Kulekhani- II Hydropower StationThe Kulekhani II Hydropower Station with an installed capacity of 32 MW is cascade power station to Kulekhani- I along with a diversion of Mandu river to the specially built intake for Kulekhani-II. Besides this, when needed some water from Rapti river is also fed to the intake of KL-II by pumping. The operation of this powerhouse is completely dependant on the operation of Kulekhani-I power station.
Since the rehabilitation of the powerhouse in 1994, it is running satisfactorily. But the nine years of running of this powerhouse after the rehabilitation has deteriorated the condition of different part and specially the governing system which is quite old. So this governing system is needed to be replaced by digital governor.
The average (designed) annual generation of the powerhouse is 104.6 GWh. Kulekhani-II Hydropower Station has generated 73.063 GWh of energy in fiscal year 061/62, an increase of 11.41% compared to the last years of generation. The generation from Kulekhani-II contributed 3.02% of the total energy in this INPS.
