I can understand why zonal pricing will fail, people will complain when one part of the UK has free electricity and the other part of the UK's prices go up 50%
Well that is just nonsense. no one would see rises of 50% whilst others got free electricity.
That same part of the country that would complain about paying more than others is silent about those same other parts of the country that pay more in SC than them.
Perhaps it would encourage more building of generation infrastructure in these "generation deserts" rather than them being continually rejected via NIMBYism.
lol your transmission network needs a lot of work then.
Who's transmission network are you referring to? Scotland's? Northern England? The South?
