The Gechzhou Dam on the Yangtze River for Water Control ( Chinese р 葛洲坝 水利 枢纽 工程 , pinyin : chángjiāng gězhōubà shuǐlì shūniǔ gōngchéng ), or Gaezhouba , is located in the western part of the city district of Yichang , Hubei Province . The dam is located several kilometers upstream from the center of Yichang, downstream from the confluence of the Huangbo River into the Yangtze.

Content
Construction began on December 30, 1970 and ended on December 10, 1988. The dam has a total installed electric capacity of 2715 MW [1] .
After passing through the Nanjin Gorge, the Yangtze River slows down and expands from 300 meters to about 2,200 meters at the dam. Two small islands - Gaezhouba and Siba - divide the river into three channels.
The facility has a generating capacity of 2.71 GW, as well as three ship locks, two power plants that generate 14.1 billion kWh of electricity per year, 27 gates of a spillway, and counter-current fortifications on both sides of the dam.
The dam is 2595 meters long with a maximum height of 47 meters. The tank has a total volume of 1.58 cubic kilometers.
The shipping lock No. 2 on the third channel entered, when it was built, among the 100 largest in the world. The lock chamber is 280 meters long and 34 meters wide, with a draft of at least 5 meters in depth. It provides passage for ships with a displacement of 10,000 tons.
Economic Significance
Gezhzhuba HPP is the first major hydraulic project of the PRC on the Yangtze River , providing coverage for the annual increase in electricity consumption in the 80s of the 20th century.
After the completion of the Sansya ( Three Gorges ) hydroelectric power station upstream, the hydroelectric power station became a counter-regulatory hydroelectric complex for this more powerful hydroelectric power station, which reduces the restrictions on the Three Gorges hydroelectric power station for regulating the power grid.
Thus, these two power plants are one of the main centers of China's unified energy system.
