"Wind power" rapid expansion of the national goal two years ahead of schedule

In the tight global energy and energy-saving double the weight reduction, new and renewable wind energy sources by the great favor. Relatively high price of solar power generation and has been close to full capacity of the hydropower resources of wind power (hereinafter referred to as "wind") has become the most popular these days of "Beloved."

In recent years, wind power more like a continuous "Tornado", from the southeast coast to the north of the vast inland, a block from where they stand wind power, wind power in recent years has become the most rapidly developing renewable Energy, from the beginning, "added energy" toward "alternative energy strategy" direction.

However, this kind of "blowout" behind the development of the wind power industry has gradually become hidden worries. "Large state-owned developers and local governments just want to increase the installed capacity of wind power, wind did not consider the adequacy of resources. Wind power market development is a major driving force behind the political will and policy of mandatory market share, but it ignores the power generation." China Wind Energy Association to the Secretary-General Qin Haiyan, "China Economic Weekly" said that while at the same wind machine manufacturing market, has just made a difficult start to move. Wind developers and the province of TV appearances frequently "from China's wind power development in the situation, in the first half of this year, the installed capacity of wind power has more than 6,000,000 kilowatts, the state proposed by the 2010 completion of the wind power goal at the end of this year will be able to achieve . "Qin Haiyan a few days ago to the" China Economic Weekly ", said. In fact, in recent years, wind power development all the way "full speed", in particular, in 2006 the implementation of "renewable energy" after two years in a row the growth rate of more than 100%. In 2007 a total installed capacity of wind power in China is about 5,900,000 kilowatts, is the 2006 total of 2,600,000 kilowatt installed capacity of more than twice as much. Only to the United States, Spain, the world's fastest-growing wind power market, the scale of wind power has the fifth highest in the world.

In March this year, the National Development and Reform Commission issued the "renewable energy development" 11th Five-Year Plan "," will be installed capacity of wind power in 2010 as the target of 10,000,000 kilowatts, will be installed capacity of nuclear power plan 1 / 2.

China Wind Energy Association show that as of the end of 2007, the country has built more than 100 wind power, are located in 22 provinces (autonomous regions), the previous year in 16 provinces on the basis of an increase of Henan, Hubei And Hunan provinces, and there have been some new wind and the province of large developers.

In these 22 provinces, major wind power is still concentrated in the resource-rich "Three North" areas and coastal and beach areas, in particular the planning of giant 1,000,000 kilowatts of wind power or wind power base in several provinces such as Inner Mongolia, Jilin , Gansu, Xinjiang, Jiangsu, Inner Mongolia, which became the first of more than 1,000,000 kilowatt installed capacity of provinces, and Gansu Jiuquan of wind power projects as the "Land of the Three Gorges", 10 years is expected to become the largest wind power industry with.

By the end of September 2007, the completion of the Longyuan Wind Power Corporation 1,005,000 kilowatt installed capacity, China has become the first breakthrough 1,000,000 kilowatts of wind power developers with Guohua Electric Power, Datang wind power, Huaneng New Energy Corporation and a number of environmental protection Large state-owned power developers together to lead the development of wind power.

China's wind energy development on the sea late, but has also been started. Qin Haiyan told the "China Economic Weekly", in 2007 in the vicinity of Shanghai in the East China Sea Bridge offshore wind power project to complete the tender and started the preparatory work. Although China's development of wind power at sea, including equipment manufacturing, installation and maintenance to run no experience, but in the East China Sea Bridge offshore wind power projects such as wind power project start-up, marking the official start of China's wind power at sea. Wind power is expected to become China's second largest power in December 2007, the state department's third wind energy resource survey results show that our country can develop the land for 6 to 1,000,000,000 kilowatt wind power; marine resources, wind energy has not carried out detailed Census, according to preliminary estimates will reach 1 to 200,000,000 kilowatt of installed capacity.

