Energization of the connected third circuit of the 500kV power line 

At 8 pm on 31 July 2022, the National Power Transmission Corporation (EVNNPT)/Central Vietnam Power Projects Management Board (CPMB) in coordination with relevant units to energize technically the Vung Ang - Quang Trach 500kV power line. After energizing, the entire Vung Ang - Quang Trach - Doc Soi - Pleiku 2 third circuit, 500kV line project was connected.

Decisively operating to bring the project to the finish line 

The Vung Ang - Quang Trach 500kV power line project belongs to the project cluster of (Vung Ang - Quang Trach - Doc Soi - Pleiku 2) third circuit, 500kV power line projects is invested by EVNNPT.

Although the route from Vung Ang 500kV substation (Ha Tinh) to Quang Trach (Quang Binh) 500kV Distribution Switchyard is just over 32km long, it encounters many problems in site clearance.

To ensure the completion of the project in July 2022 under the direction of Vietnam Electricity, EVNNPT has directed and requested CPMB and project participants to mobilize all resources to accelerate construction progress, at the same time, coordinate and work closely with the Town Party Committee, People's Committee of Ky Anh town, Ha Tinh province to solve obstacles in compensation for site clearance to meet the required progress. 

Every day, EVNNPT's leaders hold an online dispatching meeting at the early hour, and at the same time send a delegation of specialized departments of EVNNPT to closely follow the field to direct the construction. EVNNPT together with construction units coordinates human resources with the motto of concentrating maximum resources for the project.

In the work of technology acceptance and acceptance of the route corridor, EVNNPT has agreed with the supervision consultancy, design consultancy, and operation management units with the motto "Construction to where acceptance is completed there”.

The section of the Vung Ang - Quang Trach 500kV power line has been completed and energized 

Improving North-South power transmission capacity

According to EVNNPT Deputy General Director Truong Huu Thanh, the energization of the Vung Ang - Quang Trach 500kV power line project has an important meaning in completing the entire third circuit of the 500kV power line project. When the project is completed, it will contribute to improving the 500kV power line transmission capacity of the national power system; release the capacity of thermal power and renewable energy sources in the region; contribute to ensuring electricity supply for Ha Tinh, Quang Binh, Quang Tri, Thua Thien Hue, Quang Nam, Quang Ngai, Gia Lai, Kon Tum, Da Nang city, and surrounding provinces.
