This means that about 2x9.8x1245000=2.4x10 7 kN of gravitational potential energy is converted every year. The Three Gorges ship lift can carry 3000-ton ships, with a maximum climbing capacity of 15500 tons and a maximum climbing height of 113 meters. It can realize 6000000 tons of dam passing per year.
