Both the seller (NTPC) and the main buyer (EGAT) have built transmission lines on their own sides of the Lao-Thai border for delivery at the border. Accordingly, electricity generated at the power station for EGAT is delivered to the border near Savannakhet via a 138-km double-circuit 500 kV transmission line constructed by the Project. EGAT has constructed a 160-km 500 kV line from the border to its substation at Roi Et in north-east Thailand. The electricity delivered at the power station for EDL is transmitted to Thakhek via a 70-km long 115 kV transmission line. EDL will also take up to 15 MW of energy from the power station switchyard via 22 kV lines to the resettlement villages.
