In this paper, the authors present a prepaid energy meter to facilitate energy consumption measurement and to know consumer's maximum demand. The prepaid energy meter concept is shown by Proteus 8 software simulation. The major components are PIC (Programmable Interface Controller) microcontroller, voltage and current transformer, LCD, relay and a load. Electricity has become one of the basic requirements for people and widely used for domestic, industrial and agricultural purposes. The energy billing system used now-a-days are labor and time consuming.
