EV power consumption a costly mystery

By David Wojick

This article is about questions not answers. When it comes to understanding the electric power grid there is a big data gap that needs to be overcome. We have no actual data on how much electricity EVs consume or when and where they consume it.

The problem is that most EVs most of the time are charged at the owner’s residence or workplace. In both cases the electricity consumed is often simply added to that building’s total on the meter. There is no separate accounting for it so no data. There are about 7,000,000 EVs on the American road with unknown grid impacts.

We do have a government guess to a preposterous eight significant figures, based on a computer model. But there is no way to test or calibrate the model so there is no reason to believe its output.

Still we can use these conjectured numbers to make some basic points about EV power and energy usage. We will treat them as true for the moment. They are from EIA here.

Estimated total EV energy consumption for the last three years is this:

2025 = 23,532,855 MWh 2024 = 17,800,214 MWh 2023 = 13,212,000 MWh

Note that the number almost doubled in just two years. That is remarkable growth especially when people talk about the EV market being dead.

Still even the biggest number is just a tiny fraction of U.S. electric energy consumption. As a result many articles say it shows that EVs have little or no grid impact. That conclusion is seriously wrong because there is more to the grid than total annual statistics.

What mostly challenges the grid is power not energy, MW not MWh, especially peak demand. Here EVs can have a significant impact because they are in effect peak demand generators.

The typical EV only charges for a very small fraction of the time so the charge rate is quite large. In fact there is a tremendous effort to develop ever faster charging which makes the charge peak even bigger.

When lots of EVs charge at the same time the combined peak demand can be very significant. It is the impact of a lot of EVs charging at the same time that we need to understand.

Here is a wildly worst case scenario that that makes the potential impact clear. First let’s assume all the 7 million or so EVs charge at the same time. Second let’s say they charge three times a week and it takes just a half hour each time, with a constant charge rate. (This short time is reasonable because most will just be topping off to get a full charge.)

Taking the 2025 number at a round 24,000,000 MWh, that amount is drawn from the grid in 156 hours. The charge rate is just under 154,000 MW.

This is a huge demand. In fact it is roughly equal to the record peak demand at PJM which serves 67 million customers. Demand like this would quickly fry the grid.

Of course the reality is far more complex and nothing even remotely like this has ever happened. But there are only so many hours a day and most of those 7 million EVs have to be charged fairly often.

The big question is what do the potential many-EV combined peaks look like at a realistic scale? They may already be a problem at the local level.

While the reliability problem may yet be small the cost problem might already be big. It has long been claimed that many local power distribution networks will need to be upgraded to provide the capacity to handle EV charging.

Upgrading is expensive and if there is a lot going it it might be a significant component of the present price increases. Is there a correlation between EV registrations and electricity price increases?

The fact that EV power usage is invisible could be hiding problems that are serious and rapidly growing. We really need to understand what is going on.

This may be a stupid question, but why does it matter that huge peaks in energy usage derive from EV charging? The electricity needs to be generated no matter if it is for charging a battery or running a hot water heater, electric furnace, electric dryer and oven after work.

You do know that many municipalities have been mandating gas to electric conversions? Home/Business EV charging can be regulated to only permit charging at non-peak times, whereas that is much more difficult to force compliance when it comes to doing a day’s worth of household chores between coming home from work and calling it a night.

We largely have converted into a low trust society, and one of the features of that cultural model is that people give absolutely no thought to their actions as it relates to others, so there can’t even be a gentlemen’s agreement to find ways to “flatten the curve”.

Might as well plan at the social level for a peaky grid and personally for rolling brown/black outs until the whole thing ends up like Cuba where only the Politically Connected get premium electrical service.

So long as you have constant reliable energy feeding into the grid it doesn’t matter much but, when reliable energy generation is removed from the grid leaving weather dependent generation as the only choice, and the grid becomes unreliable in turn, then it really matters when you charge your EV as peak times might have little available capacity to do so.

Oops forgot the most important caveat when it comes to electricity generating…
Constant, Reliable, and Dispatchable. Wind and Solar aren’t dispatchable and so can’t be increased when demand increases.
With Wind and Solar you only get the fuel when Nature decides to deliver it AND, unlike Oliver, you can’t ask for more.

