93座电站参与！江苏完成全国最大规模新型储能集中调用

Core Viewpoint - The article highlights the significant role of new energy storage systems in managing peak electricity demand in Jiangsu, China, particularly during high-temperature periods, showcasing a record peak load and the largest scale of centralized energy storage deployment to date [1]. Group 1: Peak Electricity Demand - As of July 7, Jiangsu's electricity grid reached a record peak load of 152 million kilowatts, marking the third time this year it has set a historical record [1]. - On July 6, 93 new energy storage stations collectively discharged a maximum power of 7.14 million kilowatts during peak evening hours, demonstrating the effectiveness of centralized energy storage [1]. Group 2: Energy Storage Capacity and Utilization - The total capacity of energy storage projects in Jiangsu is 7.616 million kilowatts, ranking fourth in the country, and includes various forms such as electrochemical storage and compressed air storage [2]. - The centralized discharge during the peak on July 6 involved 64 grid-side and 29 source-side energy storage stations, with a total participation capacity of 7.248 million kilowatts, achieving a record scale of centralized utilization with a year-on-year increase of 56.9% [1][2]. Group 3: Operational Strategy - The timing of charging and discharging for energy storage systems is crucial, as it must align with urban electricity demand while also maximizing revenue for storage projects [2]. - The energy storage systems serve as "spatial and temporal regulators," with peak electricity demand in southern Jiangsu occurring during the day and in northern Jiangsu at night, allowing for strategic energy management [2].
