how about reading some of the info in the links?
Yea Rag it's still on the agenda
Meantime hoped someone with a better vocabulary than mine might provide a link specifying a time of declining consumer "block" rate, else was around at the time, can confirm any said decline from personal experience
Again hoping not to be accused of excessive repetition, my main concern is whether eg, in the 1940's consumer electricity might ever have been priced at a declining rate based on the individual consumption. But thanks all for your interest
