One of the most influential improvements in geothermal industries has been the application of double flash power plants which can produce more power in comparison with single flash one. Although it is more expensive; however it is a reasonable option as the additional output power can justify the prices. The aim of this study is to represent a methodology in which a double flash power plant is thermodynamically designed and optimized in order to maximize the output power; and make a comparison with other possible type of geothermal power plant (single flash) for Meshkin Shahr region. Besides it represents the study of exergy and energy analysis for plant components through the optimization process; which can guide one to assess the operating status of plant components. It has been shown that flash vessels are the greatest exergy dissipaters and double flash power plant can be more efficient than single flash for this region.
