The global battery energy storage system (BESS) capacity is expected to continue to rise to manage growing demand from electrification, industry, and AI/data centres. Moreover, higher proportion of wind and solar increases intra-day variability, imbalance, and curtailment that batteries can mitigate economically. BESS additions are also driven by declining lithium-ion costs, stronger supply chains, and supportive policies. Against this backdrop, the global battery energy storage installed capacity is projected to see a sixfold rise at a compound annual growth rate (CAGR) of 42% from 2025 to 2030, says GlobalData, a leading intelligence and productivity platform.
