In an effort to turn the international Lancang-Mekong River into a "golden w
atercourse", China has commenced building a hydro-electric power station on
it,second in size only to the mammoth Three Gorges Power Project.
Situated in the middle reaches of the river within Yunnan Province, Xiaowan
Hydropower Station will have a total installed generating capacity of 4.2 mi
llion kilowatts, bigger than the Ertan Hydropower Station on the Yalong Rive
r in southwest China's Sichuan Province.
The cost of the construction of the power station is estimated at 22.2 billi
on yuan, the ever largest amount to be spent on a project of this kind in Yu
nnan. It is scheduled to be completed in 2012.
The Lancang-Mekong River, known as the "Oriental Danube," is the only intern
ational river running through six Asian countries. It originates in the Qing
hai-Tibet Plateau and runs for 4,880 km. through Laos, Thailand, Myanmar, Ca
mbodia and Vietnam.
Xiaowan Power Station is one of the key projects to be built during China's
Tenth Five-Year Plan period (2001-2005) and an important part of China's str
ategy for transmitting electricity from resources-rich western areas to powe
r-short Shanghai Municipality, Guangdong, Jiangsu and other eastern province
s. While giving priority to power generation, the power station will perform
other functions such as flood control, irrigation, sand retention and navig
ation.
Pan Jiazheng, a Chinese hydro-electric expert, said, "Establishment of the p
ower station will benefit all countries along the river."
According to a memorandum signed between China and Thailand, power stations
on the Lancang-Mekong river will start providing electricity to Thailand fro
m 2013.
The Mekong River basin has 13.5 million hectares of cultivated land, which i
s prone to flooding in summer and lacks irrigation in winter.
When the Xiaowan Power Station starts operating, there will a reservoir with
water storage of 15 billion cubic meters. This will reduce the amount of wa
ter flowing downward by 17 percent during flood seasons and increase the flo
w by 40 percent in dry seasons, says He Daming, director of the Asian Intern
ational River Center affiliated to Yunnan University.
Construction of a 292-meter-high dam will block 35 percent of the silt now r
eleased into the lower reaches of the river. This will be advantageous to ag
ricultural and fishery development in the northern part of Thailand and the
Vientiane Plain and facilitates navigation on the Mekong River.
China and Laos organized trial shipping runs on the river in 1990. The river
was opened up for commercial navigation simultaneously in China, Laos, Myan
mar and Thailand last June.
More than 38,000 people in the dam area, all of whom live in China, are to b
e relocated.
Reduction of silt in the river will be conducive to fish production in the l
ower reaches. A 300,000-square-kilometer reserve will be set up to protect m
acaque and other rare animals in the region.
"The experience of building power stations on international rivers has prove
d that they exert no negative influences on the environment," He Daming says
.
Xiaowan Hydropower Station is the second of the eight hydro-electric power s
tations to be built on the Lancang-Mekong River and the largest water conser
vancy project in Yunnan in the past 50 years.
