Sustainable Energy for Africa (SEFA) SEFA is a Multi Donor Trust Fund in the African Development Bank supporting sustainable energy solutions on the Continent. SEFA 2 will initially focus on three areas of intervention to scale-up investments in early stage markets and adapt to the needs of the emerging energy landscape: Green Mini Grids, Green Baseload and Energy Efficiency. SEFA will deploy resources through two financing windows: The technical assistance window, which will provide support for project preparation and enabling environment and the concessional investment window, which will provide catalytic risk capital and viability gap financing through the deployment of investment grants, intermediated junior equity, and concessional debt.
