This presentation summarizes the key findings and strategic insights from Madagascar’s participation in the Energy Modelling Platform for Africa (EMP-A) 2025, focusing on geospatial electrification planning using the OnSSET tool. It outlines the national targets under the M300 initiative, aiming for 80% electricity access by 2030 with a strong emphasis on hydropower (75%) alongside solar, wind, and diesel technologies. The slides present electrification challenges in Madagascar—including limited data availability, human resource constraints, and infrastructure gaps—while proposing a least-cost technology mix as a planning tool. Scenario 1, based on cost-effectiveness, is identified as the most realistic pathway. The presentation also outlines future work, including improving the OnSSET model, integrating environmental impact assessments, and incorporating the tool into national capacity-building and planning processes.
