Load management(LM) reduces the electric power consumption by altering the shape of the overall system demand versus time curve, in the aim of achieving better balance between the customers cycle demand and the utilities current and planned generation capacity, transmission and distribution (T&D) resources. LM programs use a variety of different means to manage electricity demand either by direct load control or indirect load control through variable tariffs. This study has found that from the utility point of view the capacity saving at the horizon year is about 130 MW and the overall energy saving for the whole planning horizon is about 9.7 TWh if the LM is carried out in industrial sector of the main interconnected power system of Oman. The CO2 equivalent saving is about 5.4 million tons for the whole planning horizon. The total avoided cost saving is around M$ 161.
