Electricity Generating Authority of Thailand (EGAT) has opened Udon Thani 3 substation that receives electric power from Nam Ngum 2 dam in Laos. It is the coordination between 2 countries to develop energy in the region.

     The opening ceremony of the Udon Thani 3 substation was co-hosted by Mr. Seni Jittakasem, the Governor of Udon Thani province and Mr. Sutat Patmasiriwat, the EGAT Governor on November 20, 2012 in Mueang district, Udon Thani province. In the ceremony, Mr. Wasan Saengsuwan, the director of Northeastern Region Operation Division reported the purpose of the opening ceremony, while Mr. Thana Putarungsi, the Deputy Governor - Transmission System and many EGAT staff joined the event.

     EGAT governor said that since the government of Laos signed the agreement to sell electricity to Thailand with the total capacity of 7,000 MW by 2015, EGAT constructed Udon Thani 2 substation in the area of 185 rais at Nong Na Kham sub-district, Mueang district, Udon Thani province to import electricity from Nam Ngum 2 dam in Laos by receiving the electrical power from Na Bong substation. The construction was completed, and it started its initial operation on December 25, 2011. 

     EGAT has also developed its transmission system to support the power import from Laos by installing transmission lines crossing Mekong River with the voltage of 500 kV at the border of Nong Khai to interconnect Udon Thani 3 substation and Nam Phong 2 substation with the total length of 85 kilometers. The lines also interconnect the transmission lines with the voltage of 115 kV around Nong Khai, Udon Thani and Sakon Nakhon to boost the capacity of transmission system.

     This is the success of the power coordination between Thailand and Laos. The agreement between two countries has brought benefits to both. While Laos has earned money, Thailand can cut cost of investment and strengthen the electricity system security. Moreover, it enhances the relationship between two countries.
