In March 2015, Simeuang Group Company Limited (Simeuang Sole Power Company Limited), project owner of the Nam Houng 1 hydropower plant, signed a construction agreement with three Korean contractors to build the plant. The three are Dowoo Engineering JV, Phunglin Industry Co. and Dowoo Construction and Engineering Co.. The contract covered the full scope of the civil works at the hydropower plant at a cost of US $16.9 million.
Maybank Lao Branch, Joint Development Bank (JDB) and Lao-based Simuong Group (SMG) each signed agreements in 2015 to provide construction funds to Nam Houng Hydropower Company Limited in Vientiane.
The plant will have 15 MW installed capacity and be able to produce 57 GWh output per year. The project expects to sell all power generated to Electricite du Laos (EDL) for supply to the national grid.
Construction on the U.S. $34 million, 15-megawatt Nam Houng 1 Dam project began in 2017 but was delayed for a year due to the discovery of substandard work on the project. Construction resumed in 2018 and in July 2023 it was reported that construction was 100% complete and undergoing testing of systems for full start of commercial production soon.
