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
Gorges State Park recovered from the interference of man to provide a thriving and unique habitat. One of the most damaging interferences to the Gorges environment occurred in 1916 when the dam containing Lake Toxaway broke.

Following the flood, local citizens eventually sold large land tracts in the Gorges to Singer Sewing Machine Company, which logged most of the land.
