Deconstructing the concept of renewable energy-based mini-grids for rural electrification in East Africa

The goal of providing universal energy access to all by 2030 under the UN-led SE4ALL initiative calls for new and innovative solutions to rural electrification and is fuelling the recent interest in mini-grids. Mini-grid solutions are emerging as a third alternative to rural electrification, coming between the option of large-scale grid extension and pico-scale stand-alone solutions like solar home systems or solar lanterns. International expectations of mini-grids are high, with the International Energy Agency suggesting that they will play a significant role in reaching the goal of universal access. Based on a detailed review of past, ongoing, and planned mini-grids in East Africa, this study seeks to deconstructs the popular notion of mini-grids for rural electrification in East Africa. The study reveals that so far activities carried out under the heading of mini-grids to a large extent consist of the hybridization of existing utility-owned electricity systems for medium-size towns located far from the grid, which does not necessarily contribute to rural electrification. However, limited but increasing activity is identified regarding the use of mini-grids to bring electricity to rural villages and smaller rural towns. This is of specific interest because it is for this type of mini-grid that the main challenges are to be found with respect to identifying and testing adequate financing, ownership, and business models. Based on the trajectories identified for mini-grids for rural electrification and the challenges identified in the literature, the study concludes by proposing three avenues for further research.
