Charging the median electric car at home in Utah costs about $47 a month at 13.37 cents per kilowatt-hour — the 3rd cheapest of 51 states. Cheap power is the whole argument for an electric car in Utah: the same miles burn $170 of petrol, so the meter saves $123 a month and $1,474 a year, and the state has one public fast-charging plug for every 68 electric cars registered in it.
What electricity costs in Utah
Electricity is cheap in Utah, and that is most of the story of what an electric car costs to run here. The EIA published residential average for Utah is 13.37 cents per kWh (June 2026), against a US average of 18.34. That puts Utah at 3rd 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 $4.16 per 100 miles, $47 a month, $561 a year.
The line where home charging stops beating petrol sits around 48 cents per kWh, at $4.07 a gallon and 27 mpg. Utah is below that line by 35.10 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 Utah
Efficiency is worth more in Utah than in most states: $63 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 13.37 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 Utah
Utah has 194 public DC fast-charging sites with 1,009 plugs in the federal AFDC station locator (2026-09-16), for 68,400 battery-electric cars registered in the state at the end of 2025.
Plug supply is the weaker half of the picture in Utah: 68 registered EVs for every public fast-charging plug where the typical state manages 55 — 37th of 51 states, fewest cars per plug first. Home charging carries more of the load here than the raw site count suggests.
31% of the sites in Utah have a single plug and the state averages 5.2 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 Utah with 48% of the plugs (484 of 1,009), the rest split among the other operators — enough competition that price and reliability are not one company decision.
Which plug fits in Utah
Neither plug has Utah to itself: 77% of sites carry CCS1 and 36% 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 Utah | Share of sites | Cars that use it |
|---|---|---|---|
| CCS1 (J1772 Combo) | 150 | 77% | Almost every non-Tesla EV sold in the US |
| NACS / J3400 (Tesla) | 69 | 36% | Teslas, and other cars with an adapter where the site allows it |
| CHAdeMO | 69 | 36% | Older Nissan Leaf and Mitsubishi only |
69 sites keep a CHAdeMO plug (36%). Useful if you drive an older Leaf in Utah; 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 Utah, and still under the $15.07 the petrol car spends on them. Anyone charging mostly in public in Utah 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.
Utah against its neighbours
Nevada is cheaper than Utah; Idaho, Wyoming, Colorado, New Mexico, Arizona are dearer. Same car in every row, so the columns are comparable: Utah is cheaper than 5 of the 6 states it touches.
| State | Cents / kWh | Rank | Chevrolet Equinox EV FWD / month | Fast plugs | EVs per plug |
|---|---|---|---|---|---|
| Nevada | 13.11 | 1st | $46 | 1,174 | 73 |
| Utah | 13.37 | 3rd | $47 | 1,009 | 68 |
| Idaho | 14.37 | 10th | $50 | 309 | 46 |
| New Mexico | 15.06 | 14th | $53 | 611 | 27 |
| Arizona | 15.18 | 17th | $53 | 1,504 | 94 |
| Wyoming | 15.24 | 18th | $53 | 169 | 11 |
| 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 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 Utah’s.
Frequently asked questions
How much does it cost to charge an electric car in Utah?
$4.16 per 100 miles at home, $47 a month over 1,125 miles, at Utah’s 13.37-cent rate. Across the database the answer runs from $35 for the Lucid Air Pure RWD to $98 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 Utah?
Yes. At 13.37 cents per kWh the median car costs $47 a month against $170 of petrol for a 27 mpg car at $4.07 a gallon — $123 a month in favour of Utah, $1,474 a year.
How many fast chargers are there in Utah?
194 sites and 1,009 plugs (AFDC, 2026-09-16), which 68,400 registered cars have to share — 68 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 Utah?
Where the site is open to other brands, yes, with the right adapter. 69 of the 194 fast-charging sites in Utah carry the NACS plug (36%) and 150 carry CCS1 (77%), 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 Utah?
The Lucid Air Pure RWD, at 23.1 kWh per 100 miles: $3.09 per 100 miles and $35 a month in Utah. Picking it over the GMC Hummer EV Pickup 3X is worth $63 a month here, which is as much as the Utah rate ever makes efficiency worth; the full efficiency order is the same in every state.
