The company said it has maintained a good balance this year between power generation and other functions, such as flood control, navigation, drought relief and water supply.

STGC chairman Lu Chun said that the company wants to double its generation capacity to more than 100 million kW by 2020, which will make the company the world's top producer of clean energy.
