Abstrak/Abstract Recently, the design of renewable energy power plants have been developed worldwide due to its better offering than conventional fossil fuels to meet the green and environmentally-friendly goal. Consideration in the improvement of micro-hydro as one of several types of renewable energy will take part in the decrease of greenhouse gas emissions. In this study investigation of micro-hydro potential at selected locations in coal-fired power plant, Kupang-Indonesia. The design of a potential head and water discharge to be converted into a micro-hydro system. The water discharge that comes from-outlet of a condenser of the steam turbine will be used to generate of micro-hydro powerplant. The water that to be used in MHPP may be one of the major weaknesses due to its characteristic could affect corrosion. Compared to MHPP common systems, that shown inefficient operation in the feasibility overview due to several issues like sediment problem, instability grid, water availability, uneconomic grid, and high cost of construction. The study revealed that the turbine type at water discharge 1.91 m 3 /s and head 10 meter was crossflow. Consideration of the micro-hydro scenario, a minimum required diameter of the penstock pipe to transfer outlet cooling from the steam turbine in place of 1 m. Besides, the configuration turbine design includes the outside diameter of the turbine, and a total of turbine blades are 0.775 m and 1S to generate 112 kW of electricity. Based on the literature study, calculation, and simulations, all the designs proposed could lead to lower emission gas, the power consumption of coal-fired power plants, and cost production
