The International Hydropower Association (IHA) is the global voice of sustainable hydropower. It is a non-profit membership organisation representing well over 100 members from every continent in the world.

Sustainable hydropower is a clean, green, secure, flexible, modern, and affordable solution for the energy transition. We believe that the world will need to at least double hydropower capacity in the next thirty years to support the massive increases in solar and wind power.

As an association, we believe that hydropower projects should be developed and operated responsibly and sustainably. Our members subscribe to the bold statement that going forward the only acceptable hydropower is sustainable hydropower.
