admin — Thu, 29 Jul 2010 14:24:07 +0000

The wind power companies and power companies must be truthful and complete record and preserve the power of wind power projects online transactions, price and amount of subsidies, etc.; pricing departments at all levels should strengthen the implementation of wind power generators electricity price and electricity price by an additional subsidy settlement control to ensure the implementation of wind power electricity price policy in place.
At present, the investment enthusiasm of wind power industry, “notification” release specifications of wind power electricity problems, small wind turbines encourage the development of quality resources to ensure the orderly development of wind power. Help reduce costs and control costs. Lower project costs, better management, higher earnings, wind power companies continue to encourage lower investment costs and operating costs. In addition, wind power market to ensure orderly conduct.

90% of wind power equipment business will disappear?

admin — Tue, 27 Jul 2010 12:12:10 +0000

If China’s wind power generator equipment, high quality, cheap, and have core technology, then we have a competitive edge in the international arena, they are not afraid of overcapacity. However, slow innovation and development of domestic enterprises will make a large number of wind power company, overheating in the next 35 years was eliminated.
Around half of last year wind generators overproduction provoked intense controversy after all, since the beginning of this year, wind power equipment overheating, both inside and outside the industry a further focus. How hot wind power equipment in the end, the development of wind power equipment industry will go? With these questions, before reporters interviewed some experts and wind power turbines equipment manufacturing business owner.
Hot hot wind power equipment
July 6, China Agricultural Machinery Industry Association, wind power equipment branch of the Deputy Secretary-General, researcher Chen Dechang in an interview, said that in recent years, launched the domestic wind power equipment small wind turbines manufacturers is a bit too much too fast, the two figures to illustrate this point: the world total of about 140 or so wind power equipment manufacturers, including China, accounted for 90, and 90 domestic wind power equipment that most companies is the recent 34 years there and developed.
Qingdao Wind Power Technology Co., Ltd. Shenzhen Min Jiang Chunhui, general manager, told reporters: “At present domestic enterprises engaged in production of wind energy equipment, at least above 100.”
Shende Chang said that in order to support local industry, relevant government departments to request “wind power equipment localization rate to 70% or more, does not meet the requirements of equipment localization rate does not allow construction of wind farms.” It is encouraged by national policy, launched around the rush of wind power projects, China has become the upper hand electrical equipment manufacturers in the world’s fastest-growing state.
Chen Dechang further explained that this year will reach the domestic fan installed 30 million kilowatts, which is the state planning to the development of wind power by 2020 target, the development of wind power equipment is really too fast
Lack of innovation and lack of core technology
It is understood that by the end of 2004 opened the domestic wind power industry market, the beginning of States to guide the development of wind turbines industry, the “introduction – absorption – another new” line of hope in the joint design with foreign firms based on the realization of independent innovation .
Aspirations of the country is full of good intentions, but four years later, the majority of independent innovation of enterprises has been slow.
Jiang Chunhui said, the reality is the technology re-introduction, lack of innovation, lack of core technology. “Many companies, after obtaining the support of the local government invested little in the fund to build plants, then the introduction of the equipment assembly drawings in accordance with the foreign owners to sell wind, reap the profit center.”
Chen Dechang also used to prove the reality of another domestic wind power equipment manufacturer technical deficiencies. He said: “At present, 90 domestic enterprises, only 20 have the production conditions, the other still in the prototype development stage.”
Qin Haiyan of China Wind Energy Association to the Secretary-General’s analysis, wind power technology for domestic and foreign, are faced with many technical issues need to study, the first to master the technology grasps the initiative.
90% of businesses will disappear
3 end of the month, the Department of Industry and Information Technology, the National Development and Reform Commission, National Energy Board and the drafting of the three ministries, organizations of the “access for wind power equipment manufacturing industry standard (draft)”, the establishment of enterprises from the production, process equipment, and R & D testing, product quality and after-sales service, technical progress, energy saving and comprehensive utilization of resources and other aspects on wind power equipment manufacturers put forward specific demands.
Shende Chang said: “The access standards, in principle, means that no approval of the new enterprises to enter the wind power equipment.”
Well, the Chinese wind power equipment market, and can only put the number of family traditions of electrical equipment companies stay in business?
Qin Haiyan am rather optimistic. He told reporters: “By 2020, our non-fossil energy in the share of primary energy increased to 15%. To achieve it, we believe that wind power installed capacity to reach from 120 million to 150 million kilowatts. If 2020 is 120 million kilowatts, the next 10 years, the additional installed capacity per year at least 10 million kilowatts, so our domestic market potential is enormous. ”
However, Chen Dechang Quedui capacity of the domestic market to a decisive answer: the domestic market can only put up no more than 20 family traditions electrical equipment manufacturers.
Chen Dechang calculations to reporters, currently ranked the top 10 domestic wind energy equipment business, production accounted for 80% of the domestic market, pre-15 accounts for 95% of the market, and the remaining 5% of the dozens of good points, they can earn much money? An installed capacity of wind power equipment business volume of 500 thousand kilowatts in order to guarantee no loss, while the installed capacity of our country for one year a total of only 10 million kilowatts.
Shende Chang said: “The light does not make money making things definitely quit crying, the wind power industry in the next 35 years, certainly 90% of the wind turbine generator equipment company through restructuring, mergers and other channels disappear, even though each of these companies now is full of confidence. Only those products are technically advanced, stability, economy, equipment, better performance than similar products, technically innovative technology companies to stay perfect.

