CNESA年度重磅 | 2025储能产业盘点——深水笃行，于波动中韧性生长

Core Viewpoint - The year 2025 marks a critical transition for China's energy storage industry, shifting from large-scale development to market-oriented growth, with significant advancements in technology and policy frameworks [2][3][44]. Group 1: Scale Leap - By the end of 2025, China's cumulative installed power storage capacity reached 213.3 GW, a year-on-year increase of 54%, with new energy storage accounting for 144.7 GW, over two-thirds of the total [5][6]. - The new energy storage projects added in 2025 amounted to 66.43 GW / 189.48 GWh, representing a year-on-year growth of 52% / 73% [5]. - The trend towards larger projects is evident, with the number of planned or under-construction hundred-megawatt stations doubling compared to the same period in 2024 [5]. Group 2: Mechanism Restructuring - The industry transitioned from policy-driven growth to market-driven dynamics, with the establishment of a comprehensive electricity market system [7][10]. - The average peak-to-valley price difference for time-of-use electricity across 32 regions decreased to 0.616 yuan/kWh, a 9.4% year-on-year reduction [8]. - Capacity pricing policies were accelerated, with regions like Inner Mongolia and Gansu leading the way in implementing capacity compensation mechanisms [9][10]. Group 3: Scenario Resonance - The cumulative installed capacity of grid-side storage reached 87.0 GW by the end of 2025, accounting for 60.1% of the total, with an average project duration of nearly 3 hours [11][12]. - The generation-side storage capacity reached 46.2 GW, focusing on wind and solar integration, and playing a crucial role in local power balance [13]. - User-side storage projects are increasingly large-scale, with five projects exceeding 100 MW, primarily in high-energy-consuming industries [14]. Group 4: Cycle Refinement - The prices of core materials in the energy storage industry saw a significant increase, with lithium carbonate prices rebounding from 60,000 yuan/ton to 120,000 yuan/ton, a nearly 100% increase [16]. - The production capacity of large-capacity cells is on the rise, while smaller cell production is gradually shrinking, indicating a structural optimization in the industry [19]. Group 5: Global Competition - The domestic market is characterized by a concentration of leading enterprises, with major players like CRRC Zhuzhou and BYD leading the bidding landscape [20][21]. - The global energy storage market is witnessing growth in emerging markets, particularly in the Middle East and Latin America, driven by local supply and demand dynamics [24][25]. Group 6: Innovation Advancement - The year 2025 marked the mass production of 500Ah+ large cells, with several companies achieving GWh-level production capacity [26]. - Solid-state battery technology is advancing, with half-solid batteries seeing increased application, while full-solid batteries are expected to reach market acceptance by 2035 [27]. - AI technology is becoming a core driver for asset value enhancement, optimizing market strategies and improving operational efficiency [31]. Group 7: Standard Foundation - New safety standards have been established, including GB 44240-2024 for mandatory safety testing, enhancing the credibility of energy storage systems [33]. Group 8: Capital Empowerment - The CNESA energy storage index rose by 41.7% in 2025, outperforming major stock indices, reflecting the high prosperity of the energy storage industry [34]. - The primary market for energy storage saw 102 financing events totaling 13.4 billion yuan, with a focus on hard technology innovation and application scenarios [35][36].
