The Ministry of Heavy Industries has eased bidding norms and reduced subsidies under the PLI scheme for Advanced Chemistry Cell (ACC) battery storage, shifting focus from energy density to efficiency to boost grid-scale storage adoption.

Key points

PLI Scheme for ACC: The ₹18,100-crore Production Linked Incentive scheme aims to establish 50 GWh domestic manufacturing capacity for Advanced Chemistry Cells, crucial for India's energy storage and electric mobility goals.

Policy Shift: The latest 10 GWh tender for grid-scale storage reduces bidding thresholds (1-4 GWh vs 5-20 GWh earlier) and cuts subsidies from ₹2,000/kWh to ₹1,500/kWh, reflecting global cost reductions in battery manufacturing.

Technical Parameters: Evaluation now prioritizes energy efficiency (round-trip efficiency) over energy density, as grid storage isn't space-constrained but benefits from lower energy loss during charge-discharge cycles.

Domestic Value Addition: 70% weightage in technical bids is given to local content plans, despite India's lack of upstream component manufacturing capabilities for battery cells.

[GS3-Environment] The scheme supports India's renewable energy integration by enabling large-scale storage, critical for managing solar/wind power variability and achieving 500 GW non-fossil capacity by 2030.

Implementation Challenges: MHI cited technology unavailability, skilled manpower gaps, and import delays as reasons for previous awardees missing targets, highlighting supply chain vulnerabilities in battery manufacturing.

Bid Structure: Technical bids carry 80% weight (domestic value addition 70%, committed capacity 30%) while financial bids account for 20%, aiming to balance quality and cost considerations.

Way Forward: India should establish dedicated battery R&D centers under the National Mission on Transformative Mobility, create special economic zones for cell component manufacturing, and align PLI timelines with global raw material availability cycles.

Key terms

Advanced Chemistry Cells (ACC)

Next-generation energy storage technologies like lithium-ion, solid-state, and sodium-ion batteries that power EVs and grid storage. Their strategic importance lies in reducing oil imports (GS3 energy security) and enabling renewable integration (GS3 environment).

Grid-Scale Energy Storage

Large battery systems (1+ GWh) that store electricity for grid operators, crucial for managing renewable energy intermittency. In UPSC context, this connects to India's renewable targets and the need for ancillary services market reforms (GS3 infrastructure).

Domestic Value Addition

The percentage of a product's components sourced locally. For UPSC, this ties to Atmanirbhar Bharat, trade deficit reduction (GS3 economy), and the challenge of building mineral processing capabilities given India's lack of lithium/cobalt reserves.

Production Linked Incentive (PLI) Scheme

A performance-based subsidy program launched in 2021 to boost domestic manufacturing across 14 sectors including ACC batteries. For UPSC, it represents India's industrial policy shift from import substitution to export-oriented manufacturing, with ₹1.97 lakh crore allocated till 2026.
