Today all forms of human needed depends on the availability of energy in the world. This causes the energy must be maintained availability. One of the most indispensable human energy today is electrical energy. One solution that can be used to prevent the occurrence of electricity crisis, especially in Indonesia is to explore the source of renewable energy, namely geothermal energy (geothermal energy). Indonesia is currently the third largest geothermal producer in the world, with seven geothermal areas spread across Java, North Sumatra and North Sulawesi producing around 1,439 MW. One of them is the Wayang Windu power plant in West Java. Currently PLTP Wayang Windu uses a single flash cycle to generate electrical energy. The steam coming out of the geothermal well in Wayang Windu still has considerable water content. The addition of steam from the flash separator will affect the existing Wayang Windu PLTP system. Therefore, thermodynamic calculations are needed to find the design conditions for each component in the Wayang Windu PLTP and check the condition of each component after the addition of steam from the flash separator. Thermodynamic calculations will use Microsoft Macro Excel VBA software. The results obtained are double flash modeling with one turbine producing 3,5 MW more power than double flash modeling that produces 1,2 MW.
