支撑今夏用电负荷三创新高

Core Insights - The State Grid of Jiangsu has reported a record high electricity load of 152 million kilowatts as of July 7, driven by sustained high temperatures, marking the third time this year that the record has been broken [1] - On July 6, 93 new energy storage stations in Jiangsu collectively discharged a maximum power of 7.14 million kilowatts during peak evening electricity demand, representing the largest scale of centralized new energy storage utilization in China [1] - The centralized discharge of new energy storage has increased by 56.9% year-on-year compared to last summer's peak discharge of 4.55 million kilowatts [1] Group 1 - New energy storage is referred to as a "super battery," providing peak load regulation during high electricity demand and assisting in renewable energy consumption during low demand periods [1] - The total capacity involved in the centralized discharge was 7.248 million kilowatts, with the actual maximum utilization reaching 7.14 million kilowatts, capable of meeting the electricity needs of approximately 48 million households for one hour [1] - Jiangsu's new energy storage projects are strategically located, with a total installed capacity of 7.616 million kilowatts, ranking fourth in the country, and include various forms such as electrochemical storage and compressed air storage [2] Group 2 - The timing of charging and discharging for energy storage systems requires careful consideration to maximize profitability while meeting urban electricity demands [2] - The peak electricity demand in southern Jiangsu occurs during the day, while northern Jiangsu experiences peak demand at night, allowing energy storage to act as a "spatial-temporal regulator" [2]
