India Has a 260GWh Battery-Storage Tender Pipeline, and Just 2GWh of Commissioned Cell Capacity

New research from Wood Mackenzie puts a hard number on something I've suspected for a while: India's battery storage ambitions and India's battery storage capability are running on very different timelines. Despite more than 226GWh of cell manufacturing capacity announced for construction through 2035, the report estimates that a globally competitive, self-sufficient cell industry remains 10 to 15 years away. The number that stopped me, though, wasn't the long-run projection. It was the near-term one: Wood Mackenzie estimates that India's commissioned domestic cell-manufacturing capacity, just 2GWh, is equivalent to less than 1 percent of the roughly 260GWh demand pipeline associated with competitive battery-storage tenders in 2026. China, by comparison, has roughly 2,695GWh of cell-manufacturing capacity, more than 1,300 times India's current commissioned capacity.

I wrote recently about India's Production-Linked Incentive programme crossing ₹2.4 lakh crore in actual aggregate investment as of March 2026, and cautioned that the aggregate number hides real sector-level divergence. Battery cells are close to the clearest case of that divergence I've seen. The ₹18,100-crore Advanced Chemistry Cell (ACC) PLI scheme was designed to establish 50GWh of domestic ACC manufacturing capacity. Government data for October 2025 showed ₹2,878 crore of investment under the scheme, roughly a quarter of the investment then expected. As of August 2026, government data cited in reporting put operational ACC capacity under the scheme at 1.4GWh, all from Ola Electric, 2.8 percent of the scheme's overall 50GWh objective. Ola separately says it now has 2.5GWh of installed cell capacity, with a further 3.5GWh under installation, and expects to reach 6GWh by the end of this quarter. The government has since effectively extended the original timelines by two years for Ola Electric's and Reliance New Energy's first-round ACC commitments.

(Worth flagging: “installed,” “commissioned,” “operational,” and “commercial production” are being used slightly differently across these figures. That's not necessarily a contradiction, different organizations are measuring different things at different cut-off dates, but it's exactly the kind of distinction worth holding onto rather than treating these numbers as interchangeable.)

Why cells and packs are telling two different stories. Here's the distinction I think matters most for anyone reading the headline number: India's struggle is concentrated upstream, in cell manufacturing, which is capital-intensive, technically demanding, and still significantly dependent on Chinese and South Korean technology licensors. Downstream, the picture looks meaningfully better. India already has roughly 60GWh of installed domestic battery-pack manufacturing capacity, pack assembly is a more readily localisable downstream activity than cell manufacturing. A 20 percent domestic-content requirement now being applied to grid-scale BESS projects under new government-supported tenders is intended to support localisation of downstream components: enclosures, energy management systems, SCADA, battery packs. At that threshold, projects can in practice still use imported cells while meeting localisation requirements through other components.

The Indian experience suggests policy can accelerate assembly and integration relatively quickly, but cannot as easily compress the time it takes to build genuine upstream manufacturing depth, cell chemistry, materials processing, precision tooling. Locally made cells in India are still expected to cost 25 to 40 percent more than imported ones, with Wood Mackenzie attributing that premium principally to limited scale, higher financing costs, and an underdeveloped domestic supplier ecosystem. At the same time, Wood Mackenzie assesses India's underlying manufacturing-cost position as highly competitive, second only to China among major manufacturing locations, even though locally produced cells remain more expensive for now.

What this means for anyone planning around India's battery supply chain: Don't treat “battery manufacturing capacity” as one category, cell capacity and pack capacity are different maturity problems on different timelines, and a company sourcing packs faces a very different risk picture than one depending on domestically produced cells. Near-term domestic-content compliance appears substantially more achievable than cell self-sufficiency, plan sourcing strategy accordingly rather than assuming policy targets and operational reality will converge on the same schedule. And announced or awarded capacity shouldn't be treated as equivalent to commissioned capacity, the ACC experience is a clear reminder of that gap, and worth watching for in other capital-intensive PLI sectors too.

As Wood Mackenzie puts it, India's battery-storage ambitions are credible. But the gap between policy intent and operational capacity is wide, and closing it looks like a decade-scale project, not a budget-cycle one.
