I'm not saying unnoticeable, just the purpose can't be reliably identified.
An estate is supplied across 3 phases.
Several houses share each phase.
There will be a limited number per fuse at the substation, but still that fuse supplies several houses.
Any monitoring isn't going to be at a local substation. And upstream from there the supply is fed via HV to several sub stations.
I don't see where any monitoring of what goes on inside Number 9 is going to take place.
We have our own meters to record our individual usage.
Imagine some poor sod taking a shower (10Kw) at 3am before he walks to work.as milkman or postwoman and gets billed for the EV he hasn't got because then the dish washer kicked in, followed by the drying cycle of the washer.
Chargers don't always take 10 hours, or indeed apply a heavy load to supply, it depends on the state of discharge.
Anyway France will be needing their own leccy before all this, so we'll be buying treadmills so we can power the telly.
We will find a way to befriend our Vlad when we become more dependant on his Nord Stream. The idea of the US supplying our gas needs by tanker seems a bit far fetched to me.
