Potential Sites Screening for Mini Hydro Power Plant Development in Kapuas Hulu, West Kalimantan: A GIS Approach

Mini Hydro Power Plant (MHPP) is characterized by river discharge and head profile. However, the lack of discharge data and river head information becomes barriers in developing MHPP. In this research, GIS approach is used to assess MHPP potential by analysing spatial data. Head calculation was conducted using neighborhood statistical method while river discharge was approached using SCS-CN equation. Potential sites were determined using potential energy formula. The results showed that study area has 18 potential sites from 100 kW to 5.2 MW. This method is suitable for initial screening only. Further in-depth feasibility study is needed to develop MHPP.
