At 23 hours 08 minutes, on February 3, 2024, the Central Vietnam Power Project Management Board (CPMB) coordinated with related units to energize the 220kV Nha Trang-Thap Cham double-circuit transmission line, in practical celebration of the 94th anniversary of the establishment of the Communist Party of Vietnam (February 3, 1930 – February 3, 2024).
The Nha Trang-Thap Cham 220kV transmission line project (circuit 1) and the hanging line project of circuit 2 of the Nha Trang-Thap Cham 220kV transmission line (circuit 2) are invested by the National Power Transmission Corporation (EVNNPT). CPMB manages the project, and Power Transmission Company 3 takes over the operation.
The project has a construction scale of a 220kV transmission line with 2 circuits, over 88 km long; constructing 2 new 220kV outgoing circuits (1 circuit each) at Nha Trang 220kV Substation (Khanh Hoa province) and 2 outgoing circuits of 220kV (1 circuit each), one circuit for cutting ring and grounding at Thap Cham 220kV Substation (Ninh Thuan province).
The goal of the project is to create a 220kV network connecting the coastal area of Central Vietnam, enhance the reliability of power supply to the area; ensure safe operation, improve the reliability of power supply to Khanh Hoa-Ninh Thuan provinces, meet the release of capacity from solar power plants and wind power plants connected to the 110kV, 220kV grid in Ninh Thuan, Binh Thuan provinces in the coming period.
During the construction process, the project encountered numerous difficulties and obstacles in land clearance compensations, the construction conditions faced many challenges when many pole positions were located on mountain tops, treacherous terrain, the weather in the area was always windy causing difficulties in foundation casting, pole erection, and wire pulling.
In addition, the transmission line intersects with many power release lines in the area, so the registration for power cuts takes a lot of time, so CPMB had to organize power shutdowns in different stages (previously there were power shutdowns for phase 1 and phase 2 of the project).
However, with the close guidance of the leadership of the National Power Transmission Corporation, the support of local authorities and residents where the project passes through, and the efforts of CPMB and the units participating in the project, the project completed both circuits of the transmission line, meeting the set progress targets./.
