As I understood in the courses I took for Power, the use of these were exactly just that: economics. Their essential function is to step up voltage for the transmission losses to be mitigated (step voltage up, current steps down, and since transmission losses are proportional to the magnitude of the current, losses are minimized). Their voltage step down is more efficient (arguably) when not dropping voltage to the low specs. households use, so in turn they are more efficient from the generator to the equipment here (also because of the distance transmitted, but that is a seperate issue). I only remember this from school. Anyone from industry is welcome to take me back to school here! I am sure I need some more of it every so often.
