In 2009 for the global wind energy market, it is very difficult year, credit and investor confidence Compaq Laptop Battery decreased. However, as wind power is to reduce carbon dioxide emissions, one of the main ways, many governments have already indicated that he would continue to support the national policy of the wind power industry. On the issue of energy security and global warming concerns, as well as the increased demand for electricity in developing countries and Japanese competitive wind farm construction costs, have decided the global wind power market will grow steadily, policy support and other factors will be to make wind energy industry to survive the financial crisis.
World-renowned growth consulting company Frost & Sullivan research shows that in recent years, global wind power industry, in general, show a sustained, rapid development trend of the growth of the world's wind power industry in key areas began to shift from Europe to Asia and North America. In 2008 the world's new wind power installed capacity of about 27.26 million KW, an increase of 29% over last year, the cumulative installed capacity reached 121 million KW, an increase of 42%. 2008 global wind power capacity of 260 billion KW.h, in the global proportion Laptop Battery of total generating capacity in 2000 of 0.25% to 2008 by 1.5%. Cumulative wind power installed capacity up to 10 countries accounted for 86% of the world's total installed capacity.
The status quo of China's wind energy industry
The size of the Chinese mainland for the development of wind energy resources are mainly concentrated in the interior of the northeast, northwest, north and Qinghai-Tibet Plateau areas, such as Xinjiang, Inner Mongolia, Gansu and other places, as well as the southeast coast and nearby islands, its annual wind speed at 3m / s over time of nearly 4000h or so, in some areas the average annual wind speed of up to 6 ~ 7m / s and above, with a great value to the development and utilization.
As the wind energy resource-rich, China's wind Presario 900 power industry, long-term development prospects, but growth will slow down compared to previous years. China's installed capacity of wind power from 2001 to 402,000 KW up to 2008's 8.38 million KW, since 2004 China's installed capacity of wind power growth has been higher than the global average. Frost & Sullivan estimated that by 2020 the total installed capacity of wind power in China will exceed 150 million KW, 2009 ~ 2020 the cumulative installed capacity of the compound annual growth rate of 20% ~ 30%, far lower than the previous years growth rate of close to 100% of the installed capacity.
China's wind energy market investment opportunities
The Chinese government will soon introduce a new energy industry revitalization plan will greatly increase the wind power installed capacity. According to Frost & Sullivan forecast that by 2020, China's wind power installed capacity will break through 150 million KW, the state will focus on construction of the following six Grade 10 million KW of wind power base: Presario 1700 10 million KW of Gansu Jiuquan wind power base construction plan-level total installed capacity of 35.65 million KW, has completed the first phase of the wind turbine to invite tenders. The rest of 10 million KW wind power base in the planning stage are as follows: Xinjiang Hami planning 20 million KW; Inner Mongolia, planning and construction of 50 million KW, which Mengxi 20 million KW, Mondon 30 million KW; Hebei planning in coastal and northern areas of the building 10 million KW; Jiangsu Province plans to build 10 million KW, of which 7 million offshore KW.
China's current investment in wind farm developer is mainly the central and Armada E500
local state-owned power generation enterprises and state-owned energy enterprises, private enterprises and foreign-funded enterprises less. New installed capacity in 2008, the five power generation groups and energy group projects about 76%. Wind power operators in the degree of concentration is increasing.
China's wind energy investment opportunities in the manufacturing sector
At present, China's domestic wind power industry has become covered by leaves, gear boxes, generators, towers and other major components of the production system. Wind power machine according to supply and demand situation, leaves and machine production capacity the past two years more than the projected market demand for the next two years, overcapacity will occur. According to the Chinese government's wind power development plan, 2009 to 2010 will add 10 million KW, and 12 million KW. Statistical machine the major domestic manufacturers of A1175 wind power capacity expansion plans, 2009 and 2010, respectively machine efficient market capacity reached about 1100,1900 million KW.
