The LW radio teleswitching technology is a hugely underused resource. I was initially under the impression it only served as a time reference to keep white meter clocks in sync, but there are actually tariffs which use it to turn on and off storage heating according to weather and generating forecasts.
This proven 'one to many' communication and control should provide valuable flexibility in an environment where electricity markets frequently pay out more for 'units not used' than 'units generated' and when technologies such as electrification of transport and heat offer more opportunities to shed non-time-critical load at times of peak demand (and price)
It seems a great shame that the technology was and is so underused. It's something that could be rolled out immediately with, eg electric vehicle charging, because it's not dependent on smart meter technology whose roll-out, functionality and reliability remain questionable.
