Funding Agency: Department of Electricity Development ( DoED)
Client: Department of Electricity Development ( DoED)
Date: March 2012 – Feb 2014

Ikhuwa Khola SHP is a run of river project. The available gross head is 320m and the design discharge is 4.0m3/sec giving a total installed capacity of 8.10MW. The headworks consist of approximately 40m long diversion of weir including intake and undersluice. The intake level is proposed at elevation of 1280m a.m.s.l.. The desilting basin has been proposed on the left bank of the Khola. An open canal of length 3.25 km feeds water from desilting basin to the proposed forebay at elevation of 1276m a.m.s.l.. Later, the design flow for power generation is conveyed from forebay to powerhouse by a steel penstock pipe of diameter 1.1 m and 550m length. The penstock alignment follows existing topography at approximately 38O. A surface powerhouse is proposed on the old terrace of river at elevation of 956m a.m.s.l. The project consist 5 number of Pelton turbine. The cross average annual energy is 57,811.20 MWh. The proposed site is not accessible by vehicle pliable roads. The nearest exisiting road head is located in Leguwaghat of hile-Bhojpur road. A new 30km of road shall be constructed to link the project site by road. The nearest substation from the project site is located in Dhankuta. Therfore, a 35 km long 33 KV transmission line is necessary to evacuate generated power into national grid.
