What we offer our members 

Better strategic collaboration  

We seek to understand the challenges facing sustainable hydropower and contribute to solving them. By engaging actively with our members, we understand their concerns and shape our priorities. 

Members are also able to directly influence IHA’s governance and work plan through their votes on strategic decisions and Board elections.  

Stronger global impact  

As the global voice of sustainable hydropower, IHA represents the industry in conferences, international forums, media, etc. At the same time, we recognise that our voice is strongest when we use it to reinforce a common message. Our members can count on us to help develop and promote this common message.  

Better energy policies and market incentives  

Through targeted engagements, IHA helps to improve the investment climate for sustainable hydropower. By working closely with national hydropower and renewable energy associations, IHA helps provide a holistic view of renewables, makes the case for better energy policies and promotes enabling market instruments. 

Better communication with the sector  

We understand that receiving and sharing information is key to the sustainability of our members’ business. We communicate through printed publications and our website (800,000 page views annually) as well as our online platform Hydropower Pro, where our members have access to specialised information from our knowledge networks. Through Hydropower Pro, our members have access to specialised discussions and industry-specific resources, as well as articles, case studies, publications and analysis.  

At IHA we do everything we can to facilitate meaningful conversations for our members. This includes arranging High-level roundtables where our members can speak with regional decision-makers, making sure that they know what events are going on through our knowledge networks, and organising regular virtual face-to-face events, trainings and consultations. 

More sustainable hydropower  

Sustainability is at the core of IHA’s work. Over the last two decades, IHA has worked together with a broad range of stakeholders to develop the Hydropower Sustainability Assessment Protocol and its associated ESG tools. We also help the hydropower community by developing industry-specific guidance notes such as the Climate Resilience Guide, tools to assess the greenhouse gas emissions of hydropower projects and training on sustainable hydropower.
