Core Viewpoint - The Hami to Chongqing ±800 kV UHVDC project is a significant infrastructure initiative aimed at transmitting clean energy from Xinjiang to central and western China, enhancing energy security and promoting green energy utilization [1][6]. Group 1: Project Overview - The Hami to Chongqing UHVDC project spans approximately 2,290 kilometers, connecting five provinces: Xinjiang, Gansu, Shaanxi, Sichuan, and Chongqing [1]. - The project is expected to deliver 36 billion kilowatt-hours of electricity annually, with over 18 billion kilowatt-hours sourced from wind and solar power, effectively replacing 6 million tons of coal and reducing carbon dioxide emissions by 16.5 million tons [2]. Group 2: Renewable Energy Contribution - The project boasts a record of over 70% renewable energy in its installed capacity, with 10.2 million kilowatts out of a total of 14.2 million kilowatts coming from wind, solar, and thermal sources [2]. - The natural time zone complementarity between Xinjiang and Chongqing allows for efficient energy supply during peak demand periods in Chongqing [2]. Group 3: Technological Innovations - The project employs advanced technologies such as the dual-arm support technology, enhancing wind resistance by 50% and doubling construction efficiency [3]. - The use of high-strength aluminum alloy components and a unique aerial transport system has significantly improved the project's logistics and construction timelines [3]. Group 4: Economic Impact - The Hami UHVDC project has an investment of 28.6 billion yuan, stimulating over 100 billion yuan in upstream and downstream investments and creating more than 40,000 jobs [5]. - The project has catalyzed the growth of a complete industrial chain in renewable energy equipment manufacturing, contributing to a 20 billion yuan increase in the value of the power transmission and transformation equipment manufacturing sector [5]. Group 5: Future Developments - Following the completion of the Hami to Chongqing project, plans are in place to accelerate the construction of additional UHVDC and AC transmission lines to further leverage Xinjiang's resource advantages [6].

Core Insights - The Hami to Chongqing ±800 kV UHVDC transmission project is set to be completed and put into operation in May, significantly enhancing electricity supply from Xinjiang to Chongqing [1][2] Group 1: Project Overview - The project involves the construction of a high-voltage direct current transmission line that will transport over 36 billion kilowatt-hours of electricity annually from Xinjiang to Chongqing [2] - The project is expected to promote the sustainable development of the western region's economy and society by leveraging Xinjiang's energy resources [2] Group 2: Technological Innovation - The use of drones for high-altitude monitoring and inspection has significantly reduced labor costs and enhanced safety for workers in harsh weather conditions [2] - Drones have improved inspection efficiency, allowing for rapid completion of large-scale inspections compared to traditional methods, increasing efficiency several times over [2] Group 3: Inspection Process - The drone team successfully inspected 163 iron towers and a 97.61-kilometer section of the transmission line, identifying and documenting issues for necessary rectifications [2] - The integration of drone technology into the inspection process has provided critical data and insights for the project's quality assurance [2]
