Runner optimization for climate-related changes in the operation of hydro plants

Climate change is increasingly impacting hydro plants, posing significant challenges such as greater sediment load, erosion, and cavitation issues. The runners of turbines, in particular, are exposed to increasing loads of various kinds. This paper demonstrates how customised runners, designed during refurbishment projects, can effectively mitigate these challenges and enhance plant performance. All the plants discussed are located in Türkiye, a region where the effects of climate change are becoming more pronounced.
