The capital and operating cost of generation using different types of fuels are given in the table below. Find an optimum generation mix for the given load duration curve given on the attached sheet with peak load of 3000 MW. Consider an annual carrying charge of 12% for the capital cost and 15% planning margin. Specify number of generators of each type.
