| Summary: | - Large dams affect upstream and downstream ecosystems and livelihoods
- Dam reoperation can in principle reintroduce a near natural flow regime while increasing overall annual hydropower production but it requires significant adjustments elsewhere to cope with the seasonal variability in energy supply
- The feasibility of reoperating a dam is therefore dependent on a balance of trade-offs between technical, economic and social benefits and challenges
- For the Akosombo and Kpong dams, reoperation is not economically and socially feasible, it is therefore more cost effective to focus instead on improving alternative livelihood sources |
