Nam Tay (Tai) Dam Hydropower Info by Hobo Maps - Go to Hydropower Projects Page - - Home
The Nam Tay (also spelled as Nam Tai) is a small tributary river of the Nam Ngiep (river) in northern Lao PDR. The Nam Ngiep flows southeast and eventually merges with the Mekong River near Paksan, Laos.
The Nam Tay (Tai) Hydropower project site is in Thathom District of Xaysomboun Province. There are two sites about 6 km north of Dong Mo village which is not far off of Highway 1D about 2 km east of Thathom town.
Very little info known about this project and in 2024 still unsure of where the water source is and if there may be a reservoir further north of the powerhouse. Newer satellite images are needed.
The satellite images below show Nam Tai (Tay) Hydropower project locations.
The Nam Tay (Tai) Hydropower project is originally developed by Lao-based Phongsubthavy Group (also spelled Phongsupthavy) with intent for export of the electric output to Vietnam.
Phongsubthavy Group is active in other hydropower projects in northern Laos and in 2020 and 2021 entered into various Memorandums of Understandings (MOUs) with Electricity of Vietnam (EVN) for offtake of the output as purchaser.

In late December 2021 it was announced that Thai-based BCPG Indochina Co. (BIC) has purchased 25% of the ordinary shares of Nam Tai Power Sole Company Limited in the approximate amount of USD 32 million. It seems that Nam Tai Power Sole Company Limited is the owner of the Nam Tay (Tai) Hydropower project but we aren't sure. This same purchase also involved an ownership interest in the new 220 kV transmission line.
In any event it seems that BCPG Indochina Co. is now a part owner of the new transmission line and has the right to transmit electric energy output from its Lao hydropower plants to Vietnam for sale to EVN. BCPG Indochina Co. also owns two other hydropower projects in the same area as Nam (Tay) Tai Hydropower - Nam San 3A & Nam San 3B.

The Nam Tay (Tai) Hydropower plant will have three turbine generator sets of 9 MW each for total capacity of 27 MW and estimated annual output capacity of 101 GWh. Another source indicates the project will only have 21 MW capacity.
The project in 2024 is probably completed or close to completion.

Nam Tay (Tai) hydropower project is one of 11 hydropower plants being developed by Phongsubthavy Group to sell electricity to Vietnam through a 79 km 220kV transmission line Nam Mo - Tuong Duong (Nghe An) invested by Phongsubthavy Group for the section in Laos and Electricity of Viet Nam (EVN) for the section in Vietnam. The transmission line was originally scheduled for completion in 2022. See images below.
