India's renewable capacity to hit 100 GW and storage set for 10x surge by 2032

 

India’s commercial and industrial (C&I) sector is poised for a dramatic clean energy transformation, with renewable energy capacity expected to triple from 32 GW in 2025 to 100 GW by 2032, according to a landmark report.

 

The study by the India Energy Storage Alliance (IESA) and Customized Energy Solutions (CES) also projects a more than tenfold increase in energy storage system (ESS) installations, reaching up to 31 GWh over the next seven years.

 

The findings, to be unveiled during India Energy Storage Week (IESW) 2026, underscore the rapid acceleration of renewable energy and storage adoption as businesses seek to cut costs, strengthen energy security, and meet decarbonization targets.

 

India Energy Storage Week (IESW) 2026, to be held from July 8-10 at Yashobhoomi (IICC), New Delhi, will bring together more than 200 exhibitors and over 10,000 industry leaders, serving as a key platform for policy discussions, technology exchange, and innovation across the clean energy ecosystem.

 

Senior officials from the Ministries of Heavy Industries, Mines, Power, Electronics, and Environment, along with state representatives and regulatory bodies, are expected to participate in discussions focused on policy bottlenecks, state-level reforms, and industry priorities aimed at accelerating India's clean energy transition.

 

Debmalya Sen, President of IESA, said, “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.”

 

The report, India Stationary Storage Market for C&I Applications: Insights Till 2032, attributes the projected growth to a convergence of powerful market drivers, including ambitious corporate sustainability commitments, rising electricity tariffs, and growing demand for reliable power.

 

State policy reforms are emerging as a major catalyst. Maharashtra has taken the lead with a new renewable energy and storage policy that mandates energy storage for all new renewable energy projects above 100 kW and requires DISCOMs to source 10% of their electricity from storage by FY 2035-36. 

 

Gujarat, Karnataka, Tamil Nadu, and Rajasthan are also driving adoption through measures such as cost-reflective banking, improved settlement mechanisms, 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.”

 

The report identifies industrial facilities as the largest users of energy storage, accounting for more than half of all ESS installations by 2032. Meanwhile, data centres and critical infrastructure—including hospitals, metro and railway stations, and airports—are expected to record the fastest growth.

 

The study also highlights a shift in the market from conventional backup power to application-specific battery energy storage systems (BESS), supporting open access renewable energy, replacing diesel generators, and integrating rooftop solar. 

 

Lithium iron phosphate (LFP) batteries are expected to remain the dominant technology, while vanadium-redox flow and sodium-ion batteries are emerging as promising options for long-duration energy storage.

 

The IESA-CES report is expected to provide policymakers, developers, and industry stakeholders with critical market intelligence as India's C&I sector positions itself at the forefront of the country's next phase of clean energy and energy storage growth.