If your local gas state can still pump during a power outage it is likely because they have a Diesel Generator parked near by.
Back in the 30’s they certainly could but you had to hand pump the gas up into the pump’s reservoir first, before dispensing it into your tank

It matters because supply doesn’t just “happen”, it has to be generated and that takes both equipment and fuel. Both have to be available when and where they are needed.
This is true regardless of what you are using to create the power, however it is a lot worse when the supply is also unpredictable.

It is because the Grid (the generation connected) has a maximum power output, and this cannot be exceeded. There is not sufficient driving power available, just like your car trying to accelerate up a steep hill. The effect of this is that the voltage falls, and circuits trip out as they are overloaded, and the problem gets worse very quickly. Our normal method to fix this is called hot or rotating reserve, whole power stations running with no load ready for increasing demand. Wind and solar cannot do this, because they are always run at the full power available, and no one wants to pay for conventional stations to run with no load. Simple enough but critical to 24/7 electricity! Also a large conventional power station has a huge rotating mass, and this stored energy covers the peaky nature of the load, but this is a secondary consideration.

“no one wants to pay for conventional stations to run with no load”

But those same people seem to be agreeable to paying to curtail electrical generation that exceeds demand (WTG & SV).

The curtailments are at retail prices (other terms are also used).
Power stations running with no load is fuel and labor costs, which is less than the retail prices.

So we either way we pay extra when load is low.

” … but why does it matter that huge peaks in energy usage derive from EV charging?”

Maybe it’s because time of the charging (demand) is important when planning electric grids. Gasoline stations have lots of pumps — enough for morning and evening rush — more than would be needed if the demand was constant all day and all night … weekdays and week ends.

Private EVs are/will likely be charged overnight when grid demand is otherwise low and most people are sleeping — so no fatter wires to homes needed. Related is this story from the UK …

Why the UK Grid Had to Prepare for TV ShowsThe National Grid’s Energy Balancing Team literally studied:

  • TV schedules
  • Soap‑opera storylines
  • Expected cliffhangers
  • Sports match pacing

They used historical data and forecasting models to predict spikes and bring fast‑response power sources online (like pumped‑storage hydro).

The points you raise certainly require discussion.

Some are, IMHO, a bit off the mark, but the point about electrifying everything fits in well with the EV demand discussion and we could end up (I hope not) with a heat pump in every house and an EV in every garage type of world.

Part of the issue of your stated cultural model is people have been trained to let the government do the thinking for them. As more government control is imposed, less critical thinking by the public will happen.

And yes, we see it today, the Political Elite build mansions on ocean property while telling us the ocean is going to drown us. Those elite consume electricity at rates equal to multiples of individuals.

It’s not just about generation, it’s also about distribution. The transformer that feeds your home likely feeds several others as well. It was sized based on typical household loads. If everyone in the homes around you converts to electric vehicles, electric stoves, electric heating, etc., the pole transformer may be too small which can lead to overheating and failure.

I moved into a new development a bit over a year ago. The homes are not wired for 220v so even if I wanted a an EV it would be impractical as I would have to charge it off a 110v outlet. Basically that’s a waste of time. My BIL does this but he lives 1 mile from work and I think he said he charges at something like 4 miles per hour. If he has to make a longer trip he drives over to the single charging station in town, crosses his fingers that a) it’s working and b) no in use already to get a full charge.

Work did make provisions for a charging station but its never been installed and likely never will be.

It matters because power is not magically created, nor is it magically transported from where it is created to where it is needed.

Power generation also has to be planned, so that the equipment necessary is available, when it is needed. Large changes in total demand as well as the timing of that demand, have to be adapted to.
As for where the demand is, do you believe the existing power lines have infinite capacity? Because if you do, they don’t. As demand goes up, more and bigger lines have to be built to handle the new load.

I think what would be most ideal, would be a dedicated grid network connected to every solar and wind farm in every State or across America. This Renewable grid network would have batteries located and connected to this grid network. This network would be live and also charging all these batteries every day when the sun is shining (it doesn’t shine everywhere, so that’s why they are sharing) and the wind is blowing. Then all the EV Charging locations across America would be connected to this Renewable Grid Network.
The great thing about this is our other national grid would have less power needed to transmit at this time. All EV’s in America that charge at a EV Charging station would have all the power they need as long as their batteries have enough stored. If by weather chance the batteries start running low, the worst thing would be that it’s time to park until the sun comes up in the morning and or the wind starts blowing.
I think this would be a great way to solve all electrical challenges at this time.

