A new report by the India Energy Storage Alliance (IESA) and Customized Energy Solutions (CES) projects India’s C&I renewable energy deployments to rocket from 32 GW in 2025 to as much as 100 GW by 2032. The research, set for release at the India Energy Storage Week (IESW) 2026, also forecasts that energy storage system (ESS) installations in the C&I segment will grow more than tenfold, reaching up to 31 GWh over the next seven years.
“India’s C&I energy storage market is not just growing; it’s accelerating toward a new era. With forward-thinking state policies and rising corporate demand, storage is becoming a strategic tool for resilience and decarbonization, not just backup. The momentum we’re seeing now will define the sector for the next decade,” said Debmalya Sen, president of IESA.
The report, “India Stationary Storage Market for C&I Applications: Insights Till 2032,” attributes this explosive growth to ambitious corporate decarbonization efforts, soaring grid tariffs, and a rising need for energy resilience.
State-level regulatory innovation is also paving the way. Maharashtra’s newly announced renewable energy and storage policy leads the charge, mandating energy storage for every new RE project above 100 kW and requiring DISCOMs to procure 10% of their electricity from storage by FY 2035-36. States like Gujarat, Karnataka, Tamil Nadu, and Rajasthan are also enabling rapid adoption with cost-reflective banking, settlement policies, and transmission charge waivers.
Vinayak Walimbe, managing director of Customized Energy Solutions, said, “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, from industry to policymakers, now has the data and clarity needed to seize these opportunities and drive India’s clean energy transition.”
Industrial facilities are set to remain the largest adopters of energy storage, accounting for over half of all energy storage system installations, while data centres and critical infrastructure, such as hospitals, metro and railway stations, and airports, will see the fastest growth.
The study finds that the C&I market is shifting from simple backup power to application-driven storage, with tailored BESS solutions deployed for open access renewables, diesel generator replacements, and rooftop solar integration.
The technology landscape is evolving as well, with lithium iron phosphate (LFP) batteries dominating, and vanadium-redox flow and sodium-ion chemistries emerging as alternatives for long-duration needs.
India Energy Storage Week (IESW) 2026, to be held from July 8-10 at Yashobhoomi (IICC), New Delhi, will bring together 200+ exhibitors and over 10,000 industry leaders, providing a platform for policy discussion, technical exchange, and showcasing innovation across the clean energy value chain.
