There has been no problems with EV charging loads, and we have a lot of them. 5kWh consumption per car per day on average is not a huge deal, especially if you consider refineres use half that just in electricity to make the fuel it replaces.
So many problems with that way of thinking.
a) average is meaningless, peak consumption is the only relevant number when it comes to EV. Well, electricity, period.
b) there have been no problems so far because there is currently plenty of excess production capacity to turn on
c) plenty of consumers with load shedding in their supply contract, so extraordinary peaks are manageable until that is regularly used up.
d) ask your local utility what that currently means for peak grid loading. And they will usually tell you that parts of towns with lots of EV cars (and grid connected roof PV) are pretty much on the edge*.
e) lots of small consumers add up. Here going all EV would mean an extra 15GW load, on average, with 60GW being the current average total..25% more, not too bad. But cars are not grid connected 24/7. If its 12 hours on average you are talking 30GW (+50%), if its 8 you are looking at 45GW (+75%) extra load.
f) that's the average day. There are plenty of non average days. You know, when lines form at the gas station..... holiday weekends mostly. As I said: all hooked to single phase AC only is way above what we can supply.
e) utilities wouldn't sink billions over billions in smart grid modernisation if that wasn't a big concern.
I am not saying EV is bad, or not where we will and should ultimately end up with, it is just not remotely as simple as people think. Power doesn't come out of an outlet, it has to be made and transported, just in time, with millisecond precision, in exactly the right amount. Just look at the infrastructure a DSO has to but in place to support a newly opened aluminium plant. That's just a city block or so worth of EV charging.
*i do talk with people from major DSO/TNOs just about every day, as critical infrastructure/substation automation is one of our verticals, they all want to be able to turn your charging off or bill surcharges at peak times. I am literally getting paid to make you pay.
This Singature is a safe space......
