十五五电网投资超万亿，锂电迎系统级增量

Core Viewpoint - The article discusses the significant expansion of China's power grid, which is expected to reshape the lithium battery demand structure due to a massive investment plan by the State Grid Corporation, amounting to 4 trillion yuan during the 14th Five-Year Plan, marking a 40% increase from the previous plan [1][3]. Investment and Development Goals - The State Grid's investment plan aligns with the 1710 document, which sets clear targets for the development of a new type of power grid by 2030, aiming for renewable energy to account for approximately 30% of total power generation and to support over 40 million charging facilities [2][4]. - The total investment in China's power grid during the 15th Five-Year Plan is projected to exceed 5 trillion yuan, with significant investments in the southern power grid as well [3]. Challenges in Renewable Energy Integration - By 2025, the installed capacity of renewable energy is expected to approach 50%, but the actual power generation from these sources is projected to be less than 25%, indicating a significant gap due to the grid's inability to accommodate new energy sources [4][5]. - The increasing cost of integrating renewable energy into the grid is highlighted, with estimates suggesting that for every 1% increase in renewable energy penetration, system costs rise by approximately 0.01 yuan per kilowatt-hour [6]. Structural Reforms in the Power Grid - The 1710 document proposes a transformative approach to the power grid, emphasizing a collaborative structure involving main, distribution, and micro grids, which aims to enhance the grid's capacity to integrate renewable energy [10][11]. - Key development goals include improving cross-regional transmission capabilities and optimizing the grid structure to support a significant increase in renewable energy integration by 2030 [11][12]. Focus Areas for Future Investments - Future investments will primarily target core technology areas such as distributed independent energy storage and smart microgrid solutions, which are essential for enhancing the grid's capacity to accept renewable energy [15][20]. - The article emphasizes the importance of advanced technologies like grid-forming inverters and energy storage systems to address dynamic stability issues caused by high levels of renewable energy integration [18][23]. Conclusion - The 1710 document is positioned as a guiding framework for the next decade of power grid development in China, aiming to facilitate a transition towards a new energy system that can effectively support high levels of renewable energy integration [24].
