Charging the median electric car at home in Colorado costs about $60 a month at 17.13 cents per kilowatt-hour — the 29th cheapest of 51 states, and 7 per cent below the national average. Petrol over the same 1,125 miles costs $170, so the saving is $110 a month, $1,316 a year; on the public side 97 registered cars share each fast-charging plug, against 55 in the typical state.
Public fast charging in Colorado
Colorado has 498 public DC fast-charging sites with 1,687 plugs in the federal AFDC station locator (2026-09-16), for 162,800 battery-electric cars registered in the state at the end of 2025.
Colorado is one of the most crowded states in the country per plug: 162,800 registered EVs share 1,687 public fast-charging plugs, 97 cars each where the typical state manages 55 — 46th of 51. If you cannot charge where you sleep, that number is the one to weigh before buying.
Nearly half of those sites stand alone: 50% of Colorado fast-charging locations have exactly one plug, so an occupied or broken charger means driving on rather than waiting behind one car. The state averages 3.4 plugs per site.
No operator dominates Colorado: the largest, Tesla, holds 37% of the plugs (630 of 1,687). That is a more competitive market than most states, and it also means more apps and accounts to keep.
Which plug fits in Colorado
The plug question in Colorado has a clear answer: 91% of the sites carry CCS1, the connector on almost every non-Tesla EV sold in the US, against 26% 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 Colorado | Share of sites | Cars that use it |
|---|---|---|---|
| CCS1 (J1772 Combo) | 454 | 91% | Almost every non-Tesla EV sold in the US |
| NACS / J3400 (Tesla) | 127 | 26% | Teslas, and other cars with an adapter where the site allows it |
| CHAdeMO | 247 | 50% | Older Nissan Leaf and Mitsubishi only |
CHAdeMO is unusually well represented here: 50% of Colorado’s sites still carry it (247 of 498). 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 — 2.8 times what the same miles cost at home in Colorado, and still under the $15.07 the petrol car spends on them. Anyone charging mostly in public in Colorado should read the home column as optimistic by a factor of 2.8 — 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 Colorado
The EIA published residential average for Colorado is 17.13 cents per kWh (June 2026), against a US average of 18.34. That puts Colorado at 29th 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 Colorado that is $5.33 per 100 miles and $719 over a year, $-4 a month more than the same car would cost at the national average rate.
Against a 27 mpg car at $4.07 a gallon, electricity stops being the cheaper fuel at about 48 cents per kWh. Colorado is below that line by 31.34 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 Colorado
Efficiency is worth more in Colorado than in most states: $81 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.

Every kWh above is measured at the wall. At 17.13 cents the charging losses alone cost the median driver about $5 a month in Colorado — a real line on the bill, and the reason this site does not quote battery-size arithmetic. Four cars have no US rating; they are in kilometres on the national page.
Colorado against its neighbours
Every state on Colorado’s borders is cheaper: Wyoming at 15.24, Nebraska at 13.25, Kansas at 15.71, Oklahoma at 14.33, New Mexico at 15.06, Utah at 13.37, Arizona at 15.18 cents. The monthly column is the Chevrolet Equinox EV FWD in every row, which makes the border differences directly comparable — $14 a month separates Colorado from its cheapest neighbour.
| State | Cents / kWh | Rank | Chevrolet Equinox EV FWD / month | Fast plugs | EVs per plug |
|---|---|---|---|---|---|
| Nebraska | 13.25 | 2nd | $46 | 282 | 42 |
| 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 |
| Wyoming | 15.24 | 18th | $53 | 169 | 11 |
| Kansas | 15.71 | 22nd | $55 | 382 | 49 |
| 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 Kia EV9 charging time, Volkswagen ID.4 charging time and Volkswagen ID.7 charging time are 22, 28 and 27 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 Colorado’s.
Frequently asked questions
How much does it cost to charge an electric car in Colorado?
About $5.33 per 100 miles at home for the median EPA-rated car, $60 a month at 1,125 miles, using the EIA residential average of 17.13 cents per kWh. The most efficient car here, the Lucid Air Pure RWD, costs $45 a month; the least efficient, the GMC Hummer EV Pickup 3X, $125.
Is it cheaper to charge an EV than to buy petrol in Colorado?
Yes. At 17.13 cents per kWh the median car costs $60 a month against $170 of petrol for a 27 mpg car at $4.07 a gallon — $110 a month in favour of Colorado, $1,316 a year.
How many fast chargers are there in Colorado?
498 sites and 1,687 plugs (AFDC, 2026-09-16), which 162,800 registered cars have to share — 97 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 Colorado?
Where the site is open to other brands, yes, with the right adapter. 127 of the 498 fast-charging sites in Colorado carry the NACS plug (26%) and 454 carry CCS1 (91%), 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 Colorado?
The Lucid Air Pure RWD, at 23.1 kWh per 100 miles: $3.96 per 100 miles and $45 a month in Colorado. Picking it over the GMC Hummer EV Pickup 3X is worth $81 a month here, which is as much as the Colorado rate ever makes efficiency worth; the full efficiency order is the same in every state.
