The India Energy Storage Alliance (IESA), in partnership with Customized Energy Solutions (CES), will unveil its latest report, “India Stationary Storage Market for Commercial & Industrial (C&I) Applications: Insights Till 2032,” during the 12th edition of India Energy Storage Week (IESW), scheduled to take place from July 8–10, 2026 at Yashobhoomi (IICC), New Delhi.
According to the report, cumulative energy storage system (ESS) installations across India’s Commercial and Industrial (C&I) sector are projected to grow dramatically from less than 1 GWh in 2025 to between 23 GWh and 31 GWh by 2032. This represents an increase of more than 30 times over the forecast period, highlighting the sector’s rapidly expanding role in India’s energy transition.
The study identifies several key drivers behind this growth, including rising electricity tariffs, increasing demand for reliable and high-quality power supply, accelerated adoption of renewable energy, cost-optimization strategies by businesses, and the country’s broader decarbonization objectives.
Recognized as one of the world’s leading platforms for clean energy innovation and collaboration, India Energy Storage Week (IESW) 2026 will bring together stakeholders from across the e-mobility, battery manufacturing, battery recycling, stationary energy storage, and green hydrogen ecosystems.
As the flagship annual event of IESA, IESW 2026 is expected to attract more than 200 exhibitors and over 10,000 industry leaders, policymakers, technology providers, investors, and energy professionals from more than 30 countries. The event will serve as a key venue for industry networking, policy discussions, business partnerships, and knowledge exchange aimed at accelerating India’s clean energy transition.
Debmalya Sen, President of IESA, said, “India’s C&I energy storage market is at a pivotal moment. The sector is transitioning from backup and peak shaving to a strategic asset for energy optimisation, resilience, and decarbonisation. The insights from this report will help stakeholders shift from reactive power management to proactive energy leadership.”
The study details two growth scenarios: a Business-as-Usual (BAU) path, with ESS reaching 22-23 GWh by 2032, and a Rapid Adoption (RA) scenario, in which market-friendly reforms and technological advances could propel installations to 31 GWh. BAU assumes 5-6% annual C&I load growth and 15% RE CAGR; RA anticipates 18% RE CAGR, reflecting the impact of supportive policy and falling battery costs.
Vinayak Walimbe, Managing Director of CES, added, “With regulatory clarity, proven business models, and advanced storage technologies, C&I consumers can now make smarter, data-driven decisions that drive both cost savings and sustainability. Our study equips the industry with the actionable intelligence needed to capture this historic opportunity.”
Analysing the technology landscape, the report broadly covers lead acid, advanced lead acid, lithium-ion, vanadium-redox flow, sodium-ion, and pumped hydro storage systems, but specific technology analysis is focused on LFP, NMC, VRFB, and Sodium-Ion chemistries. LFP batteries currently dominate, with vanadium-redox flow and sodium-ion chemistries emerging for long-duration applications. The study also explores the shift from backup-centric to application-driven energy storage, with tailored BESS solutions increasingly deployed for open access RE projects, diesel generator (DG) replacements, and rooftop solar integration.
The report also features real-world case studies: 1) DG Optimisation with BTM BESS for Industrial Plant; 2) Solar & BESS at Scale is Replacing Diesel in India’s Leh; 3) Om Shanti Retreat Centre, Bhora Kalan, Gurugram, 2021. The results highlight that a BESS of 1-hour duration that can take over the average load during outage with higher cycling is a better proposition in terms of payback compared to a larger system that can handle peak loads but has less cycling. Additionally, Solar + BESS can structurally replace diesel even in remote, off-grid, high-altitude conditions. The current PPA tariff is conservatively priced, a modest revision transforms project economics decisively. These case studies highlight BESS viability in outage-prone, DG-reliant settings, where hybrid solar + storage enhances reliability and improves project economics.
It offers scenario forecasts, state-wise regulatory frameworks, technology benchmarking, and strategic recommendations for energy users, developers, investors, and policymakers.
