Sichuan and Chongqing 1000 kV high -voltage exchange project started construction

Today, the first high -voltage exchange project in the southwestern region of my country -State Grid Co., Ltd. Sichuan -Chongqing 1,000 kV high -voltage exchange project officially started.

As a large state -owned key backbone enterprise related to the national energy security and the lifeblood of the national economy, the State Grid Corporation proposes and insists on cleaning and low -carbon is the basis, energy security is the key, energy independence is fundamental, energy innovation is power, power is power, power innovation is power, and power is power. Energy -saving and efficiency must help, continue to optimize the development of the grid, increase the construction of UHV Power Grid, vigorously promote the construction of a new energy supply and consumption system, and strive to be promoters, pioneers, and leaders of energy cleaning and low -carbon transformation.

The Sichuan -Chongqing special high -voltage exchange project, which was officially constructed this time, is a major project of the National State Corporation's decision -making and deployment of the Party Central Committee and the State Council, and implementing major national strategies for the Shuangcheng Economic Circle in Chengdu -Chongqing. The starting project of the southwest special high -voltage exchange backbone grid. The project newly built four special high -voltage transformer stations in Ganzi, Tianfu South, Chengdu Donghe Chongqing Tongliang, with a substation capacity of 24 million kV. The newly -built double -back high -voltage line is 658 kilometers, with a total investment of 28.8 billion yuan. It is planned to be put into operation before the peak of 2025.

At the same time, in order to optimize the structure of the regional grid grid, enhance the power protection capacity of Sichuan Province, support the development of large -scale clean energy, and effectively undertake the landing power of the Sichuan Province, the National Grid and Sichuan Province have also launched a new round of major power grid engineering projects. Construction, 22 major power grid projects such as Panxi Optimization, Salt Source Reconstruction, Leshan South, and Deyang South, etc., will add 13 million kichesis, the total length of the new line is 1410 kilometers. All monthly is put into operation.

During the "Fourteenth Five -Year Plan" period, with the accelerated construction of the Chengdu -Chongqing Shuangcheng economic circle, Sichuan -Chongqing's electricity demand will grow rapidly. It is expected that the largest load of Sichuan and Chongqing will exceed 89 million kilowatts and 35.5 million kilowatts in 2025, respectively, respectively, respectively, respectively, respectively, respectively, respectively. 10.5%, 44.31%. Sichuan -Chongqing high -voltage project is a high -speed road connecting Sichuan and Chongqing power supply and load centers. After completion important meaning.

In October 2021, the Government of Sichuan and Chongfeng issued the "Outline of the Construction Planning of the Shuangcheng Economic Circle of Chengdu -Chongqing District", and in March 2022, the "Sichuan -Chongqing Power Grid Integrated Construction Plan" was issued, which proposed to optimize the allocation of Sichuan -Chongqing power resources to promote the promotion Sichuan -Chongqing Grid has been upgraded to promote interconnection. At present, the backbone grid of the Sichuan -Chongqing Grid is 500 kV Grid, which is connected to East China, Central and Northwest Power Grid through multiple high -voltage and 500 kV transmission channels. After the completion of the Sichuan -Chongqing special high -voltage project, the main grid voltage level of the Southwest Power Grid of my country will be increased from 500 kV to 1,000 kV. It can effectively meet the needs of the diversified power development of the power supply. It can effectively undertake the power from the northwest, Tibet and other places, and greatly improve The overall power guarantee capabilities of the Shuangcheng Economic Circle in Chengdu -Chongqing area laid the foundation for the construction of a stronger and perfect UHV backbone mesh.
