That's one reason I've put in bigger wires for my own, to keep the Voltage as low as practically possible and continue output for the maximum.
For me it's only a 50mtrs stretch (x2!) but I already gain some 5 Volts, for the power company with kilometers to the next transformer it is standard proper engineering practice.
Any utility that builds such a system one way deserves to fail.
Myself I'm looking at adding an electric heating element to my gas fired water heater and when available use excess solar power.
That part of the world has a very high standard of reliability for their power grid, things like a UPS are al but unknown.
Another big factor is that except for the large trunk lines everything is underground making it far more reliable than the US system of stringing wires to dead trees.
An important measure is to regulate the inverters that sit between the PV panels and the net, they will automatically cut off when the Voltage get's too high and in future they will be centrally controlled.
Domestic smart meters are already being rolled out for years and they also help utilities to monitor and control generation and distribution.
But such systems are already existing on large plants
I was recently shopping around for PV panels and found out Germany requires a controller for domestic use to have an interface for a future monitoring and controlling system.
In Europe the generator and distributor are already separate entities and it's the generator that has to pay x cents per KWh for transport.
I fear I would then end up with two bills, one covering the cost of the energy I want and another to allow the delivery of that energy to the location I desire...
I really don't understand what worries you, over here the lines do belong to a separate company and I can shop around for a supplier of electricity
Exactly the same as with internet or telephone, many providers to choose from, one utility that does the delivery.
I pay one bill that has the KWh's and transmission as separate items, transmission is then paid by the electric supplier/provider to the cable company, it's not my worry at all.
Oh yeah, surprise, there's a third item on that bill, taxes ):
