The short answer: A 2026 Tesla Model Y Long Range AWD costs about $4.54 per 100 miles to charge at home in New Mexico, and $14.85 for the energy to drive its 327-mile EPA range. That uses the August 2026 residential average of 16.51¢/kWh, up from 15.98¢/kWh in August 2025 and about 9% below the U.S. residential average of 18.16¢/kWh. The same 100 miles cost about $13.85 in a 30-mpg gas SUV at AAA’s New Mexico average of $4.154 a gallon (October 28, 2026), and about $14.85 at a public DC fast charger.
EV vs gas in New Mexico: cost per 100 miles
New Mexico’s regular gas averaged $4.154 a gallon on October 28, 2026, the 22nd-cheapest among the 50 states and the District (AAA). Electricity in New Mexico is the 25th-highest residential average among the 50 states and the District of Columbia.

| 2026 Tesla Model Y Long Range AWD, charged at home | 16.51¢/kWh × 27.50 kWh | $4.54 | $545 | 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 |

- Home charging vs the gas SUV: about $1,117 a year less at 12,000 miles. Home charging stays cheaper until electricity reaches about 50.35¢/kWh, 3.0× the state average.
- Home charging vs the hybrid: home charging is about $614 a year cheaper. The break-even against the hybrid is 35.13¢/kWh.
- Public fast charging vs gas: relying on DC fast charging costs more than the gas SUV at these prices ($14.85 vs $13.85 per 100 miles). The savings come from charging at home.
Checked on the Model Y: 27.50 kWh/100 mi × $0.1651/kWh = 4.5403, which rounds to $4.54 per 100 miles. The gas SUV is 100 ÷ 30 mpg × $4.154 = 13.8453, or $13.85. The break-even electricity price is $13.85 ÷ 27.50 kWh = 50.35¢ per kWh.
Utility EV rates in New Mexico
The Alternative Fuels Data Center lists 3 utilities in New Mexico with a residential EV time-of-use rate or managed-charging program: El Paso Electric, El Paso Electric Co and Xcel Energy. AFDC records the program type, not the price, so check the tariff before you assume an off-peak rate.

- Xcel Energy: EV time-of-use rate. AFDC record · utility EV page
Why it matters: the state average above blends every rate plan. An overnight EV rate is usually the cheapest power a utility sells, and the car can be scheduled to charge only in that window. Put the off-peak price from your tariff into the calculator to see the difference.
Public charging in New Mexico
The AFDC counted 1,274 public charging ports at 494 locations in New Mexico on October 28, 2026: 653 Level 2 and 619 DC fast, plus 2 Level 1. AFDC also counts about 16,600 battery-electric vehicles registered in New Mexico through 2025 (0.8% of light-duty registrations). That is about 13.0 EVs per public port, against 21.7 nationally, the 16th-fewest EVs per port among the 50 states and the District. The two counts are from different dates, so treat the ratio as a rough measure of how busy public charging is.
Paren’s Q3 2026 report does not state a New Mexico fast-charging average, so this page uses its U.S. average of $0.540 per kWh (off-peak $0.438, peak $0.637). Tesla Supercharger members averaged $0.396 and non-members $0.569 nationally.
Fast chargers usually bill the energy delivered to the car, which is less than the EPA wall figure. A rough estimate of delivered energy, the wall figure × 0.894 (mean Level 2 AC efficiency from Sears, Roberts, and Glitman, 2014, not a DC fast measurement), puts the Model Y at about $13.28 per 100 miles at $0.540/kWh. Per-minute billing and idle fees are not modeled.

How much does it cost to charge an EV at home in New Mexico?
At the EIA August 2026 average residential price of 16.51¢ per kWh, a 2026 Tesla Model Y Long Range AWD costs about $4.54 per 100 miles and $14.85 for the wall energy to drive its 327-mile EPA range. Across the five EVs on this page the home cost is $4.01 to $5.19 per 100 miles. EPA consumption is measured at the wall, so charging losses are already included.
Is charging an EV cheaper than buying gas in New Mexico?
At home, yes, against a gas SUV. With AAA’s New Mexico average of $4.154 a gallon for regular on October 28, 2026, a 2026 Honda CR-V FWD (30 mpg EPA combined) costs about $13.85 per 100 miles, versus $4.54 for the Model Y charged at the August 2026 residential average. A 2026 Toyota RAV4 hybrid (43 mpg) costs about $9.66, so home charging is also cheaper than that hybrid in New Mexico. Home charging stays cheaper than the gas SUV until electricity reaches about 50.35¢ per kWh.
Is public DC fast charging more expensive than gas in New Mexico?
For the Model Y at Paren’s Q3 2026 U.S. average of $0.540 per kWh, 100 miles of EPA wall energy costs about $14.85. That is more than the $13.85 the gas SUV spends on the same miles at the AAA average, and $10.31 more than charging at home. Prices at a given station vary, and some stations bill by the minute.
Do New Mexico utilities offer EV charging rates?
The Alternative Fuels Data Center lists 3 utilities in New Mexico with a residential EV time-of-use rate or managed-charging program: El Paso Electric, El Paso Electric Co and Xcel Energy. AFDC records the program type, not the price, so check the tariff before you assume an off-peak rate.
How many public EV chargers are there in New Mexico?

Is 16.51¢ per kWh the rate on my New Mexico electric bill?
No. It is the statewide average residential retail price for August 2026 from EIA Table 5.6.A, and EIA marks 2026 values as preliminary. A time-of-use period, rider, tax, or fixed fee can move your all-in price. Open the VoltEdge charging-cost calculator and replace the prefilled average with the energy rate on your bill.
