Hydropower Sustainability Assessment Protocol. The Hydropower Sustainability Assessment Protocol (HSAP) is a global framework for assessing the sustainability of hydropower projects. The Protocol defines good and best practice at each stage of the life-cycle of a hydropower project across twenty-four environmental, social, technical and economic topics.

The Protocol was developed between 2007 and 2010 by a multi-stakeholder forum made up of representatives from industry, civil society, donors, developing country governments and financial institutions. The final version was published in 2010 after a trial period in sixteen countries. The Protocol was updated in 2018 to include good and best practice in climate change resilience and mitigation.

After the Protocol's launch, the governance entity of the Protocol approved the development of two additional tools derived from the HSAP, the Hydropower ESG Gap Analysis Tool (HESG Tool) to identify gaps against basic good practice and the Hydropower Sustainability Guidelines on Good International Industry Practice (HGIIP Guidelines), a reference document presenting definitions relating to good and best industry practice.

Application

Background 
The construction of a dam, power plant and reservoir creates social and physical changes in the surrounding area. As a result, hydropower projects can have both a positive and a negative environmental and social impacts.

The sustainability of the hydropower sector was the subject of a report by the World Commission on Dams in 2000. The HSAP was developed in response to the Commission's recommendations, as well as standards set out in the Equator Principles, World Bank Safeguard Policies, IFC Performance Standards and sustainability guidelines developed by the International Hydropower Association (IHA).

Purpose 

The Protocol is used by different hydropower stakeholders for different reasons:

 Independent review of sustainability issues
 Guiding improvement of sustainability practice
 Comparison with international best practice
 Communication with stakeholders
 Facilitating access to finance
 Preparing clients to meet bank requirements
 Reducing investment risk

Users 

Crédit Agricole, Societe Generale, Standard Chartered, Citi, and UBS now refer to the Protocol in their sector guidance.

The World Bank has analysed the value of the Protocol for use by their clients, concluding that it is a useful tool for guiding the development of sustainable hydropower in developing countries.

The International Institute for Environment and Development has reviewed social and environmental safeguards for large dam projects, concluding that the Protocol currently offers the best available ‘measuring stick’ for the World Commission on Dams provisions.

Process 

A Protocol assessment takes place over a one-week period at the project site and provides a rapid sustainability check.

A Protocol assessment does not replace an environmental and social impact assessment (ESIA), which takes place over a much longer period of time as a mandatory regulatory requirement. A Protocol assessment will, amongst other things, check the scope and quality of the ESIA which has been done.

To ensure high quality, all commercial use of the Protocol is carried out by accredited assessors. These assessors have significant experience of the hydropower sector or relevant sustainability issues, and have passed a rigorous accreditation course.

Scope

Tools 
The Protocol can be used at any stage of hydropower development, from the early planning stages through to operation.  Each project stage is assessed using a different tool: 
 The early stage tool, a screening tool for potential hydropower projects
 The preparation tool, which covers planning and design, management plans and commitments.
 The implementation tool, used through the construction phase.
 The operation tool, used on working projects.

Topics 
The Protocol covers a range of topics that need to be understood to assess the overall sustainability of a hydropower project.

Social aspects 

Communications and consultation
Project benefits
Project affected communities and livelihoods
Resettlement
Indigenous peoples
Labour and working conditions
Public health
Cultural heritage

Environmental aspects 

Environmental and social issues management
Biodiversity and invasive species
Climate change mitigation and resilience
Erosion and sedimentation
Water quality
Waste, noise and air quality
Reservoir planning / preparation and filling / management
Downstream flow regimes

Business aspects 

Governance
Procurement
Integrated project management
Financial viability
Economic viability

Technical aspects 

Demonstrated need and strategic fit
Siting and design
Hydrological resource
Asset reliability and efficiency
Infrastructure safety

The Protocol also includes ‘cross-cutting issues’ such as climate change, gender, and human rights, which feature in multiple topics.

Criteria 
For each sustainability topic, performance is assessed against a range of criteria at two levels: basic good practice and proven best practice.

History  
A multi-stakeholder forum developed the Protocol between 2008 and 2010.

The following key group were represented: social and environmental NGOs, governments of developed and developing countries, financial institutions, development banks, and the hydropower industry.

The forum jointly reviewed, enhanced and built consensus on what a sustainable hydropower project should look like.

Policies taken into account included the World Commission on Dams’ Criteria and Guidelines, World Bank Safeguard Policies, IFC Performance Standards, and the Equator Principles.

A draft of the Protocol was released in 2009, which was trialled in 16 countries across six continents and subjected to further consultation involving 1,933 individual stakeholders from 28 countries.

The final version was produced in 2010.

The diversity of the forum was important to ensure that the Protocol became globally applicable and universally accepted. Diversity also ensured that the multiple perspectives and stakeholder interests surrounding a hydropower project were incorporated into the document.

Governance  
The Protocol is governed by a multi-stakeholder body, the Hydropower Sustainability Assessment Council (HSA Council).

The mission of the Council is to ensure multi-stakeholder input and confidence in the Protocol's content and application.

All individuals and organisations engaged in hydropower are welcome and encouraged to join the Council. This approach to governance ensures that all stakeholder voices are heard in the shaping of the use of the Protocol and its future development.

The Council consists of a series of Chambers, each representing a different segment of hydropower stakeholders. Each chamber elects a chair and alternate chair for a two-year term. The chamber chairs come together regularly to form the decision-making Protocol Governance Committee.
