Pah! Too many amps and not enough volts. What a pansy supply, and an utter waste of copper.
Mains power voltage drop to reduce usage?

Sure. And be fined. And get another smart meter, or no electricity at all.
I just do :-)
LOL. You really do not need more.
What do you need that much electricity for, you run a forge at home? :-D
Because they are friends with the electricity companies, and they asked nicely. Meaning, they both got more money.
Well, no such thing here. This is a modern country :-D
In the UK I can have up to three phases, which would give me 75kW.
According to this page it's 4 grand assuming you have three phases within 20m, which I do, under the pavement outside my house, since all three phases run along there to supply alternate houses with one phase each.

But that page says something very stupid: "Most houses in the UK have a single-phase power supply, which is sufficient to power a 7.4kW EV charger but nothing more. If you want an 11kW charger for an EV, you must upgrade to a 3-phase power supply, which requires modifications to your electrical installation." UTTER BULLSHIT. Why on earth can't I run an 11kW charger off a 100A 240V supply giving me 24kW? The answer - you can if you don't bother with regulations, fit it yourself!
Which would surely negate the point of dropping the voltage in the subtransmission?
It's only illegal if you're caught. You could blow up your neighbour's meter.
An electric shower is 9kW. An electric cooker is 8kW. Does everyone in your country have cold food and cold showers or use gas?
In my case, a supercomputer.
Didn't you recently have a terrible poverty? About a decade ago?
That works, thanks.
The facts are the facts.
3 % voltage reduction results in 1.5 % demand drop. 5 % voltage reduction results in 2.6 % demand drop. Been there, done it, seen it. < no T-shirt though >John T.
If the final substation compensates for the voltage change, obviously you would achieve nothing, just stop and think....
Don't need to stop & think - it works - - afaik it's used by most utilities in North America. It's tested once or twice a year. John T.
It only works because some substations don't compensate. Once they upgrade them all, they've shot themselves in the foot.
Why do you need twice as much as UK residents?
Not to mention hydro!

It's been used for about 50 - 60 years - that foot has healed-up long long ago ! It's not just distribution stations that are supplied from the sub-transmission feeders - commercial, industrial, residential, etc .. much with fixed tap transformers. John T.
Air conditioning consumes a lot less than heating.
Ah, that's your name, I wondered why kilowatts was being written at the end of everything.
Why are they still fixed tap?
Hardly. My meter is inside my house. Even if you don't get caught, they would replace with another smart meter. You gain nothing.
