Upper Chhandi Khola Small Hydropower Project(4 MW)
Upper Chhandi Khola Small Hydropower Project (UCKSHP) is a Run-of-River type hydroelectricity generation scheme with an installed capacity of 4.0 MW. The project is aimed at generation of 22.05 GWh average annual energy before 5% outage using design discharge of 0.67m3/s at Q40 off Chhandi Khola (a tributary of Dordi River) and net head of 712.15 m. The proposed project site is located in Bansar and Phaleni VDCs of Lamjung District in Western Development Region of Nepal within the geographical boundaries 280 16' 05" N to 280 17' 46" N latitude and 840 28' 38" to 840 29' 57" E longitude. The proposed headworks and powerhouse of the proposed Upper Chhandi Khola SHP is located on the right bank of Chhandi Khola at around 3 Km upstream (river stretch length) and at around 100 m upstream of the headworks site of existing Chhandi Khola Hydropower Project on the right bank of Chhandi Khola, respectively in Bansar VDC. The catchment area at intake of the Upper Chhandi Khola hydropower project is 13.51Km2.
