The project consist of preparation of Due Diligence Study of the project for financing with the consortium of banks which is lead by Machhapuchchhre Bank.
The proposed Super Sabha Khola A Hydropower Project will utilize the flow available in Sabha Khola which is the tributary of the Arun River. The Arun River is later evacuated into one of the main rivers, the Koshi River in Khuwalung. As per the Feasibility Study Report and Power Purchase Agreement (PPA), the design discharge of the project is 4.25 m3/s and 4.47 m3/s at the probability of exceedance of 41.9 % and 42.68%. The diversion weir is located just downstream from the confluence between the Giddle Khola and Sabha Khola at Wajok village. The headworks arrangement is located on the left bank of Sabha Khola, where design flow is diverted from the intake-gravel trap to the settling basin via approach canal. As per the Feasibility Study Drawings, the flow then passes through a 2200 m long 1.6 m diameter headrace pipe up to the surge tank and then via a 517 m long penstock pipe of 1.6 m diameter. The powerhouse is located at the river plain land below a rocky cliff on the left bank of Sabha Khola, between Apun and Sikden villages. The powerhouse consists of 2 units of horizontal axis Pelton turbines to generate 9.412 MW of power. As per FSR, the generated energy is proposed to evacuate at Tumlingtar Sub-station, Sankhuwasabha via a 20 km long 33 kV single circuit Transmission Line.
