129779321215156250_0Five sharp loss in wind power brownouts in electric power Enterprise
March 29, Beijing Hilton Hotel in the Ballroom on the third floor, the second China International Summit of new grid-connected energy access is being held.
This large room is not filled with tables and chairs
tera power leveling, but even so, still the seat too much idle is to allow photographers to shoot a picture of reaction field-warm and worry about. Speak on stage, an expert in high spiritsRepeat the prospect of China's ambitious objectives for the development of wind power, wind power has the commercial prospects of the future; the audience a little Burnout, was readily through a catalogue, or open your mouth and make a big yawn deeply. Viewing from desktop to the audience, like the incredible years of the wind power industry--"chicken" after the best picture show. In 2011, the new wind power machine 16.501 millionWatts, added 18.92 million-kilowatt declined compared with last year, an increase is negative.
This means that, since 2005, wind power for 5 consecutive years the rising trend in this year began to turn.
This change, in fact only wind industry "fall into" another note. "In 2011, five electric power generation group, in addition to China, the State power of the windAdded outside the machine just dropped, growth in both the remaining three, released five major wind power group in the country increased by percentage of total per cent in 2010 to 58.2% last year.
"Huadian new energy company's chief engineer said Yuan Kaifeng. But rivals reduced, does not make it a few times better than some of the huge power generation group. Huadian new energyFor data display, when the 2010 National wind power generating capacity up to 50.1 billion-kilowatt, 81.41% per cent growth, 2011 when the wind power generating capacity is about 70.6 billion-kilowatt, an increase of only 40%, electricity growth fell sharply. More ugly is the equivalent of fan device utilization hours. "Five hours have seen negative growth of power generation group. In addition to DatangNew energy (01798. HK), basically reduced by around 200 hours.
"Yuan Kaifeng said. The end result, is wind power developer losses for the first time last year. All changes are associated with a Word, that is, "rationing". Although the power company has claimed to have made the greatest effort to ensure that the grid-connected wind power, but at least it appears effectiveFruit is still not notable.
When wind power field experience "into the back" post, wind power company and power company in "power rationing and desert wind" game, or will no longer be "stragglers and disbanded soldiers" and "regular army" of negotiations, but power big brothers and the network contest between big brothers. Five major wind power enterprises by substantial losses when the China Longyuan power 11 years (00916. HK), General Manager, thanksSummary of long arms they only do one thing--to create an industrial chain. "Dragon source is the management of the whole process, from early canonized, design consulting, procurement of equipment, operation monitoring, maintenance, technology research and development, or even the development of CDM, we are done.
"Xie Changjun told reporters. Kung Fu TSE is not in vain. China Longyuan power 2011 annual report, even in situations such asThis was last year, long Yuan continues to achieve new machine 2042 megawatts, 2.638 billion yuan in net profit. "Dragon source is good, but some companies there have been losses. "Yuan Kaifeng said," wind power ensure stable yields despite drought or excessive rain are gone, the operating conditions of the industry as a whole is becoming difficult. "Wind power profit for the power losses in the past filledConditions are different, according to a survey published by ITU in July last year, five power generation Group of wind power profit loss of $ 140 million, profit from the June $ 820 million reduction. "This July is indeed little wind related, but a loss is likely to be the industry trend, it is worth noting.
"Yuan Kaifeng said. Many owners feel financial pressure,"Prudent" for which monetary policy arising from the dramatic increase in financial expenses. Huadian new energy statistics, July 2011, five power Group's financial liabilities amounted to 2.4823 trillion yuan, an increase of 17.23%, the cumulative finance charges on electricity 52.832 billion yuan, an increase of 33%. "Conservatively estimated five power Group annual cumulativeGeneration of financial cost will exceed $ 100 billion. "Yuan Kaifeng said.
In such a context, for wind power project developers had to choose they can, make new wind power machine speed is constrained. In fact, wind power last year the entire industry chain is trying to find ways to lower the costs, wind machines, for example, the average price level has risen from $ 6,000 in 2008/KW down to last year's 3,400 Yuan/kWh.
This led, wind farm development costs are lower. "2009 average development of wind farm cost was $ 9,320/kWh, 2010 was $ 8,295/kW, last year, the price dropped to $ 7,900/kW.
"Xie Changjun, said. Falling equipment prices for developersNatural is good, but it is difficult to change the fact that many developers losses last year. Yuan Kaifeng are concerned that sharp price decline could cause problems of product quality and customer service. "Incomplete statistics, called fatal accident last year alone, more than 30, has sounded a warning to security issues.
"Great power and network game? "Restricting the development of wind power industryWhere are the biggest obstacles?
