Recently, the 500kV Xuwen East Power Transmission and Transformation Project, surveyed and designed by GEDI, was put into operation.

The project includes the construction of a new 500kV Fengxiang Substation and a direct 500 kV line of approximately 60 kilometers to the Wushiwan Power Plant, as well as the expansion of one GIS bay on the power plant side. Upon commissioning of the project, offshore wind power in the Xuwen area of Zhanjiang will be gathered and transmitted, bundled with traditional thermal power, to the load center of the Guangdong-Hong Kong-Macao Greater Bay Area. This will address the short-term and long-term strategic demand for the transmission of over 1500 MW of new energy from western Guangdong.

For this project, the GEDI design team innovatively propose a system solution of "wind-thermal bundling and channel sharing" to tackle the challenges of large-scale grid connection and transmission of offshore wind power in the Zhanjiang sea area. This approach leverages conventional power sources to mitigate the fluctuations of new energy, ensuring stable grid operation, while also conserving valuable corridor resources. Furthermore, utilizing BIM technology, the team establish a full-life-cycle digital model, achieving digital integration across the entire process of design, production, construction and O&M. The team also independently develop advanced technologies such as the hinged node for resting steel corbels, visual high-performance grouting sleeves, and a multi-layer protective sealing system for exterior walls. The first prefabricated main control building that implements full support-free technology for precast concrete components is built, providing a highly reliable pathway for carrying out construction in the demanding coastal environment.
