Innovating engineering technology
Strategy of "integrated industry chain"
The Nam Ou River cascade hydropower
stations project is developed by Overseas
Investment Co., Ltd. under PowerChina,
and other key companies undertake
the design, construction, supervision,
manufacturing and operation of the project.
In this project, all participating companies
fully leverage their advantages in
technology, management and construction,
and generate an innovative model of
"integrated industry chain" with the
characteristics of Nam Ou River. The core
of the model is the "Quadriad integration"
of investment & development, design &
supervision, construction, and operation
& maintenance, which aims to connect
the entire industry chain from investment,
financing, construction management to
asset operation, and realize the control of
the project's full life cycle as well as the
entire industry chain.
The unique advantages of the "integrated
industry chain" model of the Nam Ou
River project make the construction and
development process controllable and help
the overall improvement of operational
performance. Thanks to the model, the
Nam Ou River project has achieved a
solid progress in localized operations,
ecological and environmental protection,
project resettlement, and charity and public
welfare, realizing significant social benefits.
Meanwhile, the model has expanded
the international market development
channel. All participating parties of the
project turn their respective advantages
into integrated advantages, improving
value creation, innovation and international
competitiveness.
In the "2016 Energy Annual Conference and
the 2nd Energy Development and Innovation
Forum" organized by China Reform
Daily, PowerChina's overseas investment
"integrated industry chain" management
model won the "2016 Overseas Energy
Project Innovation Award".

In November 2017, river closure was simultaneously completed for Nam Ou River level-1 and level-7 Hydropower
Stations. Deputy Prime Minister of Laos Zonse Siphandone attended the river closure ceremony and struck the brass
gong for blessings.

"In 2016, determined to overcome whatever difficulty it may encounter, PowerChina
started the Nam Ou River cascade hydropower development project in Laos. The
Nam Ou River project involves unprecedented large scale, huge construction
span, severe technological difficulties, tough resettlement project and complicated
external environment. However, with the innovative strategy of "integrated industry
chain", PowerChina fully leverages the professional capabilities of the investment
subject in project financing, capital operation and construction management, and
demonstrates the strengths of the leading enterprise of China's hydropower industry
that is undoubtedly the No.1 brand in the international hydropower construction!"

Development and Innovation Forum
The "seven-level reservoir" highlights
the benefits of the whole basin, plays
the connection and adjustment role of
the basin cascade hydropower stations,
and generates significant comprehensive
economic and social benefits of the
cascade hydropower stations. With
minimum people relocation, minimum
flooding loss of arable land and
woodland, and minimum environmental
impact, the development solution
obtains maximum comprehensive
benefits and achieves sustainable
development. The completed hydropower
stations have played a positive role in
adjusting seasonal drought and flood
within the basin, improving the flood
control capacity of the lower reaches,
improving river shipping, reducing water
loss and soil erosion, and protecting
ecological balance, and have gained
recognition from the Laotian government
and international environmental
organizations.

O Design plan of a "seven-level reservoir"
The Nam Ou River project innovatively
adopts the design plan of a "seven-
level reservoir". The plan involves small
amount of earthwork and can minimize
environmental impact caused by the
project's construction. Furthermore,
the operation and adjustment mode of
"seven-level connectivity" can maintain
the ecological system balance of the river
basin to the largest extent.
The Nam Ou River "seven-level reservoir"
is developed in two phases, with a total
installed capacity of 1.272 million kilowatts.
After completion, it will be an important
clean energy base for Northern Laos,
providing reliable power supply for the
construction of the China-Laos Railway and
Laos' "Southeast Asia Battery". The first
phase of the Nam Ou River hydropower
stations has been put into operation; total
installed capacity of the second phase
hydropower stations is 732,000 kilowatts,
and the construction of the main project
started in April 2016, which is expected to
start power generation in 2019.

O Computer network management
After completing the construction of the
first hydropower investment BOT project
in Laos, Nam Ngum 5 Hydropower
Station, No. 10 Bureau of SINOHYDRO
under PowerChina has taken up the
responsibility of the hydropower station's
operation and maintenance. From
construction management to operation
and maintenance management, lackage
of talent has become the biggest issue.
However, PowerChina employees
are bold in practice and innovation.
Informatization management has been
introduced, realizing computer network
management covering decision makers
and production operations of various
departments and workshops (teams and
groups) of the grassroots hydropower
station, and creating good internal and
external environment for the hydropower
station's safe and economic operation.
Since the hydropower station was put
into operation, equipment has been in
a sound condition, and operation and
maintenance has been in order. There
has been stable and safe operation for
over 1,200 days, and electricity generated
accumulatively is more than 200 million
kilowatt-hours, bringing tangible benefits
for the Laotian government and people.
