The short answer: A 2026 Tesla Model Y Long Range AWD costs about $6.74 per 100 miles to charge at home in Connecticut, and $22.04 for the energy to drive its 327-mile EPA range. That uses the August 2026 residential average of 24.51¢/kWh, down from 30.17¢/kWh in August 2025 and about 35% above the U.S. residential average of 18.16¢/kWh. The same 100 miles cost about $14.27 in a 30-mpg gas SUV at AAA’s Connecticut average of $4.282 a gallon (October 28, 2026), and about $14.85 at a public DC fast charger.

| 2026 Tesla Model Y Long Range AWD, public DC fast | $0.540/kWh × 27.50 kWh | $14.85 | $1,782 | Paren, U.S. average |

- Home charging vs the gas SUV: about $904 a year less at 12,000 miles. Home charging stays cheaper until electricity reaches about 51.91¢/kWh, 2.1× the state average.
- Home charging vs the hybrid: home charging is about $386 a year cheaper. The break-even against the hybrid is 36.21¢/kWh.
- Public fast charging vs gas: relying on DC fast charging costs more than the gas SUV at these prices ($14.85 vs $14.27 per 100 miles).
Checked on the Model Y: 27.50 kWh/100 mi × $0.2451/kWh = 6.7403, which rounds to $6.74 per 100 miles. The gas SUV is 100 ÷ 30 mpg × $4.282 = 14.2747, or $14.27. The break-even electricity price is $14.27 ÷ 27.50 kWh = 51.91¢ per kWh.

Public charging in Connecticut
The AFDC counted 4,982 public charging ports at 1,668 locations in Connecticut on October 28, 2026: 4,212 Level 2 and 761 DC fast, plus 9 Level 1. AFDC also counts about 48,800 battery-electric vehicles registered in Connecticut through 2025 (1.6% of light-duty registrations). That is about 9.8 EVs per public port, against 21.7 nationally, the 8th-fewest EVs per port among the 50 states and the District.
Paren’s Q3 2026 report has no Connecticut 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.
