New IDTechEx Report has the Commercial and Industrial Battery Storage Market Reaching US$21B Value by 2036
The demand for grid-scale battery energy storage systems (BESS) is increasing. Key Li-ion players dominate the energy storage (ES) market. Smaller players still have opportunities in untapped commercial and industrial (C&I) ES markets. A range of sectors in these opportunities include: data centers, telecommunication towers, electric vehicles (EVs), construction, agriculture, and mining. IDTechEx’s new market report, “Battery Storage for Data Centers, Commercial & Industrial Applications 2026-2036: Market, Forecasts, Players, Technology,” predicts the C&I battery storage market reaching US$21B in value by 2036. Technology developers will adapt to shifts in application demand and end-user requirements, considering battery storage cost, safety, and degradation.Â
Data center rollout, especially US Hyperscale data centers in the GW-scale, sets demand for C&I BESS to grow. Larger-capacity and longer-duration battery storage technologies provide improved grid flexibility, covering demand deficits in the electricity supply. Demand for C&I BESS in other applications and regions is expected, such as waves of China’s 5G and 6G tower deployment and on-site storage at private factories in Europe.Â
IDTechEx’s market report, “Battery Storage for Data Centers, Commercial & Industrial Applications 2026-2036: Market, Forecasts, Players, Technology,” provides 10-year market forecasts and a market analysis investigating individual players. IDTechEx gives a quantitative analysis of Li-ion cell cost differences in 2026, considering Li-ion tariffs, tax credits, foreign entity of concern (FEOC) restrictions, and material assistance cost ratio (MACR) thresholds. A clear Li-ion C&I BESS cost- component breakdown and US LFP cell plants being planned are also included.
Li-ion BESS flammability and cell degradation pose key disadvantages. Redox flow batteries (RFB), sodium-ion, second-life EV, and valve-regulated lead acid (VRLA) technology battery developers have a part to play with leveraged advantages such as RFB’s minimal degradation and non-flammable electrolyte. IDTechEx’s market report, “Battery Storage for Data Centers, Commercial & Industrial Applications 2026-2036: Market, Forecasts, Players, Technology,” analyzes an in-depth outlook on battery storage technologies for C&I applications, benchmarking Li-ion across Capex for C&I systems and showing key technical metrics.Â
