10 八 10 Competition for wind power equipment company
Currently the price of wind power generators equipment close to the bottom line, and then decline is likely to harm the normal development of the industry. The existence of domestic wind power equipment “heavy weight quality not quantity”, “vicious low bid” and cause for concern, because of wind farm equipment, quality problems affecting the normal operation of the examples also abound, so, wind turbine generator procurement of equipment market investors should not only look at the price the quality is not important.
In addition to scaling, compression management costs and other traditional ways to reduce costs, Bao Zheng margin Zengchang the same time, Bushao home wind generator equipment business in the sights with Gao gross margin is expected of offshore wind power market.
Compared to onshore vertical wind turbines equipment market, fierce competition, offshore wind power to higher barriers to entry, while the higher electricity price, it can tolerate higher equipment costs, therefore, market access are expected to be in the first period of time than high gross margins. This consensus has led to land-based wind power equipment manufacturers Xiaojiannaodai into offshore wind power, “Arena.”
Foreign-funded enterprises also “snatch”
International manufacturing giants fan is also attached great importance to the Chinese market, have set the layout. Vestas said the fans in China this year, 3.0 billion investment in manufacturing, the V60-850 千瓦 Fan is defined as “a specifically tailored for the Chinese market fan.” Years, China will set up offshore wind power business office. May 22, 2009, Siemens wind turbine blades (Shanghai) Co., Ltd. to enter the Chinese high-profile offshore wind power market, the investment reached 581 million yuan.
Wind eletric generators equipment industry has entered a phase of strong competition, no rate of domestic companies or foreign companies want a slice, hard to fall in., wind power equipment industry with a crazy word to describe it is not surprising that this times when the end of the madness in the end, depending on the industry’s good luck.

04 八 10 U.S. wind power noise complaint
Oregon Ione (IONE) hilly areas have recently welcomed their uninvited guests – to generate renewable energy wind turbines.
Caithness Energy (Caithness Energy) is making this area which became the fastest growing wind power one of the regions. Company representatives in the local Kaitelixia? Peel (Patricia Pilz) to the residents out an attractive conditions: the signing of a waiver, no longer complaining about wind turbine noise, you can receive 5000 U.S. dollars check. (1 U.S. dollar equals 6.78 yuan)
84-year-old local farmer Qiaozhigeli Griffith (George Griffith), said: “We can call it closure fee? This money as if the ill-gotten gains so easy.” Griffith happily accepted the check, But not everyone wants the money. Steady decline in the economic crisis in the area of rural economy to worsen, it has long supported hydropower, Oregon has developed millions of dollars in tax incentives to promote local renewable energy development. But even so, turbines or incurred by the people’s protest.
Some local residents and has been established to run the wind turbine contradictions. Empty valley between the mountain wind whistled often allow people to yell to hear each other, but residents still complain about wind turbines made too much noise.
Turbine opponents Mike Eaton (Mike Eaton) said: “The only thing we can rely on only the noise regulations in Oregon.” Oregon is a special legislative restrictions on http://www.allwindenergy.com/ noise in the world. Pursuant to state law, wind turbine noise, the noise level can exceed the number of the local environment, but sometimes the definition of environmental noise levels there is a dispute, the measuring method and location have not reached a consensus.
Although the legal limit of wind turbine noise, but as early as the first wind power project in Oregon before becoming responsible for the implementation of industrial noise law of government agencies have been disbanded in 1991. The agency under the State Environmental Quality Board, the council spokesman William Knight (William Knight) said that although the regulations registered, the relevant entities should comply with, but this environmental quality department is in limbo.
This year in May, experts from the acoustics get personal testimony, the Morrow County Planning Board agreed to Maike Yi accused of sexual and other opponents of the complaint, determine the Eaton family behind the wind turbine does exceed the allowable noise levels. Commission ordering operator Invenergy company achieve compliance requirements within six months.
But this has not died down, Invenergy company quickly filed an appeal, Eaton and its allies as well, Morrow County Council also requested the Board to clarify its decision. McLean County Planning Commission Director, Carla (Carla McLane), said: “Both sides appeal the same problem. ‘Disobedience’ mean? In the end of 6 months to comply with any rules?”