Yet…

So double the grid by duplicating new right of way (or digging up a LOT to lay down another line), new towers, new transformers, new meters, and somehow no one cheats and plays arbitrage with the competing grids. At least $2.3 Trillion for the US or about 8% of the GDP. And how many years to accomplish this? 30? 50? Because whole no industries need to come on-line for the raw materials, the manufactured goods and the installation. This will also be profoundly political so quadruple that estimate for the expected California/Minnesota/NY levels of fraud and grift with only Party Members being served (if anyone receives anything at all). The engineering would be outsourced to India, the mining to some third world, and China experiences a windfall in transformation manufacture. So you get third-world engineering and product quality made by low trust people who are looking for ways to game the system.

Then there is the cost in terms of energy, from extraction, refining, manufacturing, transporting, deploying etc. Totally negating the whole economic purpose of building a side-by-side infrastructure.

At this scale, millions of people are taken off-line from whatever productive life they had (its near 100% guarantee that the current crop of welfare deadbeats would not participate due to low IQ, drugs, criminal/predator behavior, zero work ethic, disabilities, sloth, etc.

And back to Why? Who benefits? With White Erasure and Replacement Theory, this is all built on debt that will never be paid to be gifted to a nation economic opportunity zone of third-world savages and drug addicts and their socialist overlords?

A concept worthy of discussion.

I do not believe for a variety of reasons it is practical.
It does however, eliminate the need for inverters since DC is involved in all aspects.
The real kicker is the size of the infrastructure batteries and the very real hazards they create.
The economics others have already addressed.

The other downside is having to wait until the sun rises or the wind blows. That would require every charging station to also have a motel connected to the AC grid, which will add demand.
A family on vacation, instead of a 15 minute stop for fuel, would have up to half a day per recharging added to their travel which results in an equivalent loss of time at the destination.
Consider also cargo transportation and the resulting hike in prices. Drivers get paid.
Consider also the impact on EMT vehicles. “Can’t get to the fire until morning, sorry.”

Well, in the end it is all about who controls what and the aim of the state and private companies is to take that away from the consumer as much as possible while at the same time pushing the idea that the consumer is taking control ( lowering thermostats, only use electricity at non peak hours etc). First by asking, then by regulating, always on the heel of some form of emergency. So we get what we got during Covid19. To keep us ‘safe’. Bring in QR codes, Digital IDs and CBDCs, Stablecoins to control it even more.
Use people’s mobile devices to control access.( Apple in the UK has basically forced people to identify themselves via Digi ID in their latest update, without the state actually forcing them to!!
Think about that for a minute.
Make mobile devices essential for everything, then take control of the system via personalisation. And soon enough PCs will require the same thing and yr old system will be rejected.
Your energy ( grid, home solar) and transportation (cars)system will only work when online.
So, better install a home system that still functions independently without the need to be online while you can.
There is a reason why generators are flying out the door. And people are stocking up on fuel and food. Get enough wood and a woodburning stove before the state completely regulates stuff. This is no longer paranoia..

AC must generate peaks, sure. But they usually are not anywhere this high-powered.
More to the point, between air being heated by sunlight rather asynchronously (even if they were all facing the sunrise, the top floors see it first), AC temperatures set differently and heat exchange rates of the houses being not the same, the initial peak front must be blurred. After that, it depends on how much power is really consumed.
Building-scale ventilators+AC may be more prone to it, but those are strangely uncommon. As if the goose-steppers for some reason missed the few areas where economy of scale could actually help.

AC generally presents a constant demand once the initial momentary surge during power on clears.

EV batteries are high demand step functions lasting much longer.
In addition, not everyone coordinates their AC turn on at the same moment, so those minor turn on surges are statistically distributed.
EV charging does not fit that model.

AC was introduced gradually, over the course of 30 to 40 years.
It was also gradual.
At first, only a few companies (such as movie theaters) had AC.
Then gradually the richer people were able to afford room AC units.
Then gradually more people had window units.
Then gradually, the rich started installing whole house units.
Over time, the number of homes using them gradually increased.

.

There was never a sudden jump in demand such as the socialists desire to force everyone into EVs over a few years time. While at the same time forcing everyone to use electric stoves, electric water heaters and heat pumps during the winter.

