The energy transition toward Net Zero Emission (NZE) 2060 is a national challenge to address a global issue, requiring a comprehensive implementation strategy, especially in the electricity sector, where hydropower plants play a strategic role in achieving the NZE 2060 future target. Optimal utilization of small-scale hydropower will significantly contribute to reducing carbon emissions while increasing access to electricity for communities that still rely on fossil fuels, which have historically dominated Indonesia's power system. Efficient and reliable pico-hydro development requires selecting the optimal combination of turbine and generator to improve system efficiency and reliability. Pelton and crossflow turbines are widely used in small-scale hydropower plants. This study aims to comparatively evaluate the performance of two types of water turbines, namely the Pelton and crossflow, combined with synchronous and asynchronous generators in a 1 kW pico-hydro power generation system. The focus is on analyzing the results, with a concern for efficiency, output, and the system's response to different configurations. The Synchronous-Crossflow configuration achieved the highest power output of 849.9 W at a frequency of 60 Hz. On the other hand, the overall trend indicates that higher frequencies tend to produce greater power output.
