Battery energy storage market projected to reach US$ 118.4 billion by 2033

The battery energy storage systems (BESS) market is undergoing a structural shift, moving from a supporting role for renewables to a critical asset class that determines the commercial viability of renewable energy projects. The market is projected to grow from US$ 58.5 billion in 2026 to US$ 118.4 billion by 2033, representing a compound annual growth rate (CAGR) of 10.6%. Key trends include the dominance of lithium iron phosphate chemistry in utility-scale installations and the emergence of four-hour duration systems as a commercial baseline for grid services.

In Japan, GATES Inc. has announced its entry into the low-voltage grid-scale battery storage market, timed with regulatory changes expected in April 2026. The company aims to utilize idle land and commercial parking spaces to integrate energy infrastructure, supporting decarbonization and regional disaster resilience. GATES Inc. has formed alliances with several professional firms, including Green Energy Plus and Deloitte Tohmatsu LLC, to conduct feasibility studies and manage project execution.
