All power units constructed at major hydropower station in Yunnan

All power-generating units of the Baihetan hydropower station in southwest China have been constructed, marking a major step toward the full operation of the mega project, according to the hydropower station.

All units are due to be operational by the end of the year. Baihetan will then be the world's second-largest hydropower station in terms of total installed capacity, second only to the Three Gorges Dam project in the central Chinese province of Hubei.

The hydropower station is located on the Jinsha River, the upper section of the Yangtze River in southwest China. It straddles the provinces of Yunnan and Sichuan.
