Three Gorges Project

2017-12-29

The Three Gorges Project maintained a sound performance in 2016, thanks to steady dam operation, safe and stable power units, and highly efficient ship locks. The ship lift began it’s trial navigation also in this year, and comprehensive benefits of flood control, power generation, shipping and water replenishment were delivered.

Flood Control and Water Replenishment
During the 2016 flood season, when catastrophic flooding hit the middle and lower reaches of the Yangtze River, the Project retained 12.3 billion cubic meters of floodwater through joint operation of the basin’s cascade complexes. The project contributed greatly to flood control and disaster relief in face of 50,000 cubic meters per second peak flow and avoided the overlap of “No. 1 flood peak” and “No. 2 flood peak”. At the same time, the Three Gorges reservoir had achieved its 175m impoundment target for seven consecutive years, and replenished 21.76 billion cubic meters of water flowing downstream in the dry season.

Improving Shipping Conditions
By 2016, the ship locks has been operating efficiently and safely for 13 consecutive years, and hit a record high with approximately 120 million tons of cargo. In addition to a 98% navigation rate, the ship locks also registered a 100% key equipment readiness to ensure smooth navigation along the Yangtze River. Also, the ship lift entered its trial stage on September 18 and ran soundly and safely afterwards; 240 vessels, 2,144 passengers and 24,169 tons of shipment were passed in 232 runs of the lift throughout the year. The Three Gorges Project has become open to greater sea traffic.

Protecting the Environment
In April 2016, CTG released 2,020 large-sized Chinese sturgeons back into the Yangtze River; this was the 58th time in a row, setting another record in such activity in terms of average body length and weight. For the first time, satellite marker technology was used to track and monitor the released Chinese sturgeons, which allowed us to obtain preliminary information on the living conditions of this species in the sea.
In June 2016, we combined flood control efforts with the natural reproduction of four major breeds of Chinese domestic fish through ecological operation.
In 2016, we intensified research and protective efforts of rare and endemic fishes in the Yangtze River, and once again observed the spawning of wild Chinese sturgeons at an interval of 3 years.

Providing Clean Energy
In 2016, the power units of the Three Gorges Hydropower Station generated 93.53 TWh of electricity. Through joint operation of cascade reservoirs in the basin, optimal regulation against medium and small floods, flotsam elimination for good water head, and intensified grid output coordination, we made good utilization of the floods for higher power efficiency of the Three Gorges-Gezhouba cascade plants. In 2016, we generated an additional 6.44 TWh of electricity, including 4.86 TWh from the Three Gorges Dam and 1.58 TWh from Gezhouba Hydropower Station.


TGP mitigates flood risks, contributing greatly to disaster relief.

On the afternoon of September 18, 2016, the “TG 9” passenger liner was shipping into the ship lift chamber, with signaled the beginning of trial operation of the ship lift and the completion of the project construction.

CTG organizes the Chinese Sturgeon release activity every year.

TGP provides clean energy to many parts of the country.
