A joint research report from the India Energy Storage Alliance (IESA) and Customized Energy Solutions (CES) forecasts dramatic expansion in India’s commercial and industrial (C&I) renewable energy and energy storage segments through 2032, set to be officially unveiled at India Energy Storage Week (IESW) 2026 in New Delhi.
Titled India Stationary Storage Market for C&I Applications: Insights Till 2032, the report projects India’s C&I renewable energy installations will jump from 32 GW in 2025 to a maximum of 100 GW by 2032. Over the same seven-year timeframe, C&I energy storage system (ESS) deployments are expected to multiply more than ten times, hitting 31 GWh.
Debmalya Sen, President of IESA, highlighted robust sector momentum driven by progressive state policies and mounting corporate clean energy demand. He noted energy storage has evolved beyond basic backup power into a core strategic asset for grid resilience and corporate decarbonization, laying the groundwork for the industry’s growth trajectory over the next decade.
Three core factors fuel the sector’s explosive growth: aggressive corporate decarbonization targets, climbing grid power tariffs, and surging industrial demand for reliable energy supply. Forward-looking state regulatory frameworks further accelerate market uptake. Maharashtra’s new renewable and storage policy stands out by mandating storage integration for all new renewable projects exceeding 100 kW and requiring power distribution firms (DISCOMs) to source 10% of power from energy storage by fiscal year 2035–36. Gujarat, Karnataka, Tamil Nadu and Rajasthan also roll out supportive measures including cost-aligned energy banking rules, flexible settlement mechanisms and transmission charge exemptions.
Vinayak Walimbe, Managing Director of Customized Energy Solutions, commented the landmark growth figures signal clear opportunities for the whole clean energy ecosystem. State policy benchmarks and concrete market data equip manufacturers, developers and regulators to advance India’s national clean energy transition.
Industrial plants will remain the largest single adopter of C&I storage, representing more than half of total ESS deployments. Meanwhile, data centres and critical infrastructure assets—including hospitals, metro and railway stations, and airports—will register the fastest storage uptake growth.
The C&I storage market is undergoing a functional shift away from standalone backup power toward multi-scenario application-specific battery energy storage systems (BESS). Customized BESS products are widely deployed to support open-access renewable power, replace polluting diesel generators and integrate rooftop solar assets.
On the technology front, lithium iron phosphate (LFP) batteries dominate the current market landscape. Vanadium redox flow batteries and sodium-ion batteries are emerging as viable alternatives to meet long-duration energy storage requirements.
