The transmission line connections include: A 220kV double-circuit transmission line (with one circuit strung) from the Nam Emoun Hydropower Plant to the 220kV Dak Ooc switching substation (the section on Vietnamese territory), about 13.4km length; construction of a 4-circuit 220kV transmission line, with a length of about 1.9km from the 220kV Dak Ooc switching substation to the transition point into the existing 220kV Xekaman 3 - Thanh My double-circuit transmission line; construction of a 22kV power supply line for construction and self-consumption from the local grid to the 220kV Dak Ooc switching substation, about 1.077km length.

Starting construction on July 25^th, 2022, overcoming many difficulties during the construction process, the 220kV Dak Ooc switching substation project has been successfully energized. It is expected that the transmission line connections will be completed and energized in August 2024.
