Charging the median electric car at home in New Mexico costs about $53 a month at 15.06 cents per kilowatt-hour — the 14th cheapest of 51 states, and 18 per cent below the national average. Petrol over the same 1,125 miles costs $170, so the saving is $117 a month, $1,403 a year; on the public side 27 registered cars share each fast-charging plug, against 55 in the typical state.
Public fast charging in New Mexico
New Mexico has 177 public DC fast-charging sites with 611 plugs in the federal AFDC station locator (2026-09-16), for 16,600 battery-electric cars registered in the state at the end of 2025.
By the measure that matters on a Friday afternoon — cars divided by plugs — New Mexico is among the best-served states in the country: 27 registered EVs for every public fast-charging plug where the typical state manages 55 — 8th of 51. That is not a charger on every corner; it means the ones that exist are less likely to have a queue.
38% of the sites in New Mexico have a single plug and the state averages 3.5 plugs per site — enough that a busy stop usually has another bay, not enough to count on it off the interstate.
No operator dominates New Mexico: the largest, Tesla, holds 36% of the plugs (218 of 611). That is a more competitive market than most states, and it also means more apps and accounts to keep.
Which plug fits in New Mexico
The plug question in New Mexico has a clear answer: 86% of the sites carry CCS1, the connector on almost every non-Tesla EV sold in the US, against 18% carrying the Tesla NACS plug. A CCS car has the run of the state; a Tesla is at home on its own network and needs an adapter elsewhere.
| Connector | Sites in New Mexico | Share of sites | Cars that use it |
|---|---|---|---|
| CCS1 (J1772 Combo) | 153 | 86% | Almost every non-Tesla EV sold in the US |
| NACS / J3400 (Tesla) | 31 | 18% | Teslas, and other cars with an adapter where the site allows it |
| CHAdeMO | 92 | 52% | Older Nissan Leaf and Mitsubishi only |
CHAdeMO is unusually well represented here: 52% of New Mexico’s sites still carry it (92 of 177). That is a legacy of early buildout rather than a live standard — no car sold new in the US takes it, and those bays are worth nothing to a car bought this decade.
Public fast charging does not follow the residential rate. At a typical network price of $0.48 per kWh the median car costs $14.93 per 100 miles — 3.2 times what the same miles cost at home in New Mexico, and still under the $15.07 the petrol car spends on them. Anyone charging mostly in public in New Mexico should read the home column as optimistic by a factor of 3.2 — that multiple, not the state, is what decides whether the sums work. How long each car takes on a fast charger is on its charging page.
What electricity costs in New Mexico
The EIA published residential average for New Mexico is 15.06 cents per kWh (June 2026), against a US average of 18.34. That puts New Mexico at 14th of 51 states and DC, cheapest first — the cheaper half of the country. Put the Chevrolet Equinox EV FWD on that rate — the middle car of the 36 rated here, at 31.1 kWh per 100 miles — and it costs $4.68 per 100 miles, $53 a month, $632 a year.
Against a 27 mpg car at $4.07 a gallon, electricity stops being the cheaper fuel at about 48 cents per kWh. New Mexico is below that line by 33.41 cents, so the saving holds at the state-average rate before any overnight tariff is applied. It is an average across every household and every hour of the month: an overnight window beats it, a summer peak does not. The running-cost calculator takes your own tariff instead of the state’s.
Every EPA-rated car, charged at home in New Mexico
Efficiency is worth more in New Mexico than in most states: $71 a month separates the Lucid Air Pure RWD from the GMC Hummer EV Pickup 3X, and every car in the table still beats the $170 the petrol car burns through.

EPA combined ratings are measured at the socket, not at the battery, which is why these numbers are about a tenth higher than a pack-size calculation would give. That is the honest figure: it is what the meter in New Mexico records. The four cars without a US rating are in kilometres on the national page.
New Mexico against its neighbours
Utah, Oklahoma are cheaper than New Mexico; Arizona, Colorado, Texas are dearer. Same car in every row, so the columns are comparable: New Mexico is cheaper than 3 of the 5 states it touches.
| State | Cents / kWh | Rank | Chevrolet Equinox EV FWD / month | Fast plugs | EVs per plug |
|---|---|---|---|---|---|
| Utah | 13.37 | 3rd | $47 | 1,009 | 68 |
| Oklahoma | 14.33 | 9th | $50 | 897 | 30 |
| New Mexico | 15.06 | 14th | $53 | 611 | 27 |
| Arizona | 15.18 | 17th | $53 | 1,504 | 94 |
| Texas | 15.94 | 24th | $56 | 5,374 | 72 |
| Colorado | 17.13 | 29th | $60 | 1,687 | 97 |
How long the charge itself takes does not change with the state, only what it costs: the Tesla Model 3 charging time, Tesla Model Y charging time and Hyundai Ioniq 5 charging time are 28, 27 and 18 minutes from 10 to 80 per cent wherever you plug in, and each of those pages runs the same cost arithmetic as this one at the national average rate rather than New Mexico’s.
Frequently asked questions
How much does it cost to charge an electric car in New Mexico?
About $4.68 per 100 miles at home for the median EPA-rated car, $53 a month at 1,125 miles, using the EIA residential average of 15.06 cents per kWh. The most efficient car here, the Lucid Air Pure RWD, costs $39 a month; the least efficient, the GMC Hummer EV Pickup 3X, $110.
Is it cheaper to charge an EV than to buy petrol in New Mexico?
Yes. At 15.06 cents per kWh the median car costs $53 a month against $170 of petrol for a 27 mpg car at $4.07 a gallon — $117 a month in favour of New Mexico, $1,403 a year.
How many fast chargers are there in New Mexico?
611 plugs across 177 sites (AFDC, 2026-09-16) for 16,600 registered cars, which is 27 per plug and among the easiest ratios in the country. DC fast only — Level 2 is a different question.
Can a non-Tesla use a Tesla charger in New Mexico?
Where the site is open to other brands, yes, with the right adapter. 31 of the 177 fast-charging sites in New Mexico carry the NACS plug (18%) and 153 carry CCS1 (86%), so a CCS car still has the larger of the two networks to fall back on. The plug on each car is listed on its model page.
Which electric car is cheapest to charge in New Mexico?
The Lucid Air Pure RWD, at 23.1 kWh per 100 miles: $3.48 per 100 miles and $39 a month in New Mexico. Picking it over the GMC Hummer EV Pickup 3X is worth $71 a month here, which is as much as the New Mexico rate ever makes efficiency worth; the full efficiency order is the same in every state.
