Electricity Paid But Not In Full

My tenant paid the electricity bill today but not in full; only 1/3 of the outstanding amount. He told hubby that he has not enough money to pay the full amount. We are not going to connect the electric supply then. He finds it weird that the bill amount is so high. Well, there is nothing weird about the electricity bill. If you on 3 units of air-cond 24/7; of course the bill will be very high.
