A
November 2003 report from Embassy Beijing.
The Three Gorges Dam, planned to be
finished in 2009, began to impound water in June 2003 and is producing
electricity, running five turbines from an eventual total of
26. Add-on generation projects will double the power
production of the dam itself. Dam officials downplay
environmental damage, sedimentation risks, and ill effects on the 1.3
million people relocated by the mega-project.
Dam
Built for Flood Control and Power Generation
Mr. Liu
Youmei, Chairman and President of the China Yangtze Three Gorges
Project Development Corporation (CYTGPDC) and Mr. Chen Hongbin, Deputy
Director of International Cooperation Department of CYTGPDC described
the Three Gorges project during a recent visit by United States
Government officials. Construction of the dam has been right
on schedule, according to Mr. Liu. He said the dam has two
purposes: flood control and power generation.
Massive
Dam’s Water Level at Minimum Prior to Flood Season
Construction of the dam has been
an enormous project, and has employed 10,000 people. More than 103
million cubic meters of earth and rock were excavated to build the dam,
and another 28 million cubic meters of concrete will be used to
complete the dam. The dam also contains 463,000 tons of
reinforcing steel rods and an additional 266,000 tons of other metal
works. The dam is 2,309 meters from end to end, and the
elevation is 185 meters above sea level, with a water height of 175
meters above sea level.
Mr. Liu said the dam is equipped
with 23 deep outlets, and that leading up to flood season each June,
the water level of the dam will be drawn down to 140 meters.
The water level will rise during the flood season in July to September
but not above a safe level, he said. Mr. Liu also explained
that through the flood season, the dam would practice sediment sluicing
through the deep outlets. He said this will forestall a large
sediment buildup in the reservoir.
The dam also has an already
functioning series of locks that have the capability to handle 100
million tons of shipping annually, Liu said. He said this
would allow for improved shipping along the Yangtze River.
The dam will also include the world’s largest ship lift, similar to a
freight elevator that can lift a 3,000 ton load 113 meters straight
up.

Impact
on Fish Mitigated, According to Dam Officials
When questioned about the
freshwater dolphin and the dam’s impact on this endangered species, Mr.
Chen responded that the dolphin’s primary habitat is 100 kilometers
downstream of the dam, and that construction and dam operation should
not affect the dolphin’s habitat. Mr. Chen also
ventured information on the Chinese sturgeon that also lives in the
Yangtze River. The migration of the sturgeon was blocked
previously by the construction of the Gezhouba Dam 20 years
earlier. Since that time hundreds of thousands of artificial
spawned fish have been put into the Yangtze every year and new natural
spawning areas have been created downstream from both sites, he
said. Mr. Chen explained that these efforts have been
strengthened since the beginning of construction of the Three Gorges
Dam.
Relocation
Said to Raise Standard of Living
Mr. Chen said that a total of
1.3 million Chinese will be relocated by the end of the
project. Over 750,000 have already been relocated, many to
newly created cities, he said, and the remainder will be relocated
before the completion of the dam in 2009. Relocation costs
are expected to total around $9 billion, Chen said.
Mr.
Liu stressed that the flood control benefits of the dam will help raise
the standard of living of people in the area. He added that
those
who have been relocated are “simple” people that are
“happy with their new homes and what they say is a much improved
living situation.”
Financed
by the Chinese Taxpayer
The estimated cost to build the
dam in 1993 when the project began was $25 billion. This cost
didn’t include power transmission, but did include relocation
costs. It is currently estimated that when completed in 2009
the actual cost will be $22 billion.
The dam was financed almost
entirely with internal Chinese investment. Forty percent of
the project was financed by the central government and sixty percent
was financed through loans to the CYTGPDC. Mr. Liu explained
that the reason for the large percentage of government investment was
due to the fact that flood control and transportation benefits to area
residents couldn’t be recouped by CYTGPDC. The central
government’s funding was achieved by the State Council levying a tax of
0.3-0.7 cent/kilowatt hour since 1992 on all power networks across the
country. The project also received a $1.1 billion credit for
purchasing hydroelectric components.

Electricity
Equivalent to 50 Million Tons of Coal per Year
The Three Gorges Dam when
completed will be the largest single electricity generating facility in
the world, according to Chinese statistics. When completed in 2009 the
dam will have 18.3 gigawatts of installed capacity. A thermal
plant in China would have to burn approximately 50 million tons of coal
a year to produce similar amounts of electricity.
According to Chinese officials,
the dam, when completed in 2009, will have twenty-six 700 megawatt
turbines purchased from GE and Siemens, each producing an average of
4,500 megawatt/hours a year. Eighteen turbines on average
will be running at any given time. Currently, there are five
operating turbines, and the sixth turbine is expected to be online by
the end of the year. The dam has fifteen power circuits,
three of which are direct current that take the electricity to Shanghai
and Guangzhou. The cost of the electricity will be three
cents per kilowatt-hour, according to official statistics.
Mr. Liu said that his company
had just received central government permission to build a power
generating facility at the right (south) bank of the dam with an
additional six hydro turbine generator units totaling 4.2 gigawatts of
installed capacity. The intakes of these units will be
constructed simultaneously with the regular dam project and are already
represented on the main control board.
The
Future – Going Public
Mr.
Liu also explained that the CYTGPDC plans to go public in early
November on the Chinese stock exchange in Shanghai.
(Note:
This occurred on November 17, 2003. End note.) The
Yangtze
Electric Power Company Ltd plans to issue 2.36 billion “A”
(domestic) shares in order to raise about $1.2 billion. This
would be the fourth largest initial public offering (IPO) in mainland
history, according to Liu. The company originally planned to
go
public in September, but regulators forced them to delay, Liu
said.
According to Liu, CYTGPDC plans
to invest the capital from their public offering into building four
power plants downstream from Three Gorges on the banks of the Yangtze
River by 2015. Liu said when this project is completed, these
hydro power plants will generate twice as much electricity as the Three
Gorges Dam. The combined 58,000 megawatts produced by the
dam, the underground power generating facility and the downstream
hydro-plants will make CYTGPDC a larger energy producer than some of
the former state-owned power companies, Liu said.
