"- Too nervous." On the 13th, at 10 East Road in Jinan City, as the one in charge of the enterprise to the economic Herald reporter that, because of limited production, enterprises can not be completed on time, orders were claims.
Entered August, the electricity shortage and decline of coal affected by factors such as quality, Shandong Province experienced 10 of Electrical Scarcity is not the case, the biggest power grid gap 10.22 million kilowatts, the power needs of the province close to 1 / 3.
Some experts believe that the power structure in Shandong Electrical Scarcity will be a single issue completely exposed. At present, over 96 percent of Shandong's generating capacity comes from thermal power, 40 percent of the electricity supply needs of the redeployment from other provinces. "The restructuring of the power of Shandong is already imminent, the new alternative energy development should quickly follow-up."
In this context, people began to look to wind power and solar power, hope that through the use of renewable energy resources sufficient to reduce the burden of the Shandong power grid.
Wind Power: How to four landed the Three Gorges Hydropower Station
In Shandong, the huge resource potential, good prospects for the development of renewable wind energy was elected.
This reporter has learned that Shandong to the development of wind energy resource reserves of 88 million kilowatts, accounting for the development of wind energy resources can be total reserves of 8.8%, equivalent to four Three Gorges Hydropower Station (18.2 million kilowatts) of installed capacity. Shandong Electric Power Engineering Advisory Centre on the basis of this estimate, our province Weihai, Weifang, and Binzhou and Dongying, Qingdao, Rizhao, and other places are building wind power plants with natural conditions.
Based on this, wind power has been high hopes. 1998 the first wind farms built, wind power projects in Shandong Province to speed up the pace. As of the end of June this year, the province has installed 331 wind turbine units installed capacity of 361,600 kilowatts." Shandong Provincial Development and Reform Commission of the Said, "At present, new projects approved in the installed capacity of close to 1 million kilowatts."
Nevertheless, with the province's installed capacity of 55.94 million kilowatts of electricity and the use of wind energy resources can be compared to the total reserves, wind power is negligible. What is the constraint in the end the wind power generation process »
It is understood that the investment cost of wind power, is the major factor in the slow results. Shandong Long Island wind power generation limited liability company's staff Mr. Wang told reporters, Long Island wind power throughout the province is the first wind farms. 1999, South Island-installed power generating units 9 typhoon began and power generation network. As of now, the company has 31 wind generators Taiwan, the total installed capacity of 20,000 kilowatts, 22 million yuan sales revenue. "If you do not calculate maintenance costs, loan interest, after 10 years we have been able to recover the cost."
At the same time, the power generation business, the Internet tariff is also crucial. Mr. Wang said, and cost about 4,000 yuan / kW coal power plant compared to conventional energy, wind power per kilowatt installed capacity of the cost of 8,000 yuan -10000 yuan. "That is why, from September 1 last year from the" full acquisition of enterprise grid renewable energy electricity regulatory approach ", wind power prices for Internet access 0.76 yuan / kwh, the wind power companies to lift the high cost of To worry about. "
However, wind power companies did not expect that, after less than a year, the State Development and Reform Commission once again adjusted the price of wind power the Internet, Shandong from the original 0.76 yuan / kwh fell to 0.61 yuan / kwh. "The price adjustment, we will certainly be a loss." Mr. Wang even asserted that the province's wind power companies are operating loss. Moreover, the new Internet prices will curb the existing wind power enterprises to expand the scale of the initiative. "After the price adjustment, many wind power companies shout deficit." Shandong Provincial Development and Reform Commission official told reporters that they were actively understand the actual situation. Because wind power is "on heaven", the weather factors should not be overlooked. According to informed sources, at present, Shandong wind power generating capacity equivalent to only 10 million kilowatts of thermal power generation capacity.
Optimistic about the prospects for wind power generation, Shandong is actively speed up the construction of wind power. Reporters from the Shandong Provincial Development and Reform Commission that, by the year 2010, the province's wind power capacity will increase to 1.5 million kilowatts; to 2015, wind power installed capacity to reach 3 million kilowatts, accounting for the province were installed capacity of electricity The total 2.05 percent, 2.56 percent.
But in the current cost of electricity and Internet access do not match the circumstances, the enterprises to invest in wind power from what is »
Solar power: how to tap the "73.1 billion tons Biaomei"
In addition to abundant wind power, solar energy is also the advantages of Shandong. The province nearly 2 / 3 of the area in daylight hours in more than 2,200 hours, more than the total amount of solar radiation per square metre in 5000 MJ, solar radiation, the total value of 73.1 billion tons of standard coal equivalent. However, reporters found that in the interview, Shandong Province solar energy production enterprises which are produced by solar products, 90% exported to Europe and America, the domestic sales is limited, solar energy structure in Shandong proportion of minimal.
Shandong Provincial Development and Reform Commission official, the solar power generation in Shandong has just started, the high cost of its difficult showcases the reason why.
According to reports, solar cells will be a direct conversion of solar energy into electrical energy of semiconductor devices. At present, China is more than 90 percent of solar cells rely on imported raw materials, high cost, solar power costs to decline. In addition, to lower solar power costs, you must continuously improve photoelectric conversion rates, and the current photoelectric conversion rates lower, a short period of time to a major breakthrough. “ "Shandong Science and Technology Park of Connaught 30 kilowatt photovoltaic project well-functioning, and formed a battery-from-home with the industrial chain, but the product input costs too high, if not the Government's policy of subsidies, large-scale promotion difficult to achieve." Shandong Nuorui Te New Energy Co. Ltd. of Shanghai, general manager of civilization told reporters that at present, solar power cost thermal power costs almost 10 times the cost.
Civilization that Shanghai, Shandong to the solar power generation and aim to succeed, should take the lead in exploring renewable energy electricity pricing policy and taxation mechanism, such as photovoltaic power generation on whether to give preferential policy of subsidies to certain investors the benefits of protection. "In Germany, price is 0.14 euros / kWh, and if users will own the roof of the solar photovoltaic power plant sold, will be 0.56 euros / kWh subsidies. Because such a policy support, triggered a A solar energy investment flows, the German solar energy than the prevalence rate several times higher than in other countries. "
New solar power plant covers an area of broad, Shandong and more small situation in the province will not allow the building of large-scale solar power plants, but they can carry out timely city network building's roof and solar photovoltaic demonstration projects, and gradually extended to various industries , Commercial and civil construction.The information available to reporters, in 2010, Shandong Province in the coastal cities of the implementation of "photovoltaic roof plan" to build 30,000 kilowatts of photovoltaic power generation system.
