The more control boils down to that you can't get one of those surprise 50k bills that the city will insist is not an error, and you must just pay up. Issues like that can take years to resolve.More control? Not sure I get that one. I have both control and convenience with post-paid - that's worth the R60 to me.
Anyway, my average monthly usage, for a family of four, is in excess of 500kwh.
You can also detect issues early, if some broken appliance is sucking power, instead of only finding out once you get the bill.
Prepaid prevents that. In my mind that's the main advantage, it's pretty inconvenient otherwise.
