3 gorge hydroelectric station, namely the Yangtse River 3 gorge project of key water control project, call 3 gorge the project again. The gorge of long Jiangxi hill of churchyard of city of Yichang of Chinese Hubei province paragraph with downstream Ge Zhou dam hydroelectric station makes stair power station. 3 gorge hydroelectric station is the hydroelectric station with the at present largest scale on the world, also be the project project with the largest construction of Chinese throughout history. But to 2020, the history will be adapted, the whole world is the greatest hydroelectric station this special honour is 3 gorge hydroelectric station no longer, be located in Congo river however flower add hydroelectric station. Flower add hydroelectric station, it is the establishment of important irrigation works that is located in Congo river to go up, capacity of aircraft of design general assembly 44, 000 million are made of baked clay. Project is divided in all period, among them the 3rd period the project predicts to built 2020, world the biggest hydroelectric station will be become after building entirely. Flower add hydroelectric station to be located in Congo (gold) next Congo save churchyard, in building the 25 kilometre reach on Congo river, water level fall amounts to 100 meters. Capacity of aircraft of power station general assembly 44, 000 million are made of baked clay, will undertake developing in installment. Total installed capacity will exceed to amount to the 3 gorge project of 22.5 million kilowatt after building entirely, become one of the biggest hydroelectric station on the world. Among them, flower add hydroelectric station one, 2 period project in all 14 generation set, total installed capacity is close 1800 million are made of baked clay, 3 period the project will begin to build 2015, predict to built 2020 generate electricity. Flower add 3 period project, also say British add first phase project, belong to British the main component that imposes a plan, british impose a plan total investment 80 billion dollar, by 11 dam and composition of project of 6 water and electricity. This project generates electricity dimensions design covers with tiles for 4800 million, the project plans to built 2020. After this project builds, 2500 million tile will carry south Africa directly, 2300 million tile is used at satisfying Congo (gold) domestic company (add red to add company of province mining industry especially) the demand that use phone. Congo river river is full-length 4320 kilometre (with the source is on the west on source) , dry affluent drainage area kilometre of 3.7 million square. Drainage area and discharge all are next to the Amazon, house world the 2nd. It is the chute with world water the largest amount. Flower add hydroelectric station to build the key position of main water and electricity in this one reach namely. Flower the building that adds hydroelectric station put into production, will make electric power productivity of Africa raises at least one times, can alleviate effectively the problem that African the sources of energy is in short supply, attract an enterprise to come here to invest. Still can drive Africa other industry grows, predict to still can execute electric power to export other further country. The environmental issue that its bring adjusts to silvan natural resources and climate for example destroy, flood downstream area to wait, these issues cannot be ignored. And build giant the emigrant problem of hydroelectric station also gets attention fully, a lot of media report denounce is gigantic endowment build hydroelectric station to also can bring a lot of corrupt issues.
