Lightning-fast construction, Lao Cai - Vinh Yen 500 kV transmission line completed 8 months ahead of schedule

Today, EVN Group inaugurated the 500 kV Lao Cai - Vinh Yen transmission line, a particularly important project that serves as a strategic energy link between the Northwest region and the rest of the country.

Attending the inauguration ceremony, Deputy Prime Minister Ho Duc Phoc emphasized: This project is of đặc biệt importance in ensuring national energy security, providing a solid foundation to promote growth of over 8% in 2025 and double-digit growth in the coming years.

Providing an additional 3,000 MW of electricity.

The Deputy Prime Minister emphasized that Vietnam's socio -economic growth targets for this period require the electricity sector to focus on development, increasing power generation capacity annually by approximately 15-18% (equivalent to 8,000-10,000 MW) to ensure electricity supply for economic development and attract domestic and foreign investment.

Given this reality, the Lao Cai - Vinh Yen 500 kV transmission line project is of particular importance, promptly increasing the power transmission capacity from hydropower plants in the Northwest region and neighboring provinces to the national grid by approximately 3,000 MW. At the same time, it will meet future electricity supply cooperation needs with China; ensuring proactive and flexible management, balancing electricity supply, and guaranteeing national energy security.

Deputy Prime Minister Ho Duc Phoc attended the inauguration ceremony of the Lao Cai - Vinh Yen 500 kV power line project.

The 500 kV Lao Cai - Vinh Yen double-circuit transmission line has a total length of 229.5 km and a total of 468 tower foundation locations. The project passes through two provinces, Lao Cai and Phu Tho (formerly four provinces: Lao Cai, Yen Bai, Phu Tho, and Vinh Phuc), with the starting point at the 500 kV Lao Cai substation and the end point at the 500 kV Vinh Yen substation. The total investment for the project is over 7,410 billion VND.

To ensure synchronized and efficient operation, the second phase of the Lao Cai 500kV Substation project, with a total investment of over 1,564 billion VND, has also been completed, including the construction and energization of the 500kV switchyard and 500kV transformers, in order to synchronize with the Lao Cai - Vinh Yen 500kV transmission line project.

After commissioning, the 500kV Lao Cai - Vinh Yen transmission line will be capable of transmitting approximately 3,000 MW from hydropower plants in the Northwest region and neighboring provinces to the national grid, increasing the capacity for electricity imports. Simultaneously, it will create a strong link between regions within the power system; improve the safe and stable operation of the national power system; reduce power losses in the transmission grid; and increase the efficiency of electricity production and business for EVN.

Deputy Prime Minister Ho Duc Phoc delivered a speech at the inauguration ceremony.

Six months of rapid construction.

According to EVN, with the highest level of determination and effort, implementing the "4 on-site" construction method, "3 shifts, 4 teams," "overcoming sun and rain," and "working through holidays and weekends," after more than 6 months of construction, the project has completed the main construction volume including: Excavating nearly 1.8 million m3 of soil and rock for foundation pits; Pouring nearly 110,000 m3 of concrete with approximately 7,500 tons of reinforcement steel; Producing and erecting 55,000 tons of steel poles; and laying more than 6,000 km of various types of cables (26 conductors, lightning protection wires, and fiber optic cables).

This schedule has shortened the timeline by nearly 8 months compared to the approved schedule.

EVN's technical staff operate the system at the Dispatch Center in Xuan Quang commune, Lao Cai province.

Mr. Nguyen Anh Tuan, General Director of EVN Group, affirmed that the Lao Cai - Vinh Yen 500 kV power line is a project celebrating the successful conclusion of the first Party Congress of the Government for the 2025-2030 term, and looking forward to the 14th National Congress of the Party.

According to Mr. Tuan, during the construction process, the project faced many difficulties and challenges, ranging from harsh weather conditions, rugged mountainous terrain, complex geology, large-scale land clearance, to the urgent deadline.
