ENERGY, EXERGY AND THERMOECONOMIC ANALYSIS OF LAHENDONG BINARY - CYCLE GEOTHERMAL POWER PLANT AT NORTH SULAWESI INDONESIA
Indonesia is blessed with relatively abundant potential renewable energy, geothermal potential is about 27,000 MW, it is equal to 40 ％ of the world potential. However the utilization of geothermal energy in Indonesia is still very low compare to its huge potential. In 2010, total installed capacity of geothermal power plant was only 1200 MW or 4％ of total installed capacity of geothermal energy in Indonesia. In order to minimize the global warming as a result of the increase of greenhouse gases (GHGs) emission, Indonesia have now to look into the use of clean energy such as geothermal energy sources.This paper was written to evaluate an energy, exergy and thermoeconomic analysis of a binary geothermal power plant. As a case of this study, data of geothermal field at Lahendong, North Sulawesi Indonesia was used .The results of this analysis shows that the cost formation process throughout a plant from the total capital investment, revenue requirement, main product unit cost ( $/kWh) and cost rate associated with the product of the geothermal power plant (S/h) can be determined.
