Preliminary Study of Micro-hydro Power Plant (MHPP) in The Rural Area

Pakenjeng village is one of the villages in the subdistrict Pamulihan, Garut. Garut regency has the potential of natural resources is quite large and varied, namely water resources, energy, and mineral resources. Energy resources available in the form of the potential of renewable energy such as geothermal energy (geothermal), micro-hydro, solar, wave, and wind. Judging from potential micro hydro, Pakenjeng village crossed by two rivers with a flow of water large enough, the river Cikondang and Cibatarua. Currently, both the river Cikondang and river Cibatarua been used for hydroelectric power plant, with a capacity> 100 kW (scale mini-hydro), ie power plants Kombongan (river Cikondang) with a capacity of 165 kW and a power plant Panyairan (river Cibatarua) with capacity of 3 x 200 kW. The result of the potential study (pre-feasibility study) showed that Sungai Cibatarua have the quality and quantity of water that is eligible to be a source of hydroelectric energy for water discharge stable and constant reaches 5100 liters / sec. Cibatarua River has a waterfall that has a head that is high enough that Niagara Panyairan with head up to 63 meters. Hydraulic power that can be generated to reach 3248 kW and a power that can be awakened by the turbine reaches 2404 kW. Potential analysis (prefeasibility study) of the mechanical and electrical indicates that the turbines are suitable for the MHP in the River Cibatarua namely Cross Flow Turbine Type TC 15 BO 650 with power up to 1 MW.
