Nam Kap is sometimes also spelled Nam Karp or Namkarp.

The 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 direct line).

Nam Kap hydropower project location is shown below at general coordinates - 19°01'07.7"N 102°44'39.1"E (19.018806, 102.744194)

The project is a run-of-the-river hydropower type without a large reservoir.

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 went back under construction around 2019 and in 2024 looks to be complete and operating.

Lao-based Phongsupthavy Group became the developer of the project after the delays. We aren't sure who the project owner may be as there were changes to get things back on track.

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

Tonam Energy apparently did civil work for the powerhouse and penstock, gate works, machinery and equipment installation and 115 kV switchyard.

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

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