How did the Three Gorges Dam generate electricity for Hubei and nearby provinces?

The Three Gorges Dam, located on the Yangtze River in Hubei province, generates electricity through a massive hydroelectric power station equipped with 32 main turbine generator units and two additional generators.12

These units provide the dam with a total installed capacity of 22,500 megawatts, making it the most productive hydroelectric facility in the world. Following the commencement of limited power production in 2003, the station gradually increased its output as additional turbines came online, reaching full generating capacity in 2012.12

The electricity produced is distributed eastward to Hubei and several adjacent provinces via an extensive network of transmission lines, which extend as far as Shanghai on the East China Sea coast.12
