On March 27, power transmission officially commenced for the 500 kV Yungu Power Transmission and Transformation Project, surveyed and designed by GEDI.

The project involves the construction of the new 500 kV Yungu Substation, along with four 500 kV and seven 220 kV outgoing lines. By transmitting approximately 7 billion kWh of clean electricity annually, it will inject strong momentum into Guian New Area's development as a national hub node for the integrated computing power network and a nationwide computing power guarantee base.

Situated in a karst region, the project faced complex geological conditions and significant construction challenges. Adhering to green and low-carbon principles, the GEDI project team innovatively proposed an integrated mobile crushing station and a crushed-stone soil fill foundation treatment solution. This approach reduced the need for off-site stone disposal and purchased earthwork by approximately 60,000 cubic meters while significantly enhancing foundation bearing capacity and stability. Furthermore, through the extensive application of green industrial building technologies and the use of highly efficient, energy-saving equipment, the overall project achieved a three-star rating in the green and low-carbon power grid evaluation. Additionally, an intelligent auxiliary integrated monitoring system is deployed at the substation.
