Project Description
Climate Change Impact Assessment of the Proposed Nam Ngiep 1 Hydropower Project
The Project is designed as a hydropower facility, and the main dam and reservoir are not designed for flood control. The overall objective of the study was to assess the climate risk of the proposed Nam Ngiep Hydropower 1 Project (NNP1) in Lao PDR, and to identify measures to increase its climate resilience.
The first of its kind on a hydropower facility in Lao PDR and the Mekong, the study (i) assessed the impacts of climate variability and projected climate change on key parameters of the Project, including infrastructure, future runoff, sedimentation, dam safety, over-topping of concrete dam and earth-fill, and energy production; (ii) estimated the potential costs of these impacts; and (iii) presented the results of the assessment to the Borrower, ADB and other relevant stakeholders on the implications of the impacts of climate change on the project.