On the whole, China's land-based wind energy can be developed on the sea total of about 7 to 12 million kilowatts great potential, wind energy has become an important part of the structure of the resource base.

Qin Haiyan, said that if uphold and improve the active support of wind power, steadily enhance the production capacity of wind power equipment and technical quality standards, China is expected over the next few years will continue to maintain annual capacity of 4,000,000 kilowatts of new growth in 2010 Can achieve a total wind power installed capacity of 1400 to 15,000,000 kilowatts; if in 2010 after an annual increase of 700 to 8,000,000 kilowatts, to meet the existing standard in Europe, then in 2020 a conservative estimate of wind power can achieve the 8-10000000 kilowatt installed Machine.

In 2020, China's wind power could become the third largest nuclear power than the main power supply in 2050 is likely to exceed even water and electricity as the second main power supply. At that time, wind power generation in the future may become one of the main energy strategy. At present, on a global scale to Europe and the United States and other developed countries represented, the world's wind power has emerged a large-scale development. New installed capacity of wind power, in recent years has also become second only to new natural gas power generation, the second largest installed capacity of the new power.

In 2007, when the world's new wind power installed capacity of 20,070,000 kilowatts, mainly in the United States, Spain, China and other countries. In 2006, wind power for the European Union provided 3.5 percent of the electricity. Spain which more than 6%, more than 7% Germany, Denmark more than 20% of the electricity supply from wind power.

This shows that wind power has been from the beginning, "added energy" in the direction of "alternative energy strategy," the direction of development of the world's recognized, the closest to commercialization, the market's most competitive renewable energy technologies.

The more people believe that wind power is the "golden age." To show rapid expansion of the "hidden worry", "good news" behind the development, some experts have begun to "worrying."

The rapid expansion of wind power's "Great Leap Forward", the activation of a large wind power equipment market. According to incomplete statistics, China's wind power unit machine has 50 manufacturing enterprises, 10 enterprises of the prototype off the assembly line and run the installation of wind power.

Qin Haiyan to the "China Economic Weekly" said that by 2004, only 6 of China's Family Style electric machine manufacturing enterprises, in 2004, almost all domestic manufacturing enterprises in the field of large-scale heavy industry, including aviation, aerospace, shipbuilding, power station equipment Manufacturing, transmission and distribution equipment business in a huge wind power market to attract the next one after another into the development of wind power unit.

It is reported that Vestas (Vestas) and a number of foreign countries of the world's leading wind turbine manufacturers, but also active in the establishment of Chinese manufacturers. At the same time, with the machine manufacturers of the rapid development of domestic wind power emerged in a number of parts and components manufacturing enterprises, China's wind power equipment manufacturing industry developed rapidly.

However, a large number of megawatts of new wind power unit-level product in a hurry to run into large-scale production, quality and reliability problems run even become a wind power generating capacity can not be achieved one of the main reasons, an increase of technical and economic risks. China Wind Energy Association survey found that the machine manufacturing enterprises in operation are in the process of trial and there were quality problems, but also to pay a big price.

An expert told the "China Economic Weekly", in Inner Mongolia last year, an installed capacity of wind power, because only a small issue, commissioning a year, and the main reason for this is that most of the installed capacity of wind power in accordance with the standards of the European Climate Design is not necessarily suited to China's climate.

By the end of 2005, according to statistics, the installed capacity of wind power (1,260,000 kilowatts), at least 25,000 kilowatt generating units because of quality problems at one time issued no electricity, there are a considerable number of other units as a result of quality problems can not be achieved power generation , And earnestly solve the energy problems of the environment, far from the goal line.