Experts should be assessing the proposed wind power grid electricity generating companies

admin — Fri, 23 Jul 2010 14:38:38 +0000

The National Development and Reform Commission experts in Feng-energy from closing in on July 8 2010 China (Jiuquan) New Energy and Industrial Exposition, said renewable energy wind power generation in order and full protection of the system corresponding to the acquisition, proposed installed capacity of wind power generation business ratio requirement is converted to grid electricity requirements.
State “long-term renewable energy development plan” put forward in 2010 and 2020, total installed capacity of wind power to the country to reach 5 million kilowatts, respectively, and 30 million kilowatts; equity total installed generating capacity of more than 5 million kilowatts of investors, the of non-hydropower renewable energy interests to be separately installed capacity to meet its total installed capacity of power generation interests of 3% and 8%.
Feng-play said: “The goal in this request, the generation companies and local governments will be installed capacity as a performance appraisal standards, wind speed Dianyuan construction increased significantly. Even there the project is not approved, start the construction of wind farms on the phenomenon of Some units are not followed by hoisting the Internet, unable to pronounce the power. ”
According to the China Hydropower Engineering Consulting Group Expert Committee Shi Pengfei introduced in 2009, new wind power installed capacity in China ranks first in the world, lifting capacity of 12.02 million kilowatts, but after debugging and a wind turbine power generation capacity of 8.28 million kilowatts More than 30% of installed capacity appear idle.
As of the end of 2009, China’s first 10 million kilowatts in wind power base in Jiuquan, Gansu Province, wind power installed capacity has reached 2.2 million kilowatts, but the actual grid power generation capacity of only 897,100 kilowatts fans.
Feng-play, said the revised “Renewable Energy Law,” proposed a full protective grid enterprises purchase renewable energy electricity generation Internet, also provides for the cost of power grid enterprises can do to increase renewable energy development fund to get assistance. Feng-effect that in order to correspond with the regulations, it is necessary to Wind Power Generation Enterprises in the proportion of consumption accounted for as a rigid goal should be finalized.

China’s five major challenges facing the offshore wind power

admin — Thu, 15 Jul 2010 11:58:40 +0000

With China’s offshore wind power concession bidding work started, the industry believe that 2010 will become the first year of offshore wind power generator development. The World Bank in June specializing in publishing a report that the Chinese Government plans to resource-rich and sparsely populated western region to expand the scale of wind power on land, carried out in the eastern coastal intertidal pilot wind turbineg generator project, and start in the deep waters of the wind farm development The strategy is feasible. Meanwhile, China’s development challenges facing the offshore wind, the Bank also carried out analysis:

First, the characteristics of wind energy resources to clear. Report, Liao Jie a high wind Texing right Jianshe De wind farm Zhiguanzhongyao, for example, Tong Yang a wind turbine, installed at an average annual wind speed 9m / s wind Chang installed in more than 6.5m / s wind field Fadian volume will double. If the wind is not doing enough work, it will lead to unreliable estimates generating capacity, to investment risks.

Currently, most of the coastal provinces of wind has a very limited, in fact, investment in wind farm compared to the input wind negligible: according to expert estimates, a cost of 2MW turbines can be used to build more than 50 wind tower.

