In December 2025, more than 65 GWh of grid scale battery energy stationary storage (BESS) entered operation in China. This exceeded the total installed in the US for the whole of 2025 by more than 15GWh. These systems store electricity from wind, solar, and other clean power and help keep grids stable when demand rises. When energy is needed, it is released from the BESS to power demand to lessen any he integration of demand- and supply-side management. After a historic 2025, when global BESS capacity surpassed 250 GW and overtook pumped hydropower, momentum is set to accelerate in 2026.