Opponents said the small wind turbines hissing sound made them feel anxious, low-frequency vibration is often awakened at night people. What is more, said the noise so that they nausea and headache. But some residents said that almost did not hear the noise. Turbine noise hazards controversial.
Critics say opponents is actually unable to lease their land to wind developers angry. Some opponents said that if Invenergy company to shut down some turbines at night, they will be satisfied. While others said they lost their idyllic life, hope for compensation.
Local wind farm has 48 turbines, is now running more than 18 months, Invenergy company is still dealing with the noise problem. Caithness Energy companies want to pre-settlement and asked for some residents to sign a waiver allowing the noise beyond a certain level. Caithness Energy plans to build more in the electric field near the “flat shepherd” Wind wind farm. New power plants are expected to install 338 wind turbines, installed capacity of more than 900 megawatts, will be completed in 2013, when would be the one of the largest wind farm.
“Shepherd the ground” and will accept the Government’s management of large-scale farms. Siting of energy facilities in Oregon Secretary of the Committee Toms Top (Tom Stoops) said that large-scale projects must ensure compliance with noise regulations and noise in the solution include waiver.
“New York Times” said that local representatives of companies in Caithness Kaitelixia Pierre did not provide the company’s contribution to the residents sign a waiver of the relevant information, but several owners said, Pierre is willing to provide them with 5000 U.S. dollars.
Some did not sign a waiver of the residents said, Peel said, “Shepherd flat” power plants will be difficult to make the local economy and benefit the U.S. energy goals, residents refused to sign the noise if the waiver is not considered a comprehensive approach.
33-year-old farmer Teng (Jarrod Ogden), said: “The lady (Pierre) to the time that other people have signed.” If “the shepherd flat” power plants completed, Ogden is home to Taiwan against several hundred meters wind turbines.
Ogden said: “But I know some people did not sign. I strongly support wind generators , but I will not let developers so buy me. I think they just want to buy a cheap guarantee Bale.

03 八 10 Opportunities in offshore wind power industry contains multiple challenges
This year in April, offshore wind power concession projects start, the National Energy Board to Liaoning, Shanghai, Shandong and Jiangsu provinces, 11 departments issued a circular calling for offshore wind power to declare parts of the concession tender, in accordance with the “first trial , after the expansion of “the principle of construction, according to wind energy resources, the marine environment, power and technical capabilities to send to determine overall size of the project.
Offshore wind power construction began striding speed overweight.
And Shanghai is one typical case, in July, China’s first offshore wind pilot project large – Shanghai East Sea Bridge and the 100 MW offshore wind farm grid of 34 wind turbines moving, very spectacular; At the same time, Shanghai Electric developed the first national sea fan off the assembly line of 3.6 MW, the wind wheel diameter of 116 m; as representatives of private enterprises in Shanghai million German wind power company, its two-megawatt permanent magnet direct drive blower Not long ago, also offshore wind farm in Fengxian grid. All these show that the Shanghai building offshore wind and marine equipment wind generator manufacturing is entering a fan of rapid development.
“In fact, China has rich wind power resources, these resources are hidden in the long coastline of gold. Also, offshore wind power not very occupied area, and near the load center, unlike land-based wind power with long-distance transport of trouble. “investment consultant in the energy sector, Qian Jiang, chief researcher told reporters.
The real world, though in recent years China has made rapid land-based wind power development capacity was double the growth for four consecutive years, but the development of offshore wind has just started. China 2009 new offshore wind power installed capacity of only 63,000 kilowatts, while offshore wind power over the same period of the fastest growing of the United Kingdom to achieve additional capacity 306,000 kilowatts, the cumulative installed capacity of 894,000 kilowatts.
The current national primary approach is through a competitive mechanism to promote offshore wind power turbines development. Just last month, the National Energy Board launched the first offshore wind power generator project concession tendering. Already basically decided to select two in Jiangsu coastal and two offshore wind power project wind power project beach, which a single item scale offshore wind power development of 300,000 kilowatts, beach development of 200 thousand kilowatts of wind power, Energy Bureau to prepare this 1 million kW four projects at the same time for bidding.
