• Theun Hinboun Expansion Project is the extension scheme of the existing Theun Hinboun. The extension scheme consists of the development of a storage dam at the Nam Gnouang with 60 MW installed capacity to supply the domestic demand by connecting with the EDL substation at Tha Sala. The regulating flow from Nam Gnouang can enhance the power production at the existing Theun Hinboun by installing 220 MW more as an extension resulting in the total installed capacity of 440 MW. The commercial operation of the extension project started in 2012.
