Nam Oucasgade Hydropower Project

Project Introduction

Nam Ou – First Phase Power Project in Lao P.D.R

As the largest tributary of Mekong River In northern Laos, Nam Ou River, with typical feature of mountain stream, is located in the plateau region from Luangprabang, the second largest city in Laos, to the border of Yunnan Province in China. Nam Ou River has entire drainage area of 26079 Km2, with 475 Km in length and an average gradient of approximately 2.5 %. It is planned to adopt the “two reservoir & seven-cascade “development proposal, and the investment and construction work will be divided into two phase project (Nam Ou 2, 5 & 6 ) has a total install capacity of the cascade hydro power Project is 1,156 MW, and average annual energy output is 5046 GWh. The first phase project ( Nam Ou 2, 5& 6 ) has total install capacity 540 MW, with an average annual energy output of 2114 GWh ( 2092 GWh net of the energy loss ) under joint operation of all cascade, and total investment of USD 1.035 X 109 . The development of second phase project ( Nam Ou 1, 3, 4, 7 ) will be undertaken at appropriate time depending on the circumstances of energy market in Laos.

            Nam Ou 2 HPP has a total install capacity of 120 MW and average annual energy output of 484 GWh. The reservoir has a normal water level of 325 m with a capability of daily regulation
