About the tools


The Hydropower Sustainability Assessment Protocol promotes and guides more sustainable hydropower projects. It provides a common language which allows governments, civil society, financial institutions and the hydropower sector to evaluate sustainability.

The HSAP offers a way to assess the performance of a hydropower project across more than 25 sustainability topics. Assessments are based on objective evidence and results are presented in a standardised way, enabling better understanding of how existing facilities are performing and how well new projects are being developed.


The Environmental, Social and Governance Gap Analysis Tool (HESG Tool), based on the framework of the HSAP, is designed to identify gaps against good practice and provides an action plan to help project teams address these within a reasonable timeframe. It is divided into 12 topic sections which are compatible with IFC Environmental and Social Performance Standards and the World Bank’s Environmental and Social Framework.

Both tools were developed by the International Hydropower Association (IHA) in partnership with the Hydropower Sustainability Assessment Council, which is formed of social and environmental NGOs, financial institutions, governments and hydropower companies.

How much does it cost? 

The standard rate for the training course is £4,500+VAT.

IHA members and Protocol Council Chamber Members can benefit from a discounted rate of £3,825+VAT.
