Gezhouba Dam

Gezhouba Dam

The Gezhouba Dam or Gezhouba Water Control Project on the Yangtze River is located in the western suburbs of Yichang City in central China's Hubei province. The dam sits a few kilometers upstream from downtown Yichang, just downstream of the fall of the Huangbo River into the Yangtze. Construction started on December 30, 1970 and ended on December 10, 1988. The dam has a total installed electrical capacity of 3,115 MW.

After rushing out of Nanjin Pass, the Yangtze River slows down and widens from 300 metres (980 ft) to about 2,200 metres (7,200 ft) at the dam site. Two small islands, Gezhouba and Xiba, divided the river into three channels. There the Gezhouba Project was built.

The facility boasts a generating capacity of 3.11 GW along with three ship locks, two power stations that generate 14,100 GWh of electricity annually, the 27 gates of the spillway, and the no flowing Dam on both banks. The dam is 2,595 metres (8,514 ft) long with a maximum height of 47 metres (154 ft). The reservoir has a total volume of 1.58 cubic kilometres (1,280,000 acre·ft).

The navigation lock No.2 on the third channel was, when built, among the 100 largest in the world. The lock chamber is 280 metres (920 ft) long and 34 metres (112 ft) wide, with a minimum draft of 5 metres (16 ft) at the sill. It provides passage for 10,000 ton ships.

The Pubugou Dam is concrete face rock-fill embankment dam on the Dadu River, a tributary of the Yangtze River in Sichuan Province (located in southwestern China). The main purpose of the dam is hydroelectric power generation and its total generating capacity is 3,300 MW.

Construction started on March 30, 2004, the first generator was put into operation in December 2009 and the rest by March 2010. In 2004, the construction site was overrun by tens of thousands of protesters, though the only eventual result was the delay of construction by one year. The protests were about evictions stemming from planned flooding.

Jinping-I Hydroelectric Power Plant

Jinping-I Hydroelectric Power Plant
The Jinping-I Hydropower Station or Jinping-I Dam, Jinping 1st Cascade or Jinping No.1 Hydraulic Power Station is a large hydroelectric project on the "Jinping Bend" of the Yalong River (Yalong Jjiang) in Sichuan, China. Construction on the project began in 2005 and when complete, it will have a 3600 MW capacity to produce between 16 and 18 TW·h (billion kW·h) annually. Supplying the power station will be a reservoir created by a 305 m tall arch dam, soon to be the tallest in the world. The project's objective is to supply energy for expanding industrialization and urbanization, improve flood protection, and prevent erosion.

The Jinping 1 power station is on the border of the Yanyuan and Muli districts in the autonomous Liangshan Yi area of the Sichuan province. The Yalong River, which the dam will control, is the largest tributary of the Jinsha. For the project, approximately 7,500 inhabitants will be relocated.

The Jinping 1 power station will be supplied with water from a 7.7 billion m3 reservoir created by a 305m tall, 568m long thin double-curvature arch dam made of 7.4 million m3 of material. The power station will contain six 600 MW Francis turbines. Water discharged from the power station can then be diverted by the Jinping 2 Dam to the Jinping 2 Hydropower Station.

Xiaowan Dam

Xiaowan Dam
The Xiaowan Dam is a large hydroelectric arch dam on the Lancang (Mekong) River in Yunnan Province, southwest China. It is the world's highest arch dam and will be the second largest hydroelectric power station in China after the Three Gorges Dam. Construction started on 1 January 2002. The river was dammed in October 2004. The first generator was commissioned in September 2009 and the dam was complete in March 2010. The first generator was commissioned in September 2009 and the dam was complete in March 2010.

Xiaowan Dam is the highest arch dam in the world with height of 292 m (958 ft). It creates a 15,000,000,000 m3 (5.3×1011 cu ft) reservoir with an area of more than 190 km2 (73 sq mi). The hydroelectric power station will eventually consist of six generating units with generating capacity of 700 MW each. The total generating capacity of the project will be 4,200 MW. The first generator went into operation in September 2009 and the last one is expected in 2013. The cost of the Xiaowan hydropower station is estimated at ¥32 billion (nearly US$3.9 billion). The hydroelectric power station is being constructed and operated by Huaneng Power International.

