Three Gorges Hydropower Plant

Three Gorges Hydropower Plant operates and manages the largest hydropower station in the world——the Three Gorges Hydropower Station,

which consists of 26 units on the left and right banks (with unit capacity of 700MW), 6 units in the underground power station (with unit capacity of 700MW), and 2 units in the power supply station (with unit capacity of 50MW), and has a total installed capacity of 22,500 MW. The Three Gorges Hydropower Station, located in Sandouping, Yichang City, Hubei Province, the middle section of the Xiling Gorge of the Yangtze River, is the center of the national power network, connecting power grids of the East China, Central China and the South. Being the key power supply point of "west-east power transmission", cumulative power generation of the Three Gorges Hydropower Station over the years has exceeded 900 TWh as of January 2016.

With the pursuit of the international first-class standard, the Three Gorges Hydropower Plant has reached an installed capacity of 50 MW per capita, created the new hydropower construction and operation mode "combination of construction and management and seamless handover", and established and improved the lean production and management by operation diagnosis, lean maintenance and responsibility system. The Company provides an operation and management mode that can be referenced and used by the domestic and foreign large-scale hydropower stations.

Gezhouba Hydropower Plant

Gezhouba Hydropower Plant is the operation and management unit of the Gezhouba hydro-project. Gezhouba Hydropower Station is the largest low

water head runoff hydropower station, with 21 designed units, and total installed capacity of 2,715MW. A 20MW unit was added as the emergency power supply in 1996, and the unit transformation to increase capacity has been gradually implemented as scheduled since 2005.