Second, good project design, using sophisticated fans. As the complexity of the marine environment than on land, offshore wind power to solve any minor problems will have to pay a high price. At present the performance of Chinese-made fan not satisfactory and the import of design standards used by many fans according to the Nordic wind conditions, establish, and totally dependent on the unrealistic and unsustainable. World Bank suggested that the domestic large-scale fan manufacturers started cutting-edge technology research and development, a breakthrough by leaps and bounds. 4MW for the development of more large-scale offshore wind turbines, the government should give preferential policies to support.

Third, improve the supporting laws and regulations offshore wind generators. Currently, offshore wind power development in China is still a new thing, a lot of offshore oil and gas exploitation and shipping regulations are still being used for offshore wind power development activities in the examination and approval, this will result in time delays and increased project costs.

Fourth, strengthening the professional ranks. China to achieve large-scale wind power development requires construction of a large number of construction personnel and operating and maintenance professionals. This is a difficult task, even in Western countries there are also the same problem. Experts have estimated that due to shortage of qualified professional and technical personnel, coupled with poor operation and maintenance, to the American Wind caused damage amounting to 1% -2%.

5 is a network access problem. Shiji Shang, for any small wind generators project,, because of its power generation of the stability and non Yuce Bu Xing, and Wang will be a great issue and Military Maritime wind power is no exception. At present, China’s first offshore wind power demonstration project – Shanghai East Sea Bridge 10 to 34 thousands of Wahe upwind field units have been grid, but the East China Sea Bridge project and promising Expo “gift” of the task, and other offshore wind power project The grid-work may not have run so smoothly.

In this regard, the World Bank recommends that a National Grid Company, in consultation with industry associations on the basis of the views, clear the land of small wind turbines and offshore wind power and network technology requirements in order to minimize the uncertainty faced by developers. Approval of construction of the offshore wind power demonstration project, may consider providing free Internet access.

According to the American Wind Energy Association (AWEA) reports

admin — Mon, 12 Jul 2010 06:49:52 +0000

According to the American Wind Energy Association (AWEA) reports, 2009, the U.S. wind energy industry to achieve unprecedented rapid growth, adding 9,922 megawatts of generating capacity, enough to more than 2.4 million American families to provide clean energy. AWEA reports that in 2009, the U.S. wind and gas power generation is the main source of new power, the two together account for about 80% of new installed capacity. Wind energy industry’s rapid growth is mainly due to the promulgation in 2009 of “USA Recovery and Reinvestment Act.”

One of the beneficiaries of wind energy wind generator manufacturing industry. Last year, the U.S. wind energy machinery wind turbines manufacturing increased by 39%. Currently, the U.S. total wind power installed capacity of more than 35,000 megawatts, equivalent to 9.7 million households with electricity. 5-year wind industry average annual growth rate of 39% (2003 -2008 period, 32%).

China will dominate the global wind turbine equipment market

admin — Thu, 08 Jul 2010 03:19:30 +0000

Following the launch in the field of solar power price war hit Europe and the United States of crystalline silicon solar cell manufacturers profits, China has started to target the wind turbine market.

According to the Danish consulting firm BTM, although the Danish Vestas and General Electric is still dominated by the global wind turbine supplier in the first two top spot, but Chinese companies are catching up.

Sinovel China Technology Co., Ltd., Xinjiang Gold Wind Technology Co., Ltd. and Dongfang Electric Group Co., Ltd. are among the world’s top ten industries, while Chinese companies are competitive export market.

HSBC renewable energy, resources and energy project director RobertTodd said: “The (Chinese manufacturers) has established an international sales team is actively bid for overseas contracts. Their real progress is only a matter of time.”

Goldwind Monday said its in Chicago set up a wholly owned U.S. subsidiary, announced Goldwind to the market dominated by General Electric launched its attack. Goldwind previously set up production bases in Germany, last year set up a subsidiary in Australia.

Sinovel is China’s largest wind power generator equipment company, ranked third in the world. The company exports to India last year, 10 sets of 1.5 MW wind turbine, also in March the company purchased from American Superconductor electrical system for its self-developed 5-megawatt wind turbine use. Company plans to export such future large-capacity wind turbine.

In the solar power market, the price of Chinese products than similar products in Europe or the United States is much lower. Some people worry that this could depress prices of wind turbines, solar power market, leading to oversupply, repeat last year’s mistakes.

Export potential

Often people complain that the Chinese domestic market, blocking, or by providing huge subsidies and cheap loans way to help its exporters an unfair competition.

German solar company Conergy and Solarworld have told the Chinese solar panel small wind turbines manufacturers expressed strong concern about the pricing behavior.

