All hydro-generating units of the Baihetan hydropower station in southwest China went fully operational on Tuesday.
The Baihetan hydropower station is the world's second-largest in terms of total installed capacity, second only to the Three Gorges Dam project in the central Chinese province of Hubei.
The hydropower station, straddling the provinces of Yunnan and Sichuan, is located on the Jinsha River, the upper section of the Yangtze River.
It transmits electricity from the resource-rich west to energy-consuming regions in the east.
Baihetan has a total installed capacity of 16 million kilowatts. It is equipped with 16 hydro-generating units, each with a capacity of 1 million kilowatts, the largest single-unit capacity in the world.
