Core Viewpoint - The Ningxia-Hunan ±800 kV UHVDC project, known as "Ning Dian Ru Xiang," has been put into operation, marking a significant step in optimizing the distribution of clean energy in China [1] Group 1: Project Overview - The project is China's first approved UHV transmission channel primarily for transporting renewable energy from the "Shagehuang" wind and solar power base [1] - It has a rated voltage of ±800 kV and a rated capacity of 8 million kW [1] - The transmission line spans 1,616 kilometers, starting from Zhongning Converter Station in Ningxia and ending at Hengyang Converter Station in Hunan, passing through Gansu, Shaanxi, Chongqing, and Hubei [1] Group 2: Significance - The project serves as a crucial link between the abundant renewable energy resources in the western region and the load centers in central China [1] - It plays an important role in enhancing the power supply security and facilitating large-scale optimization of clean energy distribution [1]

Core Viewpoint - The Hami-Chongqing ±800 kV UHVDC project has been put into operation, significantly enhancing the electricity transmission capacity from Xinjiang to Chongqing, with a distance of 2260 kilometers covered in approximately 0.007 seconds [1][2]. Group 1: Energy Supply and Demand - The electricity demand in Chongqing has been growing at an annual rate of 6%, with a projected growth rate of 11% in 2024, while Xinjiang is rich in energy resources, making it a crucial source for electricity transmission to the east [2]. - The project includes 14.2 million kW of power sources, with over 10.2 million kW coming from wind, solar, and thermal energy, resulting in a renewable energy installation ratio exceeding 70% [2]. Group 2: Technological Innovations - The project faced challenges such as harsh environmental conditions and complex construction logistics, but innovative technologies were employed to enhance construction efficiency and address difficulties [3]. - The ±800 kV converter station in Hami features 14 converters, each with a capacity of approximately 400,000 kW, achieving over 90% localization of equipment [3]. Group 3: Economic Impact - The Hami-Chongqing project has stimulated over 100 billion yuan in upstream and downstream investments, creating more than 10,000 jobs directly related to the project and over 30,000 jobs in related sectors such as equipment manufacturing and energy services [4]. - Hami has developed a wind power equipment manufacturing base, with local supply rates exceeding 70%, significantly boosting the output value of the power transmission and transformation equipment manufacturing industry by 20 billion yuan [4].
