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.

Challenges
Load shedding has Negative impact on Industries, commerce,employment and national economy, social disorder and resentment
Declining overall rate of countrys development
Reduced export and increasing import
IPPs discouraged for investing in HEPs
NEAs financial health declining
Energy surpluses in wet season and deficit in dry season
(Q40 design). Management of surplus energy.
Favorable PPA for all investors
Nepal Governments Ten year 10,000 MW and 20 Year 25 000 MWPlan implementation.

Way forwardOpportunities
Nepal has growing and guaranteed energy market. Energy market is flexible and adaptive to the market demand with
export potential
Investor friendly plan, policy and PPA. NEA open to collaborate withinvestors/ partners/Donors and Developers
Heading towards deregulated energy market and allow market toaddress the problems of developing energy sector.
Government committed to fulfill its commitments and obligationstowards IPPs and investors for Transmission lines, substations etc./ FixTariff for storage projects
Create autonomous and profitable NEA in true sense.
Flexible or Fix tariff on cost plus basis and PPA on competitive basis. Better NEA means better confidence to IPPs.
Assured returns on investment
Cooperation between all stakeholders
