China Three Gorges Corp. has awarded Voith a US$407.4 million contract to supply six hydroelectric turbine generator units and auxiliary parts to the 10.2-GW Wudongde hydropower station.
The equipment adds a total installed capacity of 5.1 GW to the plant that is being constructed on the Jinsha River, a tributary of the Yangtze River in Sichuan and Yunnan provinces, southwest China.
The US$15.4 billion Wudongde plant will be China's fourth-largest hydroelectric facility once completed and commissioning is expected in 2020, according to a press release from Voith.
A total of 12 units at the facility, each 850-MW Francis turbine generators, will generate energy. In addition to the Voith-supplied equipment, CTG awarded GE a contract last December to supply six 850-MW Francis turbine generators and related equipment for the project. The amount of the GE contract is not immediately available.
Voith said its turbine generator units for Wudongde will be amongst the largest worldwide and will also be the largest it has supplied so far in terms of power output.
Construction of Wudongde was approved by the Chinese government in December 2015, and the project is expected to generate 38.9 billion kWh of clean electricity every year.
The project will contribute to savings of 12.2 million tonnes of standard coal and 30.5 million tonnes of CO2 emissions per annum, according to published reports.
China currently has about 330 GW of installed hydropower capacity and in 2014 the country added 21.85 GW.
