“People’s Daily” (11th edition on June 13, 2022)

my country’s efforts to achieve carbon peaking by 2030 and carbon neutrality by 2060 are a major strategic decision made by the Party Central Committee with Comrade Xi Jinping at the core after careful consideration. It is related to the sustainable development of the Chinese nation and the building of a community of shared future for mankind. When presiding over the ninth meeting of the Central Finance and Economics Committee, General Secretary Xi Jinping emphasized that carbon peaking and carbon neutrality should be incorporated into the overall layout of ecological civilization construction, and the energy to grasp the iron and traces should be achieved to achieve carbon peaking and carbon neutrality by 2030 as scheduled. The goal of carbon neutrality by 2060. This meeting proposed to build a new power system with new energy as the main body. This is an overall plan made by the Party Central Committee to coordinate domestic and international situations. In order to implement Xi Jinping’s ecological civilization thought in the energy field, properly handle the relationship between development and emission reduction, overall and partial, short-term and medium-term, and unswervingly give priority to ecology, The green development road provides a practical path.

The construction of a new power system with new energy as the main body is of great practical significance for realizing the “dual carbon” goal. Energy is the foundation and driving force for the progress of human civilization, and the development of the energy field is closely related to the national economy, people’s livelihood and national security. In the new era, the development of my country’s energy sector is facing new challenges brought about by profound changes in the global economic governance structure and the global division of labor, as well as new requirements from the adjustment of the domestic energy structure. The construction of a new type of power system with new energy as the main body is based on the overall situation of my country’s economic and social development strategy, complete, accurate and comprehensive implementation of the new development concept, and a practical plan for carbon peaking and carbon neutrality. To build a new power system with new energy as the main body, the key is to “build first and then break”. Regarding the promotion of the energy revolution, General Secretary Xi Jinping emphasized that we must base ourselves on my country’s energy resource endowment, adhere to the principle of establishing first and then break through, and make overall plans. The gradual withdrawal of traditional energy must be based on a safe and reliable alternative to new energy. This has pointed out the way forward for us to promote the large-scale and high-proportion development of new energy, and promote the construction of a new power system with new energy as the main body through effective technology and industrial practice, under the premise of ensuring energy security. direction.

The development of pumped storage and the improvement of the power system’s ability to flexibly adjust are the key means to build a new power system with new energy as the main body. . One is to promote the large-scale development of new energy. Pumped storage can provide flexible adjustment capabilities for large-scale, high-proportion, and base-based new energy development. It is an indispensable stabilizer for power systems and is globally recognized as the most effective means of supporting wind, solar and other new energy development. The second is to effectively improve the level of new energy security. New energy sources such as wind and light have the characteristics of intermittent and randomness. It is urgent to build a batch of regulated power supplies with the characteristics of rapid response, controllable technology, economic advantages, energy saving and environmental protection, and large-scale application, so as to effectively guarantee the different development of our country. stage of energy security. Pumped storage has the functions of peak regulation, valley filling, and energy storage. It is the most mature, economical, low-carbon and safe regulating power supply in the power system that has been tested in practice. Accelerating the construction of pumped storage is of great value in ensuring the safety and reliability of energy alternatives and building new power systems. The third is to create a new growth point for the energy industry. Pumped storage projects can stimulate the development of related industries such as building materials and electrical equipment, and provide strong support for stabilizing growth and promoting investment. The construction of the pumped storage project will promote the development of new formats such as “pumped storage + health care” and “pumped storage + cultural tourism”, forming a new growth point for the energy industry.

In the process of building a new power system with new energy as the main body, my country has the conditions to build the pumped storage industry into an industry with large installed capacity, advanced technical capabilities, leading management level, and a high degree of independent innovation in the entire industry chain, and build a high-quality modern industry. industrial system. At present, efforts are being made from the following aspects: First, to accelerate the expansion of the industrial scale and to accelerate the development and construction of projects. During the “14th Five-Year Plan” period, the “Double 200 Project” will be implemented, and more than 200 pumped storage projects will be built in 200 cities and counties, with a target of 270 million kilowatts. The second is to explore diversified industrial applications. Give full play to the supporting role of pumped storage in the development of large bases, and actively promote the development and construction of the integrated water-solar-storage base in the southwest, and the wind-solar storage and clean energy bases in the deserts, Gobi, and deserts of the Northwest. Actively expand the application of small and medium-sized pumped storage in the surrounding areas of cities and in areas rich in new energy. The third is to build a leading industrial system. Build a strong, complete and innovative industrial chain, cultivate a group of backbone enterprises with international competitiveness and influence, and build a world-leading industrial system. The fourth is to do a good job in ecological protection with high standards. Attach great importance to the work of ecological and environmental protection, and create an environment-friendly model project. Fifth, high quality promotes industrial integration. Make the pumped storage power station a model of energy integration development.

As a leader in the field of pumped storage power station construction, China Power Construction Corporation actively fulfills its responsibilities as a central enterprise in the process of developing pumped storage to promote green and low-carbon development and help achieve the “dual carbon” goal. First, perform the functions of resource planning and investigation. Cooperate with relevant parties to carry out the resource survey of pumped storage power stations, select and incubate benchmark projects of the integrated base, and lay a solid foundation for the rapid development of pumped storage. The second is to efficiently promote the survey and design. Among the key projects implemented in the “14th Five-Year Plan”, China Power Construction Corporation has undertaken more than 85% of the project survey and design work. The next step will be to build a pre-project work demonstration system with multi-subject participation and linkage inside and outside the industrial chain, shorten the pre-work cycle on the premise of ensuring the integrity of the technical system and the optimization of technical solutions, and lay the foundation for the accelerated construction of pumped storage. The third is to play a leading role in promoting project construction. On the premise of ensuring project quality and construction safety, accelerate the pace of construction, promote intelligent construction, cultivate a modern talent team, and build a number of high-quality projects with leading management and advanced technology. Fourth, actively explore new models of pumped storage development. Efforts will be made to promote scientific and technological innovation, increase key technical research, and strive to break through technical problems such as intelligent mechanized construction of large underground caverns, dam building and seepage control under complex terrain and geological conditions. Continue to carry out research on the development policies, mechanisms and standards of the pumped storage industry to lead the development of the industry.
