  abstract = {{C}limate change ({CC}) and variability impacts on hydroelectric generation have become critical for hydropower management. {T}he trends of inflow, outflow, reservoir water level, and storage as well as hydraulicity indices of three main dams in {C}ote d'{I}voire, namely {K}ossou and {T}aabo in the {B}andama basin and {B}uyo in the {S}assandra basin were examined during 1981-2017 and their impacts on hydropower generation were analyzed. {M}oreover, the hydropower generation sensitivity to {CC} of these dams was assessed using statistical analysis. {T}he results reveal that the inflow is highly dependent on rainfall while the water level is highly influenced by the outflow, which is a function of the inflow to the reservoirs and water management policy. {F}urthermore, the {M}ann {K}endall test revealed that temperature and potential evapotranspiration have increased significantly in all three sub-basins while precipitation shows a significant upward trend only within the {T}aabo dam catchment area. {M}eanwhile, inflow to reservoir increased significantly and greatly than precipitation probably due to land use/cover change. {P}recipitation and inflow show a strong correlation as energy generation is significantly and strongly correlated to outflow (inflow) in all stations (except {K}ossou). {F}urthermore, the energy generation at {B}uyo and {T}aabo dams is more sensitive to reservoir inflow, while that of {K}ossou dam is more affected by water level. {I}n addition, the power of a given year is also dependent on the total rainfall of that year and/or the previous year depending on the plant.},
