Gamuda will be building the 177m height Nam Theun 1 dam, located on the lower reaches of the Nam Kading in central Laos, as part of a BOT project supplying hydroelectric power to Thailand. The dam is of an RCC design, requiring 3 million cubic meters of concrete placement.

Gamuda is the lead shareholder in the 450MW Nam Theun 1 hydropower project located in central Laos, which would supply 2,000 GWh of hydroelectric power to the Electricity Generating Authority of Thailand. The project is under the auspices of an inter-government agreement for Thailand to purchase 3,300 MW of power from Laos bringing much needed development to Laos while providing Thailand and Laos with clean, renewable electric power.
