[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.

Recently, the main project of Hubei Songzi Pumped Storage Power Station, which China Energy Engineering Gezhouba Group participated in, started construction. The power station is located in Songzi City, Jingzhou, with a total installed capacity of 1200 megawatts, and belongs to the first-class large (1) type project. Gezhouba Group undertakes the construction of the upper reservoir and the installation of metal structures, with a contract amount of 712 million yuan and a construction period of 48.5 months. After the completion of the power station, it will undertake tasks such as peak shaving, valley filling, energy storage, and frequency regulation, which is of great significance for ensuring the safety of the power grid and supporting the consumption of new energy.Editor/Cheng Liting
On June 1, 2026, the Guangzhou Eastern Center Intelligent Fusion New Energy Storage Industry Demonstration Project invested and constructed by Zengtou Energy Company, a subsidiary of Zengcheng Urban Investment Group, officially started construction. The total investment of the project is nearly 467 million yuan, and a new 150MW/300MWh electrochemical independent energy storage power station will be built. It will adopt lithium iron phosphate battery technology and be connected to the power grid at 110kV, with the functions of peak shaving, frequency regulation, and promoting the consumption of new energy. The project is supported by a comprehensive operation and maintenance building, an electrical building, and auxiliary facilities such as fire protection, and is promoted through an integrated construction and operation model.Editor/Cheng Liting
