Thank you for your contributions. Very good points!
Paying for electricity might need some local development and information sharing however, these rural communities will want the benefit that electricity brings and therefore will be willing to partake in such programs. As with mobile communication in our region, the challenge will be to find strong business models where the initial investment will not be encumbered. Mobile operators in Africa find it difficult to invest into rural Africa due to investment criterion not being met and is always looking for solutions that require less capital investment. Revenue per user always decline rapidly the more these networks expand into rural areas and therefore placing a burden and slowing down the process to provide communication to rural Africa.
Mini-grids is a good initiative however to make this model work for the long term, these deployments must coincide and con-exist with other industries i.e. mobile networks, mining, forestry etc. From a strong and sustainable base these min-grid deployments can expand and offer electricity access to rural Africa.
You are describing Yiitidi's business model. As you say, minigrid requires an anchor to which sell the bulk of the production. But then, SLA require excess capacity that can be monetized by selling it to a microgrid, providing the so much needed electricity to households and small businesses. Specially the business have load requirements which exceed by far the capacity of standard PAYG systems.
