he construction of Ruoqiang 750kV transmission project in the Tarim Basin of Xinjiang has begun, which will become China’s largest 750kV ultra-high-voltage transmission ring network after its completion.
The 750kV transmission and substation project is a key project of the national “14th Five-Year Plan” power development plan, and after completion, the coverage area will reach 1,080,000 square kilometers, close to one-ninth of China’s land area. The project has a dynamic investment of 4.736 billion yuan, with two new 750 KV substations in Minfeng and Qimo, and the construction of 900 kilometers of 750 KV lines and 1,891 towers, which are scheduled to be completed and put into operation in September 2025.
Xinjiang South Xinjiang new energy reserves, quality, development conditions, wind and water and other clean energy accounted for more than 66% of the total installed capacity. As the backbone of the new power system grid, Huanta 750 KV transmission project is completed, will significantly enhance the southern Xinjiang photovoltaic and other new energy pooling and delivery capacity, driving the development of new energy of 50 million kilowatts in the southern Xinjiang, the maximum power supply capacity of the southern Xinjiang will be increased from 1 million kilowatts to 3 million kilowatts.
Up to now, Xinjiang has 26 750kV substations, with a total transformer capacity of 71 million KVA, 74 750kV lines and a length of 9,814 kilometers, and the Xinjiang power grid has formed a “four-ring network for internal supply and four channels for external transmission” main grid pattern. According to the planning, “14th Five-Year Plan” will form the main grid pattern of “seven ring networks for internal supply and six channels for external transmission”, which will provide a strong impetus for Xinjiang to transform its energy advantages into economic advantages.
