Since the 18th National Congress of the Communist Party of China, my country has unswervingly promoted the energy revolution, made historic achievements in energy clean and low-carbon transformation, and made solid steps in the high-quality development of energy.

The energy consumption structure continued to be optimized. Since the 18th National Congress of the Communist Party of China, my country's energy utilization efficiency has been continuously improved, and the average annual growth of energy consumption of about 3% has supported the average annual growth of the national economy of 6.5%. Clean and low-carbon has become the main direction of energy structure adjustment, the proportion of fossil energy consumption such as coal continues to decline, and the proportion of clean energy consumption continues to increase. By the end of 2021, the proportion of my country's coal consumption will drop to 56%, and the proportion of clean energy consumption will increase to 25.5%; the transformation of low-carbon and energy-saving production will be further promoted, the charging infrastructure and charging network for electric vehicles will continue to improve, and the level of terminal electrification will steadily increase; The number of energy vehicles has reached 7.84 million, showing a continuous high-speed growth trend.

2. Energy clean and low-carbon transition faces new situation and new requirements

General Secretary Xi Jinping emphasized that entering a new stage of development, the internal and external environment of my country's development has undergone profound changes, and it is facing many new major problems, which need to be correctly understood and grasped. At present, a century of changes and a century of epidemics are intertwined, economic globalization is facing headwinds, the world has entered a new period of turmoil and change, a new round of technological revolution and industrial transformation is in-depth development, and the global response to climate change has taken on a new situation. Accelerating the transition to clean and low-carbon energy is an inherent requirement to ensure national energy security and to achieve carbon neutrality on schedule. It is also the only way to promote high-quality energy development and accelerate the building of a powerful energy country. Sexual change provides new opportunities and challenges.

The layout of the energy structure will undergo profound adjustments. Clean and low-carbon energy will be developed and utilized on a large scale, gradually replacing the dominant position of traditional fossil energy in the energy system. It is estimated that by 2030 and 2060, the proportion of non-fossil energy in primary energy consumption in my country will increase from 16% in 2020 to 25% and 80% respectively. The energy development method will present the characteristics of both centralized and distributed.

Energy utilization will be complex and diverse. The scope of electric energy utilization extends to many fields that did not use electricity before. Various new energy consumption methods and service demands such as electric vehicles, data centers, and energy efficiency services have emerged in large numbers. Electricity, gas, cold, heat, hydrogen, etc. are complementary and flexible. , Electricity-based terminal energy substitution has become the mainstream. The way of energy utilization is more diversified, personalized, comprehensive and interactive.

Energy technology innovation will accelerate integration and development. New technologies and new equipment in the fields of new energy development, multi-energy conversion, advanced energy storage, carbon capture utilization and storage, and energy system control continue to emerge. Digital technology and energy technology are deeply integrated, and energy systems are smarter, more open, and More efficient and friendlier.

The energy industry ecology will accelerate leapfrogging and upgrading. A large number of energetic new market players have entered, and traditional energy companies have accelerated their transformation, giving birth to a large number of new businesses, new formats, and new models, such as integrated energy services, energy big data, platform businesses, and energy aggregators. The industrial chain structure and ecology have undergone profound changes , forming a new energy ecosystem.

Electric energy is a clean, efficient, and convenient secondary energy source. Electricity is a key field for energy clean and low-carbon transformation. The development and utilization of new energy resources, power generation is the main method. To replace terminal fossil energy consumption, electricity is the main choice. To promote energy technology innovation and industrial cultivation, electric power is an advantageous field. With the acceleration of the "dual carbon" process and the in-depth advancement of energy transformation, the traditional power system is evolving into a new power system that is clean and low-carbon, safe and controllable, flexible and efficient, open and interactive, and intelligent and friendly. Its technical foundation, operating mechanism and functional form Profound changes will take place, and the power system will also face unprecedented pressure to change and upgrade.

From the supply side, it is reflected that clean energy power generation has gradually become the main body of installed capacity and electricity. The key to promoting clean and low-carbon energy transformation is to accelerate the development of non-fossil energy, especially new energy such as wind power and solar power. About 95% of non-fossil energy in my country is mainly converted into electricity for utilization. It is estimated that by 2030, the installed capacity of wind power, solar power and other new energy power generation in my country will surpass coal power and become the largest power source; by 2060, the proportion of new energy power generation is expected to exceed 50%, becoming the main power generation.

From the perspective of consumption, it is reflected in the high electrification of terminal energy consumption and the emergence of a large number of "prosumers" of electricity. It is estimated that the electrification level of my country's terminal energy consumption will increase to about 39% and 70% in 2030 and 2060. With the rapid development of multiple power loads and energy storage, many power users are both power consumers and producers, and the relationship between power production and sales has undergone profound changes.

From the perspective of the power grid, it is reflected that the development of the power grid will form a pattern dominated by the large power grid and the coexistence of various grid forms. The AC-DC hybrid large power grid is still the leading force in the optimal allocation of energy resources. At the same time, micro-grids, distributed energy, energy storage and local DC power grids will develop rapidly, interoperate with large power grids, and coordinate operations to support various new energy sources. Development and utilization and friendly access to various loads.

From the perspective of the system as a whole, it is reflected in the profound changes in the operating mechanism and balance mode. With the replacement of conventional power sources by a large number of new energy power generation, and the widespread application of adjustable loads such as energy storage, the characteristics of the "double high" (high proportion of renewable energy and high proportion of power electronic equipment) of the power system have become more prominent. The power system will gradually change from a real-time balance of source and load to an incomplete real-time balance of coordination and interaction of source, network, load and storage.

