The short answer: A 2026 Tesla Model Y Long Range AWD costs about $8.83 per 100 miles to charge at home in Maine, and $28.87 for the energy to drive its 327-mile EPA range. That uses the August 2026 residential average of 32.11¢/kWh, up from 28.14¢/kWh in August 2025 and about 77% above the U.S. residential average of 18.16¢/kWh. The same 100 miles cost about $14.29 in a 30-mpg gas SUV at AAA’s Maine average of $4.287 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 | 32.11¢/kWh × 27.50 kWh | $8.83 | $1,060 | 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) | $4.287/gal ÷ 43 mpg | $9.97 | $1,196 | EPA · AAA |

- Home charging vs the gas SUV: about $655 a year less at 12,000 miles. Home charging stays cheaper until electricity reaches about 51.96¢/kWh, 1.6× the state average.
- Home charging vs the hybrid: home charging is about $137 a year cheaper. The break-even against the hybrid is 36.25¢/kWh.
- Public fast charging vs gas: relying on DC fast charging costs more than the gas SUV at these prices ($14.85 vs $14.29 per 100 miles).
Checked on the Model Y: 27.50 kWh/100 mi × $0.3211/kWh = 8.8302, which rounds to $8.83 per 100 miles. The gas SUV is 100 ÷ 30 mpg × $4.287 = 14.2890, or $14.29. The break-even electricity price is $14.29 ÷ 27.50 kWh = 51.96¢ per kWh.

Public charging in Maine
The AFDC counted 1,632 public charging ports at 656 locations in Maine on October 28, 2026: 1,194 Level 2 and 435 DC fast, plus 3 Level 1. AFDC also counts about 11,900 battery-electric vehicles registered in Maine through 2025 (0.9% of light-duty registrations). That is about 7.3 EVs per public port, against 21.7 nationally, the 3rd-fewest EVs per port among the 50 states and the District.
Paren’s Q3 2026 report has no Maine 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.
