This action research project, Using Microfinance to Expand Access to Energy Services, looks at energy lending offered by a select number of MFIs on three continents—Asia, Africa, and Latin America. The objective is to document the opportunities, challenges, costs, and effects of integrating energy products into a MFI’s product mix, develop feedback for future expansions of these energy-lending products, and share the lessons learned with the industry at large. This study in the East Africa region examines in depth the energy lending of Faulu Kenya and KUSCCO, two MFIs with different approaches to offering loans to their clients for energy services and products, through field work and a desk/literature review. The field research included interviews with selected staff of the MFIs, energy suppliers, clients, and other energy stakeholders, and analysis of the MFIs’ lending programs and financial and accounting reports.
