Charging the median electric car at home in Louisiana costs about $47 a month at 13.49 cents per kilowatt-hour — the 4th cheapest of 51 states. Cheap power is the whole argument for an electric car in Louisiana: the same miles burn $170 of petrol, so the meter saves $122 a month and $1,469 a year, and the state has one public fast-charging plug for every 55 electric cars registered in it.
What electricity costs in Louisiana
Electricity is cheap in Louisiana, and that is most of the story of what an electric car costs to run here. The EIA published residential average for Louisiana is 13.49 cents per kWh (June 2026), against a US average of 18.34. That puts Louisiana at 4th 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 $4.20 per 100 miles, $47 a month, $566 a year.
The line where home charging stops beating petrol sits around 48 cents per kWh, at $4.07 a gallon and 27 mpg. Louisiana is below that line by 34.98 cents, so the saving holds at the state-average rate before any overnight tariff is applied. The state average is already low enough that a time-of-use plan changes the answer by a few dollars rather than reversing it; the running-cost calculator will show you the few dollars.
Every EPA-rated car, charged at home in Louisiana
Efficiency is worth more in Louisiana than in most states: $64 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.

The kWh figures are EPA combined ratings measured at the wall, so charger and cable losses are already inside them. Working from battery size instead would have shaved about a tenth off every number above — small money at 13.49 cents, but the same tenth that decides the close rows. Four cars have no US rating and appear in kilometres on the national page.
Public fast charging in Louisiana
Louisiana has 94 public DC fast-charging sites with 410 plugs in the federal AFDC station locator (2026-09-16), for 22,600 battery-electric cars registered in the state at the end of 2025.
There are 55 registered EVs for every public fast-charging plug in Louisiana, a little above the 55 of the typical state — 26th of 51 states, fewest cars per plug first. Plug supply is roughly keeping pace with the cars here.
33% of the sites in Louisiana have a single plug and the state averages 4.4 plugs per site — enough that a busy stop usually has another bay, not enough to count on it off the interstate.
Tesla is the largest network in Louisiana with 54% of the plugs (223 of 410), the rest split among the other operators — enough competition that price and reliability are not one company decision.
Which plug fits in Louisiana
The plug question in Louisiana has a clear answer: 81% of the sites carry CCS1, the connector on almost every non-Tesla EV sold in the US, against 24% 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 Louisiana | Share of sites | Cars that use it |
|---|---|---|---|
| CCS1 (J1772 Combo) | 76 | 81% | Almost every non-Tesla EV sold in the US |
| NACS / J3400 (Tesla) | 23 | 24% | Teslas, and other cars with an adapter where the site allows it |
| CHAdeMO | 26 | 28% | Older Nissan Leaf and Mitsubishi only |
26 sites keep a CHAdeMO plug (28%). Useful if you drive an older Leaf in Louisiana; 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 — 3.6 times what the same miles cost at home in Louisiana, and still under the $15.07 the petrol car spends on them. Anyone charging mostly in public in Louisiana should read the home column as optimistic by a factor of 3.6 — 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.
Louisiana against its neighbours
Every state on Louisiana’s borders charges more per kilowatt-hour — Louisiana is the cheapest place to plug in on this map. Crossing a border to charge is not a saving anyone in Louisiana can make; the monthly column is the Chevrolet Equinox EV FWD throughout, so the rows line up with every other state page here.
| 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 |
| Mississippi | 14.88 | 12th | $52 | 345 | 21 |
| 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 Ford Mustang Mach-E charging time, BMW i4 charging time and Porsche Taycan charging time are 32, 28 and 19 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 Louisiana’s.
Frequently asked questions
How much does it cost to charge an electric car in Louisiana?
$4.20 per 100 miles at home, $47 a month over 1,125 miles, at Louisiana’s 13.49-cent rate. Across the database the answer runs from $35 for the Lucid Air Pure RWD to $99 for the GMC Hummer EV Pickup 3X — a narrow spread, because the rate is low.
Is it cheaper to charge an EV than to buy petrol in Louisiana?
Yes. At 13.49 cents per kWh the median car costs $47 a month against $170 of petrol for a 27 mpg car at $4.07 a gallon — $122 a month in favour of Louisiana, $1,469 a year.
How many fast chargers are there in Louisiana?
94 public DC fast-charging sites and 410 plugs in the AFDC locator as of 2026-09-16, for 22,600 registered EVs — 55 cars per plug. Level 2 chargers are not counted here; only DC fast.
Can a non-Tesla use a Tesla charger in Louisiana?
Where the site is open to other brands, yes, with the right adapter. 23 of the 94 fast-charging sites in Louisiana carry the NACS plug (24%) and 76 carry CCS1 (81%), 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 Louisiana?
The Lucid Air Pure RWD, at 23.1 kWh per 100 miles: $3.12 per 100 miles and $35 a month in Louisiana. Picking it over the GMC Hummer EV Pickup 3X is worth $64 a month here, which is as much as the Louisiana rate ever makes efficiency worth; the full efficiency order is the same in every state.