But at least for now, the Chinese wind turbine manufacturers are still the focus of the domestic market, the pace of these companies overseas is not for many international companies have too much of a threat, especially considering the logistics required to transport these massive costs.

Siemens spokesman said: “The Chinese small wind generators manufacturers began to visit the overseas market, such as in India or the Asia Pacific region. But still the focus of Chinese domestic enterprises.”

China is the world’s largest wind energy market in 2009 to increase its wind power generators capacity of 1.3 megawatts or more, than the original doubled.

China’s domestic manufacturers of wind turbines now occupy 80% of the market, and in less than a decade ago, Vestas, GE and Gamesa and other foreign companies are major players in the Chinese market.

wind turbine generators Worries Three Gorges gamble

admin — Tue, 29 Jun 2010 08:28:47 +0000

The Jiuquan “wind of the Three Gorges” and matching the power of the electricity sent to East China, East China needs? East not only in the construction of onshore “wind of the Three Gorges”, but also building offshore “wind of the Three Gorges”
Wind power industry, bad news after another came.
May 28, held the State Grid Corporation of wind power development of the forum, outgoing government officials and reasonable public approval network refused to Wind Power generators news. According to the “Renewable Energy Law,” renewable energy power generation, power grid to be in full acquisition.
June 9, foreign media reported that the China Securities Regulatory Commission for fear of “overcapacity drag the renewable energy sector development, has ordered a halt to the renewable energy sector initial public offerings (IPO)”. Later, the SFC publicly refute rumors.
For these messages, engage fans in Beijing, Shanxi Merchants in the logistics business, cattle climb on the “Oriental Outlook,” said: “It will not affect the business, I was financing the purchase of transport vehicles, the state should build a lot of ‘wind of the Three Gorges’ fan logistics market is large indeed! ”
Bovine climb the stakes, “wind of the Three Gorges”, in the end will bring it?
“Wind Power of the Three Gorges” let equipment manufacturers “crazy”
Cow climb that a lot of wind power equipment through his logistics team is continuously sent to Jiuquan “wind of the Three Gorges,” which encourages his monopoly of wind power equipment logistics industry desires: “I will continue to invest in expanding towards monopoly the industry. ”
And cattle climb optimistic as there are businessmen in Zhejiang Yin Song.
2009, Yin Song in the “World Wind Library” Guazhou registered “top song of Gansu Guazhou Machinery Manufacturing Co., Ltd.”, specializing in tower fan parts cylinder. His “Oriental Outlook”, said: “Guazhou here is the Jiuquan wind ‘wind of the Three Gorges’ part of the building site is on fire, and our tower tube is very hot, do not feel anything unusual.”
Leading Enterprises in China Fan Manufacturing Goldwind also for business. January 26, Goldwind to 2009 net profit forecast from October 27, 2009 announcement of “an increase of 30% to 50%” substantially raised to “an increase of 75% to 95%.”
“Wind Power Three” for wind generators equipment manufacturers excitement, “crazy.” The industry often talk about a group of data: machine manufacturers in China the number of wind power has more than 70, more than 50 fan manufacturers, tower tube manufacturer, has nearly 100, and in the global context, outside of China the fan manufacturer to house only 10.
According to China’s wind power development, “building large bases into the major power” in the layout, built in 2020, Hami, Xinjiang, Gansu Jiuquan, West Inner Mongolia east, Jilin, Hebei, Jiangsu seven million kilowatts wind power bases, but also are the seven “wind of the Three Gorges”, National installed capacity of wind power may exceed 150 million kilowatts.
August 8, 2009, the world’s largest wind power base – 10 million kilowatts of Jiuquan wind power base construction.
However, in the State Grid Corporation of wind power development of the forum, State Grid Corporation of India deputy general manager of Shu Biao response “to wind power is difficult,” “a large number of wind turbine idling” when the accused, said issues such as: wind power generator development without planning, consumer accept the direction is not clear, the wind power project and power project approval out of touch, and Jiuquan wind power base of 10 million kilowatts publicly named.

Offshore wind power: “those who catch the wind,” the dangerous game

admin — Fri, 25 Jun 2010 10:18:46 +0000

Once a raging fire, wind power on land, although still facing difficulties such as grid, but with the last partition key benchmark price implementation of the policy has been somewhat a foregone conclusion.

The crowd’s attention has turned to a new layout of a wind energy resources. This time is long coastline on the southeastern coast, where the same rich wind energy resources, and inline the Yangtze River Delta, Pearl River Delta hinterland of the two electric power load centers.

