The Danish company first established a base in Tianjin in 2006, when it built a wind turbine blade plant, expanding it later to include a generator factory. The latest CNY 1.8 billion (more than £220 million) expansion adds production of control systems and machined parts, as well as additional capacity at the generator and blade factories. The company is also opening a new supply and logistics centre for internal parts for turbine towers, it says. In total, Vestas has invested more than CNY 2.5 billion ($380 million) in its Tianjin base, representing more than 70% of its total investments in China. He Dexin, president of the China Wind Energy Association, says the introduction of the control system plant and the production technology will help raise the overall technological standard of the Chinese turbine industry.
