The event underscored India's commitment to building a domestic battery value chain capable of supporting both the rapidly growing electric vehicle ecosystem and the nation's ambitious renewable energy storage targets.

A Strategic Fit for India's Energy and Industrial Future

India has set an ambitious goal of achieving 500 GW of non-fossil fuel capacity by 2030, with energy storage emerging as a critical enabler of the renewable transition. The Central Electricity Authority has projected deployment of 80 GW of Battery Energy Storage Systems (BESS) by FY2035-36 as part of India's long-term generation planning framework. According to the India Energy Storage Alliance, battery energy storage capacity additions in India are expected to surge nearly tenfold to approximately 5 GWh in 2026 from 507 MWh in 2025.

The Union Budget 2026-27 further reinforced this trajectory, with Finance Minister Nirmala Sitharaman extending basic customs duty exemptions on capital goods used for manufacturing lithium-ion cells, with the scope widened to include equipment deployed for Battery Energy Storage Systems. The budget also proposed adding 35 additional capital goods for EV battery manufacturing to the list of exempted capital goods.

The new prismatic battery production line directly supports this vision. Prismatic lithium-ion cells—flat, rectangular batteries known for their high energy density, superior thermal management, and space efficiency—are increasingly the cell format of choice for electric vehicles, stationary energy storage systems, and commercial and industrial applications. The Bengaluru facility will produce high-quality prismatic battery packs designed to serve both the domestic electric vehicle market and the burgeoning grid-scale energy storage sector.

Geographic Advantage and Growing Demand

India's geographic location in the global "sunbelt," characterized by high solar insolation, has driven rapid solar adoption across the country. India added nearly 24 GW of solar capacity between October 2025 and April 2026, taking total installed solar capacity to approximately 154 GW. However, renewable energy curtailment has emerged as a pressing challenge. Energy think tank Ember estimates that India requires approximately 10 GWh of battery storage to prevent renewable-energy curtailment at times when coal-based thermal power plants cannot ramp down below their minimum technical load.

Industry projections further reinforce this opportunity. MarkNtel Advisors projects the Indian BESS market to reach USD 1.2 billion by 2030, growing at a CAGR of 27 percent. Behind-the-meter stationary storage demand is projected to grow from 32 GWh in 2025 to over 39 GWh by 2033. By 2031-32, storage capacity demand is projected to increase to 73.93 GW, with BESS accounting for 47.24 GW.

Advanced Automation Equipment Powers the Production Line

The production line is equipped with a comprehensive suite of cutting-edge manufacturing and automation technologies designed specifically for high-precision prismatic battery pack assembly. The complete equipment roster includes:

1 OCV Testing, Sorting, and Code Scanning Station — Open Circuit Voltage (OCV) testing measures the voltage of each individual cell to ensure they meet required performance standards before assembly. The integrated sorting function segregates cells by performance characteristics, while code scanning establishes full traceability—creating a digital record for quality control and lifecycle tracking from the very first step of production.
1 5-Channel Sorting Machine — This high-throughput sorting system processes cells across five parallel channels, significantly increasing production efficiency by simultaneously classifying and routing cells based on their electrical performance metrics, ensuring that only matched cells proceed to module assembly.
1 Adhesive Coating Workstation — This station applies precise, uniform amounts of structural and thermal interface adhesives for cell stacking and module assembly—a critical process that ensures mechanical integrity and effective heat dissipation within the finished battery pack.
1 Stacking, Pressing, and Bundling Machine — This core assembly equipment performs the essential function of stacking prismatic cells into modules, applying controlled pressure to ensure optimal inter-cell contact, and bundling completed modules for downstream processing.
1 Code Scanning and Binding Device — This station provides additional traceability checkpoints while performing binding operations that secure module components, ensuring that every production step is documented within the manufacturing execution system.
1 Polarity Testing and Addressing Station — This critical safety and quality control station verifies correct cell polarity before final assembly and assigns unique electronic addresses to each battery module—enabling seamless integration with Battery Management Systems (BMS) for real-time monitoring and control.
1 Laser Welding and Liquid Cooling Plate Automatic Bonding Machine — This integrated station performs two essential functions: high-precision laser welding creates durable, low-resistance electrical connections between cells and busbars—a critical process that directly determines performance, safety, and cycle life—while the automatic bonding system applies and secures liquid cooling plates to battery modules, enabling advanced thermal management essential for maintaining optimal operating temperatures and extending battery life in high-performance applications.

Driving Localization, Employment, and Industrial Competitiveness

The new facility aligns with Prime Minister Narendra Modi's vision of Aatmanirbhar Bharat (self-reliant India) and reducing dependence on imported battery technologies. The Production Linked Incentive (PLI) scheme for Advanced Chemistry Cell (ACC) battery storage, approved in May 2021 with an outlay of ₹18,100 crore, aims to establish 50 GWh of domestic ACC manufacturing capacity. The government is also set to roll out a policy to develop a domestic processing value chain for battery minerals within the next three months.

The Ministry of Heavy Industries has mandated that Battery Management System (BMS) manufacturing be made fully domestic from September 1, 2026, with imports allowed only until August 31, 2026. This policy push, combined with the Union Budget's tariff exemptions on critical minerals including cobalt powder, lead, zinc, and lithium-ion battery scrap, is creating a robust ecosystem for domestic battery manufacturing.

The Bengaluru prismatic battery line is expected to create hundreds of skilled technical jobs in manufacturing, quality control, and engineering—contributing to India's growing pool of talent in advanced energy storage technologies. The facility will also stimulate the development of local supplier industries, from component manufacturing to maintenance services.

Supporting India's Electric Vehicle Revolution

India's electric vehicle market is expanding rapidly, with the government encouraging greater adoption of e-buses for public transport networks through payment security mechanisms. The Union Budget has continued tariff exemptions on lithium-ion components, reinforcing government support for domestic cell manufacturing at a time when EV adoption is accelerating across passenger vehicles, two-wheelers, and commercial segments.

The Bengaluru battery facility will supply critical battery pack components for both electric vehicles and stationary storage applications, complementing broader investments in EV and battery infrastructure across the country. Recent investments include Waaree Energies' announcement of a 16 GWh lithium-ion battery gigafactory in Andhra Pradesh with an investment of ₹8,175 crore, expected to generate around 3,000 direct jobs.
