Strategic Intelligence: Batteries in Power (2026)

Grid-scale battery energy storage systems (BESS) are emerging as a core piece of power-grid infrastructure as they make variable renewables, especially solar PV and wind, reliable and dispatchable.
Battery storage cumulative installed capacity is likely to keep rising because power systems increasingly need fast, deployable flexibility. At the close of 2025, the battery energy storage market achieved a cumulative deployment of 224.8GW and is estimated to reach 1,300GW by 2030.
China and the US are leading the global BESS market driven by renewable energy mandates, grid stabilization needs, and the rapid expansion of energy-intensive AI computing infrastructure. China and the US will account for a BESS power generation of about 793GWh and 382GWh, respectively, by 2030.
