Core Points - The construction of key power projects in Xinjiang has entered a critical phase, injecting strong electrical momentum for high-quality development in the region [1] - The "Ruoqiang-Lingyang 750 kV Transmission and Transformation Project" has a dynamic investment of 3.13 billion yuan and is expected to be operational in the first half of 2027, enhancing the power supply quality in southern Xinjiang and Qinghai [2] - The "Tokkuzhan 750 kV Transmission and Transformation Project" has a total investment of 3 billion yuan and is planned to be completed by 2028, forming a main network framework in the Turpan region [2] - Both projects face complex challenges, including the need to traverse high-altitude areas and remote regions, with innovative solutions such as cableway construction being implemented [3] - Additional projects, including the "Ili Zhongmei Two Joint Ventures" power plant and the expansion of the "Yandun 750 kV Substation," are also entering the full construction phase, further strengthening Xinjiang's power grid [3] - Xinjiang's ultra-high voltage power grid development is set to upgrade continuously, with plans for 41 new and ongoing ultra-high voltage projects in 2025 [3]

Core Viewpoint - The successful commissioning of the 750 kV transmission and transformation project from Shaanxi to Gansu marks the completion of Gansu's 20th and 21st inter-provincial connection lines, enhancing the province's power transmission capacity and supporting clean energy consumption in the northwest region [1][2]. Group 1 - The project starts from the 750 kV Xizhou substation in Shaanxi and ends at the 750 kV Quzi substation in Gansu, with a total length of 144 kilometers and the construction of two 750 kV double-circuit lines [2]. - The newly commissioned equipment includes two 210 MVar high-voltage parallel reactors and four 750 kV circuit breakers, significantly improving the operational reliability and flexibility of the Qinyang converter station [2][4]. - Gansu's power grid has established two ultra-high voltage transmission channels, with plans to accelerate the construction of additional external transmission lines to enhance energy resource advantages [7]. Group 2 - The construction faced complex terrain and harsh environmental conditions, leading to the adoption of mechanized construction methods to maximize efficiency and ensure timely completion [4]. - The project has already facilitated the transmission of 26.95 billion kWh of electricity to 26 provinces, indicating its significant role in the national power grid [7]. - Gansu aims to plan for 2-3 additional external transmission channels to be included in national planning, further transforming energy resource advantages into economic benefits [7].
