Core Viewpoint - The ±1100 kV Changji-Guquan UHVDC project is a landmark engineering achievement in the global power development history, facilitating the transmission of electricity from Xinjiang to East China, significantly enhancing energy supply reliability and promoting economic growth in the region [3][5]. Group 1: Project Overview - The Changji-Guquan UHVDC project spans 3,293 kilometers, connecting Xinjiang to Anhui province, and was officially put into operation on September 26, 2019 [3]. - It is recognized as the highest voltage level, largest transmission capacity, longest transmission distance, and highest technical standard UHVDC project in the world [3]. Group 2: Economic and Environmental Impact - The project can deliver 66 billion kWh of electricity annually to East China, sufficient to power 400 million 30-watt light bulbs and meet the electricity needs of 50 million households [3]. - It reduces coal transportation by 30.24 million tons per year and decreases emissions of dust by 24,000 tons, sulfur dioxide by 149,000 tons, and nitrogen oxides by 157,000 tons [3]. Group 3: Resource and Development Potential - Xinjiang has abundant energy resources, with proven coal reserves of 2.136 billion tons, making it suitable for local power generation [5]. - The region is one of the nine large wind power bases planned by the state, with a potential wind power capacity exceeding 200 million kW, indicating significant renewable energy development potential [5].
