Clean and low-carbon, energy structure transformation

By the end of the 14th Five-Year Plan, renewable energy will change from the incremental supplement of energy and electricity consumption to the incremental main body

Data show that by the end of 2020, China's hydropower installed capacity of 370 million kilowatts, wind power installed capacity of 280 million kilowatts, photovoltaic installed capacity of 250 million kilowatts, biomass power installed capacity of 29.52 million kilowatts, respectively for 16 consecutive years, 11 years, 6 years and 3 years ranked first in the world. If you take the total installed capacity of 22.5 million kilowatts of the Three Gorges power Station to compare, 930 million kilowatts of renewable energy generation capacity is almost equivalent to 41 Three Gorges power stations.

"Renewable energy emits neither pollutants nor greenhouse gases, and has achieved remarkable results in reducing pollution and carbon." Zhang Jianhua said that by 2020, China's renewable energy development and utilization scale is equivalent to replacing coal by nearly 1 billion tons, reducing carbon dioxide, sulfur dioxide and nitrogen oxide emissions by about 1.79 billion tons, 864,000 tons and 798,000 tons respectively, providing a strong guarantee for the fight against air pollution. At the same time, with the significant improvement of the level of technology and equipment, the cost of renewable energy generation has continued to decline, the average cost of onshore wind power and photovoltaic power generation projects per kilowatt has dropped by 30% and 75% respectively in the past 10 years, and the industrial competitiveness has rapidly improved.

To ensure that the target of carbon peak and carbon neutrality is achieved on schedule, what new characteristics will be presented in the "14th Five-Year Plan" renewable energy development pattern? "Facing the new situation and new tasks, the boundary conditions, development logic and development mechanism of renewable energy development will undergo a series of major changes." Li Chuangjun, director of the New Energy and Renewable Energy Department of the National Energy Administration, summarized the four characteristics:

- "Large-scale", by the end of the "14th Five-Year Plan", renewable energy generation capacity will account for more than 50% of China's total electricity installed capacity.

- "high proportion", by the end of the "14th Five-Year Plan", it is expected that the proportion of renewable energy in the increase of electricity consumption in the whole society will reach about 2/3, the proportion in the increase of primary energy consumption will exceed 50%, and renewable energy will change from the original incremental supplement of energy and electricity consumption to the incremental main body of energy and electricity consumption.

- "Marketization", further play the decisive role of the market in the allocation of renewable energy resources, from this year, the development of wind power photovoltaic will enter the parity stage, get rid of the dependence on financial subsidies, and achieve market-oriented and competitive development.

- "High quality", the "14th Five-Year Plan" will enhance the absorption and storage capacity of new energy, not only to achieve large-scale development of renewable energy, but also to achieve a high level of consumption and utilization, and more effectively ensure the reliable and stable supply of electricity.

We will vigorously enhance the flexible adjustment ability of the power system, and build a new type of power system with new energy as the main body

Wind power, photovoltaic and other new energy to a certain extent "depend on the sky to eat", with volatility, intermittent and other characteristics, the future large-scale high proportion of access, how to ensure the stable supply of power and achieve a high level of consumption and utilization, is a concern of the industry. The ninth meeting of the Financial and Economic Commission of the CPC Central Committee held recently proposed to build a new power system with new energy as the main body.

In this regard, Huang Xuenong, director of the Power Department of the National Energy Administration, introduced that the next step will be to build a power generation, supply, storage and marketing system that ADAPTS to the development of large-scale new energy, enhance the flexible adjustment ability of the power system, promote the interactive integration of source and network load and storage, increase the promotion and application of key technologies of the new power system, and promote the construction of the power market and institutional innovation. To ensure a steady supply of electricity.

In terms of improving the flexible adjustment ability of the power system, Huang Xuenong said that on the power generation side, it is necessary to strengthen the flexible transformation of thermal power, and promote the construction of pumped storage power stations and natural gas peaking power stations; On the power grid side, it is necessary to increase infrastructure construction, improve the ability to optimize the allocation of resources, and in particular, give play to the mutual benefit of large power grids. On the user side, promote the replacement of terminal electric energy, especially green electric energy, to improve the response ability on the demand side; In addition, it is necessary to accelerate the large-scale development of energy storage, promote the comprehensive digitization of the power system, and build an efficient and intelligent scheduling and operation system.
