ha ha. nice try yourself. All you have demonstrated to far is that my maths is sketchy and you are a cunning linguist.Nice try, but "huge revenue generation" is an entirely compatible statement alongside "no justification". Something can be expensive and not sold in sufficient quantity to make huge profits.
My original point was I don't understand the economics of changepoint operation well enough to be able to judge your statement that "clearly there is no justification" for 50p/kwh.
Do you? and if so can you explain it to me ( using small words ideally) or is it that some companies charge less and you just don't want to pay that much? a point on which I am more than happy to agree.
