Hydropower makes it an important contributor to Vietnam’s energy’ grid, accounting for about 40% of the. total national electricity’ production. However, hydropower generation is very sensitive, to changes and variability’ in climate variables, particularly rainfall and evaporation. Climate, change, which substantially impacts climate, variables and runoff, has a significant influence on the. Inflows to reservoirs at hydropower plants, and their hydropower generation. Therefore, this study aims to conduct a quantitative, assessment o f the. climate, change, impact on the. future, hydropower production, demonstrated for the. Thac Mo hydropower Project. This study uses a GR4J hydrological model coupled with a hydropower simulation model to simulate, future, inflow and hydropower generation at the. hydropower plant under climate, change. Six Regional Climate. Models (RCMs) from The. Coordinated Regional Downscaling Experiment (CORDEX) with two representative concentration pathways (RCP2.6 and RCP8.5) scenarios are. bias-corrected by quantile, mapping method to project changes in future, rainfall and temperature for the. study area. Our quantitative, assessments indicate, that climate, change, is expected to alter the. rainfall regime, decrease the. average, annual inflow and hydropower generation by 20 - 40% by the middle, o f the 21st century.
