About IHA

The International Hydropower Association (IHA) is a non-profit membership organisation and the voice of sustainable hydropower.

With members operating in over 120 countries globally, we provide trusted information and guidance on the sector to decision-makers and practitioners.

Our mission is to advance sustainable hydropower by building and sharing knowledge on its role in renewable energy systems, responsible freshwater management and climate change solutions.

We achieve this through research and policy development and championing good practices, training and project assessments.  


A trusted, credible voice

As the voice of sustainable hydropower, IHA provides trusted and credible information and guidance to decision-makers and practitioners.

We build and share knowledge through our strong partnerships with a broad range of stakeholders including governments and multilateral institutions, and civil society, finance, scientific and academic sectors

Informing policy on renewables

IHA advances strategies for integrating hydropower with fastgrowing variable renewables, helping to inform energy policymaking and improving the investment climate for sustainable hydropower projects.

Our knowledge building and advocacy increases awareness of hydropower’s importance to sustainable development, as well as the unique storage and flexibility services it provides to support the clean energy transition.

Recognising industry leaders

IHA’s members are recognised internationally for their commitment to planning, designing and delivering projects which support the Sustainable Development Goals and Paris Agreement on climate change.

The leading developers and operators, researchers and consultants and equipment suppliers among our membership have worked on many of the world’s most acclaimed hydropower projects, including the winners of the IHA Blue Planet Prize.

Setting industry standards

IHA champions continuous improvement and sustainable practices in the hydropower sector.

We advocate usage of the Hydropower Sustainability Tools, a set of good practice guidelines and tools for assessing project performance against objective environmental, social and governance performance criteria.

These tools are aligned with the World Bank and IFC performance standards and so help projects achieve good practice in hydropower development and secure investments.

Our training and capacity building courses are geared towards companies, professionals and consultants that wish to develop  projects that meet best practice, or report on their sustainability performance.

Sector monitoring and statistics

IHA monitors national and regional policy developments and data. 

We foster and coordinate scientific research and industrial innovation which seeks to address the most pressing challenges facing the hydropower sector.

Our in-house experts provide regular, exclusive briefings on news developments, sector trends and international good practices through our online community Hydropower Pro.

The Hydropower Status Report, our flagship publication, is the world’s most authoritative source of global hydropower installed capacity and generation data.
