新华全媒+丨2260公里跨越5省份 0.007秒“疆电”点亮山城

Core Viewpoint - The "Xinjiang Power to Chongqing" project, a ±800 kV UHVDC transmission line, has commenced operation, enabling electricity from Xinjiang to reach Chongqing in approximately 0.007 seconds over a distance of 2260 kilometers, marking a significant advancement in China's energy infrastructure [1][2]. Group 1: Project Overview - The project connects Xinjiang's Hami City to Chongqing, passing through Gansu, Shaanxi, and Sichuan, with a total investment of approximately 28.6 billion yuan [2]. - It is part of China's first large-scale renewable energy delivery project from the "Shagou Desert" region, with over 70% of the 14.2 million kW capacity coming from wind, solar, and thermal energy [2]. - The project is expected to deliver over 36 billion kWh of electricity annually, with more than half sourced from renewable energy, effectively replacing about 6 million tons of coal consumption and reducing carbon dioxide emissions by approximately 16 million tons [2]. Group 2: Demand and Benefits - Chongqing's electricity demand has been growing rapidly, with an annual increase of 6%, and is projected to reach an 11% growth rate in 2024 [4]. - The project will provide more green electricity to data centers in Chongqing, helping to lower electricity costs and meet the increasing demand for renewable energy [4]. Group 3: Technical Aspects - The two converter stations are crucial for the project, featuring domestically produced core equipment that stabilizes the intermittent nature of renewable energy, maintaining fluctuations within 5% [6]. - The Chongqing converter station utilizes advanced technology with proprietary intellectual property, enhancing the system's voltage stability and transmission capacity [8]. Group 4: Strategic Importance - The project reflects Xinjiang's ambition to become a national energy resource strategic support base, with significant potential for wind and solar energy development [10]. - Since 2010, Xinjiang has exported over 900 billion kWh of electricity, with renewable energy accounting for about 30% of this total, and the new project will further increase the share of renewable energy in exports to eastern provinces [12].
