| Summary: | The electric generation design nowadays is one of the key factor to improve the electrical power system efficiency and enhance the usage of clean energy. Geothermal energy is available in every region of the world with its specific depth, where the potential energy depends on the value of temperature, pressure, and mass flow. Low temperature geothermal energy has been one of the best choice because of its flexibility to be implemented anywhere. Low temperature geothermal energy below 149° C uses organic rankine cycle as the main system cycle. One of the most potential region for the implementation of ORC is the Mataloko Village, Ngada District, Nusa Tenggara Timur. Analysis and the system design is done using Ebsilon Professional software. System is able to produce 615.9 kW of output power with 12.15% of efficiency. The research also calculates the electricity energy potential, where the system is able to supply electrical energy to 2,463 houses in Mataloko Village. Total cost per kWh is IDR 209. Profit ratio of 12.79 obtained through selling the electricity to the villages near Mataloko village. Geothermal energy contributes a very small portion of green house gases, and becomes Indonesia’s first choice to substitute the usage of conventional energy. |
