Energy Potential of Macopa Irrigation using Pico-Hydro Power Plant Design Utilizing Under-Shot Type Waterwheel

This study aims to analyze the potential of the water flow in Macopa, San Francisco, Surigao del Norte irrigation and utilize the energy to construct a pico-hydro power plant. The study was carried out using a microcontroller to measure and record the water flow’s speed and velocity and calculate the irrigation flow’s hydraulic power. The average water speed of the irrigation based on the design of a head size 2. 7034m is 7.283 m/s and the average volume of water in a day is 1,391.36 m3/hr. It can be shown in the graph that water volume is consistent over the whole day. The average power delivered by the irrigation is 4. 35W from the average of 62 rpm of the under-shot type water wheel with respect to the design generator and specification. It was also evident on the graph that the power has consistent over the whole period of the day. The results show that it has potential renewable energy, which is the irrigation flow can be achieved as a water resource for the construction of a mini hydroelectric power plant to provide electricity such as street lighting all over the community.
