Bhote Koshi-5 Hydroelectric project is located approximately 90 km northeast from Kathmandu, the nation’s capital. It is conveniently located and has access to blacktop road which goes to China border via Barhabise from Arniko Raj-marga highway.
It is located in Sindhupalchowk District of Bagmati zone in the Central Development Region of Nepal. The Bhote Koshi is a tributary of Sunkoshi river a major river of Sapta Koshi river system. The headwork of the project will be located at Maneswara and Gatte Village Development Committee (VDC) and the powerhouse will be located at Ramche and Tekanpur VDC of Sindhuplachowk district.
The access road from Barhabise to Intake site is 5km (approximately). The project road consists of 4 km. from powerhouse site to intake. The intake is near the Maneswara village and the powerhouse is located at Topka village. The general layout of the project, as per desk study Report, is presented in Project Layout Map (Figure 1).
The Bhote Koshi-5 Hydroelectric Project is a simple run-of-river scheme. The general layout of the project consists of a simple diversion weir, a side intake, a surface desander, a small reservoir, 6.2km long headrace tunnel, a surge tank, about 600m long penstock, a surface powerhouse and a 50m long tailrace tunnel. The gross head and design discharge of the project is 150m and 36.5m3/s respectively. With an installed capacity of 60MW, the project will generate about 329.34GWh energy per year including 178.42GWh of firm energy. The power will be evacuated by a 2 km long 132kv single circuit transmission line to the nearest substation at Sunkoshi sub-station.
Foreign Private Investment in Hydropower sector:
There are currently three hydro projects being promoted in Nepal involving foreign investment. A U.S.-Nepal joint venture has completed construction of the 36 MW Bhote Koshi project, a mixed public/private 60 MW Khimti developed on the Khimti River and one export oriented project in the offing 750 MW project on the West Seti River.
Bhote Koshi
The Bhote Koshi Power Company was established in June 1996 to develop and operate the 36 MW Bhote Koshi hydropower plant. The major shareholders are Himal International Power Company, Panda and Harza, the latter two are American companies. The NEA purchases all energy generated by the Bhote Koshi project through a PPA.
Khimti I
The 60 MW Khimti I project was developed by Himal Power Ltd. (HPL), a Nepalese company with major shareholders comprising BPC, Statkraft S.F. (state company of Norway), ABB Kraft AS, and Kvaerner Energy AS (Norwegian Companies). A Power Purchase Agreement (PPA) between HPC and Nepal Electricity Authority (NEA) was signed in January 1996. and currently NEA purchases all the energy from this power station.
West Seti
The Snowy Mountain Engineering Company (SMEC) of Australia is trying to developing the West Seti project, a 750 MW hydro scheme located in the Far Western Development Region. An agreement has been signed with the Nepalese government to allow the export of electricity and negotiations for power purchase agreements are ongoing with Indian utilities.
