Why the cost differs in North Dakota

North Dakota has the 6th cheapest residential electricity of the 51 US states and territories we track, at 13.61¢ per kWh against a national average of 18.44¢. That is -26.2% compared with the national figure. North Dakota has the cheapest electricity in the country, built on abundant coal, strong wind resources and hydroelectric imports spread across a very small population. Retail service is regulated. Winter is severe and sustained, making heating the dominant load by a wide margin, and the low rate means high-consumption heating appliances cost less to run here than anywhere else in the nation.

For this appliance specifically, the difference works out to a saving of $381 a year against what the same ev charger (level 2) would cost at the national average rate. Run the identical appliance in Hawaii and it would cost $4,100 a year; in Idaho it would cost $974. That spread of $3,126 is entirely down to location.

At North Dakota's rate this single ev charger (level 2) accounts for roughly 75% of a typical household's entire annual electricity bill. It is not a rounding error on your statement - it is one of the largest single line items in it.

Electricity in North Dakota is cheap by national standards, which cuts both ways: running this ev charger (level 2) costs less than it would almost anywhere else, but the payback period on an efficiency upgrade is correspondingly longer. Replacing a working unit purely to save energy is harder to justify here.

Retail service in North Dakota is regulated, so most households pay a tariff set through state rate cases rather than a shopped rate. The state average is a reasonable proxy, though your utility's specific tariff still varies.

About running a ev charger (level 2)

A Level 2 charger draws 3.3 to 11.5 kilowatts. Because charging usually happens overnight, time-of-use rates matter enormously - off-peak charging can halve the effective cost in states with time-varying tariffs.

What actually changes the cost

  • At typical use this is a major load - around 7,884 kWh a year. Efficiency upgrades here pay back faster than on any small appliance.
  • Models vary widely, from about 3300W to 11500W. Check the nameplate on your own unit rather than assuming an average, because the spread is more than 2x.
  • If your utility offers time-of-use pricing, shifting this load off-peak can cut its cost substantially without using any less energy.

How we worked this out

The arithmetic is simple and we would rather show it than hide it. Divide watts by 1,000 to get kilowatts, multiply by hours of use and by the duty cycle to get kilowatt-hours, then multiply by your rate:

7200W ÷ 1000 × 3h = 21.600 kWh/day × 13.61¢ = $2.940 per day

One honest caveat: North Dakota’s figure is a state average published by the EIA. Your own utility’s tariff, any time-of-use pricing, fixed monthly service charges and local taxes all shift the real number. Put your actual per-kWh rate into the calculator above for a figure that reflects your bill.

Questions about ev charger (level 2) running costs

How many watts does a ev charger (level 2) use?

A typical ev charger (level 2) draws about 7200 watts while running, with most models falling between 3300W and 11500W. Check the nameplate label or manual for your specific unit - the range is wide enough that averages can mislead.

How much electricity does a ev charger (level 2) use per day?

At around 3 hours of use a day and a 100% duty cycle, that works out to roughly 21.6 kWh per day, or about 648 kWh a month. Your actual figure depends on your usage and model.

Why does the cost differ so much between states?

Residential electricity rates across the US range from about 12.35 cents per kWh in North Dakota to 46.62 cents in Hawaii - nearly a fourfold difference. The same ev charger (level 2), used identically, therefore costs almost four times as much to run in the most expensive state as in the cheapest.

Is it cheaper to run a ev charger (level 2) at night?

Only if you are on a time-of-use or variable tariff. On a flat rate, the time of day makes no difference to cost. If you are on time-of-use pricing, off-peak hours are typically materially cheaper, and shifting this load can reduce its cost without reducing usage.
