The utilization of the wasted energy from power plants in power generation becomes a great challenge in recent times. This investigates the feasibility of using Organic Rankine Cycle (ORC) bottoming turbine to recover the energy generated from Al Zour South Power station in Kuwait. Both of qualitative and quantitative methods of data collection were used to collect the required data for this investigation. A block diagram was built for the new proposed model in which the location of the added ORC bottoming turbine is presented. The model includes four modules and each of them has different number of turbines. The amount of power generated per month by applying the new model with using two different extraction line capacities of 10% and 20% in addition to the produced power (1000 Mw) per month for each unit were measured and plotted. As a result, the four modules generated more power as the extraction line capacity increased to 20%. More profit was gained by module four at 10% extraction and it has the lowest rate of return which was 9 years. Based on these results, module 4 is the most suitable to be installed in Al Zour South Power station in Kuwait.
