‘Beware of overheating investment in wind power turbines equipment industry! “National Energy Board new and renewable energy Shi Lishan, deputy director of the first warning.

Subsequently, the state departments issued a document also pointed out that wind power equipment to strictly control the blind expansion of production capacity, but it was too late, has launched a large number of projects can not stop now.

Blind expansion led to excess capacity, excess capacity led to price wars, intensified the price war for some companies to reduce costs while ignoring product quality, the result is more than a year in the short period of time saw a number of fans and even off-grid collapse.

Conversely, frequent accidents caused by wind power the state to strengthen the regulation of wind power, wind power equipment market needs a substantial decline at the same time, its product quality standards are more stringent, and coupled with wind power equipment industry for the removal of subsidies , and let the wind power equipment industry is worse. We can say that wind power industry through the “Great Leap Forward”, the industry is currently in the depth of winter.

Of course, that wind power “Great Leap Forward” refers to its rapid development, resulting in not only on the number of quality, efficiency is not high frequency of accidents, not to say that China wind turbine generaotor does not need wind electricity. In contrast, although China has abundant wind energy resources, but the utilization rate is unusually low. Public data shows that China’s wind power installed capacity in India is only 3 / 4, Germany 1 / 4. No doubt, to develop wind power is still the state established goals and direction.

2012, when the “second five” first year, according to the 2015 and 2020, the size of China’s wind power capacity was 100 million kilowatts and 180 million kilowatts.

The NEA issued the first tender call in May. This invited bids to develop four pilot projects totalling 1 GW in Jiangsu, with the results due to be announced in September. Two of the projects, Dafeng and Dongtai, are inter-tidal. Both will be 200 MW in capacity. The other two, Binhai and Sheyang, classified as fully offshore, will be 300 MW each.

Representing an expected investment of CNY20 billion and with expectations high that a further tender for another 5 GW is likely to be issued within the next few years, there has been a flurry of interest and activity from developers and equipment suppliers alike. China’s leading wind turbine generator developer, China Longyuan Power Group, is one of the known bidders in the 1 GW tender, while other domestic giants like Guangdong and China Power Investment Corporation are also expected to be contenders.

Longyuan has also set up an offshore wind turbines manufacturing 50:50 joint venture (JV) in Nantong City, Jiangsu, in partnership with Zhenhua Heavy Industry Company. The new venture, called Jiangsu Longyuan Zhenhua Marine Engineering Company, will focus on the manufacturing of small wind turbines and installation of steel structures, while also offering full construction, installation and maintenance services for offshore wind farms, including the provision of foundation systems and subsea cables.

Wind energy in Britain already employs more than 10,000 people full time, and lobby group RenewablesUK expects that to rise to 90,000 over the next 10 years.

“We are very pleased that another significant milestone in the project has been achieved, and we look forward to discussing plans further with the wind turbine generator local community during the consultation process,” said Siemens project manager Dan McGrail.

Renewable energy offers significant potential job growth for Britain over the coming decades, with wind and other renewables such as marine energy providing numerous direct jobs, along with even more supporting workers in the supply chain.

The Carbon Trust, an independent government-backed advisory group, said that wave energy had the potential to add 16,000 direct industry jobs by 2040.

Manufacturers are increasingly targeting Britain as the UK government earmarks millions of pounds for adapting Britain’s ports for renewable energy infrastructure.

On the other hand, Germany’s onshore wind power market is still facing a new round of growth, the focus is not only the development of new small wind turbines farm, but the replacement (repowering) over or near existing operating life (15 years -20 years) old-fashioned fan. To encourage fan replacement, the German government in 2009, “German Renewable Energy Act” (German Renewable Energies Act) was amended, operators get 0.5 euro cents per kilowatt-hour replacement incentive. This is limited to land development and utilization in the case, by updating the existing fan to produce more electricity.

