This report identifies zones for cost-effective, equitable and environmentally sustainable energy development with wind, solar photovoltaic, and concentrating solar power in the countries of the Eastern and Southern African power pools. The approach employed for the study combines geospatial, statistical, energy engineering, and economic methods to comprehensively identify and value high-quality renewable resources for grid integration based on techno-economic criteria, generation profiles (for wind) and socio-environmental impacts.
