Figure 6. Dependeble Flow Figure 6. Flow duration curve for each operation rule alternative Figure 7. Water level storage chart for each operation rule alternative Scheme 2 has advantage that it fits the electricity absorption rules by the State Electricity Company and at dry season is still able to provide electricity at peak hours. Additionally, secure against potential flood in puddles, as well as the primary energy is fulfilled. While the drawbacks in the form of operating at low elevation reservoirs is limited. This scheme has the flexibility to be converted into one scheme in wet years and became scheme 3 when targeted to generate a larger primary energy. From the simulation shows that: - High water level during the rainy season can be arranged with a longer duration to be able to meet the flow of water in the dry season. - Lowest lake water level and lake lowest discharge setted up from October into November. - With longer dependable discharge duration will be able to increase energy. - The elevation of annual highest Lake water level average is at 512.01 m and lowest at 510.24 m. 406
