Betting on Battery Storage: Africa’s BESS Market Forecasted to Grow 700% by 2030

Africa’s battery energy storage system (BESS) market is poised for a massive expansion, with installed capacity projected to grow by as much as 700% between 2025 and 2030. Driven by the need to offset aging thermal generation and a lack of gas infrastructure, the sector is benefiting from power market reforms and a significant drop in the cost of Chinese-manufactured components. South Africa currently leads the continent in project volume and capacity as developers target internal rates of return in the low to mid-teens.

Market intelligence firm Rho Motion forecasts that Africa’s BESS capacity could surge by 700% by the end of the decade, building on a current foundation of 28 projects exceeding 50 MWh. South Africa is the primary driver of this growth, facing a potential 14 GW firm supply deficit by the mid-2030s as coal capacity drops from 40 GW to 26 GW while peak demand climbs to 40 GW. Because gas-to-power ambitions remain largely unsecured due to supply constraints, the region is increasingly turning to renewables firmed by BESS. This shift is supported by a 66% drop in solar PV module prices between 2022 and 2024, alongside a record 15 GW of solar imports in the year leading up to June 2025, primarily sourced from the Chinese supply chain.

The evolution of African power markets from vertically integrated state utilities to competitive independent power producer (IPP) procurement is creating new routes to market for storage developers. While current structures are dominated by off-grid and behind-the-meter solutions, reforms are paving the way for energy exchanges, capacity markets, and ancillary services. Regional power pools like the Southern African Power Pool (SAPP) and Eastern Africa Power Pool (EAPP) are also working to facilitate cross-border trade, which improves system efficiency and reduces the need for country-level reserve margins. Developers are increasingly looking toward sophisticated offtake instruments, such as tolling and floor structures, to reallocate merchant risk and secure the commercial debt necessary for large-scale project financing.

Despite the optimistic growth projections, the African BESS sector faces significant regulatory and financial hurdles. Many jurisdictions lack liquid spot markets for energy trading, and some markets still penalize BESS assets with double charging by treating them as both demand and supply for grid network charges. Furthermore, financing remains a top challenge due to low credit ratings, currency volatility, and higher risk perceptions in emerging markets compared to Europe or the Americas. However, as regulators implement more favorable frameworks and the asset class demonstrates its ability to provide rampable security of supply, BESS is expected to become increasingly bankable and essential for closing the continent's energy supply gap.
