This study, commissioned by the Faraday Institution under the UK’s Transforming Energy Access (TEA) programme, explores how battery storage technologies can be viable and competitive in sub-Saharan Africa. In partnership with DNV GL, we explored the potential of battery systems replacing fossil fuel generator use. TFE performed value chain analyses of batteries and generators used in mini grids and small-scale behind-the-meter power generation across the continent. The report provides a comprehensive analysis of the current and future market opportunities for battery energy storage systems, emphasising their potential to support mini grids, captive power applications, off-grid industrial facilities, and grid-scale energy storage.
