It's a question of scale. Sure, a couple of houses in a street is fine. The available supply can cope. But now scale up to 4, 5, 10 houses then suddenly you are exceeding the capacity of the infrastructure to supply that power. Basic Ohm's Law.
And let's not forget that a huge number of houses are in terraces and so just exactly how do they charge their cars? Or flat-dwellers ?
Not really.
Since the night time draw on the grid is easily within existing infrastructure capacity.
House building now now has to be EV ready.
New EV chargers since 2020 have smart capacity built in by law, to enable charginging to match low grid usage.
I plug mine in at any time, tell to be ready by a set time, say 7:30 and charge to 80%. Then my energy supplier sets an overnight charging plan automatically to match overnight low demand on the grid.
Result I get reduced night rate tariff and I dont overload the grid.
Remember Economy 7, two rates, normal day and reduced night, the idea is not new. But with smart meters the grid loading is far more controllable.
As regards terrace houses, yes that's an issue that is being worked on, it though is not a reason to hold up the rest of the program. Same applies to flats, newer builds needto incorporate multiple charge facilities at the parking bsys.
Also, for the last several years the national electricity wiring grid has been getting renewed and upgraded to all residences as the older cable was already approaching end of service lifespan.
Whole estates in this area of Liverpool have already had the work completed, and others ongoing.
So the defense of the aging grid can't cope is another red herring.
It's very easy.
