10 Preliminary study of
downstream release
of water of hydro
power projects
CO-OPERATION WITH IRTCES, CHINA
In India and China, with increase of frequent human
activities, soil loss in the drainage basin becomes a very
serious problem, and a lot of heavily-laden rivers such as
the Yellow River and the Yongding River etc., have been
formed. The characteristics of incoming water and sediment
of these heavily-laden rivers are their annual runoff with
large annual sediment load, and this kind of imbalance
between water flow and sediment load not only leads to
substantial deposition in the river channel, but poses a big
negative impact on the hydraulic-projects on the rivers,
causing serious deposition and reservoir storage loss, which
directly influence the benefits of reservoirs. Therefore, a
large amount of research works on reservoir sedimentation
management have been carried out in china.
The reservoir deposition and storage loss is an important
issue NHPC must face up with, and it is also one of the key
technologies needed to be considered and solved by NHPC.
Whereas, IRTCES has interest in research and training to
solve scientific and engineering problems related to erosion
and sedimentation. IRTCES welcomes future cooperation
and collaboration with organisations all over the world to
promote the international development on erosion and
sedimentation, engineering problems related to erosion and
sedimentation.
An MOU has been signed on the 28, November, 2006
between NHPC and IRTCES for cooperation on various
research areas. A research project on sedimentation
management of reservoirs on heavily-laden sediment rivers
was proposed for further cooperation.
On 20.09.2007 representatives of IRTCES, China visited
NHPC and a meeting was held with NHPC in the Office
Complex, Faridabad, for detailed discussion on
collaborative research on management of sedimentation
in reservoir as per MOU. The methodology, terms &
conditions of the research cooperation are being finalized.
CONSULTANCY SERVICE
NHPC is providing consultancy services in the various fields
of hydro power viz. river basin studies, survey works, design
and engineering, geological studies, geotechnical studies,
hydraulic transients studies, hydrological studies, contract
management, construction management, equipment
planning, underground construction, testing, commissioning,
operation & maintenance etc. to leading organizations of the
Preliminary study of down stream
release of water of hydro power projects
has been taken up as a research
project. Report of preliminary study of
D/S release of water of hydro projects
has been prepared.
Target for the year 2007-08 has
been achieved and detailed
study is being planed for the
year 2008-09.

CO-OPERATION WITH NEIGHBOURING COUNTRIES IN
HYDRO POWER
MANGDECHHU HE PROJECT (672 MW), BHUTAN
NHPC has undertaken the work of preparation of
Detailed Project Report (DPR) for Mangdechhu H. E.
Project at a cost of Rs.7.59 Crores under the Govt. of
India project tied assistance to Bhutan. Subsequent
to signing of the implementation agreement between
Department of Energy (DoE), Ministry of Trade &
Industry, Royal Government of Bhutan (RGoB) and
NHPC on 29.9.2006, NHPC carried out survey &
investigation works at the project and same is nearing
completion. Preparation and submission of DPR to
RGoB is expected to be made by Feb 2008.
VARZOB HYDRO POWER PLANT – I (2X3.67 MW),
TAJIKISTAN
Govt. of India decided to undertake the rehabilitation
of the Varzob – I hydropower station in Tajikistan on
the lines of the feasibility report jointly prepared by
NHPC & BHEL team in Sep’06. A tripartite agreement
for Renovation, Modernization and Uprating of Varzob
Hydro Power Plant – I (2X3.67 MW) has been signed
between Barki Tojik, Tajikistan and NHPC and BHEL
on 7 th December 2006. The MOU proposed to be
signed between MEA, NHPC and BHEL is under
process by MEA.