National Energy Board recently launched the first round of offshore wind power domestic franchise tender, First Sound is undoubtedly the starting gun. Huaneng, China Guangdong Nuclear, Shenhua and other large power giants have bought tender documents, and local governments, small equipment manufacturers, supporting business and so the market stakeholders are actively awarded by them.

In the electricity price, interest return, wind turbines industry standards, etc. factors are not clear before, catch the wind by the sea has come.

Multiple competing interests

“These two, are we.” In a country wind turbine generator has undertaken preliminary work or the proposed offshore wind power project list, the Long Island county party secretary Jiang Qingchun finger to draw the two counties on Long Island offshore wind power project, told reporters.

Long Island County, two projects, a preliminary work has been completed, planning capacity of 4.8 million kilowatts, the other is still planning, planning capacity of 1.5 million kilowatts. One of this project, Shandong Province alone accounts for “12 5″ installed capacity of 3,000,000 kilowatts before planning half.

In addition, Shandong Province, other provinces have also wind generators been reported in coastal sea wind power installed capacity planning, Shanghai 700,000 kilowatts, respectively, 4.6 million kilowatts of Jiangsu, Zhejiang, Fujian, 1.5 million kilowatts and 400,000 kilowatts. However, early planning around the introduction of offshore wind power until the power companies actually have basically completed the layout along the coast.

This can push the project planning, “Last year (offshore wind) has more than 100 million kilowatts, the project not yet approved the start installed.” China Renewable Energy Association, said Commission Vice Chairman Shi Pengfei.

Occupying Power giant behind the sea coast of naturally active support of local governments, for face to keep GDP growth and structural transformation of local government pressure for offshore wind power to push through the wind supporting the local manufacturing industry has become the consensus.

A typical phenomenon is that in all coastal cities with high-quality wind energy resources, “Wind Power Equipment Industry Park”, is now blossom everywhere. small wind turbines Jiangsu Yancheng, for example, one divided into four functional areas of wind power equipment industry is stepping up construction of park, 1.5 MW and 3 MW wind turbine assembly line have been put into operation, the output value is expected to achieve 20 billion yuan.

This is a return to wind energy resources of wind power equipment manufacturing industry game between government and enterprises, involving the interests of the whole industrial chain of distribution. Unlike the economic return in the foreseeable future offshore wind farm, wind power equipment manufacturing industry is not to enjoy preferential policies, but can actually contribute to tax revenue and stimulating employment.

This is different from local government officials such as Jiang Qingchun most want to see. The offshore wind power project of the first round of concession bidding, in fact, is what took the “bundling” tender, about to project developers, wind power equipment manufacturers and professional installation company’s three joint tender.

“Local government resources through the advantages of wind power companies to attract – the power companies and as equipment manufacturers buyers be forced settled – and then led a series of manufacturers supporting small and medium service providers,” the interests of the chain, appear to be various stakeholders to achieve win-win approach.

But Jiang Qingchun, still has concerns, “the final right of approval in the National Development and Reform Commission, where we have no voice, or local government.”

In many local governments view, may be charged directly to the wind energy business resource tax is a better way. In this regard, has participated in the compilation of “renewable energy law,” the NPC Environmental and Resources Protection Committee, the former chairman Mao Rubai response to the reporter: “The State is aware of these situations from the local government is studying measures of.”

As for the wind power manufacturing company, this “bundling settled,” certainly means business for the market share of duplication, as well as the size of competing interests among manufacturers. It is estimated that at least fan device 30% of new capacity are such “bundling investment.”:wind power-wind energy-wind turbines-wind turbines-wind generators-wind energy turbines-wind turbine generator-China wind power

Equipment manufacturing industry in the face of fans may be the possibility of excessive competition, Shi Pengfei is not overly concerned about that, “to encourage manufacturers, Denmark 20 years ago, more than 20 manufacturers, the last only one and a half, and one is Davis Freitas, half home is Siemens. market proven ability to display the manufacturer must be through market competition. ”

In addition to wind power race between the interests of manufacturers outside the certified wind power equipment industry, cable and other facilities industry is rapidly active, increasing competition among the industry. A certified wind power equipment industry, told this reporter the past few years with the upsurge of wind power development, wind power equipment industry began to clear the development of certification, the industry is also the emergence of new competitors.