BTW, the amount of energy needed to charge all those EVs is several times what is being used now, and that is before you factor in electric water heaters and heat pumps.

You are going to need a massive investment in new infrastructure.

It isn’t that EVs have little impact, EVs are only a small percentage of the entire market so having little current impact is to be expected. BUT if they were half the market their impact would increase by a significant amount.
Much like saying Wind Turbines have little impact in avian life compared to Cats. There are only 400,000 – 500,000 turbines globally but there are 600,000,000 cats. Though I have yet to see a house cat take down an Eagle or even a Hawk. Those interact are generally not good for the cat.
Like Wind Turbines vs Cats, current EVs vs potential impacts to the grid is just a matter of ratio. Increase EV exposure, increase grid destabilization possibility.

The problem with Solar is that it only produces anything near capacity for 4 hours a day. There’s 2 hour ramp up time in the morning from 8-10am and an equal drop off in the afternoon from 2-4pm. So with solar you need to gather your 24 hours worth of need basically from 10am until 2pm on sunny days thus you need sufficient capacity to allow use from 10-2pm plus sufficient overcapacity to recharge your night time battery storage in the same amount of time. Solar-Plus-Battery is the only way to make Solar Power available at night during Peak Demand. And you need massive amounts of panels solely dedicated to recharging TWhs of Batteries in 4 hours.

Don’t forget the infrastructure required to get those TWhs from the panels to the batteries in 4 hours.

Not to mention pumping all that energy into those batteries in just 4 hours is going to generate a lot of heat. So at a minimum you are going to need to use some of that power the keep some mighty big fans running. Those fans will have to keep running long after the charging stops as first the heat from charging still needs to dissipate as well as the heat from drawing down the batteries needs to be dissipated at the same time.

A couple of things: (1) There are ways for an agency to get at the power usage information, if it were so motivated. DMV knows the addresses of most EVs at private homes. Somebody in the power company or state could get power usage by area, know how many EVs are in the area, and monitor usage from area to area. If also could get house sizes for each area to correct for the likely greater usage of power by larger houses, especially in the summer. From collective information for a metro area one might get his/her arms around answers to the question. (2) Avoiding concentration of cars charging at the same time: For cars charged at home, they could be put on an Internet enabled schedule. The owner inputs default garage times, which can be overridden, then the power company could control when the car is charged. This could be largely invisible to the car owner (unless the power company messes up — then, there’s always Uber). It’s no different than the power company controlling the temperature of your AC (if you allow it — that’s the way it works in my state). The technology just needs to be implemented. There is another thing: (3) Building out and strengthening the grid strike me as the most important priorities, rather than making investments in wind and solar the priorities for the power companies. Yes, we need more information to make intelligent decisions, but prioritizing grid over renewables is an easy call.

Coercing us to give up our freedoms (and privacy) makes us less safe.

April 2, 2026 1:31 am

Good points. In my view, this is why the regulated local utility companies were so easily manipulated, here in NY and elsewhere, to promote EV’s and heat pumps. Revenue. ROI. Improved market share of the energy sources being sold for transport and heating. Sell more kWh through the same wires for better capital utilization. There are limits, of course, but what MBA-level finance thinker wouldn’t agree to go along? Electrify! It’s “Cleaner!” and “Good For The Environment!” And it boosts the bottom line “bigly” but they don’t advertise that part.

That is all for now.

I was on a Condo board asked to install an EV charging station. It sounded simple, but would have required us to upgrade a large chunk of the electricity supply as the standard wiring could not cope. We got a lot of flack for saying no – until we told everyone how much it was going to cost the Condo as there was no way we could charge the installation fee to the people charging their cars.

This was just a small scale issue for a couple of charging points. Multiply this by the kind of numbers the zealots are talking about and the real costs become apparent.

In the UK there are about 32M registered cars. If, in future, this fleet all become EVs the additional load on our National Grid would be enormous. Most of the EV fleet would be put on charge overnight at the owner’s homes because it is cheaper than commercial chargers. If 75% of 32M cars are charging at 7KW it would add an extra load on the grid of 168GW. Currently, the UK has an installed generating capacity of about 60GW and a demand that usually peaks around 45GW. The whole plan to eliminate ICE cars seems like a fantasy to me, or am I missing something?

That works if you are fortunate enough to like the couple of restaurants in walking or biking distance. It also works well as long as the weather cooperates and you are young enough and healthy enough for all that walking.