“Land-based wind power competition is fierce, but compared to the threshold of offshore wind power will be higher electricity price will be higher, and can withstand high equipment costs, so many land-based wind power equipment manufacturers are on the field ‘eyeing’ it is not hard to understand.

02 八 10 Prosperity and to promote energy storage technologies, wind power development
In recent years the rapid development of wind farms, but because of its poor reliability of power output and unpredictable, therefore, to ensure power supply stability and profits increased, electricity suppliers racing to develop energy storage technology.
Hawaii officials hope that by 2030, 70% of energy needs to provide the origin, while the state is facing the problem of wind power generation, mainly the power sector is not able to excess wind power generators output to close to the company, can not enter in the weak wind power. If the local Maui (Maui), total wind power capacity could reach the island, a quarter of the peak power, peak power and peak demand, but time is not the same, which brought to Hawaii to complete difficult goals.
“New York Times” said that the best option currently seems to use batteries. In New York and California, the power sector is to develop a power storage technology, even to “carry” the space, namely the use of such lower price to buy midnight hours of electricity sold at higher prices after a few hours . In the Midwest, public utilities shows another power storage technology, in a minute or less time may be repeated several times for the conversion charge and discharge, to help power against solar, wind generator and wave transmission failure. In Texas, power companies placed in different locations through a transmission line connection from the battery to stabilize voltage.
Many enterprises believe that the wind turbines industry, renewable energy goals can be achieved. Hawaiian Electric spokesman (Peter Rosegg) said that if the energy source is intermittent, “No battery will not achieve its objectives.” The company has agreed to from the island of Oahu (Oahu) north of the coast to buy a wind farm power. 30 MW installed capacity of power plants by the Xtreme Power Company to install a 15 MW battery.
Luo Saige said the power plants in Hawaii the best location of wind farms is one of its power supply volatility and lack stability. In addition, the power generation market is Honolulu on the island farthest from the company’s load center location, even from the company’s high-voltage transmission backbone.
Xtreme Power president Kaluosike (Carlos J. Coe) said, the computer will try to keep the battery in the day most of the time in the semi-charged state. If the wind suddenly increased or decreased, the battery current will be stable, so that power seems to gradually increase or decrease.
Hawaii’s success lies in its wind power generation facilities, the frequency adjustment function. AC system to run 60 cycles per second, while the battery can be carried out in 60 seconds from the charge to discharge or change in the opposite direction, so as to maintain frequency stability. Battery system can be used for profit, at the lower price store electricity, while the release of higher electricity prices. The battery can hold 10 MWh of electricity, equivalent to a 30-megawatt power plant produces 20-minute full-load power delivery, amazing storage capacity.
First Wind Company and Xtreme Power battery companies did not disclose the cost of the system, but public figures, the cost of the wind farm is about 130 million U.S. dollars, the battery system, which costs 10 million U.S. dollars, the U.S. Department of Energy provided 117 million U.S. dollars of loan guarantees. (1 U.S. dollar equals 6.78 yuan)
Power storage cost and value for consumers is difficult to predict. Off-peak electricity during the storage cost, and the highest cost of electricity is very expensive. “New York Times” said that if renewable energy sources to reduce dependence on coal and natural gas demand, which is an additional benefit.
Kaluosike estimate the efficiency of the battery system for more than 90%. If this figure is confirmed, the battery system is indeed a major step forward. Currently, the most efficient use of energy stored in the form of pumped storage power station comes as its efficiency of 70% to 85%.
Electricity sector also used to store electricity and other strategies for FM. Beacon Power is building a component from the 200 flywheel power storage libraries, storage grid electricity, and ensure accurate AC system in 60 cycles. The top of the flywheel is a generator or motor may be alternately used as a device that can store or access in the flywheel energy. U.S. Department of Energy cost of 69 million U.S. dollars for small wind turbines this project provided 43 million U.S. dollars of loan guarantees.
U.S. Department of Energy as the use of compressed air energy storage project to provide support. Surplus electricity to pump air into underground caves, when you need electricity, empty of air into the gas turbine generators.
