近日，鲁苏背靠背联网工程正式获得国家发展改革委核准批复。

Recently, the Lu-Su back-to-back interconnection project has officially received approval and approval from the National Development and Reform Commission.

工程建成投运后，将增强山东、江苏两省以及华北、华东区域电网互联互通水平，提高电力灵活互济、余缺互补和紧急支援能力，对保障电力安全可靠供应、支撑全国统一电力市场建设具有重要意义。

After the project is completed and put into operation, it will enhance the interconnection level of the power grids in Shandong and Jiangsu provinces, as well as in the North China and East China regions. It will improve the flexibility of power mutual assistance, the balance of supply and demand, and the emergency support capabilities. This is of great significance for ensuring the safe and reliable supply of electricity and supporting the construction of the national unified power market.

鲁苏背靠背联网工程将在山东省临沂市兰陵县新建1座±260千伏直流换流站，换流容量300万千瓦，是山东电网首座柔性直流换流站；新建换流站至山东兰陵变电站、江苏姚湖变电站各2回500千伏线路，总长2×87.9千米。该工程计划于2026年三季度开工，2028年建成投运。

The Lu-Su back-to-back grid connection project will build a ±260-kilovolt DC converter station in Lanling County, Linyi City, Shandong Province. The converter capacity is 3 million kilowatts, making it the first flexible DC converter station in the Shandong power grid. Two 500-kilovolt lines will be newly constructed from the new converter station to the Linyi County Substation in Shandong and the Yaohu Substation in Jiangsu, with a total length of 2×87.9 kilometers. The project is scheduled to start in the third quarter of 2026 and be completed and put into operation in 2028.
