07 七 10 Global wind turbine giant intensified patent lawsuit
Currently, wind power generaotor is in the process of industrialization. U.S. Department of Energy released data show that the total U.S. wind power installed capacity of 2.47 MW from 1999 to 2009 of 34.86 MW. In 2007 to the end of 2009 these 3-year growth is particularly rapid, the additional capacity of nearly 2000 to 2006, 7 years to 3 times the additional capacity.
Since 2002, the U.S. patent issued over 800 wind turbine parts. Denmark’s Vestas Wind Systems, Germany 阿洛伊斯沃 this, Japan’s Mitsubishi Heavy Industries and General Electric are the United States holds the patent more than wind turbines. GE’s small wind turbines in which nearly 150 patents, came out top. General Electric is the largest U.S. supplier of wind turbines. According to the American Wind Energy Association estimates that in 2008 the U.S. General Electric wind turbines account for 43% of the market, and has more than 10 companies through licensing its patented technology. However, GE’s market dominance by Mitsubishi Heavy Industries challenges. Mitsubishi Heavy Industries in 2007, announced its 2.4 MW wind turbine units in the United States has received 411 orders. Alone order to close the nation’s total installed capacity by 2009 3 times. General Electric in early 2008 in the United States International Trade Commission (ITC) launched 337 proceedings, sued Mitsubishi for infringement of common wind turbine U.S. patent US5, 083,039; US6, 921,985, and US7, 321,221.
International Trade Commission in March 2008 filing, investigation. August 2009, the International Trade Commission administrative judge initially determined that Mitsubishi Heavy Industries and ’985 ’039 patent infringement, but did not infringe ’211 patent. However, the International Trade Commission’s unfair import investigations office Quedui administrative judge’s decision contended that General Electric Mitsubishi Heavy Industries, did not violate the patent, because General Electric is not in the United States of its patented technology, which does not meet under the Section 337 rule out the Mitsubishi wind turbine requirements.
January 8, 2010, the International Trade Commission’s six members of the Mitsubishi Heavy Industries of determination after review of the wind turbine generator does not infringe GE’s patents, without violating Section 337, so as to Mitsubishi 2.4 megawatt wind generators into the U.S. market exclusion a roadblock. However, General Electric, do not be to hand over the market, claiming to appeal the ruling of the International Trade Commission, and on February 11, 2010 Federal District Court in Texas alleging infringement of its U.S. patents Mitsubishi Heavy Industries, US6, 879,055 and US7, 629,705. In this regard, Mitsubishi Heavy Industries is not weakness, in the May 20, 2010 in the United States Court of Arkansas Western Federal antitrust suit against General Electric violations, abuse of patent litigation against competitors, threatening small wind turbine users. On the same day, Mitsubishi Heavy Industries is also in Central Florida to the Federal Court infringement lawsuit against General Electric, U.S. Patent US7, 452,185.

29 六 10 Wind power equipment kept hidden
Domestic wind power generator equipment manufacturers, although currently occupy a larger market share, but policy changes and external factors of wind power’s Input in Manufacturing, will be in China’s growing wind power industry to increase market uncertainty.
The giant fans abroad continues to increase investment in the domestic wind power market, continuously adjust the product direction and marketing strategy. The world’s largest small wind turbines equipment manufacturers Danmaiweisi Tass in 2009 to spend three billion yuan into China, respectively in Hohhot, Inner Mongolia, Tianjin and Jiangsu Xuzhou plant.
Relevant persons, foreign giants optimistic about China’s wind generator market, in addition, there is also an important goal is to build in China, global wind power industry, equipment manufacturing base.
Wind power industry in China has gradually and constantly expanding market scale of the new situation, the national level to continuously enhance the manufacturing wind power Shebei He Xin Jishuyanfa He Dianwang access, transport, storage of high and new technologies specific to support R & D Fangmian efforts to promote the wind power industry to achieve “large amount of high quality” of rapid growth.
Restructuring the industry to see mountains and rivers
The development of any business are small to large, no SME development, can not produce new large-scale enterprises. Geely cars are hot nowadays, came also from the development of SMEs, access standards if there were to be turned away, there would be no 1.8 billion today, Geely Automobile has bought Volvo, wind power equipment industry, too, constraints in the standard will have its own development policy.
China wind power equipment wind turbines manufacturing companies have sprung up, but the core technology and key components such as most of line to go is to introduce the core technologies become increasingly apparent absence of defects. China’s rapid development of wind power equipment manufacturing industry, this is a good thing, but separate ways capital herd phenomenon of the non-rational development, it became a bad thing. National policy of promoting wind power and equipment is of course a good thing, but some manufacturers blindly launched and hankered for large ocean, the lack of its own core technologies and R & D capabilities, difficult to form independent intellectual property rights, restructuring is inevitable mountains and rivers.
Encouraged by the policy, launched around the rush of wind power projects, although in China the upper hand electrical equipment wind generators manufacturers the world’s fastest growing companies. But those behind the industry efforts, can not allow to bathing, wind power equipment related to the development of wind power in China, let us hand in hand.

18 六 10 Irish Sea built the world’s largest wind power park
A huge energy plant is taking shape: the construction of the Irish Sea is the world’s largest wind park. The project by Siemens, RWE, StadtwerkeMünchen utility company building the implementation capacity to meet the 400,000 British households each year demand for electricity.
Not only the size of the name of a wind energy park is also unusual: “GwyntyMôr” (Welsh: Sea of Wind). Four years later, a wind energy park will be incorporated into power: According to RWEInnogy, Siemens and StadtwerkenMünchen utility company’s plans, the Welsh coast Siemens will build 160 wind turbines with a total installed capacity of 567 MW, is by far the world’s largest marine facilities.
Covering a wider area: North Wales coast 13 kilometers before the coverage area of 124 square km area, covering an area of small wind turbines for the 79 square kilometers of electricity to meet the 400,000 families every year demand for electricity. “GwyntyMôr” will be completed by 2013, electricity began in 2014.
Throughout the project, responsible for renewable energy projects in the RWE subsidiary of investment accounted for 60%, Stadtwerk companies accounted for 30%, Siemens 10% investment. The three companies plan to invest a total of more than 20 billion euros.
Slow pace of offshore wind development in Germany
Although the “GwyntyMôr” is by far the world’s largest investment and construction has started wind power park, but other projects are relatively slow pace of implementation. Program’s largest wind power park is located near the northern Hai Duoge Beach, plans installed capacity of 9000 MW, the generating capacity equivalent to seven nuclear power stations.
This project is RWE’s fifth wind park project. By 2025, renewable energy generation in the RWE Group’s share of places will increase from less than 5% now to 30% – of which offshore wind park will play a big role. RWEInnogy head FritzVarenholt that renewable energy building, the group invested about 1.4 billion euros per year, equivalent to a quarter of total investment in wind power generation.
However, Varenholt the construction of offshore wind power in Germany expressed dissatisfaction with slow speed. He said: “We can not wait the time.” Building of the eastern North Sea wind park grid connection cable, works to continue for three years. “This is a can not we accept.”
