Reporting at the working group, Mr. Vu Van Loc, Director of Power Transmission Ninh Binh said, the unit was assigned by Power Transmission Company 1 (PTC1) to manage and operate the regional power transmission grid at voltage level 220-500kV in the provinces of Ninh Binh, Nam Dinh, Thai Binh, Ha Nam and part of Hoa Binh province are responsible for main power supply to Hanoi and the southern provinces of the Red River Delta.
To ensure the operation of the Central-Northern power grid to supply power to the North in the 2024 dry season, Ninh Binh Power Center has seriously implemented instructions from all levels on ensuring safe operation and preventing incidents; Making plans to prevent incidents for each power transmission team and Substation and implement them. The unit has regularly inspected technical management, discipline, and requirements in the operation of Substations to point out defects and shortcomings and require Substations to implement remediation to ensure safe operation of the power grid.
At critical locations, the unit has installed additional shields to enhance current guidance and prevent heat generation. In addition, periodically carry out testing in full volumes and items according to regulations.

For Thanh Hoa Power Transmission, the unit has seriously carried out technical management inspections at Substations once a quarter; and applied software to improve efficiency such as relay calibration, testing management, equipment management, etc. Seriously and effectively implement solutions to prevent incidents according to the content of the plan approved by PTC1 such as preventing heat generation, insects, moisture protection, insulation, CSV leakage current measurement, secondary completion review, and so on.
As of February 20, 2024, Thanh Hoa Power Center has implemented 224/506 lists of periodic testing equipment, reaching 44.26%, at the same time, continue to strive to complete the volume of periodic testings before March 30, 2024. At the Substations, the unit has replaced old, long-standing equipment to ensure grid synchronization; reviewed configuration and adjustment of relays to ensure accurate and selective operation; cleaned hotline insulation, strengthening contact points, and water cooling system to increase the load capacity of transformers; deployed the application of science and technology at Substations and power transmission teams, including applying UAVs in line operation management, and so on.
At the meeting, representatives of the Electricity Regulatory Authority, EVN's professional departments, and EVNNPT leaders discussed and recommended solutions to improve power transmission capacity, ensuring operation of the Central - North 500kV circuit at lines and substations managed by Ninh Binh Power Center and Thanh Hoa Power Center.

Power Transmission Company 1 and two power stations need to strengthen operational management, absolutely not allowing subjective incidents to occur. It is required to strengthen monitoring of the operating situation, especially the Central - North 500kV backbone line, minimize incidents occurring during high transmission periods and review and fully prepare incident handling plans; strengthen the force on duty to operate/troubleshoot high load lines and elements in the dry season of 2024.
Member of EVN’s Board of Members Dang Huy Cuong, Vice President of EVN Ngo Son Hai, and the working group inspecting the Relay room at the Nho Quan 500kV Substation.
The transmission network is managed by PTC1 with many main tasks, including high transmission on the 500kV circuit, connecting from the Central region to the North and vice versa; ensuring power supply for Hanoi Capital and important load areas in the North; releasing hydroelectric sources in the Northwest region; meet the demand for electricity import to Vietnam. Therefore, careful and thoughtful preparation and implementation for the operation of 500kV circuit lines and substations linking Central–North will contribute to helping Vietnam Electricity strive to carry out the task of ensuring power supply in the dry season of 2024 in particular and in 2024 in general.
