Potential of the Molawin creek for micro hydro power generation: An assessment

Abstract

© 2019 Elsevier Ltd The hydropower potential of the Molawin creek in Laguna, Philippines was evaluated. The river flows along the Molawin-Dampalit subwatershed and was declared a BioPark to protect and develop the flora and fauna. The abundant BioPark resource could showcase beneficial products and technologies for communities in mountainous areas. The study aims to propose methods to assess hydropower potential that can be applied to rivers and small water resources. Limited studies were done on the watershed. Previous hydropower studies were based on elevation alone. Hydrographic survey and analysis for gauged and ungauged locations were done. The Hydrologic Frequency Analysis (HFA), rational equation and Flow Duration Curve (FDC) were used to analyze the actual and simulated streamflow data. The HFA Log Pearson III distribution best fits both actual and simulated data. The rational equation overestimated the streamflow. The Plant Capacity Factor (PCF) was obtained using the FDC. The FDC generated from actual streamflow was used for turbine ratings because the simulated data gave unrealistic PCF results. It is recommended to have two Kaplan turbines, one operational during low flow months and two on months of high flow. The PCF at turbine rating of 2.3–7.5 kW and 1.9–5.5 kW were 49.9% and 51.8%, respectively.
