Estimasi Potensi PLTMH Dengan Metode Regionalisasi Pada Ungauged Catchments Di Kecamatan Suoh

Abstract

. Electricity is the major problem in Suoh sub-district because there is no electricity distributed by National Electricity Company (PLN). Suoh is located in the upstream of Way Semaka and water is available in river tributaries throughout the year which can be utilized for micro hydro power. This research aims to analyse the potency of the rivers including Way Hantatai, Way Sekandak and Way Gunung Lanang. The three rivers are categorised as ungauged catchments. Research method includes analysis of hydrologic similarity berween Way Semaka and Way Besai catchments, application of regionalization method where FDC for Way Semaka was developed from discharge data from Way Besai located close to Way Semaka. Measurement of flow variables in the rivers are used to verify dependable discharge calculated by regionalization method. The potency of electricity power is calculated based on dependable discharge Q50 and head. The result shows that hydrologic similarity exists between Way Semaka and Way Besai catchments. Calculated discharges based on river measurements comparable to dependable discharges between 80%-93% from the FDCs for the three rivers. The maximum electricity power which can be generated are 15.26 KW, 4.12 KW and 2.71 KW for Way Hantatai, Way Sekandak and Way Gunung Lanang respectively
