Nam Che 1 Dam Hydropower Info - Namche 1 Dam - by Hobo Maps- Go to Hydropower Projects Page - - - HOME
Nam Che 1 Hydropower project is located near Namlong village and Samgorthong village, Thathom district, Xaisomboun Province in Lao PDR.
The project has a small dam and reservoir. The powerhouse contains two 8.4 MW Francis turbine-generator units for 16.8 MW total installed capacity. Annual output is estimated at 68.4 GWh.
The project developer, Nam Che 1 Hydropower Company Limited is a joint venture between Thai-based B. Grimm Power Co. Ltd. (a unit of B. Grimm Group) and Daosavanh Co. Ltd. (an engineering company based in Laos).
Nam Che is pronounced like "Nam Chay".

The Nam Che 1 Hydropower plant project has been supplying electricity to Electricte du Laos (EDL) for domestic consumption since June 1, 2019 (Commercial Operating Date) under a 25-year power purchase agreement.
The run-of-river hydro project is on the Nam Che River in Xaisomboun province and was estimated to cost US$ 49 million.
Austria-based GLOBAL Hydro Energy was a major contractor for the project by providing a comprehensive turnkey package of electromechanical and control infrastructure.
Nam Che 1 Dam images below - we can see the Nam Chiane 1 penstock and power plant in the upper background not far away and north of the Nam Che 1 dam and reservoir seen in the lower area of these images:



The dam structure is 23 meters high and 50 meters across with an overflow edge and two weir gates.
Sediment in the water is settled-out in a stilling chamber ahead of the high-pressure channel when flow velocity is reduced, possibly negating the need to install a desander.
Most of the 300-meter head water-descent stage is encased in an underground concrete conduit. The water then flows into an above-ground steel channel just before the power plant.
The power generated is conducted from the generator to medium-voltage switchgear, then to transformers and finally to Thavieng Substation via a 15 km-long transmission line.
