As the proportion of new energy sources such as wind energy and solar energy in my country's energy system continues to increase, energy storage technologies and industries closely related to the development of new energy sources have also attracted much attention. Since 2022, provinces and cities have accelerated the implementation of energy storage projects, and more than 20 provinces have clarified the allocation and storage ratio of supporting energy storage equipment.

Accelerate the layout of energy storage construction in many places

In Changxing, Zhejiang, the construction of a new energy battery production base project with a total investment of 6.7 billion yuan officially started. The project plans to build a world-leading energy storage system around new energy raw materials such as lithium iron phosphate and ternary materials. Chen Xuefeng, deputy director of the Development and Reform Bureau of Changxing County, Zhejiang Province: During the "13th Five-Year Plan" period, we have already begun to plan and deploy an energy development system that integrates "source, network, load, storage and sales". As an important link in the energy storage industry, we support market players. In particular, leading enterprises should strengthen product technology research and development. For leading enterprises with relatively mature technologies, we attract Changxing to invest in the development of the energy storage industry.

In Jinan, Shandong, China's first 100-megawatt decentralized control energy storage power station was officially put into operation. It can charge 212,000 kWh per charge, which can meet the power consumption of 1,000 households for a month. Wen Ziqiang, engineer of the 100-megawatt distributed control energy storage power station in Jinan: Our project currently absorbs the surplus new energy power in Shandong Province, which can be charged and discharged twice a day, and can absorb 400,000 kWh of electricity, and then through the demand of the grid, It is released in real time for users to use.

Hunan Province has established a "new energy + energy storage" mechanism, and strives to build an electrochemical energy storage power station of more than 1.5 million kWh by 2023.

Ningxia proposed that the energy storage allocation ratio of new energy projects should not be less than 10%, and the continuous energy storage time should be more than 2 hours.

Dai Jianfeng, director of the Technology Innovation and Industrial Planning Center of the General Electric Power Planning and Design Institute: At present, we have entered the early stage of commercial application from the laboratory stage. By the end of 2021, the scale of China's new energy storage has exceeded 3 million kilowatts.

The "Guiding Opinions on Accelerating the Development of New Energy Storage" issued by the National Development and Reform Commission and the Energy Administration proposed that by 2025, the new energy storage will be transformed from the initial stage of commercialization to large-scale development, with an installed capacity of more than 30 million kilowatts, and by 2030 , to realize the comprehensive market-oriented development of new energy storage.

Chen Haisheng, Director of the Energy Storage Special Committee of the China Energy Research Association: At present, our overall installed capacity of energy storage is about 2% of the total installed capacity of our system. Around 2050, it should account for 10% to 15% of the total installed capacity. There is still a huge space for our market demand.
