Micro-Hydro Power Plant with Cross Flow Turbine Using Hydrant Pump Flow Pressure.

This study aims to design and implement a micro-hydro power plant (MHPP) using a cross-flow turbine driven by hydrant pump pressure as an alternative energy solution in remote areas. The implementation site is Wonorejo Village, Merauke, which lacks access to the national electricity grid. The system is designed to generate electricity by converting pressurized water flow into mechanical energy and subsequently into electrical energy using a 12-Volt alternator. Test results show that the system is capable of producing an average output power of 480 Watts with a water flow rate of 20 liters/second under 2 bar pressure. The total system efficiency is recorded at 53.5%, including both turbine and alternator conversion efficiency. The system provides electricity for 8 households, enabling basic lighting and battery charging. Compared to the initial condition of zero electrification, the MHPP implementation shows a 100% increase in energy access, and reduces operational lighting costs based on diesel generators by 65%. Additionally, technical training sessions improved local residents' understanding by 80%, as measured by pre- and post-training assessments. This study demonstrates that pump-pressure-based micro-hydro systems are practical, efficient, and sustainable solutions for non-electrified villages, with further potential when integrated into hybrid systems.
