National Grid(US:NGG) 中关村储能产业技术联盟·2025-10-11 10:44Core Viewpoint - Jiangsu has established the most comprehensive and resource-rich regional energy storage peak regulation system in China, serving as a model for the construction of a new power system nationwide. This development coincides with the release of the "Special Action Plan for Large-Scale Construction of New Energy Storage (2025-2027)" which aims for a national installed capacity of over 180 million kilowatts by 2027, potentially driving direct investment of approximately 250 billion yuan [1][3]. Group 1 - Jiangsu's power grid has surpassed a maximum load of 156 million kilowatts, with renewable energy generation capacity exceeding 100 million kilowatts. The fluctuation in solar power generation creates significant peak regulation pressure on the grid, posing challenges to its safe operation [3][4]. - The newly established regional energy storage peak regulation system is designed to address these challenges effectively, acting as a "golden key" to enhance grid stability [3][4]. - The system integrates three core capabilities: centralized utilization of over 7.6 million kilowatts of new energy storage, scientific allocation of 3.73 million kilowatts of pumped storage, and innovative access to mobile energy storage resources from electric vehicles [4][6]. Group 2 - The system's effectiveness is highlighted by its ability to aggregate dispersed energy storage resources across the province, enabling flexible control. Notably, it innovatively incorporates electric vehicles into the scheduling process, guiding them to participate in peak regulation during idle times [6][7]. - During the peak summer period this year, the system demonstrated impressive performance, utilizing energy storage resources over 14,000 times, with total charge and discharge exceeding 25 billion kilowatt-hours and a maximum peak regulation capacity exceeding 10 million kilowatts [7][9]. - The intelligent scheduling platform developed by State Grid Jiangsu Power enables real-time assessment of grid fluctuations, generating optimal charge and discharge control strategies to ensure efficient coordination and cluster control of various energy storage resources [7][9]. Group 3 - To effectively utilize the energy storage system for peak regulation, operational challenges must be addressed, including the need for comprehensive forecasting of power generation from thermal, wind, and solar sources, as well as external power supply [9][10]. - The national landscape shows that various regions, including Inner Mongolia, Shandong, and Xinjiang, have initiated large-scale centralized energy storage calls, each exceeding 5 million kilowatts, to enhance the flexibility and efficiency of energy storage resources [10].
