1. World's Largest Water Conservation
Project
China's Three Gorges Project is the largest
water conservation project in the world.
Taking the total amount of
concrete work as one example, the Three Gorges Project totals 26.43 million
cubic meters, 2.5 times the figure for the Gezhouba Barrage project and twice
that of the Itaipu project in Brazil, which is currently the largest water
conservation projects in the world. The main construction targets of the Three
Gorges Project are:
-- Removing 102.59 million cubic meters of stone and
earth and filling with 29.33 million cubic meters of stone and earthwork;
-- Mixing and pouring 27.15 million cubic meters of cement;
--
Erecting 281,000 tons of metal structures;
-- Making and erecting
354,000 tons of reinforcing bars;
-- Building 231,000 square meters of
leak-proof concrete walls;
-- Installing power generators with a
combined capacity of 18.2 million kilowatts.
China now boasts a
contingent of approximately 250,000 workers employed in constructing the water
conservation and hydropower projects. Their experience in building concrete
gravity dams, hydropower plants, and large ship locks have prepared them to
build the Three Gorges Project.
2.
World's Largest Hydropower Plant
Upon completion,
the Three Gorges Project will be the world's biggest hydropower plant in terms
of both total installed capacity and annual average power generation volume.
Twenty-six turbine generator sets, with a per-unit generation capacity
of 700,000 kilowatts, will be installed on the left and right banks of the Three
Gorges Hydropower Station. The overall generation capacity is estimated at 18.2
million kilowatts. The annual power generation is estimated to average 84.68
billion kilowatt hours (KWH), equivalent to one-seventh of China's total in
1992.
The Three Gorges Hydropower Station will be hooked up with thermal
power and hydroelectric grids in central and eastern China, thus improving the
economy and reliability of the electric grids.
Moreover, China has
mapped out state energy strategies by transporting coal resources in northern
China to the southern regions and transmitting electricity generated from the
western parts to eastern localities in a bid to ease the energy shortage in
central and eastern China.
3. Three
Gorges Project to Take 17 Years
The ongoing Three
Gorges Project, which will be the world's largest water conservation facility
when completed, will take 17 years to build.
Construction of the project
consists of three stages.
The preparatory and first-phase projects spans
five years from 1993-1997, whose completion is signaled by the damming of the
Yangtze River on November 8.
The second phase will run from 1998 to
2003. This phase will be completed when the first generating unit in the
left-bank power plant goes on line and the permanent ship lock begins operation.
The third phase is planned for 2004-2009. This final phase includes the
completion of all 26 electricity-producing turbogenerators.
On October
14, 1997, the 63rd Executive meeting of the State Council set November 8 as the
date to block the Yangtze River. That will mark the end of the first phase
construction and the beginning of the second phase.
