In this paper, the authors are proposed to reduce the electrical power demand in domestic and industrial sectors. Through this technique the power supply is controlled and supplied is achieved. The electric supply is turned off when it crosses above the threshold power level; this switching is done with the help of relays. The power measurement is done with the help of power measuring circuit which is connected across the supply and to the microcontroller in which the programs are embedded. The ZigBee is employed to control and communicate with the power outlets.
