11 “Nam Theun 2 Hydropower Project: additional dams are built in the same river basin. The Nam Theun-Hinboun dam, located approximately 40 km downstream of the proposed site of the Nam Theun 2, was funded by the Asian Development Bank (ADB) and completed in Theun . Global Lessons from the World Bank's Model Hydropower Project in Laos. Edited by Bruce Shoemaker and William Robichaud. New Perspectives in Southeast Asian Studies. Alfred W. McCoy, Ian G. Baird, Katherine A. Bowie, and Anne Ruth Hansen, Series Editors. “Extremely insightful and succinct, this volume shows how badly the Nam Theun 2 dam project has failed across . The purpose of this book is to share with development practitioners the ex - periences gained and lessons learned during the preparation of the $ bil-lion Nam Theun 2 (NT2) hydroelectric power project in the Lao People’s Demo cratic Republic. This book focuses on the project preparation exercise. In this context, the World Bank, seeking a means to once again finance large hydropower, put forward the Nam Theun 2 (NT2) hydropower project as a new, best-practice approach. Meanwhile, the International Hydropower Association (IHA) sought to counter the WCD with its own sustainability guidelines in and subsequently a Hydropower.

The Nam Theun-Hinboun hydropower project, a MW run-off river dam on the Theun River in central Laos, is the first of several large hydropower projects planned in the Theun-Kading River Basin in Laos. Launched in , construction has been completed and was officially opened in early (Shoemaker, ). Abstract – The fish diversity of the Nam Theun and Xe Bangfai drainages was surveyed between and 74 species are now recorded from the Nam Theun and from the Xe Bangfai drainages. Twenty-one (28%) of the Nam Theun species are endemic and 9 (5%) of the Xe Bangfai species. At the time of the respective surveys, 54 species were new.   The Nam Theun 2 Hydropower Project (NT2) is a trans-basin diversion power plant on the Nam Theun river in Khammouane and Bolikhamxay provinces in Lao People’s Democratic Republic. The $bn project was officially inaugurated in December The multi-purpose project was under construction for over a decade. The first hydropower plant Ubol Ratana in Thailand had start-up of turbine no. 1 on in By late 38 hydropower plants with installed power larger than 15 MW have been completed and in operation. Laos has the highest number of hydropower projects with 18 in Laos, followed by Vietnam with while there are 5 in Thailand.

  The price of US cents per kilowatt hour (kwh) for Nam Theun II and US cents per kwh for Nam Theun-Hinboun implies a premium of between % on existing Nam Ngum ( US cents per kwh) and Xeset prices. Nor do the sensitivity analyses on this crucial variable allow for a . The $ billion Nam Theun 2 (NT2) project would harness the power of the Nam Theun River. It required a trans-basin diversion of waters from the Nam Theun to a powerhouse at the base of the Nakai escarpment, and from there to the Mekong River.   The Asian Development Bank (ADB) approved funding today for the Nam Theun 2 Hydroelectric Dam Project, offering US$ million in loans and risk guarantees. The ADB joins the World Bank in funding.   The development of the Theun Hinboun Expansion proposals will further increase this figure by diverting more water from the Nam Theun basin upstream of the project" (Page ). "Similarly, increased diversion to the Hinboun by an expanded Theun Hinboun (including a storage on the Nam Gnouang) reduces generation flows at Nam Theun 1 and further.
