Three Gorges Dam is the hydroelectric power plant being developed on river Yangtze River in Sandouping, Yichang, Hubei, located in China. This is the largest hydroelectric power plant with the power generation capacity of 22,500 MW when completed. At present the power plant produces 17600MW of power. As per the plans the Three Gorges Dam hydroelectric power plants is to become fully operational by the year 2011.
The wall Three Gorges Dam is 2309 meters long and 101 meters high and it is made up of concrete material. The total steel used for the dam is good enough to raise 63 Eiffel Towers. You will be surprised to know that on the bottom side the wall is 115 meters thick and on top side it is 40 meters thick. The total length of Gorges Dam is 660 kilometers and its average width is 1.12 kilometers.
The generation of power from Three Gorges Dam is a definite advantage since no fuel is required and no pollution will be created. But at the same time its construction has also led to large scale ecological disturbance, displacement of the human beings and loss of numerous important archeological and cultural sites.
