Pakistan is suffering a lot from energy crisis; unscheduled load shedding has hurt a lot. Many bushiness have gone away from Pakistan because of lack of power supply. Especially in Punjab, electricity crisis is the worst. In Karachi from the last 20 months KESC has at least relieved common people by doing 80% load shedding on time.
There are many reasons for electricity crisis in the city which includes mismanagement, dishonest, political appointments in power companies, corruption etc. The other big reason of crisis is Kunda (illegal electricity connections), non-payment of bills at due date.
If government introduce prepaid electricity meters then this will help in a big way and one has to buy electricity card (like mobile cards) and then he/she can use the electricity.