Huarui from the wind power, gold wind technology and Dongfang Electric capacity projections, which the top three firms in 2009 and 2011 capacity is expected to reach 7.6 million, respectively, 11 million and 15 million KW. Moreover, China's current production of wind power machine manufacturers in their sixties and seventies, mostly in 2006 and 2007 began to research and development.
2009 ~ 2010 will enter the small-batch production phase, the wind power machine manufacturers will start in the next few years the fierce market competition, excess capacity of wind power machine is bound to lead to product prices and profit margins decline. Currently fan margins are not high, gold wind technology, for example, in 2008 the product gross margin was 18% ~ 28%, Dongfang Electric's gross margin in 2008 is only around 11%.
Domestic leaf production enterprises increased A1185 rapidly in recent years. At the same time, since the share of higher-value machine, wind power machine companies also tend to produce their own blades. Domestic leaf production has increased rapidly over the future market demand.
However, the supply of bearings there are still some gaps, there is a market for investment opportunities. Wind turbine main bearing is currently almost entirely dependent on imports of other parts of bearings, such as yaw bearings and variable propeller bearings, domestic production of only a few companies can. Technical barriers to wind power bearing higher from the current situation, due to the ordering of key equipment such as machine tools need a certain cycle, therefore, wind power bearing to achieve a balance between supply and demand of the time will be late, bearing the high gross margin is expected to be able to a longer period of time can be maintained.
China's wind energy investment opportunities in complementary markets
Frost & Sullivan believes that wind power generation supporting industries in the energy storage battery market presents tremendous investment opportunities. Energy storage battery can solve the intermittent wind power impact on power issues, to ensure the continuity and stability of the transmission grid.
When the grid-style large-scale wind farms installed capacity accounted for a total capacity of grid system where the ratio of 10% or more, we need to stabilize M9324 the voltage of the battery energy storage. The assimilative capacity of wind power for local consumption by the local power structure of state influence. Measure of the local consumptive capacity of wind power indicator is mainly wind power penetration limit, that is, installed capacity of electric power system, stroke, the proportion of total system installed capacity, that is, peaking power capacity margin to accommodate the wind power installed capacity. The structure of power generation installed capacity in different areas, its consumptive capacity of wind power is different. According to wind power around the building and planning level, the 2010 Inner Mongolia, Gansu and northeast wind power installed capacity will reach the local power grid for more than 10% of the total installed capacity has exceeded regional power-consumptive wind power capacity to the limit. In addition, wind power can cause power quality decline, M8403 harmonic pollution, large-scale wind power grid can cause power grid voltage and frequency instability. In order to ensure safe and stable operation of power grid, power grids, battery energy storage needs for support.
Large-scale wind farm storage capacity of the battery for more than MW. Energy storage battery can power the effective use of peak-valley difference, improve the efficiency of power transmission and distribution equipment to address the local voltage control problems, improve electricity reliability and power quality improvement. With the rapid development of wind power generation, energy storage and battery power will be safe, stable and efficient operation of an important ancillary facilities.
Wind power energy storage battery can choose to use lead-acid batteries, nickel-metal hydride batteries, lithium batteries, sodium sulfur batteries, alum batteries and super capacitors. At this stage, lead-acid type battery technology is already mature, and nickel-metal hydride batteries, lithium batteries, sodium sulfur batteries, alum battery and super capacitor is still in development stage. As the lead-acid battery with a excellent performance and low cost, in the field of wind power energy storage battery there will be a better return M7318 on investment.
Valve-regulated lead-acid battery with its mature technology and low prices in the market were overwhelmingly dominant, but with the improvement of technology, the manufacturers, the price level more or less of lead-acid gel batteries for its longer life and greater The capacity will gradually become an alternative to the user is expected to 2015, gel batteries from the 2008 total market share of 5% to nearly 20%. Other types of batteries in the short term will not be able to replace lead-acid type of batteries market PowerBook G3 position.
