🗞️ Why in News Waaree Energies, India’s largest solar photovoltaic module manufacturer, announced a Rs 8,175 crore battery energy storage gigafactory in Anakapalli, Andhra Pradesh, with a capacity of 16 GWh. The facility will manufacture lithium iron phosphate (LFP) battery cells, targeting grid-scale energy storage and electric vehicle applications.
Why India Urgently Needs Battery Manufacturing
India’s energy transition — moving from fossil fuels to renewable energy — faces a fundamental challenge: solar and wind energy are intermittent. The sun doesn’t always shine; the wind doesn’t always blow. The solution is energy storage: store surplus renewable electricity when generation exceeds demand, and release it when demand peaks.
Battery Energy Storage Systems (BESS) are currently the most scalable technology for this purpose. But India faces a paradox: despite being the world’s third-largest solar market, it imports almost all its batteries — primarily from China and to a lesser extent South Korea and Japan.
In 2023-24, India imported batteries worth over $5 billion — a strategic and economic vulnerability.
The ACC Battery Storage PLI scheme (Production Linked Incentive for Advanced Chemistry Cell) was launched specifically to change this.
The PLI for ACC Battery Storage — Framework
ACC (Advanced Chemistry Cell) is the government’s term for next-generation battery chemistries beyond traditional lead-acid. The PLI scheme was approved in May 2021 with a total outlay of ₹18,100 crore.
Key Parameters of the ACC PLI:
| Parameter | Details |
|---|---|
| Total outlay | ₹18,100 crore |
| Total capacity target | 50 GWh (domestic manufacturing) |
| Minimum investment per bidder | ₹225 crore/GWh |
| Domestic value addition requirement | 25% in Year 2, 35% in Year 3, 50% by Year 5 |
| Incentive rate | ₹20 lakh/MWh (₹2 crore/GWh) on net sales |
| Contract period | 5 years of incentive receipt |
| Operators selected | Ola Electric (20 GWh), Reliance Industries (5 GWh), Rajesh Exports (5 GWh) — initial round |
Waaree’s 16 GWh facility is part of ACC PLI Round 2 expansion.
What Is an LFP Battery? — The Technology
Lithium Iron Phosphate (LFP) batteries are one of several lithium-ion battery chemistries. The choice of cathode material is what differentiates them:
LFP vs. Other Lithium-Ion Chemistries
| Chemistry | Cathode | Energy Density | Safety | Cost | Application |
|---|---|---|---|---|---|
| LFP | LiFePO₄ | Moderate (150-200 Wh/kg) | Excellent (no thermal runaway) | Lowest | Grid storage, buses, commercial EVs |
| NMC | Li-Nickel-Manganese-Cobalt | High (200-300 Wh/kg) | Good | Higher | Premium EVs, consumer electronics |
| NCA | Li-Nickel-Cobalt-Aluminum | High (200-260 Wh/kg) | Moderate | High | Tesla (some models) |
| Solid-State | Solid electrolyte | Very High | Excellent | Very High (not commercial yet) | Next-gen EVs |
Why LFP for India’s context:
- Safety: Extremely thermally stable — critical for large grid installations in India’s hot climate
- Cycle life: 3,000-5,000 charge cycles vs. ~1,000-2,000 for NMC — ideal for daily cycling grid storage
- Cost: ~15-20% cheaper per kWh than NMC
- No Cobalt: Cobalt is ethically complex (DRC mining) and expensive; LFP avoids it
- Lifespan: 10-15 years for grid use
The trade-off: LFP has lower energy density than NMC, making it less suitable for small, lightweight applications where space is premium. For grid storage (which doesn’t need to be light) and buses/commercial vehicles, LFP is optimal.
Waaree Energies — Company Profile
Waaree Energies is headquartered in Mumbai and is India’s largest solar PV module manufacturer by installed capacity.
- Founded: 1989 (as a diversified group; solar business scaled from ~2010)
- Listed: NSE, BSE (IPO in October 2024)
- Solar module capacity: ~12 GW/year (as of 2025)
- Exports: Significant exporter to the USA and Europe (beneficiary of US buyers seeking non-Chinese solar supply chains)
- Expansion: IPO proceeds used to expand manufacturing at Surat (Gujarat) and the new battery facility at Anakapalli (AP)
The move into battery manufacturing is a natural adjacency — solar power and battery storage are deployed together as Solar + Storage projects, and Waaree can offer integrated solutions to utilities.
Grid-Scale Energy Storage — India’s Target
India has set a target of 500 GW of non-fossil fuel capacity by 2030 (under its Nationally Determined Contributions/NDCs updated in 2022). Achieving this requires massive grid-scale storage to handle:
- Duck curve: Solar generation peaks mid-day when demand is moderate; demand peaks in the evening when solar output drops — storage bridges this gap
- Seasonal imbalance: Wind energy peaks in monsoon months; solar in summer — storage balances seasonal variation
- Grid stability: Rapid frequency fluctuations from high renewable penetration need battery response (faster than gas peakers)
India’s Central Electricity Authority (CEA) estimates India will need 411 GWh of battery storage by 2030 — just to manage the 500 GW renewable integration target.
Currently installed BESS in India (2025): ~5-8 GWh — a massive gap.
Critical Minerals — The Underlying Challenge
LFP batteries require lithium (primary), iron, and phosphate. India has:
- Lithium: Minimal domestic reserves (largest known deposit: Reasi, Jammu & Kashmir — discovered 2023, estimated 5.9 million tonnes); major import dependence
- Iron: Abundant (4th largest reserves globally)
- Phosphate: Limited domestic reserves
The Critical Mineral Mission (announced in Budget 2024-25) aims to secure supply chains for lithium, cobalt, nickel, manganese, and other battery minerals through:
- Domestic exploration intensification
- Overseas mineral acquisitions (KABIL — Khanij Bidesh India Limited)
- Recycling ecosystem development (battery recycling = urban mining)
KABIL is a JV of NALCO, HCL, and MECL set up specifically to acquire strategic mineral assets abroad (Australia, Argentina, Chile, Bolivia — the “Lithium Triangle”).
