Analysis of the current status of power plants and finding solutions to increase their efficiency is essential because of longtermrising fuel prices, environmental concerns and an ever-increasing demand for energy in the world. A basic approachto maintaining the existing units is to increase energy efficiency by using these units in the cogeneration cycle, based ontechnical and economic considerations. In this paper, the technical and economic evaluation of a gas power plant in centralIran is used with reference to a combined electricity and freshwater generation system on Iran’s southern shores. Resultsshow that the two gas turbines, a heat recovery boiler, condensing steam turbine and reverse osmosis unit at Chabahar is themost attractive scenario, because it has the highest net present value, internal rate of return, the quickest payback period andthe lowest price in the studied scenarios.
