The Three Gorges Project is the largest hydropower station in the world with 26 sets of 700MW hydropower units. International tendering with export credit was adopted for the fourteen units on the left bank. It was requested in the tendering documents that foreign companies should jointly design and jointly manufacture the equipment with qualified Chinese manufacturers and foreign companies should transfer their technology to Chinese manufacturers. The participation percentage of Chinese manufacturers should not be lower than 25% of the total contract value. And the last two units will be mainly supplied by Chinese manufacturers. Alstom won eight units co-operating with Harbin Electrical Machinery Company Limited while VGS won six units working with Dongfang Electrical Machinery Company. The contracts are proceeding smoothly. Harbin and Dongfang digested assimilated the transferred technology based on their technology tackling activities carried out in the passed two decades for large hydropower units. They conducted certain technology innovations and tried to be self-reliant on developing, designing and manufacturing large hydropower units. The 12 units on the right bank will mainly be manufactured by Chinese manufacturers, which laid a foundation for supplying good quality, advanced and reliable units for large hydropower stations in China.
