Energize project to enhance electricity security for Quang Ninh province

At 10:40 p.m. on July 8, 2024, the National Power Transmission Project Management Board (NPTPMB) coordinated with relevant units to successfully energize the 220kV-250MVA Yen Hung transformer under the Capacity Enhancement Project of the Yen Hung the 220kV Substation. After completion, the substation capacity will be doubled.

The project is invested by EVNNPT, managed and operated by NPTPMB, and operated by Power Transmission Company No. 1. The project is implemented within the complex of existing Yen Hung 220kV Substation located in Minh Thanh ward, Quang Yen town, Quang Ninh province.

The project includes the scale of installing 01 220/110/22 kV-250MVA transformer; and equipment for 01 total 220kV feeder compartment of transformer AT2, on the 220kV side. The connection diagram is changed from a triangular diagram to a quadrilateral one. On the 110kV side, equipment for one 110kV total compartment of the 220/110/22kV transformer according to the diagram of two bus bars and ring bus bars and equipped with control, protection and measurement, communication, and SCADA systems in accordance with EVN and EVNNPT regulations, electrical equipment technical regulations and current regulations.

The project is completed with the goal of contributing to promoting production, attracting investment for economic development in Quang Ninh province and neighboring provinces, and ensuring sufficient capacity for industrial parks in the township of Quang Yen.

Since the beginning of the year, NPTPMB has energized 3 urgent projects, playing an important role in ensuring power supply in the 2024 dry season:

- Completing installation of shunt capacitors of 8 220kV substations;

- Installing 2 Thai Thuy 220kV substations;

- Installing 2 220kV Yen Hung substations.

Currently, the Board is accelerating the construction progress of the Project of the Thanh My 500kV substation expansion and renovation as scheduled to serve the purchase of electricity from the Monsoon Wind Power Plant (Laos) according to the bilateral agreement between the Governments of Vietnam and Laos.
