The Tianshengqiao-I Dam (locally abbreviated as TSQ-I) is a concrete face rock-fill embankment dam and hydroelectric power station on the Nanpan River straddling the border between Guizhou and Guangxi, People's Republic of China, located in the counties of Anlong and Longlin. The dam is 178 m (584 ft) tall, and was completed in 1998. Water from the dam's reservoir powers four generators with Francis turbines, each with a capacity of 300 MW . [1] Water released from the dam also powers Tianshengqiao-II Dam (TSQ-II) downstream. The power is transmitted to Guangzhou via HVDC Tian-Guang and an AC powerline.

Embankment dam large artificial dam

An embankment dam is a large artificial dam. It is typically created by the placement and compaction of a complex semi-plastic mound of various compositions of soil, sand, clay, or rock. It has a semi-pervious waterproof natural covering for its surface and a dense, impervious core. This makes such a dam impervious to surface or seepage erosion. Such a dam is composed of fragmented independent material particles. The friction and interaction of particles binds the particles together into a stable mass rather than by the use of a cementing substance.

Unbong Dam

The Unbong Dam, or Yunfeng Dam, is a concrete gravity dam on the Yalu River which borders China and North Korea. It is located 33 km (21 mi) northeast of Ji'an in Jilin Province, China and Chasŏng in Chagang Province, North Korea. The primary purpose of the dam is hydroelectric power generation and it supports a 400 MW power station. Construction of the dam had initially began in August 1942 but was halted in 1945 after the surrender of Japan ending World War II. In October 1959, construction on the dam recommenced and in September 1965, the first of the four 100 MW Francis turbine-generators was operational. The last generator was operational on 4 April 1967. The 113.75 m (373 ft) tall dam creates a reservoir with a storage capacity of 3,895,000,000 m3 (3,157,728 acre⋅ft). The dam's spillway is an overflow type with 21 floodgates and has a maximum discharge of 21,900 m3/s (773,391 cu ft/s). The dam is located before a bend in the river and its power station is located on the other side of a ridge that meets the dam’s right abutment. Water is delivered to the power station via two tunnels, 775 m (2,543 ft) and 759 m (2,490 ft) long. Generators 1 and 3 deliver power to China while 2 and 4 deliver to North Korea.

Coo-Trois-Ponts Hydroelectric Power Station architectural structure

The Coo-Trois-Ponts Hydroelectric Power Station is a pumped-storage hydroelectric power station located in Trois-Ponts, Province of Liege, Belgium. Located next to the Amblève River, the power station uses its water to support a power scheme where water is pumped from a lower reservoir to one of two upper reservoirs known as Coo I and Coo II. When energy demand is high, water can be released from these reservoirs for power generation. The water then returns to the lower reservoir and the process repeats as needed. The same machines that pump the water to the upper reservoirs at a higher elevation are also used as generators. The plant was commissioned in two stages, Coo I (1969) and Coo II (1978). It is owned by Electrabel and has an installed capacity of 1,164 MW.

Shweli I Dam

The Shweli I Dam is a gravity dam on the Shweli River about 23 kilometres (14 mi) southwest of Namhkam in Shan State, Burma. The primary purpose of the dam is hydroelectric power generation and it supports a 600 megawatts (800,000 hp)power station. Water from the dam's reservoir is diverted through a 5.1 kilometres (3.2 mi) long headrace tunnel to the power station downstream. The drop in elevation affords a hydraulic head of 299 metres (981 ft). Construction on the dam began in 2002 and the river was diverted on 10 December 2006. On 5 September 2008, the first generator was commissioned and the last of the six was commissioned in April 2009. The dam and power station was constructed under the build–operate–transfer method and cost US$756.2 million. It is owned and operated by the Shweli River-I Power Station Co. The Shweli II and Shweli III Dams are planned downstream.