Model development path ahead

Offshore wind power involves a series of different elements of land-based wind power technology. National Energy Board and the World Bank produced a “large-scale offshore wind power and land-based wind power base in the challenge: Implementation Guide” on the offshore wind farm development, construction and installation overview of the technical elements. The first is for the offshore wind farm of fans and fan for the same land-based wind farms, but these must be the sea of fans, including consideration of infrastructure, where the water depth and seabed conditions, and future maintenance of the situation.

And domestic current situation is that a lot of offshore wind power projects are not upgraded or modified, put the unit of wind power facilities on land and sea wind direct transplantation, ignored because of the different regional environment, offshore wind turbines and blades, gear boxes, transformers and other equipment requirements and land-based wind turbine will also have differences between. Such as offshore wind generator system to run the reliability requirements of higher unit capacity greater than the land, the relevant unit equipment must meet the anti-typhoon, anti-corrosion and other special requirements.

“The wind wheel diameter, not rated power, is the most critical technical parameters. But have to see the next 20 years running, is not only to size.” Shi Pengfei said.

This “20 years of operation” involving the offshore wind farm is an important measure – availability. Onshore wind farms because of high availability only through some regular maintenance can be achieved. However, because relatively inaccessible sea fans, plus complex sea climate, offshore wind development in the early investigation, later maintenance also require substantial research and development resources as well as through practical experience.

“Offshore wind power has just started, and now the high cost, low power equipment, construction and lack of experience, related industry management and inadequate specification, immediately unrealistic large-scale development.” Recent meeting in 2010, Shanghai Guoji offshore wind TV 会上, National Development and NDRC Energy Bureau of new energy and renewable energy sources such Secretary Wang Jun had said. To sum up, placed in front of China’s offshore wind power development is undoubtedly the most important problem is, first, technology second is experience.

Beijing Jiaotong University Research Institute of New Energy Jiang Jiuchun has commented on offshore wind power technology in China: “We are still a mainstream product of wind power is mainly the introduction and imitation.” Industrial development is too rapid, long-term basis for the past R & D investment is not enough makes the development of basic research could not keep up, is a major cause.

“Including wind power is limited, it is not just power and fan issues, is an integrated aspect of the problem.”

Jiang Jiuchun that domestic offshore wind power development is most lacking, above all, we have not yet formed a complete solution including optimization of offshore wind turbine design to reduce wind turbine costs, etc. lifting. In addition, the wind turbine components and construction of facilities in key technologies, in particular, is one of the machine controller, is also lacking in our country. Most rely on imported, leading to domestic control the whole machine is very difficult, “This is a system problem, not a straightforward single set of problems.” Jiangjiu Chun said.

At present, Denmark and the UK offshore wind power project, the 5-megawatt fans have become more mature choice. China only Sinovel gold wind technology and a few other fan equipment companies have the capacity to produce 3 MW model. Hua Rui independent research and development of 5 MW wind turbine, it has only just completed the design and parts procurement, prototype has not yet off the assembly line, not to mention the actual operating experience.

The operating experience is exactly the same lack of offshore wind power development in the. China’s unique marine environment and climate, determine that originated in Europe, offshore wind power technology and experience, can not suddenly fit together with the actual situation in China together. , “At present, China wind turbines in use, accounting for 38.4% foreign capital, domestic capital and joint venture accounting for 61.6%, according to European standards vast majority of fan design.” Solar wind CMA assessment center researchers Xiuzhi said.

However, European standards are not considered tropical cyclone. Southeast coast of China just may be very frequent tropical cyclones, tropical cyclones and typhoons due to inclement weather so that China’s offshore wind turbines face a more severe test. A typical example is the 2006 typhoon “Saomai” landfall, the typhoon center hit Cangnan positive wind, leading to 28 Typhoon aircraft down 20 units, on the wind farm almost a devastating blow.

So, for the development of China’s offshore wind farm, the one is an urgent need to strengthen wind and other weather pre-survey and data collection, on the other hand there is also an urgent need for more demonstration projects to gain practical experience in.

“In the domestic small-scale pilot demonstration projects is a reasonable choice.” National Development and Reform Commission, said Li Junfeng, deputy director of the Energy Research Institute. On June 8 has just finished debugging, and put into operation all the grid in Shanghai East Sea Bridge project is the first demonstration projects in China.

Although the Donghai Bridge project was considered more symbolic than meaningful business model, but as the first “test the water” and “Network”, the Donghai Bridge project lessons learned during the installation, as well as offshore wind power project’s actual impact on the environment, There is no doubt all our offshore wind power development will gain valuable experience.
