The energization of 500kV-450MVA AT2 transformer at 500 kV Pleiku 2 substation is to receive capacity from hydropower plants such as Xekaman 1, Xekaman Xan-say, upper Sekong 3, lower Sekong 3 in Laos toward Vietnam through the 220 kV Xekaman 1 - Pleiku 2 transmission line in order to supply power to the Central and Western Highland areas and the Southern provinces; the power grid interconnection will contribute to a sustainable development of energy in the international integration, regional cooperation and connection conditions; reduce power loss and create conditions for an optimal exploitation and operation of power system of Vietnam.

The project "Installing 500/220kV transformer at 500 kV Pleiku 2 substation and 220kV connection" has a total cost of nearly VND 584 billion invested by EVNNPT, Central Power Projects Management Board (CPMB) manages the project, Power Engineering Consultation Company No. 4 (PECC4) is responsible for project design, Power Construction Company No. 1 (PCC1) is responsible for project implementation, the Central Power Testing Company is responsible for project testing, Power Transmission Company No. 3 (PTC3) takes over the project management and operation.

Scope of the project: installing 02 500/220/35kV-450MVA transformers and distribution equipment at 500 kV Pleiku 2 substation; installing the protection control system; Constructing a section of a double circuit 220 kV transmission line from the 500 kV Pleiku 2 substation connected directly to the existing single circuit 220 kV Pleiku – Krong Buk transmission line, of a length of about 3.8 km.

The project is constructed in the 500 kV Pleiku 2 substation in O So villagem Ia Kenh commune, Pleiku city, Gia Lai province.

This is one of 3 projects in Pleiku 2 project block, including 500 kV Pleiku 2 substation; The 220 kV Xekaman 1 - Pleiku 2 transmission line; Installing the 500/220kV transformer in 500 kV Pleiku 2 substation and 220kV connection.

Before that, on April 15th 2016, EVNNPT completed the 500 kV Pleiku 2 substation project and on April 12th 2016, the 220 kV Xekaman 1 - Pleiku 2 transmission line project was energized.
