Khimti 1 Hydropower Project

Sahure,Hawa (Dolakha) Betali (Ramechhap)

Khimti I Hydropower Plant is built with private sector funding as a “BOOT” agreement (Build, Own, Operate, and Transfer) with GON. Construction commenced on 26th June 1996 and Commercial Operation commenced on 11th July 2000. Himal Power Limited operates the plant and sells electricity to Nepal Electricity Authority (NEA). The plant will be transferred to GON at the end of the 50 year license period. At the end of the first Power Purchase Agreement NEA will purchase a 50% share in the Khimti Power Plant for a nominal fee. The Khimti I Hydropower Project site is located in the Janakpur Zone, Central Development Region, some 100 km east of the Kathmandu. Khimti Khola forms the boundary between Ramechhap and Dolakha Districts. Access to the site is by the existing Jiri road 175 kilometres from Kathmandu.

Devighat Hydropower Station

Battar, Nuwakot

Devighat Hydropower Station was founded in 1984 and is currently located at Bidur Municipality in Nuwakot, Nepal. It is considered a cascade project of Trishuli Hydropower. Trishuli river is one of the longest rivers which rises from Himalaya Tibet. Since it is a speedy river, it can generate a large amount of energy. Trishuli Hydropower itself was funded by the Indian Government and generated 21000 KW of electricity. Since the Trishuli river has higher possibilities to generate extra units of electricity, it became the primary source of the river for the Devighat Hydropower station. This project was manipulated by the governments of India and Nepal with the project costing NPR 750 million. The plant was underperforming after the completion of construction. Therefore, in 2011 these two countries started their rehabilitation to achieve efficiency of the plant. Finally, Hydropower generated 14.1 MW of electricity in a year. There is still some underperformance during the dry season because the Trishuli river’s flows get slower during that time. Lower water speeds can not generate electricity as it is capable. There are three units and one of them used to be problematic until 2011 rehabilitation. After all, all three units are in normal condition and performing well. So then, Hydropower capacity increased by 41.76% from 2010 to 2012.

Kulekhani-I, located at Dhorsing, Makwanpur, is the only reservoir type hydropower station in Nepal with installed capacity is 60MW having two units each of capacity 30 MW. This station was designed as a peaking power station but it is often operated to the system requirements for voltage improvement & system stability. The annual designed energy generation capacity is 165GWh as primary energy and 46 GWh as secondary energy. This project was constructed with the financial assistance of World Bank, The Kuwait Fund, OPEC Fund, the UNDP & the Overseas Economic Co-operation Fund (OECF) of Japan & Government of Nepal. The total project cost was US$ 117.843 million and accordingly the project was transferred to NEA with a capital cost of approximately NRs. 1,550 million.

Kulekhani II Hydropower Station

Bhainse, Makawanpur

Kulekhani-II Hydropower Station, located at Nibuwatar, Makwanpur, is a cascade of Kulekhani-I with the installed capacity of 32 MW and annual design generation of 104.6 GWh. It was commissioned in 1986 AD and developed in assistance from OCEF Japan and Government of Nepal at a cost of NRs. 124 million. The Plant has faithfully cascaded the generation of Kulekhani-I while also boosted with water intake from Mandu and Rapti pumping. Every year Mandu intake is cleaned after the wet season to allow the filtered water to the intake pond. A survey was carried out to explore the possibility of the addition of Mandu and Rapti in an extensive scale such that one unit could run while Kulekhani-I is not operated for storage of water.
