Abstract: The present study investigates the performance of the Karun 4 reservoir power plant in Iran under the climate change impacts in the production of electric energy. The obtained results indicate an increase in temperature by 1.95°C to 2.34°C under RCP 4.5 and RCP 8.5, respectively. The reduction of the runoff entering the reservoir by the annual average of 19% (43%) under RCP 4.5 (RCP 8.5) is one of the other results of this study. A 9% (18%) decrease in total annual electricity production under RCP 4.5 (RCP 8.5) is the result of the power plant's performance.

Keywords: climate change; hydropower generation; TOPSIS; Karun 4 reservoir.
