Core Viewpoint - The "Jiangdian into Chongqing" project, part of China's "14th Five-Year Plan," has successfully commenced power transmission, utilizing over 70% renewable energy from a 14.2 million kilowatt power source [1][6]. Group 1: Project Overview - The "Jiangdian into Chongqing" project connects five provinces and municipalities, spanning 2,260 kilometers, and has achieved operational status in under two years, setting a record for the fastest construction of a high-voltage transmission line over 2,000 kilometers in China [2][4]. - The project leverages unique wind and solar resources in the arid regions of Xinjiang, with the local area currently utilizing less than 5% of its renewable energy potential [6][15]. Group 2: Technical Challenges and Solutions - The construction faced significant challenges due to complex terrains, including snow-capped mountains and deserts, with winter temperatures in Xinjiang dropping to -30 degrees Celsius [5]. - To ensure stability in high-wind areas, the construction team reinforced transmission towers in regions with wind speeds reaching level 10, enhancing the safety of the power lines [5]. Group 3: Environmental Impact - The project is expected to deliver 36 billion kilowatt-hours of electricity annually to Chongqing, with a clean energy ratio of at least 50%, resulting in a reduction of 16.5 million tons of CO2 emissions each year, equivalent to planting 900 million trees [7][15]. Group 4: Technological Aspects - The project employs a ±800 kV high-voltage direct current (HVDC) system, allowing electricity to travel from Xinjiang to Chongqing in just 7 milliseconds, significantly improving the cross-regional consumption of clean energy [8][10]. - The Chongqing converter station, covering 27 hectares, utilizes advanced technology for monitoring and maintaining the core components, ensuring efficient conversion from direct current to alternating current for household use [12][14]. Group 5: Economic Significance - The "Jiangdian into Chongqing" project enhances the energy structure of Chongqing, providing enough electricity for 10 million households annually, and supports the economic development of both Xinjiang and Chongqing [15].
