By Yanshihu Lake, machines roar. At the construction site of the 500 kV power transmission and transformation project in Huairou Science City, Beijing, over 30 workers are systematically installing the indoor and outdoor walls of the distribution device building with the cooperation of 12 boom trucks. A 500 kV steel-structured substation is beginning to take shape… Yesterday (23rd), the State Grid Beijing Electric Power Company announced that in the first quarter of 2026, 83 power grid infrastructure projects in the city will fully resume work and production, injecting strong electrical momentum with a “good start” to support the construction of a strong energy nation and help the capital’s “14th Five-Year Plan” achieve high-quality development.

2026 marks the beginning of the “14th Five-Year Plan.” Zou Yu, Director of the Construction Department of State Grid Beijing Electric Power, explained that through vigorously implementing the “3x100” initiatives, peak shaving for summer and winter, livelihood projects, and other power grid infrastructure projects, the company continues to enhance the grid’s complementarity, resilience, and safety. It fully supports major projects and high-tech industries in Beijing, promotes coordinated energy development in the Beijing-Tianjin-Hebei region, and actively serves the electricity needs of residents.

At the construction site of the 500 kV power transmission and transformation project in Huairou Science City, mechanized construction has become a highlight. Workers are using boom trucks, prefabricated component transport and installation machines, and other equipment to carry out construction, greatly improving efficiency while ensuring safety, progress, and green building standards are simultaneously enhanced. “By deeply integrating prefabricated construction with mechanized operations, we ensure project quality and safety while reducing on-site wet work and construction waste, achieving quality improvement, efficiency, and green low-carbon development,” said Wang Tao, project manager of Beijing Electric Power Engineering Co., Ltd.

The Huairou Science City 500 kV transmission and transformation project officially started in March 2024 and is Beijing’s first indoor, steel-structured 500 kV hub substation. “The project resumed on March 17 and is scheduled for completion by the end of this year. After commissioning, it will further improve Beijing’s 500 kV double-ring network structure, effectively meeting the high-reliability power demands of major national scientific research projects in Huairou Science City,” said Ni Haoran, owner project manager of State Grid Beijing Construction Consulting.

It is understood that, centered on Huairou Science City as a core area for national strategic scientific and technological strength, State Grid Beijing Electric Power is accelerating the high-quality construction of supporting power grid projects. In addition to the Huairou Science City 500 kV project, the Luoshan 220 kV, Yongsheng 110 kV, and Chenggezhuang 110 kV transmission projects have also resumed work. Among them, Chenggezhuang Substation, as Beijing’s first fully autonomous and controllable new-generation substation, fully applies domestically produced primary and secondary equipment and materials. After commissioning, it will pioneer demonstration technologies such as one-key control and intelligent patrols, providing a practical platform for the construction of new power systems.

Furthermore, several key grid projects are progressing simultaneously. The capacity expansion of the Fangshan 500 kV substation has fully entered construction, increasing the capacity of the existing two 750 MVA main transformers to 1200 MVA, with completion planned within the year. This will significantly enhance the power supply capacity in southwestern Beijing. The Houjie 220 kV transmission project in Chaoyang District has resumed as scheduled, with on-ground steel structure hoisting underway. It is expected to be completed and put into operation by 2027, providing reliable power support for areas such as the Fourth Embassy District and Jinzhan International Cooperation Service Area, continuously optimizing the power grid layout in the capital’s urban functional zones.

It is also reported that in 2026, State Grid Beijing Electric Power will coordinate the advancement of 111 transmission and transformation projects, including the Fengtai 500 kV and Zhizao 220 kV projects. During the “14th Five-Year Plan,” the company will focus on grid construction as the main theme, accelerate the development of the Jijing UHV DC project, plan to build six external power receiving channels such as the 500 kV Xiheying-Fangshan line, and implement five 500 kV, 74 220 kV, and 231 110 kV transmission projects. The goal is to create a modern power grid system characterized by resilience, green harmony, digital transparency, and autonomous control, ensuring high-quality energy supply to support Beijing’s development as a world-class, harmonious, and livable city.
