Novel technical and economic analysis of water and power co-generation in coastal areas

Somayyeh Sadri, Fereshteh Rahmani


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