U.S. residential average of 18.16¢/kWh. The same 100 miles cost about $13.06 in a 30-mpg gas SUV at AAA’s Oklahoma average of $3.919 a gallon (October 28, 2026), and about $14.85 at a public DC fast charger.

| How you fuel | Math | Per 100 mi | 12,000 mi/yr | Source |
|---|---|---|---|---|
| 2026 Tesla Model Y Long Range AWD, charged at home | 14.82¢/kWh × 27.50 kWh | $4.08 | $490 | EPA · EIA |
| 2026 Tesla Model Y Long Range AWD, public DC fast | $0.540/kWh × 27.50 kWh | $14.85 | $1,782 | Paren, U.S. average |
| 2026 Toyota RAV4 (2.5 L hybrid, 2WD) | $3.919/gal ÷ 43 mpg | $9.11 | $1,094 | EPA · AAA |
| 2026 Honda CR-V FWD (1.5 L turbo, gas) | $3.919/gal ÷ 30 mpg | $13.06 | $1,568 | EPA · AAA |
- Home charging vs the gas SUV: about $1,078 a year less at 12,000 miles. Home charging stays cheaper until electricity reaches about 47.51¢/kWh, 3.2× the state average.
- Home charging vs the hybrid: home charging is about $604 a year cheaper. The break-even against the hybrid is 33.14¢/kWh.
- Public fast charging vs gas: relying on DC fast charging costs more than the gas SUV at these prices ($14.85 vs $13.06 per 100 miles).
Checked on the Model Y: 27.50 kWh/100 mi × $0.1482/kWh = 4.0755, which rounds to $4.08 per 100 miles. The gas SUV is 100 ÷ 30 mpg × $3.919 = 13.0643, or $13.06. The break-even electricity price is $13.06 ÷ 27.50 kWh = 47.51¢ per kWh.

EV rebates and tax credits in Oklahoma
We found no open state EV rebate or tax credit in Oklahoma, and no utility charger rebate we could verify, when we checked in November 2026.

Public charging in Oklahoma
The AFDC counted 1,666 public charging ports at 396 locations in Oklahoma on October 28, 2026: 644 Level 2 and 1,021 DC fast, plus 1 Level 1. AFDC also counts about 26,800 battery-electric vehicles registered in Oklahoma through 2025 (0.6% of light-duty registrations). That is about 16.1 EVs per public port, against 21.7 nationally, the 22nd-fewest EVs per port among the 50 states and the District.
Paren’s Q3 2026 report has no Oklahoma figure, so fast-charging math here uses its U.S. average of $0.540 per kWh.
Stations that bill energy delivered to the car charge less than the EPA wall figure. As a rough estimate (wall energy × 0.894, a Level 2 efficiency from Sears et al., 2014), the Model Y comes to about $13.28 per 100 miles at $0.540/kWh.
