Battery energy storage systems (BESSs) are becoming a key part of Africa’s transition to renewable energy, as it helps make the power grid more stable, flexible and secure across a continent that is still facing infrastructure and policy challenges, says renewable-energy company Enel Green Power. Battery systems are vital for connecting renewable sources, such as solar and wind, to national grids, with BESS technology providing the balancing power needed for renewables to meet increased electricity demand, without affecting grid reliability.
