Consultants sought for study of Laos’ 460-MW Nam Ngum 3

The Asian Development Bank (ADB) seeks expressions of interest from consultants to carry out a cumulative impact assessment for the 460-MW Nam Ngum 3 hydroelectric project, proposed for Laos’ Nam Ngum River Basin. Responses are due November 30 and December 8.

ADB approved US$983,000 in technical assistance to Laos’ Ministry of Energy and Mines for a cumulative impact assessment study consistent with the government’s environmental and social sustainability policy for the hydropower sector, as well as ADB policy. (HNN 9/27/06)

The study would assess effects of the project, predict major cumulative environmental impacts of Nam Ngum 3 and other developments in the basin, indicate threshold levels of sustainable development, and set environmental parameters and targets. The results are to be used to develop a comprehensive environmental and social mitigation plan.

Thailand’s biggest private power producer, Ratchaburi Electricity Generating Holding PCL, said in January that it would buy a 25 percent stake in Nam Ngum3. Ratchaburi said it, another Thai company, a Japanese firm, and the Laos government plan to bring the project on line in 2013.

ADB said a team of international consultants is required to carry out two components of the technical assistance program. Component A will require consultants with expertise in water resource management, environment, hydrology, water quality, aquatic and terrestrial ecology, land use, social impact, health, geographical information systems, planning, and design and implementation of a monitoring program. Component B will require consultants with expertise in environment management and capacity building.

Expressions of interest (EOI) may be submitted via the ADB Internet site,, under Opportunities/Business Opportunities/Consulting Services Recruitment Notices/Lao Peoples Dem Rep. Component A (Package 1) EOIs are due December 8, while Component B (Package 2) EOIs are due November 30. Terms of reference are on the website.

Laos’ Ministry of Energy and Mines is the executing agency for the program. The ADB project officer is Edvard M. Baardsen, Senior Infrastructure Specialist, Asian Development Bank, Lao Resident Mission, Manila, Philippines; (63) 2-6325544; E-mail:; Internet:
