1.1 Development History
The NNP1 Hydropower Project was identified in the early 1990s and a preliminary Feasibility Study (FS) was conducted by SOGREAH Consultants with funding from the French government in
1991. An MOU was signed between the Government of Lao (GOL) and Shlapak Group of USA in 1991 but was cancelled in 1996. As the request of the GOL, Japan International Cooperation Agency
(JICA) through Nippon Koei (NK) conducted a new FS of the Project in two phases, 1998-2000 (Phase1: focus on environmental impacts) and 2001-2002 (Phase2: focus on technical and
commercial aspects). The FS submitted to GOL in November 2002, confirmed the feasibility of the Project on a Built-Operate-Transfer (BOT) basis and recommended the optimal development
plan of the Project based on physical, economic and safeguard considerations.
After the FS, NK as an investor concluded the MOU with GOL to implement a further study of the Project in May 2003. During the term, KANSAI joined the study, KANSAI and NK made a review report in May 2004. After the negotiation with GOL, KANSAI and NK signed the Project Development Agreement (PDA) on 27th April 2006 for the further development of the Project.
