India battery manufacturing cost-competitive but scale gap threatens 2026 demand
Synopsis
India is cost-competitive with Japan and South Korea on battery manufacturing — but that advantage is largely theoretical. With just 2 GWh of commissioned cell capacity against a 260 GWh demand pipeline, and China controlling up to 98% of global supply chain components, India's battery independence is realistically a decade or more away, Wood Mackenzie warns.
Key Takeaways
India offers a 154 per cent cost advantage over Japan and 9 per cent over South Korea in battery manufacturing, per Wood Mackenzie .
Locally made cells are still expected to cost 25–40 per cent more than imports in the near term due to scale and ecosystem gaps.
India has just 2 GWh of commissioned cell capacity in 2026 , against a demand pipeline of approximately 260 GWh .
China controls 85–98 per cent of global battery supply chain capacity across all major components.
India is estimated to be 10 to 15 years from a self-sufficient, globally competitive cell industry despite 226 GWh of announced capacity through 2035 .
Near-term localisation opportunity lies in downstream components — containers, EMS, and battery packs — according to Ankita Chauhan of Wood Mackenzie.
India's battery manufacturing sector is globally cost-competitive but structurally reliant on imports, and must urgently scale cell production to bridge a widening demand gap, according to a report released on Thursday, 20 August 2026 by energy research firm Wood Mackenzie. The findings highlight a sharp disconnect between India's policy ambitions and its operational manufacturing reality.
Where India Stands Globally
According to the Wood Mackenzie report, India offers a 154 per cent cost advantage over Japan and a 9 per cent advantage over South Korea, placing it second only to China among major battery manufacturing destinations. That competitive positioning, however, masks a structural vulnerability: locally manufactured cells are expected to cost 25–40 per cent more than imported alternatives in the near term, owing to limited scale, higher financing costs, and an underdeveloped supplier ecosystem.
The Scale Problem
India's domestic cell manufacturing currently accounts for less than 1 per cent of its approximately 260 GWh demand pipeline from competitive tenders in 2026. Against that backdrop, the country has just 2 GWh of commissioned cell manufacturing capacity as of 2026 — compared with China's cumulative capacity of 2,695 GWh. The shortfall leaves India structurally dependent on imports even as policy ambition accelerates.
Despite more than 226 GWh of cell manufacturing capacity announced for construction through 2035, execution delays, financial viability challenges, and deep technology dependence on Chinese and Korean licensors mean India remains an estimated 10 to 15 years from a globally competitive, self-sufficient cell industry, the report noted.
China's Chokehold on the Supply Chain
China controls between 85 per cent and 98 per cent of global capacity across every major battery supply chain component — from cathode to anode, separator, and electrolyte. Bridging that gap, the report argued, will require India to fundamentally restructure its manufacturing ecosystem rather than rely on incremental capacity additions.
The report forecast that cell manufacturing is expected to develop progressively with imported inputs over the next two to five years, while full refining capabilities will take more than ten years to establish.
What Industry Experts Said
Ankita Chauhan, Director at Wood Mackenzie, said: 'India's battery storage ambitions are credible, but the gap between policy intent and operational capacity is wide.' She added that 'the near-term opportunity lies in downstream components such as containers, EMS, and battery packs, where localisation is both technically feasible and commercially attractive.'
The Path Forward
The report's framing suggests a phased approach: near-term wins in downstream assembly and pack integration, medium-term cell manufacturing with imported inputs, and long-term refining self-sufficiency beyond a decade. This trajectory places India's battery independence well into the 2030s at the earliest — a timeline that will test the durability of current policy commitments as demand from electric vehicles and grid storage accelerates.
Point of View
Announced capacity, and then execution delays that leave import dependence intact. The 10-to-15-year timeline to self-sufficiency is not a counsel of despair — it is a calibration check. The risk is that EV and grid-storage demand scales faster than supply, locking in Chinese import dependency at exactly the moment India is trying to reduce it. Downstream localisation is the pragmatic near-term play, but it cannot substitute for the harder work of building cell chemistry and refining capabilities domestically.

Frequently Asked Questions
How cost-competitive is India in global battery manufacturing?
India ranks second only to China among major battery manufacturing destinations, offering a 154 per cent cost advantage over Japan and a 9 per cent advantage over South Korea, according to the Wood Mackenzie report released on 20 August 2026. However, locally manufactured cells are still expected to cost 25–40 per cent more than imports in the near term due to limited scale and an underdeveloped supplier ecosystem.
What is India's current battery cell manufacturing capacity?
India has just 2 GWh of commissioned cell manufacturing capacity as of 2026, against a domestic demand pipeline of approximately 260 GWh from competitive tenders. This means domestic cell production covers less than 1 per cent of current demand.
Why is India still dependent on battery imports despite cost advantages?
India's cost advantage has not yet translated into scale. Limited commissioned capacity, higher financing costs, execution delays on announced projects, and deep technology dependence on Chinese and Korean licensors keep the country structurally reliant on imports. The Wood Mackenzie report estimates full self-sufficiency is 10 to 15 years away.
What role does China play in the global battery supply chain?
China controls between 85 per cent and 98 per cent of global capacity across every major battery supply chain component, including cathode, anode, separator, and electrolyte. Reducing that dependence requires India to fundamentally restructure its manufacturing ecosystem, the report noted.
Where should India focus its battery manufacturing efforts in the near term?
According to Wood Mackenzie Director Ankita Chauhan, the near-term opportunity for India lies in downstream components such as containers, energy management systems (EMS), and battery packs, where localisation is described as both technically feasible and commercially attractive.
