The first official assessments using the Hydropower Sustainability Assessment Protocol (HSAP) have been published on the Protocol website, the International Hydropower Association has announced.

The assessments, carried out over the last year, were undertaken on hydropower projects in Brazil (ESBR), Norway (Statkraft), Iceland (Landsvirkjun), and Germany (E.ON). The assessments were made by independent teams of experts, coordinated by IHA, and highlight areas in which the hydropower developers are performing well and where there is room for improvement. The publication of the reports now opens a period of 60 days of public comment, via the same website.

The Protocol, a comprehensive tool to assess the sustainability of hydropower projects globally, provides a rigorous, evidence-based assessment of between 19-23 relevant sustainability topics, depending on the development stage of the project. These topics include issues such as downstream flow regimes, indigenous peoples, biodiversity, infrastructure safety, resettlement, water quality, and erosion and sedimentation.

“The release of these results shows the detailed and expert nature of Protocol assessments, we hope that having reports available publicly will encourage other stakeholders in the sector to explore how assessments can be of use to them," commented Joerg Hartmann, Chair of the Protocol Governance Council.

Publication has been timed to coincide with the IHA World Congress taking place this week in Sarawak, Malaysia, with the goal of advancing sustainable hydropower. It is anticipated that a further five assessments will be published in the coming year.
