At 20:42 on 13 September 2021, the Project Management Board of Central Power Works (a member of National Power Transmission Corporation) in coordination with related units energized the AT1 transformer project (220kV-250MVA) of  Lao Bao 220kVsubstation, thereby completing the entire project of substations serving to release the capacity of wind power plants in the west of Quang Tri province to the power system.

Previously, on 30 June 2021, the AT2 transformer (220kV-250MVA) was energized. Thus, Lao Bao 220kV substation is ready to release capacity for wind power plants in the west of Quang Tri province to be ready for commercial operation.

The work belongs to the project of  Lao Bao 220kV substation and  Dong Ha - Lao Bao 220kV power line, is invested by the National Power Transmission Corporation (EVNNPT), and ), is managed and operated by the Projects Management Board of Central Power Works (CPMB), is undertook the operation by Power Transmission Company 2.

AT1 transformer at Lao Bao 220kV substation has just been successfully energized

Lao Bao 220kV substation (Tan Hop commune, Huong Hoa district, Quang Tri province) has a new scale of building one 220/110/22kV substation including two 250MVA transformers.

The work was completed on schedule despite the complicated disease situation, showing the great efforts of CPMB and construction units on the construction site. 

At the same time, the Dong Ha - Lao Bao 220kV power line is also expected to be energized by the end of September 2021. These are important works in ensuring wind power plants into commercial operation before 1 November 2021 (the milestone according to Decision 39/2018/QD-TTg of the Prime Minister), for wind power plants to operate efficiently and maximize capacity.

Along with that, the project contributes to transmit the capacity of hydropower plants in the west of Quang Tri province to the national power system; contributes to ensuring power supply for Quang Tri province.
