湘黔、湘粤、渝黔三项网间电力灵活互济工程通过国家核准

Core Viewpoint - The approval of the Xiangqian, Xiangyue, and Yuchuan flexible interconnection projects will significantly enhance the power transmission capacity between Southern Power Grid and State Grid, with a total investment exceeding 15.6 billion yuan and a maximum transmission capacity of 9 million kilowatts [1][2]. Group 1: Project Details - The three projects are set to start construction by the end of this year and are expected to be completed before the summer peak in 2027 [1]. - The new projects will increase the number of transmission channels between Southern Power Grid and State Grid from 2 to 5, thereby significantly enhancing cross-regional power exchange capabilities [2]. Group 2: Implementation and Coordination - Southern Power Grid has established a multi-disciplinary collaborative mechanism to enhance internal coordination and has formed a joint working group with State Grid to facilitate project planning and execution [3]. - The projects will include the construction of three flexible DC back-to-back converter stations, each with a capacity of 3 million kilowatts, located in Tongren, Guizhou; Chenzhou, Hunan; and Chongqing [4]. Group 3: Benefits and Strategic Importance - The projects will improve power supply security and renewable energy absorption capabilities, particularly benefiting regions with complementary power load characteristics, such as Hunan and Guizhou [10]. - The successful implementation of these projects will provide a solid physical foundation for regular power trading across grid operating areas, enhancing emergency support capabilities during extreme weather events [7][10].
