On August 30, 2024, State Grid Shaanxi Electric Power Co., Ltd. held a grand mobilization meeting for the commencement of the 750 kV third channel power transmission and transformation project from northern Shaanxi to Guanzhong, which marked the official construction stage of the core projects in the energy and power field during the 14th Five-Year Plan period in Shaanxi Province. The project is not only a key engine to promote the high-quality economic and social development of the province, but also a landmark project for green transformation and improvement of people's livelihood, aiming to strengthen the smart grid architecture, actively respond to the rapid momentum of new energy development, and strengthen the backbone structure of Shaanxi's power network.

In today's global wave of green, low-carbon, intelligent and sustainable development, China is leading profound changes in the energy sector and is committed to improving the security and green level of energy supply. Shaanxi, as a major energy province, is experiencing a dual drive mode from traditional energy and new energy, especially in northern Shaanxi, where traditional resources such as coal, oil and gas and clean energy such as wind power and photovoltaic work together, showing unprecedented vitality. In the face of the urgent requirements of the dual carbon goal, Shaanxi Power Grid is shouldering the important task of energy structure transformation while ensuring power supply.

As a milestone project in the history of Shaanxi power grid construction, the 750 kV third channel project from northern Shaanxi to Guanzhong has a grand scale, and the investment and line length have reached the highest in history. The project starts from the Shuofang substation in Shenmu City, Yulin, spans thousands of miles, and goes directly to the Bailuyuan substation in Lantian County, Xi'an, with new and expanded substations along the way, and laying ultra-long-distance high-voltage lines. The implementation of this super project will greatly enhance the power transmission capacity from northern Shaanxi to Guanzhong, provide a solid backing for the power demand of Guanzhong and southern Shaanxi, and is expected to increase the annual power transmission capacity by 17 billion kilowatt hours, significantly promoting inter-regional energy mutual assistance.

In the construction of the project, State Grid Shaanxi Electric Power adheres to the concept of innovation-led and green development, and strives to build an efficient, environmentally friendly and intelligent modern power grid by relying on advanced technology and intelligent management methods. Through the use of advanced technologies such as compact design and multi-loop erection of the same tower, the transmission efficiency is effectively improved and the land occupation is reduced. At the same time, adhere to the principle of green and low-carbon construction, widely adopt mechanized operations, and reduce the impact on the ecological environment; With the help of big data and artificial intelligence technology, the intelligent and accurate project management is realized to ensure the safe, high-quality and efficient progress of the project.

In addition, the project will also have a far-reaching impact on the development of new energy in northern Shaanxi, help the construction of energy demonstration zones such as Yulin and Yan'an, and promote the optimization and upgrading of the regional energy structure by increasing the supply of clean energy, reducing coal consumption and carbon dioxide emissions. At the same time, the project will also drive the investment and development of upstream and downstream enterprises in the power industry chain, inject new vitality into the strategic emerging industries in Shaanxi Province, and provide strong support for the high-quality development of the province.Editor/Jiang Mingyue
