en.Wedoany.com Reported - Recently, the first key 750 kV grid hub project of Ningxia's "15th Five-Year Plan"—the Fengsui 750 kV Power Transmission and Transformation Project—was officially completed and put into operation. Located in Huinong District and Pingluo County of Shizuishan City, Ningxia, the project was designed with participation from the Northwest Electric Power Design Institute of China Energy Engineering Group. It includes the new construction of the Fengsui 750 kV substation, the expansion of the Shahui 750 kV substation bay, and supporting transmission line works. The Northwest Electric Power Design Institute is responsible for the design of two 750 kV transmission line projects: the Pingluo Power Plant-Shahui Loop I tapping into Fengsui and the Fengsui-Shahui line, with a total line length of approximately 113 kilometers and 165 newly built towers.
After the project's commissioning, a stable 750 kV three-dimensional double-ring network structure can be formed. In the near term, it can support a power load of 3,000 MW, and in the long term, the load capacity can be increased to 6,000 MW. The completion of the project fills the gap in the northern Ningxia 750 kV main grid framework, upgrading Shizuishan from a grid power supply endpoint to a regional power hub, thereby enhancing grid power supply reliability and resource allocation capabilities. According to State Grid Ningxia Electric Power, the construction faced complex conditions such as soft geological foundations in the Yellow River floodplain and high groundwater levels. The construction team innovatively adopted BIM technology for pre-planning and integrated construction techniques, building Ningxia's first 750 kV HGIS trackless dust-proof workshop.
The construction of the Fengsui 750 kV Power Transmission and Transformation Project has smoothed the channel for integrating and transmitting new energy from the northern region, facilitating the large-scale consumption of clean energy from wind and solar power. It plays a positive role in optimizing Ningxia's grid layout and promoting the transformation of the energy structure.
