    Introduction

    Nepal has 83,000/42,000 MWpotential

    Present peak requirement noted is 1094.63 MW

    Nepal produces only 718.621 MW

    Present energy requirement is 5446.285GWH

    Available energy is 4218.135 GWH

    About 1228.15 GWH energy deficit resultingupto

    12-14 hoursof load shedding each day!!

    Introduction The Medium Hydropower Project of NEA carried out the Feasibility Study of the

    project in 1998.

    Review of Development Plan on the Sunkoshi River and Dudh Koshi River was

    done in 2011.

    The development plan reviewed the project based on the Sapta Koshi High Dam

    Multipurpose Project

    Since the high water elevation of the SaptaKoshi HDMP was fixed at 335.3 amslthe powerhouse of Dudhkoshi needed to be shifted upstream.

    Three major alternatives were proposed.

    Alt I:

    Original dam site+waterway+undewrground powerhouse near Sunkoshi River

    Alt II: Original dam site+surface powerhouse site downstream of Dam body (Toe)

    Alt III:

    Case II+alternative dam site+surface powerhoouse

    Identification and Feasibility Study of Storage

    Project1999 Storage Master Plan Study

    The study was divided into three phases :

    Coarse screening and ranking

    Fine screening and ranking

    Feasibility study

    As the first step, whole nation was

    scanned and 102 storage projects

    were identified.

    Western River Basins : 28

    Central River Basins: : 30Eastern River Basins : 44

    Coarse screening and ranking of 102 projects are carried out based on the Techno-

    environmental aspects and some Threshold Criteria. From Coarse Screening Ten Storage

    Projects were selected for the Fine Screening and Ranking.
