The short answer: A 2026 Tesla Model Y Long Range AWD costs about $4.33 per 100 miles to charge at home in South Carolina, and $14.17 for the energy to drive its 327-mile EPA range. That uses the August 2026 residential average of 15.76¢/kWh, up from 15.16¢/kWh in August 2025 and about 13% below the U.S. residential average of 18.16¢/kWh. The same 100 miles cost about $12.46 in a 30-mpg gas SUV at AAA’s South Carolina average of $3.737 a gallon (October 28, 2026), and about $14.85 at a public DC fast charger.

|---|---|---|---|---|
| 2026 Tesla Model Y Long Range AWD, charged at home | 15.76¢/kWh × 27.50 kWh | $4.33 | $520 | 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) | $3.737/gal ÷ 43 mpg | $8.69 | $1,043 | EPA · AAA |

- Home charging vs the gas SUV: about $975 a year less at 12,000 miles. Home charging stays cheaper until electricity reaches about 45.30¢/kWh, 2.9× the state average.
- Home charging vs the hybrid: home charging is about $523 a year cheaper. The break-even against the hybrid is 31.60¢/kWh.
- Public fast charging vs gas: relying on DC fast charging costs more than the gas SUV at these prices ($14.85 vs $12.46 per 100 miles).
Checked on the Model Y: 27.50 kWh/100 mi × $0.1576/kWh = 4.3340, which rounds to $4.33 per 100 miles. The gas SUV is 100 ÷ 30 mpg × $3.737 = 12.4573, or $12.46. The break-even electricity price is $12.46 ÷ 27.50 kWh = 45.30¢ per kWh.

Public charging in South Carolina
The AFDC counted 2,257 public charging ports at 713 locations in South Carolina on October 28, 2026: 1,287 Level 2 and 967 DC fast, plus 3 Level 1. AFDC also counts about 35,700 battery-electric vehicles registered in South Carolina through 2025 (0.7% of light-duty registrations). That is about 15.8 EVs per public port, against 21.7 nationally, the 21st-fewest EVs per port among the 50 states and the District.
Paren’s Q3 2026 report has no South Carolina 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.
