Reservoir Enlargement and Energy Production Comparison of Dry, Normal and Wet Year at Nam Sana1 Hydro Power Plant Kasy District, Vientiane Province

Abstract

Enlargement of reservoir is one of the technical aspects to increase the storage volume in order to store water and produce more energy. Consequently, the study is to identify the dimension of the new reservoir volume at the Nam Sana1 weir site and also calculate the energy production, the results are found that dimension of the new reservoir the maximum water volume in the reservoir is 264,870 m3, average soil excavate depth from 643.00 to 638.00 masl is 5 m, and soil excavate volume is 332,156 m3, which is the level between the water level at the 642.00 to 638.00 masl
