India's battery industry faces years of dependence before achieving self-sufficiency, despite new incentives

India’s push for local battery component production is hitting delays and technological hurdles, with experts warning it could take over a decade to develop a fully indigenous cell manufacturing industry despite recent financial incentives and policy reforms.

On 27 August 2026, Bloomberg reported that New Delhi was nearing a fresh incentive package worth up to ₹13,000 crore for battery-component makers, shifting attention from finished cells to the materials and parts inside them. The change in emphasis amounts to an official recognition that India’s battery drive is still short on industrial depth: Wood Mackenzie said in research released a week earlier that the country remains 10 to 15 years away from a globally competitive, self-sufficient battery cell industry.

The gap between ambition and current output is wide. Wood Mackenzie said India had just 2 GWh of commissioned cell manufacturing capacity in 2026, representing less than 1% of an estimated 260 GWh demand pipeline from competitive tenders. More than 226 GWh of capacity has been announced through 2035, but execution delays, financing constraints and continued reliance on Chinese and South Korean technology licensors mean much of that pipeline still exists on paper rather than on factory floors. Ankita Chauhan, a director at Wood Mackenzie, said “the gap between policy intent and operational capacity is wide”. (woodmac.com)

That shortfall matters because forcing localisation too quickly would make storage materially more expensive. The Financial Express, citing Wood Mackenzie, reported that raising domestic-content rules for grid-scale battery energy storage projects from below 20% to 100% would add about 30% to capital expenditure for a benchmark 100 MW, two-hour system. Analysts therefore expect India to localise downstream products first, including containers, energy management systems and SCADA control systems, as well as battery packs, while more complex upstream inputs remain import-heavy. China’s lead frames the problem: it has 2,695 GWh of cumulative cell manufacturing capacity and controls between 85% and 98% of global capacity across cathodes, anodes, separators and electrolytes.

Official figures show why ministers are now broadening the policy response. The Ministry of Heavy Industries told Parliament in February 2026 that the Advanced Chemistry Cell production-linked incentive programme, approved in May 2021 with an outlay of ₹18,100 crore to build 50 GWh of domestic capacity, had awarded 40 GWh to four firms. But only one beneficiary, Ola Cell Technologies, had installed any capacity by 31 December 2025, at 1 GWh. The ministry said cumulative investment stood at ₹3,237 crore and employment at 1,118, while no beneficiary had yet claimed incentive payments. The International Energy Agency still listed the programme as in force in April 2026, describing it as a five-year scheme after a two-year gestation period. (pib.gov.in)

The proposed new subsidy attempts to plug the holes exposed by that record. Bloomberg reported that the planned support would extend to five upstream inputs: anode active materials, cathode active materials, electrolytes, separator film and copper foil. The proposal is due to go before the finance ministry’s Expenditure Finance Committee after inter-ministerial consultations. That focus mirrors the ministry’s own explanation for missed milestones: in a 10 February 2026 statement it cited unavailable technology, gaps in skilled manpower, dependence on imported machinery and the “non-availability of upstream components”.

Reliance Industries illustrates how national dependence on imported technology translates into corporate strategy. Bloomberg reported in May 2026 that Reliance was in talks with CATL and other global suppliers for battery energy storage system parts for its Jamnagar complex, potentially supplementing supplies from Xiamen Hithium after that partnership ran into roadblocks. The report said earlier talks with CATL on a technology-transfer arrangement had collapsed, pushing Reliance towards assembling pre-made cells into large storage systems rather than manufacturing the cells themselves as Beijing tightened controls on core battery technology exports. A Reliance spokesperson said: “Our company evaluates various opportunities on an ongoing basis,” and added that the company does not comment “on media speculation and rumors”.

The attraction of persevering is obvious. BloombergNEF projected that India’s energy storage market could reach 336.7 GWh by the end of 2035, around 115 times the cumulative installations recorded in 2025. That explains why, despite delays, companies are still trying to build positions. Bloomberg reported that Jamnagar is expected to become India’s biggest energy storage complex, while The Economic Times said Ola Electric had begun limited cell manufacturing and aimed to scale to about 6 GWh. The same report said Tata Group, Exide Industries and Amara Raja Energy & Mobility were also building or operating cell facilities outside the government aid programme.

For now, though, the most realistic path to localisation lies further down the chain than India originally hoped. Wood Mackenzie expects containers, battery packs and control systems to be the first meaningful areas of domestic manufacturing over the next two to three years, not a fully indigenous cell ecosystem. The government is still pressing ahead with the wider ACC scheme , in July 2026 the heavy industries ministry opened bidding for another 10 GWh of capacity earmarked for grid-scale stationary storage , but the new component plan shows where officials now see the real bottleneck. India may yet build a battery industry at scale, but first it has to learn to make far more of the chemistry, films and foils that determine whether a cell can be called Indian in anything more than name.
