Load estimation is the most fundamental and most important stage in network development in future , and its calculation for future plans requires proper accuracy. Its validity coefficiency should be studied , so that the amount of investment in projects does not result in losses due to ( narrow mindedness ) or overgenerosity in designing of power industry installation . Khuzestan is among the regions which has the highest consumption of electricity in the country , and the demand increases annually due to industrial development , population growth , urban extention and increasing use of electrical equipments.

In 1380(2001) the estimation of the maximum load and energy in the functional area of KWPA was reevaluated , and given the growth rate of consumption components and calculation of proper simultaneity coefficient among them , this amount as estimated for next 8 years.

Table 17 offers the estimation results of maximum load needed by Khuzestan from 1365 to 1388 ( 1986 - 2009 ). It is notable that because of the fluctuation of economic structure and execution of power consumption management mechanisms that leads to adjustment and improvement in future processes of power consumption , the above-said calculation will be examined regularly. Furthermore , with respect to the growth rate of the load , it is expected that the required load of Khuzestan in long-term programs reaches to 10100 MW by 1400(20021).
