The IEA provides support for international collaboration on energy technology R&D, deployment and information dissemination. These groups function within a framework created by the IEA - the International Framework for International Energy Technology Collaboration. The views, findings and publications of these international groups (formally called Implementing Agreements) do not necessarily represent the views or policies of the IEA Secretariat or of all its individual member countries. OECD Member countries, autonomous OECD non-member countries, intergovernmental organisations, non-governmental organisations and private sector entities may participate. For more information, see our Technology Agreements page.


The IEA Hydropower Agreement is a working group of governments and industry which intends to provide objective, balanced information about the advantages and disadvantages of hydropower.

Signatories : Australia | Brazil | China | Finland | France | Japan | Norway | United States |

Current Projects (Annexes)

Annex II. Small Scale Hydropower
Address technological, organisational and regulatory issues related to small hydro projects (less than 10MW and more than 50KW).


Annex VIII. Hydropower Good Practices (now in Dissemination Phase)
Develop training materials in the areas of planning, operations and maintenance of hydropower installations, making use of latest information technologies to disseminate its results.


Annex X. Integration of Wind into Hydropower Systems
The Hydropower Annex X works jointly with the Wind Implementing Agreement's Wind/Hydro Annex, to undertake research and studies on such issues as integration, hydrologic impacts, market and economic issues and simplified modeling of wind-hydro integration potential. Some key issues of specific interest to hydropwer generators include the simulation of water resource, reservoir storage and wind forecasting to opimise utilisation, social and environmental issues arising from integration and the value of the ancillary services that hydropower can provide. While integration of wind energy (new and existing developments) into existing hydropower and other systems is the initial focus of the Annexes, the Hydropower group will also consider the synergies of developing new hydropower in joint hydro-wind developments.


Annex XI. Renewal and Upgrading of Existing Hydropower Plants
The purpose of this Annex is to provide useful information to facilitate decision-making on the renewal and upgrading of existing hydropower facilities, through the presentation and analysis of relevant case histories covering good practice.


Annex XII. Hydropower and the Environment
The objectives of the comprehensive work program under this Annex are to: - increase knowledge of the processes - establish guidelines for planning studies on the carbon balance in reservoirs - standardize GHG flux evaluation methods. Guidelines will issued in 2 volumes: Volume 1: Guidelines for the Quantitative Analysis of Net GHG Emissions from Reservoirs Volume 2: Modelling
