The Nam Theun 2 Hydroelectric Project is owned by a consortium of private shareholders and the Lao Government. It entered commercial operation in 2010. The hydroelectric potential of the project is created by an elevation difference of 350 m between the Nam Theun on the Nakay Plateau and the receiving Xe Bang Fai on the Gnommalath Plain. Both rivers are tributaries of the Mekong. The project comprises a 450 km2 reservoir, a short tunnel system, a surface powerhouse, a regulating pond and a 27 km long downstream channel to the Xe Bang Fai. The powerhouse is equipped with 4 x 250 MW Francis units and 2 x 35 MW Pelton units. Power export is via a 500 kV transmission line to the border with Thailand.