According to the German Wind Energy Institute (German Wind Energy Institute) statistics, in 2010 Germany had a total of 56 116 MW of wind turbines were removed, replaced by a total of 80 183 megawatts of new generating units. Replacement in the next few years will continue to increase. Currently, most wind turbine manufacturers in Germany for the onshore wind power development to a minimum 1.5-megawatt wind turbine, the largest up to 3.5 MW.
This wind turbine manufacturers is a huge opportunity. However, the “New Century” with Germany in exchange of some of the industry, the majority of people of Chinese wind turbine manufacturers entering the field are not good.

German Federal Department of Trade and Investment Renewable Energy Resources Project Manager with good Corti Anne Broughton Farm (Anne Bräutigam) that the German onshore wind power market has been very mature, operators and manufacturers have also established close co-operation and marketing relationships. The key is, as banks in providing loans to developers, requiring the developer to choose through the certification authority and have a good track record of running the (tracking record) manufacturers, and the Chinese wind turbine manufacturers lack adequate qualifications and certification to run record, it is difficult to be recognized.

Many people like to use Chinese enterprises in the export of solar photovoltaic panels to do the comparison, that the Chinese fans will follow suit – China’s current exports of solar photovoltaic products, international markets accounted for 70% to 80%. In this regard, the German Wind Energy Association’s “New Energy” magazine editor Hanna Mei pointed out that solar and home wind turbines market is completely different, the two can not be a simple analogy.

It is understood that the introduction of clear and bright sharp wind Nanxi Hydropower Co., Ltd. Zhejiang Jinyun to develop, for South Stream Hydro specifically incorporated in the Pan Zhe Jiang Dingfeng Wind Power Investment and Development Co., Ltd.. Project main construction content for the primary unit capacity of 1500 kW wind turbine 28, with a total installed capacity of 42,000 kilowatts, supporting a 110 kV step-up substation, access to 110 kV overhead lines, the central control room and auxiliary equipment auxiliary production and living space, inside roads. The project not only to fill the gaps in our county wind power, is the rise of eco-county road and adhere to the successful practice of the county to alleviate the energy shortage situation, improve the network structure, reducing environmental pollution, and promote local economic development is important.

Jinyun South Stream Hydro Ltd. is a private enterprise, specializing in green renewable energy development and investment, the project has put into operation a smooth power stations Jingning County, Zhejiang, Jiangxi Province, Sanjiang Zixi County power plant, Qingyuan County, home wind generator Zhejiang Longjing power stations, Zhejiang Jinyun County, South Stream power plants, total installed capacity of four power plants of 5.7 million kilowatts, the average generating capacity of nearly three years, 200 million kwh. Up to now, the company has invested 600 million yuan tourism development projects and electricity.

Support wind power is the country’s new energy industry, specific to the project, the site can be described as very superior: first, the town of Incheon sharp roll-Tao Ching Ming steep mountain village steeper, the peak average elevation of over 1,100 meters, wind higher power density, weather experts initially estimated the average annual wind speed of the lot up to 6.5 m / s or more; Second, the terrain of the lot is better, can take full advantage of the mountain, without loss of arable farmland, traffic and transportation can make use of Village Road, Road reconstruction of forest fire prevention, conditions are more convenient; Third, the line access port near the cold water from the nearest 110 kV substation is only 20 km. Because there are so favorable conditions, hydroelectric companies in the coastal South Stream, Dongtou, Xiangshan, Cangnan, Pan, etc. for wind turbine generator multiple visits and field research, the final site in the town of Incheon sharp roll-Tao Ching Ming Village area.

It is understood that the system put into operation last month, since the transmission grid has about 300 kilowatt hours of clean electricity, the average daily windmill generator power output of 6 kwh.

“The wind blow, sun drying, the family’s power consumption will not have to worry.” Mr. Du said, with wind or solar power alone, will be affected by seasonal and weather factors, and the wind and a good solution to this the problem.

