India's commercial and industrial (C&I) renewable energy capacity could increase from 32 GW in 2025 to as much as 100 GW by 2032, according to a report by the India Energy Storage Alliance (IESA) and Customized Energy Solutions (CES), which will be released during India Energy Storage Week (IESW) 2026.
The report, titled India Stationary Storage Market for C&I Applications: Insights Till 2032, also projects energy storage system (ESS) installations in the C&I segment to rise from current levels to between 28 GWh and 31 GWh by 2032, driven by increasing renewable energy adoption and evolving state-level policy frameworks.
According to the study, corporate decarbonisation targets, higher grid electricity tariffs, and growing demand for energy resilience are expected to drive the adoption of renewable energy and battery energy storage systems among industrial and commercial users.
State-level policy measures are identified as a key factor supporting deployment. Maharashtra's renewable energy and storage policy requires energy storage systems for new renewable energy projects above 100 kW. It sets a target for distribution companies to procure 10 per cent of electricity from storage by FY2035-36. The report also highlights policy support from Gujarat, Karnataka, Tamil Nadu and Rajasthan through measures such as banking provisions, settlement mechanisms and transmission charge waivers.
Industrial facilities are expected to account for more than half of total ESS installations by 2032, while data centres and critical infrastructure, including hospitals, airports, metro systems and railway stations, are projected to record the fastest growth in storage adoption.
The report notes that battery energy storage deployments are increasingly being used alongside open access renewable projects, rooftop solar installations and as alternatives to diesel generator-based backup systems. Lithium iron phosphate (LFP) batteries are expected to remain the dominant technology, while vanadium redox flow batteries and sodium-ion batteries are emerging as options for longer-duration storage applications.
"The numbers are compelling: tripling renewable capacity and a tenfold jump in storage installations by 2032. States like Maharashtra are setting new benchmarks, and the entire ecosystem now has the data needed to support the next phase of India's clean energy transition," said Vinayak Walimbe, Managing Director, Customized Energy Solutions.
The report will be officially released during India Energy Storage Week 2026, scheduled to be held from July 8-10 at Yashobhoomi in New Delhi, where policymakers, industry participants and technology providers are expected to discuss developments across India's energy storage and clean energy sectors.
