Renewable Energy Mapping: Small Hydro - Madagascar

The study will provide a thorough understanding of the potential small-hydro resources and their geographical distribution at the country level, overlaid with other key enabling factors and constraints, will inform land plan-ning decisions and contribute to the enhancement of the existing policy framework. An adequate policy fra-mework for RE combined with reliable and publicly-available resource data, are crucial ingredients in provi-ding commercial RE developers with the certainty they seek. Guidance on where RE development is both com-mercially viable and endorsed or encouraged by the res-pective regulatory authorities can help attract deve-lopers by highlighting investment opportunities, and can potentially save time by avoiding protracted, project-specific negotiations.
