Results suggest that the Grand Inga project will be resilient to negative climate impacts during its initial phases (1-5). The system demonstrates security and insensitivity to adverse changes, both for existing (Phase 1-2) and planned (Phase 3-5) hydropower components. The study indicates that climate change effects become apparent only in later phases (6-8), with predominantly positive impacts, potentially increasing the generation potential of the hydropower system. Overall, the Grand Inga hydropower project appears robust against adverse climate influences throughout the majority of its development phases.
