Giant hydropower plant fully operational

The last generator of China's Three Gorges Dam on the Yangtze River went online yesterday, meaning that the world's largest hydropower plant has become fully operational.

Launched in 1993, the project's original plan called for the 26 generators to produce 84.7 billion kWh of electricity annually after its completion.

This was later expanded to include six more turbines installed underground by 2012 to reach a capacity of 22,500 MW.
