[The world's first 500 kV economical high voltage AC current limiter] A few days ago, the world's first 500kV/90kA economical high-voltage AC current limiter developed by China Xidian Group successfully completed the manual short-circuit test and was successfully put into operation on the Shun-Guang-A line of the 500kV Guangnan Station. The successful operation of the project has filled the domestic economical AC ultra-large short-circuit current suppression technology gap, provided an economical and reliable solution for the suppression of high-voltage AC short-circuit current, and provided a strong guarantee for the reliable operation of the ultra-high-voltage large power grid.

• [800MW/1600MWh！ Another energy storage project signed]
• On October 16, 2025, Jujinshi Energy Storage Technology (Chengdu) Co., Ltd. officially signed an investment agreement for the grid side shared energy storage power station project, and jointly launched a 1.6GWh energy storage demonstration project with the Jiamusi Natural Resources and Planning Bureau. It is reported that the project aims to solve the problems of regional new energy consumption and grid peak regulation, integrate resources through innovative shared energy storage models, and focus on building a provincial-level "new energy+energy storage" benchmark project to improve the efficiency of clean energy utilization. The total investment of the project is 2 billion yuan, and it is planned to layout four energy storage power stations in the suburbs, Dongfeng District, Huachuan County, and Fujin City, with a single station capacity of 200MW/400MWh. After the completion of the project, it is expected that the annual discharge income will reach 520 million yuan, and the annual tax payment will be about 60 million yuan, which will effectively drive local employment and regional economic development. At the same time, the operation of the power station will significantly enhance the regional new energy consumption capacity, strengthen the stability and regulation flexibility of the power grid, and provide strong support for the construction of a clean, low-carbon, safe and efficient modern energy system in our city.Editor/Bian Wenjun

• [Key projects such as graphene and lithium batteries have officially started construction]
• On October 17, 2025, the Huazhong Graphene Technology Industrial Park project officially started construction in Xiaogan City, Hubei Province. It is reported that the total investment of the industrial park project is 3.5 billion yuan, covering an area of 350 acres. It mainly produces products such as graphene heating flooring, large health therapy equipment, temperature sensors, lithium batteries, etc. At the same time, it carries out technological innovation and product research and development in cutting-edge fields such as graphene energy, optoelectronics, and materials. The project is scheduled to be put into operation in June next year. After reaching its production efficiency, it is expected to have an annual output value of over 1.8 billion yuan and an annual tax payment of over 75 million yuan. Graphene is known as the "king of new materials" and is the core force driving industrial upgrading. The Huazhong Graphene Technology Industrial Park will focus on the goals of "leading technology, green and low-carbon, and industrial synergy", creating a modern industrial base integrating research and development, production, and transformation, injecting new momentum into the optimization of industrial structure and high-quality economic development in Xiaonan District.Editor/Bian Wenjun