Laxiwa Dam China

Laxiwa Dam
The Laxiwa Dam is an arch dam on the Yellow River in Qinghai Province, northwest China. It is 32 km (20 mi) downstream of the Longyangxia Dam and 73 km (45 mi) upstream from the Lijiaxia Dam. The main purpose of the dam is hydroelectric power generation and it supports the largest station in the Yellow River basin. The facility generates power by utilizing six turbines, each with a generating capacity of 700 MW, totaling to a capacity of 4,200 MW.

By the beginning of 2004, the Yellow River was diverted and in September of that year, excavation on the dam's abutment began. In April 2006, the first concrete was cast and on May 18, 2009, the power plant's first two generators were commissioned. A total of 79,571,000 cubic metres (2.8100×109 cu ft) of earth and rock were excavated from the dam site.

Jinping 2 Hydroelectric Power Plant

The Jinping 2 Hydroelectric Power Plant or Jinping 2 Dam, is a large conventional hydroelectic project on the "Jinping Bend" of the Yalong River (Yalong Jjiang) in Sichuan, China. Construction on the project began in 2007 and when complete, it will have a 4800 MW capacity. While the Jinping 1 will rely on its large dam and reservoir to supply water, the Jinping 2 will rely on four 16.6 km long headrace tunnels that are supplied with water which is diverted by a much smaller dam, which located 7.5 km downstream of Jinping-I dam.

Harnessing hydropower on the Jinping bend of the Yalong River has been in planning for decades. The length of bend is 150 km but the downstream part of the river on the opposite side is only separated by 16 km. Between that distance, there is an elevation drop of 310 m, creating an excellent situation for hydroelectricity production. Two projects were planned for the bend, the Jinping I and Jinping II with a combined capacity of 8,400 MW. Planning for the projects began in the 1960s under the former Sichuan and Shanghai design institutes along with the Ministry of Water Resources and Electric Power. They produced the "Reinvestigation Report on The Yalong River bend (Jinping)". In July 1965, the Jinping Hydropower Engineering Headquarters was set up and designs for the Jinping 1 and Jinping 2 would progress with the East China Investigation and Design Instititute.

Construction on the Jinping 2 started on January 30th of 2007 and is scheduled to be completed in 2014.

A 37 m tall, 162 m long sluice dam on the west-side of the Jinping bend will divert water into a 16.6 km long headrace tunnel towards the Jinging 2 Power Station. At the power station, the water will spin eight 550 MW Francis turbines with a total capacity of 4400 MW before being discharged back into the river. The dam will be made of 3.4 million m3 of material.

Xiangjiaba Hydroelectric Dam

Xiangjiaba Hydroelectric Dam
The Xiangjiaba Hydorelectric Dam is a large conventional hydroelectric dam on the Jinsha River, a tributary of the Yangtze River in Yunnan Province and Sichuan Province, southwest China. Xiangjiaba Dam is the second largest hydropower project in China after the Three Gorges Dam. As part of a cascade of dams, including the Xiangjiaba, Baihetan, and Wudongde, the Xiluodu seeks to alleviate much of the sedimentation that has been rapidly accumulating behind the Three Gorges. Together with Xiangjiaba, it will generate 12.6 Gigawatts of energy, roughly equal to the Three Gorges's maximum capacity expected in 2015. It will also displace an estimated 180,000 people, mostly from the city of Zhaotong. The Xiangjiaba Dam facility runs on eight turbines, each with a capacity of 800 MW, totalling the generating capacity to 6,400 MW. When completed, it will be the fourth largest dam in China. Construction started on November 26, 2006, and is scheduled for completion in 2015.

Xiluodu Hydroelectric Dam

The Xiluodu Hydroelectric Dam is a conventional hydroelectric dam project on the Jinsha River, i.e. the upper course of the Yangtze River in China. In early 2005, the Chinese government halted the construction due to lack of environmental impact studies. Later, construction was restarted. If completed, the Xiluodu Dam will be the third tallest dam in the world and a key component of the Jinsha project. The total generating capacity will be 13,860 MW.

The dam site is located near Xiluodu Town, the county seat of Yunnan's Yongshan County. The other side of the river is in Sichuan's Leibo County.
