This is an internal status report to ESMAP and Gesellschaft fur Technische Zusammenarbeit (GTZ) which summarizes their ongoing work under a joint energy study entitled INGENS - Income Generation through Energy and. Complementary Services. INGENS has proposed (and started to test) a pragmatic, low-cost approach to improve impact evaluation for future electrification programs: a simple Add-on Electricity Impact Evaluation Instrument (AddIE) for the specific case of firm level productivity which shall be applicable to a broad range of electrification programs (EP), and cost well under US00k per EP. This tool allows EP managers to move from simple monitoring and reporting of numerical targets achieved to evaluation of the (pro-poor) impact achieved among an important segment of the target group. Five countries were studied: Benin, Ghana, Nigeria, Uganda, and South Africa. This report discusses the overall results of the studies and lessons learned. Finally, it presents next steps and a funding request. There are five annexes at the end of the report, including the questionnaire used, case examples, pictures, and the budget for future funding.
