New energy for high-quality development add motivation
2017-12-20

New energy "light" new hope. At present, the energy structure of our country is shifting from a coal-based economy to a diversified one. The impetus for energy development is shifting from the growth of traditional energy sources to the growth of new energy sources. The process of clean and low-carbonization is accelerating and the picture of beautiful China is constantly being stretched.


Photovoltaic power generation installed capacity exceeded 100 million kilowatts; the first successful test of combustible ice in the sea area added another "new member" of minerals; the high temperature dry-hot rock mass of 236 degrees Celsius was drilled at 3705 meters in the Republican Basin of Qinghai Province ... Since this year, Many bright spots in the field. However, behind the achievements, new energy and what are the opportunities and challenges? The journalist made an interview about this.


The energy mix is shifting from coal to diversification


New energy "light" new hope. At present, the energy structure of our country is shifting from a coal-based economy to a diversified one. The impetus for energy development is shifting from the growth of traditional energy sources to the growth of new energy sources. The process of clean and low-carbonization is accelerating and the picture of beautiful China is constantly being stretched.


The scale has been expanding. As of the end of November, China's wind power installed capacity reached 160 million kilowatts, installed photovoltaic power generation reached 126 million kilowatts and biomass power generation installed capacity reached 15 million kilowatts, up 11.8%, 67.1% and 23.6% respectively over the same period of last year. According to the information released by the International Energy Agency, global solar PV capacity will increase by 50% in 2016, of which China contributed over half. From the perspective of renewable energy, it is estimated that by the end of 2017, the installed capacity of renewable energy power generation in China will reach 656 million kilowatts, an increase of 110% compared with 2012 and an average annual growth rate of about 16% in the past five years.


Structure continues to be optimized. On the one hand, new energy development is moving from concentrated resource areas to concentrated load areas. "At present, we are optimizing the layout in accordance with the principles of centralized development and decentralized development, long-distance delivery and immediate consumption. Taking photovoltaic as an example, the proportion of new installed capacity in Northwest China dropped by 17 percentage points this year, while that in East China and Central China Respectively, by 9 percentage points and 6 percentage points respectively. "Li Chuangjun, deputy director of the New Energy and Renewable Energy Department of the National Energy Administration, told us. On the other hand, the new pattern of centralized and decentralized development of new energy is gradually taking shape. "Distributed generation has the advantages of small power loss, low transmission cost and less land and space resources. By the first 11 months of this year, distributed photovoltaic installed capacity reached 17.23 million kilowatts, an increase of 3.7 times over the same period of last year."


Use the level of improvement. Abandoned wind abandoned has always been a new energy development "chronic disaster." In the first three quarters of this year, the abandonment and abandonment rates were 12% and 5.6% respectively, down 6.7 percentage points and 3.8 percentage points respectively from the same period of last year while the drop rates in key areas such as Xinjiang and Gansu dropped by 12 .1 percentage points and 10.5 percentage points. Guo Jiefeng, a researcher at the Institute of Resources and Environmental Policy of the State Council Development Research Center, believes that new energy technologies are also constantly improving. "The efficiency of photovoltaic power generation in China was about 14% -16%, and now it can reach 16% -18%. A little better It can even reach about 20%. "


Clean and efficient, but also facing growth problems


The data of the 19th National Congress of the Communist Party of China proposed to promote the revolution in energy production and consumption and establish a clean and low-carbon, safe and efficient energy system. Promote clean and low-carbon development, new energy credit is not small.


"Wind power, solar power and solar thermal energy will not emit pollutants and greenhouse gases during energy production, but will also significantly reduce the energy consumption of various types of non-renewable energy resource and at the same time reduce the ecological damage caused by coal mining and the water consumption of coal-fired power generation. Materials from the growth to the final use of the entire life cycle of carbon dioxide emissions do not increase, biomass power generation emissions of sulfur dioxide, nitrogen oxides and soot and other pollutants are far less than coal-fired power generation. "Li Chujun introduction, as of November, 271.8 billion kilowatts When the wind power generation has replaced about 80 million tons of standard coal, carbon dioxide emission reduction reached 150 million tons.


