India's domestic battery manufacturing currently represents less than 1% of its roughly 260 GWh demand pipeline from competitive tenders in 2026, leaving the nation structurally reliant on imports despite accelerating policy goals, according to a new Wood Mackenzie research report titled "Chasing Self-Sufficiency: Cost of Building an Indigenous Battery Storage Supply Chain in India." Although more than 226 GWh of cell manufacturing capacity has been announced for construction through 2035, execution delays, financial viability obstacles, and deep technology reliance on Chinese and Korean licensors mean India remains 10 to 15 years from achieving a globally competitive, self-sufficient cell industry.
The scale of the challenge is stark. India has just 2 GWh of commissioned cell manufacturing capacity as of 2026, compared with China's cumulative capacity of 2,695 GWh. China dominates between 85% and 98% of global capacity across every major supply chain component, spanning cathode, anode, separator, and electrolyte production. Locally manufactured cells are projected to cost 25% to 40% more than imported alternatives, driven by limited scale, higher financing expenses, and an underdeveloped supplier ecosystem. Financial viability presents another hurdle: a 5 GWh facility operates at negative 10% EBITDA, with breakeven achievable only at 10 GWh and positive margins requiring at least 20 GWh. Despite these obstacles, India's underlying cost position is globally competitive, offering a 154% cost advantage over Japan and a 9% advantage over South Korea, placing it second only to China among major manufacturing destinations.
"India's battery storage ambitions are credible, but the gap between policy intent and operational capacity is wide," said Ankita Chauhan, director at Wood Mackenzie. The report finds that the near-term opportunity lies in downstream components such as containers, energy management systems, and battery packs, where localisation is both technically feasible and commercially attractive. India is expected to prioritise these downstream components over the next two to three years, supported by a 20% domestic content requirement now applied to grid-scale battery energy storage system projects under new tenders. According to the research, scaling domestic content requirements from less than 20% to 100% adds approximately 30% total capital expenditure premium to a benchmark 100 MW, two-hour battery storage project. Nearly all players rely on Chinese or Korean technology licences, which limit their control over pricing and supply chains, and only four players have commissioned gigafactories in India as of 2026.
The report explains 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. Bridging the gap between India's current capacity and China's dominance will require a fundamental restructuring of the country's manufacturing ecosystem, according to Wood Mackenzie. The harder work of building a self-sufficient cell industry will take a decade or more and requires sustained, targeted investment that goes well beyond the incentive schemes currently in place, the report notes. "India's cost position is genuinely competitive in a global context, and that matters as supply chain diversification becomes a strategic imperative," said Priya Shrivastava, Senior Research Analyst at Wood Mackenzie. The challenge is closing the execution gap fast enough to capture that opportunity before other emerging manufacturing hubs do.
