ACC BATTERY PRODUCTION-LINKED INCENTIVE (PLI) SCHEME

1. At a Glance

• National Programme on Advanced Chemistry Cell (ACC) Battery Storage is a PLI scheme of the Ministry of Heavy Industries (MHI), approved May 2021, outlay ₹18,100 crore, to set up 50 GWh of domestic ACC manufacturing capacity [S1][S4].
• Flagship instrument for Aatmanirbhar Bharat in energy storage; underpins EV adoption, renewable integration, and import-substitution of ~₹20,000 crore/year in battery imports [S1].
• UPSC-relevant for GS-III (industrial policy, energy security, S&T) and Prelims (scheme architecture, beneficiaries, GWh figures).

2. Why in the News

• PIB release dated 27 March 2026 by MHI reported status of land acquisition and plant commissioning for beneficiary firms; only 1 GWh installed (Ola Cell Technologies) against 40 GWh awarded so far [S1].
• Cumulative investment ₹3,237 crore and employment 1,118 reported as of 31 Dec 2025 [S2].

3. Background & Evolution

• May 2021 — Union Cabinet approved the scheme [S4].
• March 2022 — Initial allotment of 50 GWh to 4 successful bidders under first bidding round [S3].
• July 2022 — Three companies signed Programme Agreements with MHI [S5].
• 2024 — Re-bidding for residual capacity; MHI awarded 10 GWh to one bidder (Reliance New Energy Battery Storage) under the supplementary round [S6].
• 2025-26 — Implementation phase; land acquisition completed by all four firms; capacity build-out lagging [S1].

4. Core Static Facts

• Name: National Programme on Advanced Chemistry Cell (ACC) Battery Storage [S1].
• Ministry: Ministry of Heavy Industries (MHI) — not MNRE, not MeitY [S1].
• Outlay: ₹18,100 crore [S1].
• Target capacity: 50 GWh ACC + (originally 5 GWh "Niche" ACC) [S1].
• Capacity awarded: 40 GWh to 4 firms (50 GWh including 10 GWh re-bid award) [S1][S6].
• Tenure: Incentive disbursal over 5 years after 2-year gestation for plant setup [S4].
• Beneficiary firms (current) [S1]: 1. ACC Energy Storage Pvt. Ltd. — 5 GWh awarded, 0 GWh installed. 2. Ola Cell Technologies Pvt. Ltd. — 20 GWh awarded, 1 GWh installed. 3. Reliance New Energy Battery Storage Ltd. — 5 GWh awarded, 0 GWh installed. 4. Reliance New Energy Battery Storage Ltd. (second tranche) — 10 GWh awarded.
• Original 2022 bidders: Reliance New Energy Solar Ltd., Ola Electric Mobility, Hyundai Global Motors, Rajesh Exports [S3].
• Expected import substitution: ~₹20,000 crore p.a. [S3].

5. Multi-Dimensional Analysis

Economic - Targets levelised cost competitiveness for battery cells; incentive tied to sales of locally-manufactured ACCs with minimum 25% domestic value addition (DVA) at start, rising to 60% in 5 years [S4]. - Cumulative private investment ₹3,237 crore (Dec 2025) — well below committed envelope, signalling slow ramp-up [S2].

Strategic / Energy Security - Reduces dependence on Chinese Li-ion cell imports; critical for EV mission and 500 GW non-fossil capacity by 2030 target [S1][S3]. - Complements PLI Auto & Auto Components (also MHI) and FAME-II demand-side push [S7].

Scientific / Technological - "Advanced Chemistry Cell" is technology-agnostic — covers Li-ion, sodium-ion, flow batteries, metal-air, solid-state [S4]. - Encourages R&D as DVA conditions tighten over time [S4].

Administrative - MHI is nodal; NITI Aayog was associated in design phase [S4]. - Implementation bottleneck: only Ola at 1 GWh installed by 2026 despite 2021 approval — execution risk evident [S1].

Environmental - Enables decarbonisation via grid-scale storage + EVs; lifecycle concerns around lithium mining and end-of-life recycling not addressed within scheme.

6. Recent Developments (last 12-18 months)

• 2024: 10 GWh capacity re-awarded to one bidder under supplementary bidding [S6].
• 31 Dec 2025: Cumulative investment ₹3,237 crore; 1,118 jobs reported [S2].
• 27 Mar 2026: MHI tabled commissioning status — Ola Cell Technologies first to operationalise (1 GWh) [S1].

• Cumulative actual investment as on 31 Dec 2025: ₹3,237 crore [S2].

8. Mains Relevance

• GS-III — Indian Economy (industrial policy, infrastructure); Science & Technology (indigenisation); Energy.
• Syllabus headings: "Effects of liberalization on the economy, changes in industrial policy"; "Achievements of Indians in S&T; indigenization of technology and developing new technology"; "Infrastructure: Energy".
• Probable stems: 1. "Critically examine the role of Production-Linked Incentive schemes in building India's battery storage ecosystem. What are the implementation challenges?" 2. "Discuss how the ACC PLI scheme aligns with India's energy transition commitments under the Panchamrit pledge." 3. "Indigenous Advanced Chemistry Cell manufacturing is a strategic imperative, not merely an industrial policy choice. Comment."

10. Common Errors / Trap Areas

• Wrong ministry: Often confused with MNRE or MeitY; it is Ministry of Heavy Industries.
• Outlay confusion: ₹18,100 crore (ACC) ≠ ₹25,938 crore (Auto PLI) ≠ ₹76,000 crore (Semicon).
• Target confusion: 50 GWh is manufacturing capacity, not storage deployment.
• Beneficiaries: Original 2022 list (Hyundai, Rajesh Exports) differs from current 2026 list (Reliance got additional 10 GWh via 2024 re-bid); aspirants quoting old PIB notes may err.
• "ACC" ≠ "Asbestos Cement Corp" or "Associated Cement Companies" — in this context strictly Advanced Chemistry Cell.
