22 十二 11 Italy launched high-altitude kite wind generator
Over the past decade, wind has gradually developed into a major alternative energy, and be promoted worldwide. But the traditional wind power and wind speed by site factors such as larger, has many shortcomings. To this end, the Italian KiteGen technology companies eyeing the high-altitude wind energy, and developed a new MARS (Magenn AirRotor System) system.
MARS system not only has the advantages of high wind power generation efficiency, and the space and the area is also very small. In general, a generating capacity of 1000 MW of conventional wind power plants in the occupied area of between 250-300 square kilometers, and KiteGen technology companies claim to use the MARS system for power plants using only 5-6 square kilometers the area can achieve the same power capacity.
MARS system consists of high-altitude towing kites and ground power equipment of two parts. Towing kite and wind turbines connected to the ground and through the power generation equipment installed in the air on a kite rotation sensors to control the direction and path, in order to maximize the driving wind turbines spin and generate electricity. KiteGen said that although the system is still in the wind generators testing phase, but the prospects are very bright. Compared with the conventional wind power generation, MARS system has unparalleled advantages: It can be obtained from a stable high-altitude wind energy. The higher the kite flying high, as the average wind speed the greater the higher the efficiency of power generation, while the traditional wind turbines up to the average height is only 100 meters.
Moreover, according to company estimates KiteGen, MARS system per kilowatt hour of electricity costs about $ 0.02 to $ 0.05 per kilowatt hour of energy and fossil power generation cost between $ 0.05 to $ 0.09, compared with the traditional cost of wind power plants $ 0.15.
Mao by the MARS system by Bo Lite Mason (MassimoIppolito) invention. He then set up in 2007 KiteGen Technologies, headquartered in Italy eccentric. Currently, the home wind power generator system is further improved, the relevant standard operating procedures are developed. The company hopes to obtain sufficient funds to develop the first complete model.

18 十 11 China’s wind generator farm investments come from electricity generation
Fujian Pingtan Electric Power is about to transfer its 5 percent stake in Longyuan Pingtan Wind Power at a price of 19.08 million yuan while Fujian Electric Power is about to transfer its 10 percent stake in Fujian Wind Power at a price of 6.14 million yuan, according to recent announcements on the Shanghai United Assets and Equity Exchange.
Industry observers noted that the downturn of performance witnessed by both Longyuan Pingtan Wind Power and Fujian Wind Power in the first half of 2011 was likely to have been due to the stricter access threshold set by the United Nations Executive Board (UNEB) on clean development mechanism (CDM) project registration and subsidy.
According to the UNEB’s regulations, CDM projects can only be registered when the project’s rate of return is lower than the industry standard. In addition, CDM projects will not qualify for subsidy if the actual electricity generation substantially exceeds what has been estimated.
Longyuan Pingtan Wind Power, 85 percent of which is owned by the China Longyuan Power Group, has an installed capacity of 106 MW. It has generated sales revenues of 150 million yuan with net profits of 19.58 million yuan during 2010. In the first half of 2011, however, only 43.91 million yuan of net profits were made, with sales revenues amounting to 81.42 million yuan.
Fujian Wind Power, with a 90 percent stake owned by the China Longyuan Power Group, achieved 13.4219 million yuan of net profits in 2010 but encountered a loss of 1.8626 million yuan in the first half of 2011.
It is estimated that the loss was partly due to Fujian Wind Power’s failure to get a CDM subsidy because of excessive power generation.
Industry experts noted that the main returns on China’s wind farm investments come from electricity generation revenue, subsidy on the price of renewable electricity, and the CDM subsidy. However, the instability of wind power resources, restraints on wind power’s access to the national power grid, and the fast increasing installed capacity in the wind power industry has made the profitability of the wind power business rely more and more on the CDM subsidy.
