||This report constitutes a M.Sc. thesis carried out by master students Andreas Vinner and Erik Haastrup Müller at DTU Management Engineering. The thesis documents the identification of opportunities for offering a commercially sustainable power platform for third world rural villages in Sub-Saharan African regions. Thus, to avoid a concept with requirement of ongoing subsidies, the main focus has been on supporting productive use of electricity.
Necessary knowledge regarding appropriate system elements, the Sub-Saharan environment and rural living conditions was accumulated through literature studies, interviews with experts and a one-month field trip in Zambia and Malawi. The possible system elements in a solution were identified, described and evaluated.
Dimensioning of the installation was done from an electricity demand estimate, where possible users and their appliances were identified.
Ten concepts were created using a morphology based on the identified system elements. The most promising features from each concept were identified and these features were combined to create a final generic commercially sustainable concept. This concept is characterised by provision of a renewable source of electricity for productive uses, while still supporting rural development through lighting for community purposes and cooling of medicine. It was found that a sustainable solution is not possible with the current state of the technology, but it may be possible under the right circumstances in five years as long as the capital cost is heavily subsidised.
The described concepts in this thesis should enable implementers, financiers and other stakeholders to reconsider approaches for off-grid rural electrification. The thesis summarises existing experiences and provides new inspiration, which can hopefully lead to more widespread access to electricity.
