国家能源局发布：我国新型储能装机规模占全球总装机比例超40%

Core Viewpoint - The rapid development of new energy storage in China is significantly enhancing the role of the new power system, promoting renewable energy utilization, and improving the safety and stability of the power system [1][2]. Group 1: Development Status - As of the end of 2024, China has built and put into operation new energy storage capacity of 73.76 million kilowatts (168 million kilowatt-hours), accounting for over 40% of the global installed capacity [1]. - The policy framework for new energy storage has been progressively established since the 14th Five-Year Plan, with multiple policy documents released to guide scientific development and improve the electricity market mechanism [1]. Group 2: Application and Impact - The application effects of new energy storage are becoming increasingly evident, with the average equivalent utilization hours exceeding 1,000 hours in provinces such as Zhejiang, Jiangsu, Chongqing, and Xinjiang in 2024, serving as a crucial means for renewable energy consumption [2]. - During peak summer periods, new energy storage has played a vital role in ensuring electricity supply during peak demand times, functioning effectively as a "super battery" [2]. Group 3: Technological Innovation - In 2024, the National Energy Administration announced 56 pilot projects for new energy storage, covering over ten technological routes, with several projects representing the first engineering applications in the country [2]. - Twelve new energy storage projects were selected as part of the fourth batch of major technological equipment in the energy sector, providing application scenarios for the implementation of first-of-a-kind equipment [2]. Group 4: Standardization - In 2024, more than 20 electrochemical energy storage standards were published and implemented, with multiple standards initiated, covering various aspects such as planning, grid connection, operation control, maintenance testing, and post-evaluation [2].
