| Summary: | Beginning with the industrial revolution in the 18th century, it raises the important role of fossil fuels to support the energy needs for people in their life. However, this source of energy is not renewable and have a destruction impact to the environment. So it needs to make diversity of alternative energy that are renewable and eco-friendly. Geothermal energy is a renewable energy that utilizes the thermal energy stored in rocks and fluids in the subsurface. To convert geothermal energy into electrical energy required studies concerning the conversion of heat energy stored in the geothermal fluid into electrical energy in a cycle that work on Geothermal Power Plants. Geothermal Power Plant with Flash Steam Single cycle, is a type of Geothermal Power Plants that is most widely used in Indonesia. Disadvantages of this type of geothermal power plants is there is still large number of stored heat energy contained in the brine, so that the energy output and efficiency of geothermal power plants of this type is cannot reach optimally result. In order to maximize the output and efficiency of geothermal power plants of this type, the insertion of an additional Flashing cycle can be done, so Geothermal with Single Flash Steam cycle can be converted to Geothermal with Double or Triple Flash Steam cycle. Optimization process of energy output and efficiency of geothermal power plants wtih Double and Triple Flash cycle can be done by varying several parameters of the geothermal power plant components such as temperature separator, and the temperature Flasher. Optimization results show that there is an increase in energy output and efficiency about 26.4% for the conversion of geothermal power plant with Single Flash Steam cycle into Double Flash Steam cycle, 41% for the conversion of geothermal power plant with Single Flash cycle into Triple Flash Steam cycle, and 11.5% for the conversion of geothermal power plants with Double Flash Steam cycle into Triple flash Steam cycle at the same reservoir and condenser conditions, which is 220<sup>o</sup>C and 50<sup>o</sup>C. |
