Cross-subsidies have already been prohibited in Rhineland-Palatinate municipal economic law during my time with the Juso youth organization. That's so long ago that surely the other federal states have caught up by now. and for this purpose to reduce the chimney density. However, the system-related interlocking of the incompetences of municipal utilities and councils is always gladly seen by those involved.
haha, that was good. If the municipal utilities operate public transport at the same time, do I need to say more? Then there is also something like profit transfer in the GmbHs, no, none of this is cross-subsidization. *laugh*
You also don't reduce the chimney density; chimneys/stoves are not allowed to be banned, the Higher Administrative Court already put a stop to that decades ago.
Number 4.10 alone would annoy me a lot, where it is precisely prescribed how I have to build what. I have to ask the municipal utilities if I may connect a towel radiator and then also the underfloor heating, it can't get any more crazy than that.
But as long as we don't know anything about the monetary side, everything is still very much fishing in murky waters.
The fact is, geothermal energy does not pay off in modern new buildings, with mandatory photovoltaics even less so...
