We are currently undertaking a major scoping study to assess the needs and opportunities for financial support to scale-up electricity access in Sub-Saharan Africa through off-grid clean energy solutions. Together with our project partners Frankfurt School and TTA, we are developing a multi-layer index that will allow investors to assess the best technology solutions and business models in at least eight countries: Benin, Cote d’Ivoire, Ethiopia, Ghana, Mozambique, Senegal, Uganda, and Zambia. The costs-benefits-analysis includes indicators aiming at the assessment of current and future power demand; local market readiness; policy and regulatory frameworks; as well as financing needs and existing support mechanisms. The findings will inform the design of a financing programme to support energy access through small and medium scale clean energy solutions from stand-alone systems to mini-grids.
