Adaptive Turbine Replacement Improves Hydropower Flexibility in a Changing Climate

Water Resources Research, Volume 62, Issue 8, August 2026.
Abstract Hydropower plants will operate under new conditions as water regimes shift, reservoir operating rules evolve, and the grid requires flexible balancing of wind and solar. Hydropower plant turbine systems are traditionally designed to operate at the highest efficiency within narrow ranges of flow and reservoir levels while deviations from design
