Nam Ngao Dam Hydropower info by Hobo Maps - Go to Hydropower Projects Page - - - HOME

Nam Ngao Hydropower Project is located near Ban Namsen and Pak Ngao, Houy Xay District, Bokeo Province, Lao PDR about 15 km northwest of Houay Xay, the capital of Bokeo Province.

The project is developed by Laos-based Heuangpaseuth Hydropower Co., Ltd..

The installed capacity is 15 MW (2 at 7.5 MW) with annual 58 GWh power capacity.

The approximate coordinates of the project site are: 20°23'00.6"N 100°23'39.1"E (20.383500, 100.394200)

Nam Ngao Dam location is shown in image below:

The project is a run-of-river hydropower type which includes fixed weir with head pond, sandtrap, intake structure, headrace canal, headrace tunnel, forebay, penstock, powerhouse and tailrace.

The developers claim the construction of the project will not result in displacement of residents or inundation of houses.

The project is expected to contribute clean green energy to the Lao and Thai Power grids and to qualify as a Clean Development Mechanism (CDM) project under the Kyoto Protocol and earn carbon-reduction credits. By displacing part of the power generated by polluting power plants, the project is expected to reduce CO2 emissions by an estimated 45,375 tons per year during the first crediting period.

There is conflicting information on the web about the project's number of turbines and rated capacity of output. We aren't sure which version is correct, either 15 MW or 18 MW.
