Nam Peun 1 (Nam Pern 1) Dam Hydropower Info by Hobo Maps - Go to Hydropower Projects Page - - Home

Nam Peun 1 hydropower site is located on the Nam Peun (river) in Houameuang District of Houaphan Province about 3 km north of Ban Sop Peun village (where the Nam Peun joins the Nam Neun river).

The Nam Peun 2 hydropower project (finished in 2017) is located on the upper area of the Nam Peun river with the Nam Peun 1 project (finished in 2018) located in the lower area.

The Nam Peun 1 power house satellite image below shows the Nam Peun (river) with almost no flow in the river channel above the blue-roof powerhouse building and a nice flow out from the building which makes it seem that water for the turbines enters the powerhouse from an underground conduit of some sort. This intake may be on the Nam Peun further upstream of the power house.

Nam Peun 1 hydropower project powerhouse is the blue-roof building on satellite image below:

The Nam Peun (river) is a tributary of the Nam Neun (river) in northern Lao PDR. Click to see our - Satellite view map of Nam Peun river.

On satellite images of the Nam Peun (river) we can see an upriver dam and head pond that may be an intake source for an underground tunnel taking water down to the blue-roof powerhouse building.

Nam Peun 1 head pond in upper right of image below is at coordinates - 20°00'26.4"N 103°56'30.7"E (20.007333, 103.941861)

Nam Peun 1 hydropower project was developed by Nam Peun 1 Power Company Ltd. and by Phongsubthavy Group.

The Nam Peun 1 facility has 3 horizontal Francis turbines rated at 9.7 MW each for total generating capacity of 29.1 MW.

The power plant was finished and commissioned in 2018.

The project has a head of 114 meters. The final road to the project has steep grades of up to 18% incline making access to the remote site difficult.

The Nam Peun river ends as it joins the Nam Neun about 26 km southeast of Ban Sop Lao as shown below:

A Vientiane Times news report in June 2024 indicates the Nam Neun 1 hydropower project plans to start exporting its power output to Vietnam in 2028. Since the Nam Peun 1 & 2 hydropower projects are very close to the Nam Neun 1 HPP and also close to the transmission lines for the Nam Yeuang Cascade group (that export power to Nong Cong Vietnam) we are guessing the Nam Peun output may soon connect to the Nam Neun and Nam Yeuang project transmission line as shown in the map below with output exported to Vietnam.
