Three Gorges Dam – Changzhou (3,000 MW), and HVDC Gezhouba – Shanghai (1,200 MW). The alternating current (AC) lines to the Central China Grid have a total capacity of 12,000 MW. The DC transmission line HVDC Three Gorges – Guangdong to the South China Grid has a capacity of 3,000 MW. The dam was expected to provide 10% of China's power. However, electricity demand has increased more quickly than previously projected. Even fully operational, on average, it supports only about 1.7% of electricity demand in China in the year of 2011, when the Chinese electricity demand reached 4692.8 TWh. According to the National
Three Gorges Dam of the lift will be 21 minutes. It says that the expected dimensions of the passenger vessels the ship lift's basin was designed to carry will be X X . The moving mass (including counterweights) is 34,000 tonnes. The trials of elevator finished in July 2016, the first cargo ship was lifted in July 15, the lift time comprised 8 minutes.