Rapid development at the same time, new energy is also facing many growing troubles -


Cost issues remain one of the major bottlenecks. "We conducted a simple estimate, the new energy power generation ratio of 10%, the cost of the entire system of consumer costs need to rise about two percent.New energy without Internet access, loss of opportunity costs; Internet, you need to absorb the cost.If the cost is unbearable, It is possible that abandoned wind will be discarded, "said Lin Boqiang, dean of the China Energy Policy Research Institute at Xiamen University. In addition, inter-provincial trans-regional transmission over the Internet costs also exist too high a problem. "Yunnan Hydropower sent to Guangdong average price of 0.2375 yuan per kilowatt-hour, but the cloud sent to Guangdong to send power transmission cost of 0.1995 yuan per kilowatt-hour, the framework of the agreement accounted for 45% of the cost of electricity, the framework outside the proportion of electricity transmission costs Reached 57%. "Li Chuangjun said.


Institutional mechanisms that give priority to development are still not sound. Li Chuangjun introduction, for now, the barriers between the provinces still exist, in the case of the power of the overall affluence, some local governments give priority to protect the province by administrative means coal-fired generating units, to absorb foreign new energy power is not high enthusiasm in To a certain extent, hinder the cross-provincial new energy consumption across the board. In addition, the price of traditional non-renewable energy resource is still hard to reflect the scarcity of resources and the environmental protection expenditure, reducing the competitiveness of the new energy industry.


Subsidy funds clearing cycle longer. "In recent years, there has been a big gap in funding for new energy subsidies. Some subsidies will take only about two years, increasing the financial burden on power generation enterprises, affecting the enthusiasm of enterprises in developing new energy sources, forming a triangular debt in the industry and even There is a phenomenon that some enterprises pay insufficient interest to settle their electricity bills and the risk of production and operation of the enterprise increases. At the same time, the subsidies to arrears have delayed the further adjustment of photovoltaic power and wind power prices, Li said.


From focusing on installed capacity to focus on the actual power generation changes


In the past to develop new energy sources, what we pursued more was from scratch, from childhood to age. Into a new times, the center of gravity is positive to improve the quality of development changes. How to continuously optimize the energy structure to achieve clean and low-carbon development?


On the one hand, we must speed up technological progress. "A while ago in Saudi Arabia, a photovoltaic project bidding, the lowest level of leveling costs 1.786 cents / kWh, equivalent to about 0.12 yuan, the current cost of photovoltaic power generation in the country about 0.5-0.7 Yuan / kWh or so.Technological level, the cost reduction potential is still quite big. "Li Chuangjun told us.


According to the "Thirteenth Five-year Plan for Geothermal Energy Development and Utilization", the total area of geothermal heating (cooling) by 2020 will reach 1.6 billion square meters. In Guo Jiao-feng's opinion, the geothermal market in our country has great potential, but there is still a gap between the current geothermal power generation technology and the international advanced level. The state can concentrate its efforts on tackling key technologies.


On the other hand, we must speed up the improvement of related mechanisms. According to the information, in view of the current outstanding abandonment and abandonment of light difficulties, the NEA will perfect the renewable energy priority generation system in the next step, expand the range of renewable energy allocation by means of trans-regional power transmission channels, and take the self-provided power plants participate in the peak load operation of the power system , To carry out special deals on renewable energy and electricity, alternative measures for clean heating and other electric power to expand the local consumption of renewable energy.


"Next year pilot areas will also carry out distributed power generation market-oriented transactions, which is equivalent to selling electricity across the wall, opening up a gap in the unified power grid." Li Chuangjun said: "Green development and energy transformation are the inevitable trends. All of you have Consensus: Our concept should shift from focusing on the kilowatts to focusing on the kilowatt - hours, that is, changing the focus from installed capacity to actual generating capacity and pay more attention to the quality of new energy development.
