The Lijiaxia Hydroelectric Dam is a concrete arch-gravity dam on the Yellow River in Jainca County, Qinghai Province, China. The dam houses a hydroelectric power station with 5 x 400 MW generators for a total installed capacity of 2,000 MW. Construction began in April 1988 and the reservoir began to fill on December 26, 1996. On January 26, 1997, the initial reservoir operating level was reached and the first generator was commissioned in February.

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.

Here, after rushing out of Nanjin Pass ("South Ford Pass"), the Yangtze River slows down and widens from 300 m (980 ft) to about 2,200 m (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 Gezhouba Hydroelectric Power Plant 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 m (8,514 ft) long with a maximum height of 47 m (154 ft). The reservoir has a total volume of 1,580 m³ (55,797 cu 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 m (920 ft) long and 34 m (112 ft) wide, with a minimum draft of 5 m (16 ft) at the sill. It provides passage for 10000 ton ships.

The Ertan Dam is a large concrete arch-gravity dam on the Yalong River, a tributary of the Yangtze River in Sichuan Province, southwest China.

The dam has six hydroelectric generators, each with a generating capacity of 550 MW. The total generating capacity of the facility is 3,300 MW, one of the largest hydroelectric stations in China. The annual production is 17 TWh, and until December 5th 2006, it has produced over 100 TWh of electricity. Construction of the dam started on September 1991 and was completed on December 26, 1999.

Ertan was China's first hydropower plant to be built through international bidding. Canada's General Electric Co (GE) won the contract for the manufacture of the six generating units. The contract called for GE to manufacture the first two 582MW Francis turbines in Canada, while the third and fourth would be a joint project of GE and Harbin Electrical Machinery Works in northeast China's Heilongjiang Province and the Shanghai-based Dongfang Electrical Machinery Works. The fifth and sixth would then be produced by the Chinese firms alone. Dongfang in particular is an important partner for GE. In September 1999, Ertan unit five, the first Chinese domestic-made 550MW hydropower generator, went into formal operation. The previous largest hydro turbine built in China was 320MW. Dongfang and Harbin have also formed a joint venture company with Austria's VA Technologie for domestic hydro turbine production.

Longtan Hydroelectric Dam is a large roller-compacted concrete (RCC) gravity dam on the Hongshui River, China, a tributary of the Xi River and the Pearl River. The dam, will be 216.2 m (709.3 ft) when completed.

The attached ship lift is said to be the fastest in the world. The facility is located in Tian'e County of the Guangxi Zhuang Autonomous Region, not far from the border with Guizhou. The dam's first of three operational hydroelectric generating units was testing May 2007. When completed, in 2009, Longtan Hydroelectric Power Plant has nine turbines will have a total generating capacity of 6,426 MW, and is expected to generate 18.7 TWh of electricity annually.
