The Production Linked Incentive (PLI) Scheme for Advanced Chemistry Cell (ACC) Battery Storage is a strategic initiative under the Ministry of Heavy Industries (MHI) designed to facilitate large-scale indigenous manufacturing of high-capacity energy storage systems. This scheme is critical for supporting the country’s transition to electric mobility and renewable energy integration.
Objectives of the ACC PLI Scheme
The primary goal is to shift India from importing finished battery cells to becoming a global manufacturing hub. The core objectives include:
- Reducing dependence on imported battery cells to enhance supply chain resilience.
- Facilitating the creation of a Giga-scale (Gigawatt-hour) battery manufacturing ecosystem within India.
- Strengthening the Make in India initiative by promoting domestic value addition.
- Providing a fillip to the Electric Vehicle (EV) segment and stationary energy storage sector.
- Leveraging advanced technology to achieve higher energy density and improved safety standards for battery applications.
Key Features and Structural Components
The scheme operates on a technology-agnostic basis, meaning it does not mandate a specific battery chemistry. However, it requires that the cell must meet defined performance criteria.
- Budgetary Outlay: The total financial outlay for this scheme is INR 18,100 crore.
- Incentive Period: The incentives are provided over a period of five years.
- Performance-Linked Mechanism: Incentives are disbursed based on sales, energy efficiency, cycle life, and the level of domestic value addition achieved by the manufacturer.
- Eligibility Requirement: Selected beneficiaries are required to set up a manufacturing facility with a minimum capacity of 5 GWh and meet a mandatory domestic value addition (DVA) threshold of 25% by the end of the second year, increasing to 60% by the end of the fifth year.
Comparison of Battery Storage Key Metrics
The scheme focuses on specific technical parameters that determine the quality and performance of ACCs.
| Metric | Requirement / Focus Area |
| Technology | Any advanced battery technology (Li-ion, Sodium-ion, Solid-state, etc.) |
| Minimum Capacity | 5 GWh per beneficiary |
| Domestic Value Addition | Incremental increase from 25% to 60% over 5 years |
| Performance Benchmarks | Energy density, cycle life, and specific power requirements |
Mandatory Domestic Value Addition (DVA)
The scheme mandates a phased increase in local sourcing to ensure that the manufacturing process is not merely an assembly of imported cells. The DVA requirement ensures that core components—such as electrodes, electrolytes, separators, and housing—are increasingly produced within India. Failure to meet these annual DVA targets results in a pro-rata reduction in the incentive payout.
Strategic Impact and Implementation
The implementation of this scheme is expected to have a cascading effect on the broader industrial landscape.
- Supply Chain Integration: By incentivizing the cell manufacturing layer, the scheme encourages the development of upstream industries for raw material processing and cathode/anode active material production.
- Energy Transition: The availability of cost-effective, locally manufactured batteries is essential for the stabilization of India’s power grid, particularly for large-scale integration of intermittent renewable energy sources like solar and wind.
- Technology Leadership: The scheme positions India to participate in the next generation of battery research and development, moving beyond legacy technologies.
Trivia for UPSC Aspirants
- Administrative Authority: The scheme is administered by the Ministry of Heavy Industries.
- Nature of Scheme: It is a sector-specific PLI scheme categorized under the umbrella of flagship industrial development programs.
- Technology Neutrality: The scheme does not specify the battery chemistry, provided the manufactured cells demonstrate the required minimum energy density and cycle life performance.
- Strategic Significance: India currently relies heavily on imports for its battery requirements; this scheme is the government’s primary mechanism to achieve import substitution in the critical energy storage sector.