"Yuan Kaifeng in the eyes of the most important issues, most likely to give the same answer: the energy. In fact, even the best Dragon source, also suffered power cuts last year. Xie Changjun told this reporter that long source of equipment availability is an average of 97.78%, equipment utilization hours were 2,230 hours last year due to windSome effects of the decline in resources and power rationing, hours fell to 2026 hours. "Because of power cuts last year, Longyuan company lost about 100 hours number of hours, total amount of energy over a generating capacity of 10% per cent, reaching 30% in the eastern most region of Inner Mongolia, Heilongjiang, Jilin 20% reached. "Xie Changjun," said power cuts last year DragonSource has cost about $ 5 billion. "But even so, Longyuan is still the loss of small enterprises in the industry. "China electrical equipment to reduce the number of hours a 500 hour, up to 491 hours.
"Yuan Kaifeng admits. It is understood that the 2008 National wind power resulting from the power of about 296 million kWh of power network energy loss, 2011 power cuts for more than 15Billion kWh, about of the total wind power generating capacity of 12%.
Among them
tera gold, five power generation Group cumulative total abandoned to the desert wind wind is more than 90%. Often talked about here, Xie Changjun don't forget quipped, "I joking with power led, I said half the US $ 5 billion in losses last year to the power grid, power cuts might not. "In fact, for a long time, the power gridAre considered to lack of enthusiasm on the grid-connected renewable energy.
But Xie Changjun and Yuan Kaifeng did not forget to mention: power over the past year have made a lot of work.
According to data from national grid, 2011 State net cumulative power grid transmission lines built at 26,200 km, built wind power transmission substation, 25, 37.701 million VA transformer capacity. That is,So, because wind power base in Xinjiang, Inner Mongolia and Gansu local loads demand, cross-regional transmission is blocked as a result of power rationing is still obvious. "2010 State net positive to promote large-scale wind power transmission project and related transmission project across provinces and the preliminary work, Simon was completed to Hami, Nanjing and South to North to Chongqing, Zhengzhou, Hami, ultra high voltage output and research work,Look forward to the future, sending problem will be improved.
"Net the person responded that when interviewed by this reporter. But the question raised, cross-regional transmission problem has "Eleven-Five" on the premise of the agenda, has yet to be resolved is that advocated by the State network of AC UHV power grid is not the best wind power online. "Japan and the United States and other developed countriesHave abandoned the technology line, because AC UHV power grid connection, and is likely to have massive power outages, but transmission investment, loss, not economic.
"One industry source said. Yuan Kaifeng confirmed this view, for example, "measuring says sent to Jiangsu and Zhejiang West Inner Mongolia wind, electricity cost in 6-7, Jiangsu ProvinceConstruction of wind power projects, cost or 6-7/. "Smart power generation or as a breakthrough data analysis company's Power eTrack on 2010 United States, and Germany, China and India generating combinations of various ratios of the energy situation in doing a survey, results, 2010 total annual electricity production of 4373TWH in China, of which coal accounted for 78%Specific gravity, followed by hydropower for 15%, wind and nuclear power accounted for respectively 2%, oil and gas power generation accounted for 1%, power, geothermal power and biomass ratio of photovoltaic power generation is even smaller. By contrast, in 4 countries Germany generation combination of relatively balanced, of which coal accounted for more than 43%, nuclear power is 22%, gas-fired power generation as 14%, wind 7%, hydroelectric power is 4%, Geothermal, biomass, and photovoltaic power generation accounted for the proportion of 3%, 1% oil. "However, Germany's coal-fired power is too high, this mix of energy sources on the new grid-connected energy of limited help.
"Fan Luke said. TUV South-German group smart grid project manager Christian Dirmeier said after Germany announced a drastic reductionV subsidies because, in addition to think outside of photovoltaic power generation efficiency and does not have the expected high, the deeper reason is PV installed last year growing too fast, and power grid "flexible" power percentage is too low. "Poor flexibility of coal and electricity, to high peak ' dynamic ' energy was relatively small. "Christian Dirmeier said," Germany today is GreekLooking to balance the ratio of energy in the grid.
"In fact, volatility of wind energy, solar energy has been criticized by the power grid, its total network for security breaches in a few large, also become a new energy grid is unwilling to accept most of the major causes. Introduction to Christian Dirmeier, as the use of new energy power, Germany in power grid constructionCost of 500 billion euro, but every year there are 20% of power loss. "The role of smart grid becomes more and more important
tera power leveling, it is less stable, and in the process of helping manufacturers in the transport and communications more smoothly and reduce losses. "Fan Luke, in addition to the smart grid, power grid enterprises should explore the smart power. Different from the previous gt, ' smartPower generation ' crew to quickly increase or decrease the load, is not affected by the increase or decrease in the number of restrictions. "Start within 1 minute to the grid number MW-level power, 5 minutes from the start reached full capacity, within 1 minute you can stop quickly.
"Fan Luke explained. He said, "smart power" unit cost per kilowatt cost about 500 euros, compared to traditional gas turbine, butSingle run more efficient and minimize the unit at peak time brought about by high maintenance costs. "If in generation-side can do intelligent, coupled with the application of the smart grid, including energy and utilities, such as gas-electric flexible power supply, than in the new energy in the grid is in principle unlimited. "Fan Lu said.