Some areas are setup so it’s doable, some are not. I live in a small town: no grocery store (has 2 mini marts), no gym, no public pool, tiny library, couple very small restaurant, one coffee shop, no hotel, one gas station, no public transportation, shared police with another small nearby town. Your basic small town in the US. I drive 25 miles to work in an even smaller town then the one I live in.

Next town that’s slightly bigger has 2 whole grocery stores, couple hotels, movie theater, limited public transportation, etc.. In other words it supports the smaller towns in the area but at 20k people it’s not exactly a big city. I have to drive an hour to reach a decent sized city with all that’s needed within it’s boundaries. Even then it’s spread out enough to not be a 15 minute city.

I once walked to the local grocery store, nearest to my house. 1.5 miles took 30 minutes (one way). I was limited to how much I could carry.

The local bus stop is 2 blocks from my house. It runs on 30 minute intervals and does not stop anywhere near the grocery store.

The point is it will take a total destroy and rebuild in my area to achieve anything like a 15 minute city.

15 minute cities are fairy tales.

Amsterdam is a city that evolved that way.

Somewhat off-topic:

The significant difference between different power generation technologies is in the ability to store fuel at the generation site.
This discussion sidesteps all gid issues deliberately.
Maybe someone will see value into writing an article that expands on these points.

WTG and SV have no fuel cost.
Loads of other costs, but those are for a different discussion.
WTG and SV have no capacity to store fuel.
Fuel supply interruptions occur daily and often hourly.
Batteries?
Batteries do not store wind or sunlight.
The real point is batteries are less than zero sum.
More energy is used to charge the batteries than the batteries supply when needed.

Stored hydro?
Same as batteries.
Less than zero sum.
It takes more energy to refill the hydro site than is generated.

Hydroelectric.
Storage capacity is available and a generally cooperative nature will keep the reservoir filled.
However, nature does not always cooperate, so fuel supply interruptions do occur, on seasonal or yearlong intervals.
Political decisions are most prevalent in creating fuel supply chain disruptions.

Hydrogen.
Too funny. Pass.
Hydrocarbons and coal (aka carbon fuels) are free.
The cost is in extracting and transporting to the generation site.
There is a energy debit incurred, but that is a small percentage of the energy in the fuels themselves.
Onsite fuel storage (coal and oil) is common and well understood, coal being the easier.
Natural gas onsite storage is generally not done at the same scale with a preference for pipelining the fuel to the generator.
Yes, supply chain interruptions happen.
Short interruptions are covered by onsite storage.
The frequencies and durations of supply chain interruptions are non-deterministic.
Political decisions are most prevalent in creating fuel supply chain disruptions.

Nuclear.
Uranium, like carbon fuels is free.
The cost is extracting and processing and transportation, much like carbon fuels, although the economies are different.
Nuclear reactors do not consume fuel at rates comparable to carbon fuels and therefore are much less vulnerable to fuel supply chain disruptions.
Nuclear, however, is the most vulnerable of all to political whims and vagaries.

Taken from the fuel storage point of view, nuclear and carbon fuels are the most reliable.

Do you suppose EV owners overcharge their vehicles because of range anxiety? Do they top off their vehicle’s charge every night?

Norway has published accurate, high quality data on the effects of PEVs (Plug-ins). With half the population, Norway consumes more electricity than Sweden,with comparable climate and living standards, due to PEVs and heat pumps, but their hydrocarbon consumption continues to climb higher. They simply have two vehicles, diesel, gasoline, and PEV, where previously they had one. Now, Norway is building AI facilities to consume yet more electricity.
Norway has abundant electrical power from hydroelectric, except that hydroelectric is limited by available impoundment of which Norway has run OUT. Norway requires now more electricity than their dams can produce. Every dry year is a disaster. This is a serious issue for Germany and the Continent who were counting on Norway as backup for electricity. The undersea cables are now turned OFF by Norway when German demands drive electricity prices sky high. It is Norway’s electricity, after all. Further, Norway is developing their Arctic Ocean oil and gas resources asap, along with their North Sea oil and gas.

Those wires that carry electricity are no different than an oil pipeline in that they can only carry so much energy.
The difference is that you can ask a pipeline to carry more than its capacity and it will still pump the maximum.
When you ask the grid to carry more than its maximum, it refuses and stops working all together.