3. Promoting clean and low-carbon transformation of energy requires accelerating the construction of a new power system

The new power system is an important part of a clean, low-carbon, safe and efficient modern energy system. The construction of a new type of power system is a major deployment made by the Party Central Committee with Comrade Xi Jinping as the core, focusing on strengthening the construction of ecological civilization, ensuring national energy security, and achieving sustainable development. It also provides a Chinese path and a Chinese solution for the sustainable development of global electric power. The power grid is a key link in building a new power system. Based on the functional positioning of the power grid, the State Grid proposes and adheres to the principles and requirements that clean and low-carbon is the direction, energy supply is the foundation, energy security is the key, energy independence is the foundation, energy innovation is the driving force, and energy conservation and efficiency improvement should be boosted.

The National Wind-Storage Storage and Transmission Demonstration Project is the world's largest new energy demonstration power station project integrating wind power generation, photovoltaic power generation, energy storage systems, and intelligent power transmission. Relying on this demonstration project, State Grid successfully completed the first grid-related performance test of a high-proportion new energy system at home and abroad. The project helped all the venues of the Beijing Winter Olympics to achieve 100% green electricity supply, and "the wind in Zhangbei lights up the lights in Beijing" has become a shining business card for the Green Winter Olympics. The picture shows the national wind-solar storage and transmission demonstration project located in Zhangbei County, Hebei Province.

Adapt to the increasingly platform-based energy allocation and innovate the way of power grid development. As a big manufacturing country, China must be in its own hands if it wants to develop its real economy. my country's energy resources and demand are reversely distributed, and the energy bases in the west and the load centers in the east and middle are generally 1,000-3,000 kilometers apart. State Grid continues to improve the core backbone grid structure, accelerates the construction of power grids at all levels, coordinates efforts on both sides of supply and demand, actively serves the development of new energy, and promotes the orderly replacement of fossil energy by clean energy. A total of 29 stable, safe and reliable UHV power transmission projects have been built, with the longest power transmission distance reaching 3,300 kilometers, and the inter-regional and inter-provincial power transmission capacity exceeding 240 million kilowatts, becoming the power grid with the longest power transmission distance and the strongest energy resource allocation capability in the world. Resolutely shoulder the responsibility of ensuring the power supply network, firmly guard the security defense line of the large power grid, and regard the protection of people's livelihood as the top priority of ensuring power supply, which has played an important role in the big test of disaster relief, epidemic prevention and control, etc.

During the "14th Five-Year Plan" period, it is planned to invest 2.4 trillion yuan in power grids to vigorously promote the construction of a new energy supply and consumption system. On the one hand, continue to improve UHV and power grids at all levels, serve the construction of large-scale wind power photovoltaic bases in deserts, Gobi, and deserts, support and promote the intensive development and long-distance transmission of large power bases; on the other hand, accelerate the construction of modern smart The distribution network promotes the development of micro-grid and distributed energy, and meets the convenience and plug-and-play of various power facilities.

General Secretary Xi Jinping pointed out that we must base ourselves on my country's endowment of energy resources, insist on establishing first and then destroying, and comprehensive planning. The gradual withdrawal of traditional energy must be based on the safe and reliable replacement of new energy. After the Party Central Committee proposed the "dual carbon" goal, the State Grid immediately researched and deployed it, issued an action plan for the implementation of the "dual carbon", and introduced a series of practical measures. New energy power generation is easily affected by the climate environment, and its output is unstable. It has obvious characteristics of "extreme heat and no wind, extreme cold and little light". State Grid vigorously develops pumped storage power stations to improve system regulation capabilities. By the end of 2021, the scale of pumped storage power stations in operation and under construction in State Grid's operating areas will reach 26.31 million kilowatts and 46.43 million kilowatts, respectively. Through the complementarity of wind and water and the mutual assistance of the surplus and shortage of large power grids, it has set a world record for 31 consecutive days of clean energy power supply in Qinghai Province. By the end of 2021, the installed capacity of new energy in the operating area of the State Grid will reach 540 million kilowatts, and the utilization rate of new energy will reach 97.4%, making it the grid with the largest installed capacity of new energy grid-connected in the world.

The State Grid will support the energy-saving and carbon-reducing retrofit, flexibility retrofit, and heating retrofit of existing coal-fired power units. 100 million kilowatt transformation task. Adhere to the concept of open development, strengthen cooperation with all parties in the society, accelerate the construction of pumped storage power stations, and strive to reach 50 million kilowatts and 100 million kilowatts of pumped storage installed capacity in the company's business area in 2025 and 2030, respectively. Support the large-scale application of new energy storage. It is estimated that the installed capacity of new energy storage in the company's business area will reach 100 million kilowatts in 2030. Through comprehensive measures and multiple measures, promote the consumption and utilization of new energy.

Adapt to high electrification of energy consumption, promote energy saving and reduce consumption to meet multiple energy demands. General Secretary Xi Jinping emphasized that in the field of consumption, it is necessary to enhance the people's awareness of conservation, advocate a simple, moderate, green and low-carbon lifestyle, and oppose extravagance, waste and excessive consumption. The level of electrification is an important symbol of the progress of modern civilization, and improving the level of electrification on the consumption side is an important way to promote the continuous optimization of the energy consumption structure. The State Grid is stable and orderly, and promotes electric energy replacement according to local conditions. In the northern region, it promotes the use of electricity to replace coal for clean heating, and comprehensively implements electric energy replacement projects such as all-electric scenic spots, all-electric ships, and electrification of roads and railways. A total of 867.7 billion kwh of electricity has been replaced. It is equivalent to reducing scattered coal burning by 480 million tons and reducing carbon dioxide emissions by 870 million tons. Accelerate the construction of charging infrastructure, build a "ten vertical, ten horizontal and two ring network" fast charging network, and effectively alleviate the "mileage anxiety" of electric vehicles for long-distance travel.