Internet to sell excess electricity to power company

Yinzhou District Power Supply Bureau, the official said, wind, solar and other new energy generation there is often a case of voltage instability, more difficult access to the grid, while the smart grid is a good solution and network security and technical issues critical to ensure family continuity and reliability of supply. For example, due to the higher voltage required for starting air, so when start the air conditioner, the smart grid will automatically switch to the grid, using grid electricity; when the air is stable, the smart grid will automatically switch back to using solar energy, wind energy the electricity. If there is surplus electricity sent, two-way smart meters can also be uploaded to the grid and sell power company.

Costs are high, there are still difficulties to enter the family

“Small Wind power  generators now costs still relatively high, into the family very difficult.” Mr. Du also admitted that the current small-scale wind and solar for power generation is still in the experimental stage, the purpose of the equipment to do is to test the technology of distributed power is mature, smart grid and grid test the feasibility. Results show that there is no problem.

It is understood that the promotion of new energy at home and abroad often take subsidies. But for small wind turbines and small wind and solar power generation, the country has not subsidized. “However, as technology development, product upgrades of equipment and materials to reduce the cost of ordinary people at home fitted with a small wind and solar power generation system is not a dream.” Yinzhou Power Supply Bureau, a source said.

Wind power cooperative ownership structure of industry

Danish wind farm is unique in its ownership structure of the collectivization, ordinary people can be added to the Government’s strong support for wind power projects, wind farm shares a shareholder holding of local residents by the way, a good solution local residents due to wind noise 、 destruction of landscape and other negative factors arising from the resistance.

Copenhagen Business School professor Peter • Ka Yueer that the cooperative form of ownership is a long tradition in Denmark, the Danish bank 、 dairies and slaughterhouses and other industries have a wealth of operational experience, onshore wind farm in the 1970s began to Using this form of operation for those who have backyard wind turbine residents, the windmill turning at the same time, a steady stream of money flowing into their bank accounts.

Middelgrunden is Denmark’s first cooperative ownership structure approach to offshore wind farm operation, located in Copenhagen, East Coast, formed by the 20 windmills on the Taiwan Strait. The wind farm began operating in 2000, the total investment amount of about 48 million euros available 8856 shareholders, their shares can be traded freely.

Middelgrunden wind power cooperative board member Hans • Christian • Selun Sen is an engineer, working for sustainable energy industry, told Xinhua News Agency reporters: “Denmark, the use of cooperative ownership structure model, is to make more people to participate in the wind them to power plan, which not only make people more receptive to wind power projects, while avoiding the local residents reject wind power project. ”

Cooperation with Middelgrunden wind farm ownership structure of this idea was first proposed in 1993, after local residents and non-governmental organizations, reached after consultation. Selun Sen said: “You pay DKK 4250 (1 U.S. dollar equals 5.5 Danish kroner) to purchase a share, and then return 600 Danish kroner per year, which means that the initial return on investment of 14% to 15% since then yield will be slightly lower, but the full cost recoverable after more than a decade, but also get 7% The annual rate of return. people are very satisfied with this result, because the money in the bank than the higher income also contributed to environmental protection. “

The wind turbines wind farm for the plateau tailored to overcome the high altitude high altitude, wind conditions, complex, varied terrain, air density and low adverse factors, the wind turbine has been optimized with a large number of special design. The unit uses a new protection system, to enhance the fan’s anti-UV, anti-icing capabilities; design a new cooling fan cooling system and lightning protection systems; to maintain superior low voltage across the function, control and electrical performance, fully meet the power of machine requirements.

“CSR Zhuzhou are” into the wind power market has been five years, currently has 1.5 MW of high-altitude wind turbine, a full range of 1.65 MW wind turbine, 2.5 MW coastal / inland wind turbine and other products, from Northeast and saline intertidal wind farms, to negative Northwest wind 30 ℃ low temperature, electric field to the mountains of southern China, to Yunnan, Guizhou, Tibet’s high altitude wind power generation, the company that makes wind generators, wind farms are able to adapt to differ
