新增54GWh！国家能源局发布储能重要数据

Core Viewpoint - The article discusses the development and growth of new energy storage in China, highlighting significant increases in installed capacity and utilization hours, as well as regional contributions to this growth [1][2][3]. Summary by Sections New Energy Storage Capacity - As of mid-2025, China's new energy storage capacity reached 94.91 million kilowatts (22.2 billion kilowatt-hours), marking a 29% increase from the end of 2024 [2]. - The newly added capacity in the first half of 2025 was 21.15 million kilowatts (54 GWh) compared to the end of 2024 [3]. Regional Distribution - Inner Mongolia and Xinjiang each exceeded 10 million kilowatts in installed capacity, while Shandong, Jiangsu, and Ningxia surpassed 5 million kilowatts [6]. - The North China, Northwest, and Southern regions accounted for over 80% of the new installed capacity, with North China and Northwest regions holding 29.7% and 25.7% respectively [8]. Utilization and Performance - The equivalent utilization hours for new energy storage increased by over 100 hours to approximately 570 hours in the first half of 2025 [13]. - Provinces like Zhejiang, Guangdong, Gansu, and Xinjiang reported utilization hours exceeding 600 hours, indicating improved performance in energy regulation [16]. Contribution to Power Supply - During the high-temperature period in July, new energy storage played a crucial role in ensuring power supply, with peak discharge capacities reaching 7.14 million kilowatts in Jiangsu, 8.04 million kilowatts in Shandong, and 4.74 million kilowatts in Yunnan [17]. Future Outlook - The year 2025 is identified as a pivotal year for the new energy storage sector, coinciding with the conclusion of the 14th Five-Year Plan and the initiation of the 15th Five-Year Plan, emphasizing technological innovation and high-quality development [18].
