Statistics and knowledge
IHA monitors the growth of hydropower in all regions of the world.
Our analysts keep IHA members informed of key trends and developments throughout the year with authoritative publications and exclusive briefings.
The research and statistics which feature in these reports are drawn from year-round sectoral monitoring, surveys of members and governments, and from IHA’s own hydropower database.
As a global association we need global information to provide the fullest possible picture of the industry and to advance the case for sustainable hydropower.
At the heart of this is IHA's hydropower database, which holds data for over 8,000 individual hydropower stations of above 1 MW capacity. This representing about 90 per cent of global capacity, as well as company and national data.
The database has been built in collaboration with regulators, ministries and electricity associations, as well as the world's station owners and operators to serve as a resource for the industry.
We will continue to increase the number of stations covered, and extend the depth of information for each station and the policy environments in which they operate. We are keen to work with other data holders to advance our common understanding.
Hydropower Status Report
Our flagship publication, the Hydropower Status Report, presents the latest global hydropower statistics by country and by region.
The 2017 report found a total of 31.5 GW of installed capacity was added worldwide during the previous year. This figure includes 6.4 GW of new pumped storage, nearly double that added the previous year.
The report featured a map of major transmission developments worldwide and 17 country profiles, as well as a broader range of topic analyses.
IHA members can participate in one of our knowledge networks, which bring together hydropower professionals to share ideas and experiences, discuss new developments and collaborate on a range of topics. Read more.
Through this work, we seek to build and share knowledge about the hydropower sector for industry, the general public, NGOs, international organisations and research institutes.
We aim to ensure that hydropower data is accurately represented in international energy, water, and climate publications. We also monitor technological innovations and policy developments relevant to hydropower.
From this information we have developed a series of interactive maps to make some of this data available in an easy to view format.
