South Africa, in fact, has successfully implemented such a pre-paid electricity system. A major power distributor expanded its power network to households. It opted for a pre-paid system, which was very successful with those users who consumed less electricity. While there are many advantages of the pre-paid system, lack of theft to name one, the company, however, failed to initially anticipate numerous logistical challenges.
Still, the success of the pre-paid electricity supply in South Africa holds the promise for Pakistan where the pre-paid approach in combination with smart, temper-proof meters can help address the rampant theft of electricity.
