Press Releases

According to IMARC Group's report titled "India Energy Storage Systems (ESS) Market Size, Share, Trends and Forecast by Technology, Application, End User, and Region, 2026-2034", The report offers a comprehensive analysis of the market, including market forecast, growth, Share, and regional insights.

India’s transition toward 500 GW of non-fossil fuel capacity by 2030 is aggressively catalyzing the deployment of advanced energy storage systems to secure round-the-clock grid resilience. For corporate energy stakeholders and infrastructure investors, this presents a rapidly scaling asset class driven by massive utility procurement and industrial decarbonization.

• The India energy storage systems (ESS) market size reached a capacity of 8.9 GW in 2025 and is projected to scale heavily to 16.2 GW by 2034.
• The sector is forecast to exhibit a solid 6.84% CAGR from 2026 to 2034, structurally driven by the necessity to mitigate the intermittency of solar and wind power generation.
• Electrochemical storage is experiencing rapid growth, with national lithium-ion battery demand anticipated to escalate from approximately 15 GWh in FY2024 to an estimated 127 GWh by 2030.
• Utility-scale pumped hydro storage remains the dominant technology, capturing the largest market share as public and private entities inject large-scale capital to fortify baseload grid stability.

Industry Trends

• Mainstreaming of Energy Storage in Grid Operations: Under the amended Electricity Rules, Energy Storage Systems (ESS) have been explicitly recognized as a core component of the national power system, enabling their active participation across generation, transmission, and distribution functions. The Central Electricity Regulatory Commission (CERC) has allowed storage-based resources to provide real-time grid balancing and ancillary services, including secondary and tertiary reserves. Furthermore, electricity supplied from Battery Energy Storage Systems (BESS) is now permitted to participate in the High-Price Day-Ahead Market, allowing storage developers to respond to peak price signals.
• Standardization of Safety and Construction: The Central Electricity Authority (CEA) is actively establishing a formal technical and regulatory framework for storage technologies. In early 2026, the CEA notified the Measures Relating to Safety and Electric Supply Amendment Regulations, alongside specialized Technical Standards for Construction of Electrical Plants, specifically to mandate robust safety, design, and construction frameworks for large-scale BESS deployments.
• Prioritization of Off-Stream Pumped Storage: There is a definitive regulatory shift toward closed-loop, off-stream Pumped Storage Projects (PSPs). To accelerate deployment, the Government of India has entirely exempted off-stream closed-loop PSPs from the requirement of CEA concurrence, regardless of the project's capital expenditure.

Market Growth Catalysts

• Expansion of the Viability Gap Funding (VGF) Scheme: The Union Cabinet’s VGF scheme acts as a massive demand catalyst. Acknowledging the recent decline in global battery prices, the government dramatically scaled the supported capacity of the scheme from 4,000 MWh to 13,200 MWh while staying within the originally approved budgetary allocation. The revised VGF provides up to 30% of capital costs (capped at ₹46 lakh per MWh), significantly lowering the financial barrier for developers.
• Inter-State Transmission System (ISTS) Waivers: To heavily incentivize the integration of storage with renewable energy, the government has implemented a 100% ISTS charge waiver. This critical cost-reduction measure applies to standalone BESS projects commissioned by June 2025. To promote hybrid solutions, the 100% waiver has been extended up to June 2028 for co-located BESS projects, as well as for co-located PSPs where construction is awarded by June 2028.
• Resource Adequacy Mandates and PLI Backing: The government has issued guidelines mandating state utilities to prepare dynamic 10-year Resource Adequacy Plans, formally incorporating energy storage as a mandatory planning resource to meet peak demand. On the manufacturing side, the Ministry of Heavy Industries is driving localized production through an ₹18,100 crore Production-Linked Incentive (PLI) scheme for Advanced Chemistry Cells (ACC), which explicitly earmarks 10 GWh of manufacturing capacity for grid-scale stationary storage.

Competitive Landscape

• Tariff-Based Competitive Bidding (TBCB): The competitive procurement of large-scale storage is strictly governed by the government's recently notified TBCB guidelines for both BESS and PSPs. These guidelines create a transparent, price-driven mechanism that standardizes power purchase and capacity tolling agreements for central and state-level procurement.
• Mandatory Domestic Content Requirements (DCR): A major structural shift in the competitive ecosystem is the Ministry of Power’s localized procurement directive. To qualify for VGF incentives, BESS developers must now ensure that a minimum of 20% of their procurement cost qualifies as local domestic content. This mandate is actively pushing global OEMs to collaborate with Indian technology partners to develop indigenous Energy Management System (EMS) software and localized supply chains.
• Streamlined Clearances for PSP Developers: Competition in the hydro-pumped storage segment is accelerating due to major "ease of doing business" reforms. The CEA has revised its guidelines for Detailed Project Reports (DPR), successfully cutting the concurrence timeline from 90 days down to 50 days. Additionally, the clearance of Inter-State Aspects is no longer required for PSPs, and the Ministry of Environment, Forest and Climate Change (MoEF&CC) has simplified environmental appraisals (enabling B2 category status) and relaxed forest survey restrictions, drastically lowering bureaucratic entry barriers for private sector players.
