Tokyo, Japan [RenewableEnergyAccess.com] Mitsubishi Heavy Industries, Ltd. (MHI) and Wuzhong Instrument Co., Ltd. (WUYI) have signed an agreement under which MHI will license production technology of its wind turbine MWT 62/1.0 (also known as MWT-1000A), which has a rated power output of 1 MW (megawatt), to WUYI.
The mid-size wind turbine in the 1 MW class was selected for licensing as it is difficult to transport large-size wind turbines to the hilly zones of the Ningxia Hui Autonomous Region, which offers abundant wind energy. NXEPG, the parent company, plans to build its own wind power generation farm. The 1 MW wind turbines produced by WUYI will be supplied not only to NXEPG but also to other electricity companies for their wind farms.
The MWT 62/1.0, with more than 700 units in operation globally, is capable of generating power even at relatively low wind speeds thanks to its optimized blade structure and redesigned blade shape. With these improvements, in an environment where the annual wind speed averages 6 meters per second, the MWT 62/1.0 can achieve 20% higher annual energy production (300 MWh/yr) than with MHI’s conventional 1 MW wind turbines (MWT 57/1.0 or MWT-1000).
WUYI is a group company of Ningxia Electric Power Group Co., Ltd. (NXEPG), which is a mid-sized electricity provider established in June 2003. The company has generation capacities of 1,320 MW in thermal power and 162 MW in wind power, and also owns a wind turbine production facility. Both companies have their headquarters in the Ningxia Hui Autonomous Region.
As of the end of 2006 China has total wind turbine installations equivalent to 2,588 MW, putting the country sixth worldwide in terms of cumulative wind turbine installations. In terms of new installations completed in 2006, China ranked fifth at 1,334 MW.
In the runup to the 2008 Beijing Olympic Games, China is planning to expand its wind power generation capability at an annual rate of approximately 2,000 MW. In January 2006 it implemented a new Renewable Energy Law, and the country is now targeting wind turbine installations of 5,000 MW in 2010 and 30,000 MW in 2020.
