Charging the median electric car at home in New Hampshire costs about $95 a month at 27.01 cents per kilowatt-hour, 47 per cent above the national average — the 44th cheapest of 51 states. It still beats the $170 a petrol car costs over the same 1,125 miles, by $75 a month, but New Hampshire is close enough to the break-even that the tariff you are on matters more than the car you buy.
What electricity costs in New Hampshire
New Hampshire is one of the ten most expensive places in the country to buy a kilowatt-hour, which changes the arithmetic before any car is chosen. The EIA published residential average for New Hampshire is 27.01 cents per kWh (June 2026), against a US average of 18.34. That puts New Hampshire at 44th of 51 states and DC, cheapest first — the dearer half of the country. The Chevrolet Equinox EV FWD sits in the middle of the 36 cars rated here at 31.1 kWh per 100 miles; in New Hampshire that is $8.40 per 100 miles and $1,134 over a year, $30 a month more than the same car would cost at the national average rate.
Petrol wins once electricity passes roughly 48 cents per kWh — the figure worth knowing in a dear state. New Hampshire is below that line by 21.46 cents, so the saving holds at the state-average rate before any overnight tariff is applied. A summer peak on top of 27.01 cents can push a New Hampshire household past the break-even on its own, which is why the average is a floor to argue from rather than a figure to rely on. Put your real tariff into the running-cost calculator.
Every EPA-rated car, charged at home in New Hampshire
At the New Hampshire average rate, one car in the database costs more to charge than the petrol car costs to fuel: GMC Hummer EV Pickup 3X. Everything above $170 a month in the table is in that position; everything below it saves money at the meter.

At New Hampshire prices the roughly ten per cent lost in the charger and cable is worth about $9 a month on its own, which is why these are EPA ratings measured at the socket rather than pack-size arithmetic. The four cars with no US rating are in kilometres on the national page.
Public fast charging in New Hampshire
New Hampshire has 81 public DC fast-charging sites with 346 plugs in the federal AFDC station locator (2026-09-16), for 16,100 battery-electric cars registered in the state at the end of 2025.
There are 47 registered EVs for every public fast-charging plug in New Hampshire, a little below the 55 of the typical state — 20th of 51 states, fewest cars per plug first. Plug supply is roughly keeping pace with the cars here.
40% of the sites in New Hampshire have a single plug and the state averages 4.3 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 New Hampshire with 54% of the plugs (186 of 346), the rest split among the other operators — enough competition that price and reliability are not one company decision.
Which plug fits in New Hampshire
Neither plug has New Hampshire to itself: 75% of sites carry CCS1 and 31% 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 New Hampshire | Share of sites | Cars that use it |
|---|---|---|---|
| CCS1 (J1772 Combo) | 61 | 75% | Almost every non-Tesla EV sold in the US |
| NACS / J3400 (Tesla) | 25 | 31% | Teslas, and other cars with an adapter where the site allows it |
| CHAdeMO | 31 | 38% | Older Nissan Leaf and Mitsubishi only |
31 sites keep a CHAdeMO plug (38%). Useful if you drive an older Leaf in New Hampshire; 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 — 1.8 times what the same miles cost at home in New Hampshire, and still under the $15.07 the petrol car spends on them. The multiple is unusually small here, because New Hampshire’s residential rate is already close to network pricing; public charging costs less of a premium than it does in most of the country. How long each car takes on a fast charger is on its charging page.
New Hampshire against its neighbours
Vermont is cheaper than New Hampshire; Maine, Massachusetts are dearer. Same car in every row, so the columns are comparable: New Hampshire is cheaper than 2 of the 3 states it touches.
| State | Cents / kWh | Rank | Chevrolet Equinox EV FWD / month | Fast plugs | EVs per plug |
|---|---|---|---|---|---|
| Vermont | 24.44 | 42nd | $86 | 319 | 37 |
| New Hampshire | 27.01 | 44th | $95 | 346 | 47 |
| Maine | 29.59 | 48th | $104 | 435 | 27 |
| Massachusetts | 29.61 | 49th | $104 | 1,971 | 58 |
How long the charge itself takes does not change with the state, only what it costs: the Volkswagen ID.7 charging time, Ford Mustang Mach-E charging time and BMW i4 charging time are 27, 32 and 28 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 Hampshire’s.
Frequently asked questions
How much does it cost to charge an electric car in New Hampshire?
More than in most of the country: $8.40 per 100 miles, $95 a month for the median car at 27.01 cents per kWh. The Lucid Air Pure RWD brings that down to $70; the GMC Hummer EV Pickup 3X pushes it to $198, and in New Hampshire that choice is worth $128 a month.
Is it cheaper to charge an EV than to buy petrol in New Hampshire?
Yes. At 27.01 cents per kWh the median car costs $95 a month against $170 of petrol for a 27 mpg car at $4.07 a gallon — $75 a month in favour of New Hampshire, $901 a year.
How many fast chargers are there in New Hampshire?
81 public DC fast-charging sites and 346 plugs in the AFDC locator as of 2026-09-16, for 16,100 registered EVs — 47 cars per plug. Level 2 chargers are not counted here; only DC fast.
Can a non-Tesla use a Tesla charger in New Hampshire?
Where the site is open to other brands, yes, with the right adapter. 25 of the 81 fast-charging sites in New Hampshire carry the NACS plug (31%) and 61 carry CCS1 (75%), 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 Hampshire?
The Lucid Air Pure RWD, at 23.1 kWh per 100 miles: $6.24 per 100 miles and $70 a month in New Hampshire. Picking it over the GMC Hummer EV Pickup 3X is worth $128 a month here, which is as much as the New Hampshire rate ever makes efficiency worth; the full efficiency order is the same in every state.
