[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.

• In July 2026, the Guxian Water Conservancy Hub Project on the Yellow River entered a comprehensive acceleration stage. As a strategic project for Yellow River management, its dam site controls over 60% of the basin area. After the official start of construction in 2024, a large amount of earthwork and concrete work has been completed. In 2027, the river will be intercepted, and after full completion in 2034, it can supply water to more than ten million acres of farmland in Shanxi and Shaanxi, and supplement the follow-up power of Xiaolangdi water and sediment regulation.

• Since the beginning of summer, the Yangtze River has entered a period of abundant water, greatly improving its shipping capacity. As the only LNG refueling hub in the Three Gorges Reservoir area that operates stably year-round, the LNG refueling terminal in Guizhou Town, Zigui County, Hubei Province is known as the "green energy supply station" on the water in the Three Gorges Reservoir area. Since its official operation, the refueling volume has continued to steadily increase. In June 2026, the monthly refueling volume of the terminal exceeded 1000 tons for the first time, setting a new monthly record since its commissioning. Editor/Cheng Liting
