Does anybody know the rhyme or the reason why some of the kWh on my electric bill are charged at 2.87 RD$, some are charged at 4.09 RD$ and yet still others are charged at 6.09RC$ ? Isn't a kWh a Kwh? If not, I would love to know how to use the 2.87 RD$ ones instead of teh 6.09 RD$ ones. If I have to do laundry at 2:00 in the morning, so be it if it'll save me money!
