hina, a country with one of the world’s largest wind energy potentials, has seen tremendous growth in its wind power development in recent years. Yet Chinese manufacturers are still struggling to break into their own nation’s lucrative wind turbine industry. In 2005, domestic companies accounted for only 23 percent of
Since the 1990s, major European turbine manufacturers have gradually taken the Chinese market with the support of low-interest loans and incentives from their governments. The sudden rise in market demand in the past three years, however, has served as a wake-up call for domestic producers, by discovering that they lag far behind their European counterparts in both technology and scale.
The typical mainstream Chinese wind turbine has a capacity of 750 kilowatts (kW), while most European products generate more than 2,000 kW. (In 2005, REpower of Germany installed an experimental 5,000 kW turbine, currently the world’s largest, at a wind farm in

The Leap-Frog affect
Chinese turbine industry is playing much-needed catch-up. A common method for acquiring technology in recent years has been to purchase production licenses from foreign counterparts, even though most of the more accessible technologies are outdated. “This is a dead end. Most of the technology is already 10 to 15 years old,” says Wang Wenqi, a senior expert in the wind industry and the former general manager of
Another way is to set up joint ventures with international wind turbine giants. This is unlikely to happen, however, due to foreign concerns about nurturing the potential competition. In the 1990s, in a push to enter
The more feasible alternative will not only provide catch-up but a leap frog affect. Says Wang; a far better way is to cooperate directly with foreign turbine designers, rather than with the large manufacturers. L’Aerodyn, an independent German company that designs turbines for medium- and small-scale European producers, recently collaborated with four leading Chinese electrical equipment makers. This is a far more practical arrangement, according to Wang: “The cost of design is only one-third of license purchase. Through joint design, we get the core technology, and we own the intellectual property rights.”
Experts believe the key for domestic producers is to build up their own innovation capacity. “Without your own R&D capability, you will not know what technologies you should bring in, and you will not know how to digest them even if you have brought them in, let alone make innovations based on them,” explains He Dexin, president of the Chinese Wind Energy Association. He believes domestic manufacturers should stop trying to obtain core technology from overseas. “Core technology can only be generated through self-innovation efforts,” he contends.

The technical unit of Shenyang Univ.ersity (Liaoning Province) has undertaken the national Ministry of Science and Technology’s (MOST) 863 project “Megawatt variable speed, constant frequency wind turbine” in China’s “tenth” five-year plan. The finished prototype has successfully been erected and connected to the grid and generating in
In the design process, the team compiled three standards of the national wind electric power industry. It obtained 4 National Patents and is undergirded by academic research papers, published in domestic and foreign journals and specialized conferences. Presently, it has established the goal of a “2.5 Megawatt variable speed, constant frequency, wind turbine and offshore wind turbine system”, in order to develop wind turbine equipment with complete “independent” intellectual proprietary rights. This will reduce wind turbine price, strengthen
