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 . 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.
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.
The Nanpan River has its source in the Yungui Plateau of eastern Yunnan Province. It then flows east, forming part of the border between Guizhou and Guangxi provinces. It joins with the Beipan River to become the Hongshui River.
Guizhou, is a province of the People's Republic of China located in the southwestern part of the country. Its capital city is Guiyang. Guizhou is a relatively poor and economically undeveloped province, but rich in natural, cultural and environmental resources. Demographically it is one of China's most diverse provinces. Minority groups account for more than 37% of the population.

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.
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.
