Core Viewpoint - The Aba-Chengdu East UHV AC Transmission Project is progressing rapidly, with the first segment successfully completed, marking a significant milestone in the construction of this critical infrastructure for clean energy transmission in the Sichuan region [1][3]. Group 1: Project Progress - The first segment of the project, approximately 85 kilometers long, has successfully connected, featuring 176 new transmission towers [3]. - Construction teams are utilizing advanced techniques and equipment to overcome challenging terrain and weather conditions, with nearly 90% of tower assembly completed and over 40% of wire installation achieved [3][4]. - The project involves over 3,000 workers across 16 segments, emphasizing the importance of maximizing the winter construction window for efficient progress [3]. Group 2: Project Significance - The Aba-Chengdu East UHV project, spanning 734.8 kilometers, is designed to enhance the transmission capacity of the Aba corridor by more than double, meeting the integration needs of hydropower and renewable energy sources [4]. - Scheduled for completion by the end of 2026, the project aims to support the economic development of the Chengdu-Chongqing economic circle by delivering clean electricity to major load centers [4].

Core Viewpoint - The Sichuan Aba-Chengdu East 1000 kV UHVAC transmission project has successfully completed its first segment, marking a significant milestone in the construction of a major clean energy transmission line in Sichuan province [1][6]. Group 1: Project Overview - The project spans a total length of 734.8 kilometers, connecting the Aba 1000 kV substation to the Chengdu East 1000 kV substation, and traverses four cities and eleven counties [6]. - The first segment, which has been completed, is approximately 85 kilometers long, starting from Mianyang Santai County and ending in Deyang Zhongjiang County, requiring the construction of 176 new transmission towers [3][6]. Group 2: Construction Progress - Currently, over 3,000 builders are engaged in the construction across 16 segments, with a completion rate of nearly 90% for tower assembly and over 40% for wire installation [4][6]. - The project employs advanced technologies such as construction safety networks and visual tensioning equipment to ensure efficient and safe progress amid challenging geological and climatic conditions [3][4]. Group 3: Strategic Importance - The project is positioned as a core carrier for the high-quality development of clean energy in western Sichuan, with an expected operational date by the end of 2026 [6]. - Once operational, the transmission capacity of the Aba corridor will more than double, effectively meeting the grid connection needs of the Aba hydropower cluster and renewable energy bases, ensuring stable delivery of clean electricity to load centers like Chengdu [6].
