Global grid-connected battery energy storage system (BESS) installations have reached 156 GWh through October 2025, up 38% year-on-year compared to the same period in 2024, according to the latest data from Benchmark Mineral Intelligence’s Rho Motion.
China saw an increase of 27%, while Europe and North America both recorded growth of 21%. Remarkably, the rest of the world (ROW) saw a staggering 242% jump in deployment, highlighting a rapid acceleration in BESS adoption beyond traditional major markets.
In October, the global BESS market added 12.7 GWh of new capacity at grid level, an increase of 29% year-on-year. China led the gains, contributing just under 8.8 GWh of utility-scale BESS – up 72% from September – including a giga-scale vanadium flow battery.
