FACTS High Potential and Kinetic Energy High amount of water BACKGROUND • Currently, Jakarta suffers from annual flood disaster. In 2002, losses due to flood in Jakarta was approximately US$ 980 millions and can increase to US$ 2 billions in 2013. • Jakarta currently deficit 10m3/s of clean water and will increase to 19m3/s by 2020. • Water feeding from Bandung and Bogor is one of the major contributor of flooding and is aggravated by the littering habits of the society and industries along Ciliwung, Cisadane, and Citarum rivers. Power Generation Green Technology Initiatives Water Filtration System OBJECTIVE APPROACH ECONOMIC ANALYSIS AND BENEFITS • Horizontal axis single and double runner Francis turbine is utilized to generate 2.64 and 13.84 MW (required water rate: 10 and 50 m 3 /s ) • Water exiting from the turbine is supplied to water (Micro filtration) treatment system with capacity of 114MGD.
