Innovative technologies related to small scale hydropower 

Objective of this Task

The purpose of this sub-task was to collect and disseminate practical information for the development of new hydropower plants and the upgrade of existing facilities. Recent innovative hydropower installations and equipment were surveyed and evaluated based on their capability to expand the potential for small hydropower development, improve the equipment efficiency and to ensure conservation and protection of the environment.

Survey of Innovative Technologies

Technologies were identified by conducting a literature review of international publications and conferences (Hydro, Hydroenergia, HydroVision, Waterpower etc.) and based on the recommendations of Annex-2 members at that time. (Canada, Norway, and Japan). 

These technologies were selected and categorized based on the key categories identified in Table-1. The technologies were described according to the following aspects: (1) Technological Classification (2) Technical Characteristics (3) Scope of Applicability (4) Results of Application. See the Summary Report for details.

Collection and Evaluation of Innovative Technologies

Those technologies selected as innovative were not necessarily new. The selected innovative technologies were classified by key category and evaluated for their applicability with regard to the following;

Contribution to Cost Reduction	Improvement of Efficiency
Improvement of Reliability	Enlargement of Applicability
Support to Operation and Maintenance	Mitigation of Environmental Impact

 

 

 

The technologies and their evaluation are summarized and documented in a simple and easy-to-search downloadable Excel data sheet format. See the full list below.

Future contributions

In this sub-task, we were able to collect information on 31 valuable innovative technologies that overcame identified challenges for new development or the renewal of existing small hydropower facilities. However, it is clear that further innovation in all areas of technology development will be required. 

We encourage ongoing contributions to this data base. Please contact the IEA Hydro Secretary if you wish to make a submission.
