During recent years in Pakistan, the demand of electricity has been much more than actual generation. To cater for the difference between electricity generation and consumption, policy makers in the power sector initiated the idea of load shedding. However, during load shedding hours, mostly the consumers start using DC-AC inverters (usually back up by a battery of 120-200 amperes rating), and or electricity generators, to ensure uninterrupted supply of electricity. However, usage of inverters specially causes an increased consumption of electricity during nonload shedding hours. Because, once the electric supply is restored after load shedding, an inverter will start charging its backup battery using usual electric supply, thus causing an extra consumption of electricity. In this paper, we present an analysis of the loss of electricity incurred due to the excess usage of the inverters.
