Kulekhani Hydropower Project: Sailent Features

Kulekhani hydropower project is the only reservoir type hydro power project of Nepal. It was constructed as the five years’ project by the government of Nepal between 1977 and 1982 under the financial assistance of World Bank, The Kuwait Fund, OPEC Fund, the UNDP and the Overseas Economic Cooperation Fund (OECF) of Japan.
The total project cost of the project was US$ 117.843 million and accordingly the project was transferred to NEA with a capital cost approximately NRs. 155 crores. The telemeter system installed for rainfall , water level measurement and indication cost around NRs. 13.74 crores. The cost of road, check dams and inclined tunnel are about 23 crores.

 It’s has the installed capacity of 60 MW having two units each producing 30MW each. Initially it was designed as peaking power station but at present it has been serving as emergency stand by power station also due to the power crisis in the country. It creates the Indra Sarowar reservoir which has an area of 2.2 sq km. Kulekhani dam is an 114m high rockfill dam.  It is named after Kulekhani village development committee in Makwanpur District in the Narayani Zone of southern Nepal.
