A year ago, a solar mini-grid in the Nigerian village of Sabangida provided nearly uninterrupted power to half of the community’s homes and businesses. This has led to the growth of clean energy mini-grids, with rural Africa set to benefit the most. The World Bank and the International Energy Agency consider solar minigrids a viable way to provide fossil-free electricity to rural areas in sub-Saharan Africa. However, scaling up solar in Africa faces challenges such as securing investors, inflationary pressures, better state financing and clear policies.