Qin Haiyan told the "China Economic Weekly," As China's installed capacity of wind power continues to increase rapidly, these problems are not solved as soon as possible, and could pose a major risk in the next few years focused on the outbreak of serious harm to our country is bound to wind power equipment Long-term development of the manufacturing sector and a large number of stable operation of wind power. Core technology industry constraints, "self-development" At present, China's wind power equipment manufacturing investment and production structures are very uneven, and many domestic enterprises Yiyongershang into the wind power industry and focus on the development machine, and gearbox parts and components supporting the development of R & D investment And the production capacity is obviously insufficient, leading to uncoordinated upstream and downstream industries. In addition, electronic control systems and key parts such as bearings is still dependent on imports.

In the past two years as the world's wind power equipment, parts and components supply the growing tension, a lot of machine manufacturers in the international market by the shortage of key parts and components procurement cycle as long as 18 months, has been ordered into the contract in 2009.

Double loop, Shanxi Heavy Machinery Co., Ltd. is responsible for the relevant told the "China Economic Weekly", as the national speed the expansion of wind power projects, they produce the flange (wind power related accessories) has been in short supply, the supply contract to 2009 has been fixed. Recently they prepared to launch a new equipment to expand production capacity.

"Rapidly growing industry, subject to increase the capacity of core technology." Qin Haiyan pointed out that China's wind power equipment manufacturing industry is still in the "technology digestion and absorption" to "independent innovation" in the early stages. The level of core technology and independent innovation capability is still relatively low, constraining China's wind power industry of their own development. At the same time, between upstream and downstream industry chain, qualified and reliable supply of key parts and components production capacity is relatively low, and our country in the near future (2010) to form an effective megawatt-class advanced wind turbine capacity constraints pose obvious.

Qin Haiyan, said that although China's wind power has developed rapidly, and foreign markets mature, advanced technology is still a considerable gap, compared to thermal power equipment, such as the law of mature development of the manufacturing industry, China's wind energy industry is still in growth The initial stage of the majority of key technology companies is still in the digestion and absorption of sound stage or on the basis of which to carry out the innovation process will take some time accumulation. At present, the rapid expansion of the market, increasing competition accumulation of large enterprises are facing pressure to survive. The central government subsidies depends on the "certification" for China's wind power is currently the status quo, industry experts have long called for the introduction of product certification system for wind power in order to improve China's wind power equipment manufacturing and development capabilities to ensure product quality, promotion of such equipment in China And technological progress, wind power market, reduced investment costs in order to effectively promote the wind power industry's healthy development.

August 22, 2008, the Ministry of Finance announced the implementation of the "wind power equipment industry Interim Measures for the Administration of special funds" (hereinafter referred to as the "Rules"), "Yijiangdaibu" to support the industrialization of wind power equipment.

"": With the support of business conditions in the first 50-megawatt-class wind power unit, by 600 yuan / kilowatt standards be supplemented. The machine manufacturing enterprises and key parts and components manufacturing enterprises 50%, and to focus on key parts of the weak links in favor, and grant funding for research and development of new products.

However, the requirements "to apply for grants of wind power unit must be certified products", and has production in the first 50 Typhoon aircraft "sales, installation, commissioning and network and power generation", that is to go through the industrialization of the results of market testing.

Ministry of Finance said the move is in support of wind power equipment, key technology research and development, to accelerate the development of wind power industry.

This is the first time the central government on renewable energy products for cash grants, but also in China for the first time the results of product certification as a government cash grant of the necessary conditions.

The industry said that the use of wind power product certification and the results given cash grants, will go a long way to promote wind power equipment manufacturing enterprises for the introduction of technology digestion and absorption as well as the ability of independent innovation and enhance the importance of product quality, speed up China's wind power equipment manufacturing Industry, technological progress, with the core technology of cultivating its own brand of intellectual property rights, have a significant role in promoting.

Qin Haiyan that, at present, the wind resources in the country has been fully detailed investigation, which will in the future development of wind power to provide a more detailed and accurate data. At the same time, has been carried out by the wind turbine product certification results, certified wind power unit and reliable quality, good performance, operation stability, the industry has become concerned about "a model project."
