Nam Kap is sometimes also spelled Nam Karp.

Nam Kap Hydropower Project is located near Ban Naty, Long Chieng district of Xaysomboun province, Lao PDR about 35 km northeast of Vang Vieng town (by straight line).

Nam Kap hydropower project location is shown below at coordinates - 19°01'36.8"N 102°44'29.7"E (19.026889, 102.741595).

The project is a run-of-the-river hydropower type.

Installed capacity is 12 MW (2 x 6 MW) with up to 54 GWh power output annually.

The project started a few years ago but there was a delay in construction. The project is back under construction and in 2024 looks to be close to completion.

Due to these delays we aren't sure who the project owner and developer currently are since it seems there were changes to get things back on track. Phongsubthavy Group filed a CDM document in July 2019 on behalf of the project and is most likely the developer.

FM Construction Sole Co. Ltd. was involved with the restart of construction.

The project includes fixed weir, sandtrap, intake, headrace canal, headrace tunnel, forebay, penstock, powerhouse, switchyard and a tailrace.

The penstock diameter goes from 1.7 meters to 1.3 meters closer to the powerhouse.

The power generated will be delivered to Electricite Du Laos (EDL) through a 115 kV single-circuit transmission line.

Nam Kap HPP satellite images below also show a nearby mysterious project about 2 km above Nam Kap main facilities that may or may not be part of the Nam Kap project. Please help clear this up if you can by email to us at Hobo Maps.
