With the development of wind power and other new energy industries, China's new energy power generation capacity plus hydropower capacity accounted for 70% of the total new installed capacity in the first three quarters of this year. At the same time, China's wind power has great potential for absorption and development. Wind power needs to find a new development mode, gradually withdraw subsidies from new energy sources in different types, fields and regions, and basically realize the development of wind power independent of subsidies by 2020 to 2022
In the past 10 years, China's energy transformation process has been accelerating. Wind power industry has made remarkable achievements in the world. How to develop in the future has attracted much attention. At the "2017 Beijing International Wind Energy Conference" held a few days ago, Liang Zhipeng, deputy director of the New and Renewable Energy Department of the National Energy Administration, said that wind power needs to take the lead in getting rid of subsidy dependence among new energy sources and must reduce costs and prices as soon as possible to contribute to social development.
Cost Expected to Lowest
This year, the number of participants and exhibitors will reach 36,000, and the exhibition hall will be expanded to 55,000 square meters. 650 enterprises from 23 countries and regions will participate in the exhibition, covering the entire industrial chain of wind energy development and utilization. "As a barometer of industry development, Beijing International Wind Energy Conference and Exhibition has become one of the world's top three wind energy exhibitions." Yao xingjia, director of the wind energy Committee of China renewable energy society, said.
With the rapid development of wind power industry, China's wind power has become the undisputed leader in global wind power. Data show that in 2008, China's installed wind power capacity was only about 12 million kilowatts, and the power generation from the Internet was only over 12 billion kilowatts, accounting for almost negligible percentage of the total power generation. By the end of 2016, China's installed capacity of wind power has reached 169 million kilowatts, generating 241 billion kilowatts of electricity, accounting for 4% of the total power generation. The power consumption structure has been continuously optimized.
At the same time, the industry has cultivated a perfect and sound industrial chain, leading the world in research and development and technological innovation. China's wind power equipment has been exported to more than 30 countries and regions, and the benefits of wind power in stimulating investment and employment are increasingly apparent.
"The diameter of the wind turbine used to be about 80 meters, but now it is about 110 meters. The height of the wind power tower has also increased from 80 meters to 120 meters or even 140 meters. The improvement of units has rapidly improved the power generation capacity of wind power. The current power generation capacity is about 20% higher than that five years ago, directly reducing the cost per kilowatt-hour. " Liang Zhipeng said that wind power used to be considered as an expensive energy source, but now it is the lowest priced new energy source in many places. The cost of wind power is still further reduced, and it will become the lowest-cost new energy and may even become the lowest-cost energy in the future.
Take the lead in getting rid of subsidy dependence.
At present, the development of wind power industry is still facing many challenges, the first of which is the problem of power rationing. China is the world's largest wind power market, and in recent years, the annual new installed capacity accounts for about 40% of the total new installed capacity in the world. The earliest development of wind power in China was in the "three northern" regions with the best wind energy resources. The overall installed scale of wind power in these regions has reached a relatively high level, while the proportion of electricity rationing is also the highest in the world.
"There is no China in the countries where wind power generation accounts for more than 10% of total electricity consumption, and the proportion in China is only 4%. This shows that the development of wind power in China is far from enough, and there is still great potential for absorption and development. " Liang Zhipeng said.
Another big challenge is the high price of wind power. In the first three quarters of this year, China's new energy power generation capacity plus hydropower capacity has accounted for 70% of the total new installed capacity. Liang Zhipeng said: "It is unreasonable to rely heavily on social subsidies if wind power cannot reduce prices."
This year's "Report on the Work of the Government" proposed that we should pay close attention to solving the mechanism and technical problems, give priority to ensuring renewable energy power generation and access to the Internet, and effectively alleviate the situation of water, wind and light abandonment. "This is the first time that the Government Work Report has made solving the problem of renewable energy utilization an important task. At present, some progress has been made in this work. It is believed that the problems of wind, water and light abandonment will be basically solved by 2020." Liang Zhipeng revealed.
"After more than 10 years of development, wind power needs to find a new development model. Subsidies will be gradually withdrawn from new energy sources in different types, areas and regions. By 2020 to 2022, wind power will basically develop independently of subsidies." Liang Zhipeng said.
Distributed Wind Power Becomes Air Outlet
In recent years, due to problems such as light abandonment and policies, photovoltaic development has shifted from the west to the central and eastern regions closer to the load center. The opening of distributed markets has brought new vitality to the photovoltaic industry. As wind power that encounters the same development bottleneck, where is the direction for the next decade?
"For the future wind power market, I think the opportunity lies in the central and eastern regions." Wang Haibo, president of Xinjiang Jinfeng Science and Technology Co., Ltd., said that in the past, the wind of 4 to 5 meters had no commercial development value, but now it is found that it is not lack of resources, but the technology may not have been achieved. Germany has a small land area, but the installed scale of wind power is as high as 50 million kilowatts. 80% of our country has abundant wind energy resources.
Tian Qingjun, vice president of Vision Energy, said that China has nearly 700,000 administrative villages. If 300,000 administrative villages adopt distributed energy, the market space will be very large. Therefore, the future low wind speed and distribution in the east must be a very broad blue sea market.
Wang Manchang, General Manager of China Shipbuilding Heavy Industry (Chongqing) Offshore Wind Power Equipment Co., Ltd., is also optimistic about the development of distributed wind power. He believed that at present the market, capital and resources are all available. First, the distribution is closest to the electricity load. Secondly, there are 1 billion kilowatts of medium and low speed wind resources of about 5 meters. Finally, small-scale wind power development has lowered the social capital threshold.
"The development of wind power in Europe was primarily distributed at the earliest, but China has taken the lead in developing centralized wind power. Now it is time to speed up the development of distributed wind power." Liang Zhipeng said that the development of distributed wind power in China is relatively difficult, firstly because of land conditions, secondly because of difficulties in accessing the power grid, and thirdly because we are not used to managing distributed renewable energy and providing related public services. Therefore, the recent important task is to improve relevant policies and government services so that distributed wind power can obtain a good development environment.
