The Hydropower Sustainability Guidelines on Good International Industry Practice (HGIIP) define performance expectations for hydropower projects.

The 26 guidelines cover a range of environmental, social and governance topics. Each guideline presents definitions of the processes and outcomes relating to good practice in project planning, operation and implementation.

As a compendium, the guidelines are a reference document for meeting the expectations of lenders, regulators and communities. Compliance with the guidelines can be specified in commercial contracts between financiers and developers, and developers and contractors. Learn more.
