India's C&I renewable capacity to triple to 100 GW by 2032, storage to surge tenfold: Report
Synopsis
Key Takeaways
India's commercial and industrial (C&I) renewable energy capacity is projected to nearly triple — from 32 gigawatts (GW) in 2025 to as much as 100 GW by 2032 — while energy storage system (ESS) installations in the segment are set to leap more than tenfold to approximately 31 gigawatt-hours (GWh), according to a report released on Friday, 3 July 2025. The findings, published jointly by the India Energy Storage Alliance (IESA) and Customised Energy Solutions (CES), credit state-level regulatory innovation, corporate decarbonisation commitments, and surging grid tariffs as the primary drivers of the acceleration.
What Is Driving the Growth
The report identifies three converging forces behind the C&I clean energy surge. First, corporates across sectors are hardening net-zero and decarbonisation targets, pushing demand for on-site renewable generation and storage. Second, grid tariffs have risen sharply, making captive renewable power increasingly cost-competitive. Third, energy resilience — the ability to maintain operations during grid outages or supply disruptions — has become a boardroom priority, particularly for data centres, hospitals, and critical infrastructure.
State-level policy innovation is described as the decisive accelerant. Maharashtra's new renewable energy and storage policy now mandates energy storage for every new renewable project above 100 kilowatts (kW) in capacity. The same policy requires distribution companies to source 10 per cent of their electricity from storage by FY 2035–36. Gujarat, Karnataka, Tamil Nadu, and Rajasthan are also enabling faster adoption through cost-reflective banking, settlement policies, and transmission charge waivers.
Who Will Adopt Storage Fastest
Industrial facilities are expected to remain the single largest adopters of energy storage, accounting for more than half of all ESS installations by 2032. However, the fastest growth rate is projected in data centres and critical infrastructure — including hospitals, metro and railway stations, and airports — where uninterrupted power supply is operationally non-negotiable.
This is not merely incremental expansion; it represents a structural shift in how Indian industry views energy storage — from a backup measure to a strategic asset for both cost management and operational continuity.
What the Industry Said
Debmalya Sen, President of IESA, said the research signals a market inflection point. 'Our new research shows 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,' Sen said.
Where the Report Will Be Unveiled
The full report is scheduled to be formally released at India Energy Storage Week (IESW) 2026, running from 8 to 10 July at Yashobhoomi (IICC) in New Delhi. The event is expected to draw more than 200 exhibitors and over 10,000 industry leaders. Senior officials from the ministries of Heavy Industries, Mines, Power, Electronics, and Environment are scheduled to participate alongside state representatives and regulatory bodies. Discussions will focus on policy bottlenecks, state-level reforms, and actionable pathways for accelerating India's clean energy transition.
As India pushes toward its broader renewable energy targets, the C&I segment's trajectory will be a critical — and closely watched — indicator of whether policy ambition translates into installed capacity on the ground.
