Charging the median electric car at home in Texas costs about $56 a month at 15.94 cents per kilowatt-hour — the 24th cheapest of 51 states, and 13 per cent below the national average. Petrol over the same 1,125 miles costs $170, so the saving is $114 a month, $1,366 a year; on the public side 72 registered cars share each fast-charging plug, against 55 in the typical state.
What electricity costs in Texas
The EIA published residential average for Texas is 15.94 cents per kWh (June 2026), against a US average of 18.34. That puts Texas at 24th 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 $4.96 per 100 miles, $56 a month, $669 a year.
Against a 27 mpg car at $4.07 a gallon, electricity stops being the cheaper fuel at about 48 cents per kWh. Texas is below that line by 32.53 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 Texas
Efficiency is worth more in Texas than in most states: $75 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 Texas records. The four cars without a US rating are in kilometres on the national page.
Public fast charging in Texas
Texas has 883 public DC fast-charging sites with 5,374 plugs in the federal AFDC station locator (2026-09-16), for 387,400 battery-electric cars registered in the state at the end of 2025.
Plug supply is the weaker half of the picture in Texas: 72 registered EVs for every public fast-charging plug where the typical state manages 55 — 39th of 51 states, fewest cars per plug first. Home charging carries more of the load here than the raw site count suggests.
Sites here are mostly multi-plug: only 22% have a single charger, and the state averages 6.1 plugs per site. A stop being occupied is far less often a dead end in Texas than the national picture suggests.
Tesla is the largest network in Texas with 53% of the plugs (2,829 of 5,374), the rest split among the other operators — enough competition that price and reliability are not one company decision.
Which plug fits in Texas
Neither plug has Texas to itself: 78% of sites carry CCS1 and 42% carry the Tesla NACS connector. Most drivers will meet both on a long route, which is the position the rest of the country is moving towards as manufacturers switch to NACS.
| Connector | Sites in Texas | Share of sites | Cars that use it |
|---|---|---|---|
| CCS1 (J1772 Combo) | 685 | 78% | Almost every non-Tesla EV sold in the US |
| NACS / J3400 (Tesla) | 370 | 42% | Teslas, and other cars with an adapter where the site allows it |
| CHAdeMO | 197 | 22% | Older Nissan Leaf and Mitsubishi only |
197 sites keep a CHAdeMO plug (22%). Useful if you drive an older Leaf in Texas; irrelevant to everything else on this page, and the count falls every year as sites are refitted.
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 — 3.0 times what the same miles cost at home in Texas, and still under the $15.07 the petrol car spends on them. Anyone charging mostly in public in Texas should read the home column as optimistic by a factor of 3.0 — 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.
Texas against its neighbours
Every state on Texas’s borders is cheaper: New Mexico at 15.06, Oklahoma at 14.33, Arkansas at 14.12, Louisiana at 13.49 cents. The monthly column is the Chevrolet Equinox EV FWD in every row, which makes the border differences directly comparable — $9 a month separates Texas from its cheapest neighbour.
| State | Cents / kWh | Rank | Chevrolet Equinox EV FWD / month | Fast plugs | EVs per plug |
|---|---|---|---|---|---|
| Louisiana | 13.49 | 4th | $47 | 410 | 55 |
| Arkansas | 14.12 | 7th | $49 | 287 | 43 |
| Oklahoma | 14.33 | 9th | $50 | 897 | 30 |
| New Mexico | 15.06 | 14th | $53 | 611 | 27 |
| Texas | 15.94 | 24th | $56 | 5,374 | 72 |
How long the charge itself takes does not change with the state, only what it costs: the Hyundai Ioniq 6 charging time, Kia EV6 charging time and Kia EV9 charging time are 17, 17 and 22 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 Texas’s.
Frequently asked questions
How much does it cost to charge an electric car in Texas?
About $4.96 per 100 miles at home for the median EPA-rated car, $56 a month at 1,125 miles, using the EIA residential average of 15.94 cents per kWh. The most efficient car here, the Lucid Air Pure RWD, costs $41 a month; the least efficient, the GMC Hummer EV Pickup 3X, $117.
Is it cheaper to charge an EV than to buy petrol in Texas?
Yes. At 15.94 cents per kWh the median car costs $56 a month against $170 of petrol for a 27 mpg car at $4.07 a gallon — $114 a month in favour of Texas, $1,366 a year.
How many fast chargers are there in Texas?
883 sites and 5,374 plugs (AFDC, 2026-09-16), which 387,400 registered cars have to share — 72 per plug, against 55 in the median state. Only DC fast chargers are counted; Level 2 is not.
Can a non-Tesla use a Tesla charger in Texas?
Where the site is open to other brands, yes, with the right adapter. 370 of the 883 fast-charging sites in Texas carry the NACS plug (42%) and 685 carry CCS1 (78%), 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 Texas?
The Lucid Air Pure RWD, at 23.1 kWh per 100 miles: $3.68 per 100 miles and $41 a month in Texas. Picking it over the GMC Hummer EV Pickup 3X is worth $75 a month here, which is as much as the Texas rate ever makes efficiency worth; the full efficiency order is the same in every state.
