New Delhi: The India Energy Storage Alliance (IESA), in collaboration with Customized Energy Solutions (CES), is set to showcase the “India Stationary Storage Market for C&I Applications: Insights Till 2032” report at the 12th India Energy Storage Week (IESW), taking place July 8-10 at Yashobhoomi (IICC), New Delhi. According to the comprehensive new study, cumulative energy storage system (ESS) installations in India’s Commercial and Industrial (C&I) sector are projected to skyrocket from less than 1 GWh in 2025 to between 23 and 31 GWh by 2032, a more than 30X increase. The report attributes this exponential growth to rising electricity tariffs, the need for reliable, high-quality power, rapid adoption of renewable energy (RE), cost-optimisation demands, and India’s ambitious decarbonisation goals, according to a press release.
India Energy Storage Week (IESW) 2026, the definitive global platform for clean energy transition, will unite the entire value chain of e-mobility, battery manufacturing, recycling, stationary storage, and green hydrogen. As IESA’s flagship annual event, IESW 2026 will host over 200 exhibitors and 10,000+ industry leaders from more than 30 countries at Yashobhoomi (IICC), New Delhi, enabling high-impact networking, policy advocacy, and technical exchange.
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.
