Hydropower is a kind of clean and renewable energy. It has been developing rapidly in China in recent years and has become China's largest clean energy source. However, hydropower generation highly dependent on natural hydrology, and directly determined by weather conditions. In recent years, extreme weather occurs more and more frequently, extreme droughts directly affect the hydropower generating ability, especially for hydropower rich areas, extremely draught weather can reduce hydropower generation and affect the power grid operation. Therefore, it is increasingly important to study the influence of extreme climate on hydropower generation to establish reasonable solutions to improve the power grid's ability to respond to such incidents. This study focuses on the hydropower generation at Yunnan, southwest China, with the total installed capacity of hydropower in this region is over 70%. In this study, we modeled and assessed hydropower generation at Yunnan under different climate scenarios. The results show that under extreme drought weather, the power generation of hydropower in Yunnan will be greatly reduced, which will seriously affect the Yunnan power supply. Therefore, Yunnan and other hydropower rich areas must establish strategies to ensure the normal supply of electricity under extreme climate conditions.
