多项网间电力灵活互济工程获核准

Core Viewpoint - The approval of the Xiangqian, Xiangyue, and Yuchuan flexible interconnection power projects will significantly enhance the power transmission capacity between the Southern Power Grid and the State Grid, with a total investment exceeding 15.6 billion yuan and a maximum transmission capacity of 9 million kilowatts by 2027 [1][2]. Group 1 - The three projects are set to start construction by the end of this year and are expected to be operational before the summer peak in 2027, increasing the number of transmission channels between the Southern Power Grid and the State Grid from 2 to 5 [1]. - Each of the three projects will involve the construction of a 3 million kilowatt flexible DC back-to-back converter station in Guizhou, Hunan, and Chongqing, along with related line construction to enhance interconnectivity [1][2]. - The projects will provide a solid physical foundation for normalized electricity trading between interconnected regions, supporting high-quality economic and social development and green energy demands [1]. Group 2 - The Xiangqian project will enable peak-shaving interconnection between Hunan, which experiences high electricity load in summer, and Guizhou, which has a "winter high, summer low" load characteristic, thus enhancing power supply security and renewable energy absorption [2]. - In case of extreme weather events, such as high temperatures or severe cold, the Xiangqian project will allow for emergency power support from the opposite side, significantly improving the grid's disaster response capability [2]. - The Southern Power Grid and the State Grid will enhance collaboration and resource investment to ensure high-quality construction and operation of the projects, accelerating the development of a new energy system and power structure [2].
